Comment partager une image sur Instagram sous iOS?

Mon client souhaite partager une image sur Instagram, Twitter, Facebook.

J'ai utilisé Twitter et Facebook, mais je n'ai trouvé aucune API ni aucune chose sur Internet pour partager une image sur Instagram. Est-il possible de partager une image sur Instagram? si oui alors comment?  

En consultant le site de développement d'Instagram, j'ai trouvé les bibliothèques de Ruby on Rails et de Python. Mais il n'y a pas de documentation sur iOS Sdk

Je reçois un jeton d'instagram selon instagram.com/developer mais je ne sais plus quoi faire pour la prochaine étape de partage avec l'image instagram.

Finalement j'ai eu la réponse. vous ne pouvez pas publier directement une image sur instagram. Vous devez rediriger votre image avec UIDocumentInteractionController. 

@property (nonatomic, retain) UIDocumentInteractionController *dic;    

CGRect rect = CGRectMake(0 ,0 , 0, 0);
UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, self.view.opaque, 0.0);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIGraphicsEndImageContext();
NSString  *jpgPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/test.igo"];

NSURL *igImageHookFile = [[NSURL alloc] initWithString:[[NSString alloc] initWithFormat:@"file://%@", jpgPath]];
self.dic.UTI = @"com.instagram.photo";
self.dic = [self setupControllerWithURL:igImageHookFile usingDelegate:self];
self.dic=[UIDocumentInteractionController interactionControllerWithURL:igImageHookFile];
[self.dic presentOpenInMenuFromRect: rect    inView: self.view animated: YES ];


- (UIDocumentInteractionController *) setupControllerWithURL: (NSURL*) fileURL usingDelegate: (id <UIDocumentInteractionControllerDelegate>) interactionDelegate {
     UIDocumentInteractionController *interactionController = [UIDocumentInteractionController interactionControllerWithURL: fileURL];
     interactionController.delegate = interactionDelegate;
     return interactionController;
}

NOTE: une fois que vous avez redirigé l'application instagram, vous ne pouvez plus revenir à votre application. vous devez ouvrir votre application à nouveau

Voici un code entièrement testé pour télécharger une image + un texte de légende sur Instagram ..

Fichier in.h

J'espère que cette réponse résoudra votre question. Cela ouvrira directement le dossier de la bibliothèque sur Instagram au lieu de Caméra.

NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL])
{
    NSURL *videoFilePath = [NSURL URLWithString:[NSString stringWithFormat:@"%@",[request downloadDestinationPath]]]; // Your local path to the video
    NSString *caption = @"Some Preloaded Caption";
    ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
    [library writeVideoAtPathToSavedPhotosAlbum:videoFilePath completionBlock:^(NSURL *assetURL, NSError *error) {
        NSString *escapedString   = [self urlencodedString:videoFilePath.absoluteString];
        NSString *escapedCaption  = [self urlencodedString:caption];
        NSURL *instagramURL = [NSURL URLWithString:[NSString stringWithFormat:@"instagram://library?AssetPath=%@&InstagramCaption=%@",escapedString,escapedCaption]];
        if ([[UIApplication sharedApplication] canOpenURL:instagramURL]) {
            [[UIApplication sharedApplication] openURL:instagramURL];
        }
    }];

Vous pouvez utiliser l'un des schémas fournis par Instagram

 enter image description here

  1. Instagram doc officiel ici

  2. Partager avec UIDocumentInteractionController

    final class InstagramPublisher : NSObject {

private var documentsController:UIDocumentInteractionController = UIDocumentInteractionController()

func postImage(image: UIImage, view: UIView, result:((Bool)->Void)? = nil) {
    guard let instagramURL = NSURL(string: "instagram://app") else {
        if let result = result {
            result(false)
        }
    return
}
    if UIApplication.sharedApplication().canOpenURL(instagramURL) {
        let jpgPath = (NSTemporaryDirectory() as NSString).stringByAppendingPathComponent("instagrammFotoToShareName.igo")
        if let image = UIImageJPEGRepresentation(image, 1.0) {
            image.writeToFile(jpgPath, atomically: true)
            let fileURL = NSURL.fileURLWithPath(jpgPath)
            documentsController.URL = fileURL
            documentsController.UTI = "com.instagram.exclusivegram"
            documentsController.presentOpenInMenuFromRect(view.bounds, inView: view, animated: true)
            if let result = result {
                result(true)
            }
        } else if let result = result {
            result(false)
        }
    } else {
        if let result = result {
            result(false)
        }
    }
    }
}

  3. Partager avec redirection directe

    import Photos

final class InstagramPublisher : NSObject {

func postImage(image: UIImage, result:((Bool)->Void)? = nil) {
guard let instagramURL = NSURL(string: "instagram://app") else {
    if let result = result {
        result(false)
    }
    return
}

let image = image.scaleImageWithAspectToWidth(640)

do {
    try PHPhotoLibrary.sharedPhotoLibrary().performChangesAndWait {
        let request = PHAssetChangeRequest.creationRequestForAssetFromImage(image)

        let assetID = request.placeholderForCreatedAsset?.localIdentifier ?? ""
        let shareURL = "instagram://library?LocalIdentifier=" + assetID

        if UIApplication.sharedApplication().canOpenURL(instagramURL) {
            if let urlForRedirect = NSURL(string: shareURL) {
                UIApplication.sharedApplication().openURL(urlForRedirect)
            }
        }
    }
} catch {
    if let result = result {
        result(false)
    }
}
}
}

  4. extension pour redimensionner la photo à la taille recommandée

    import UIKit

extension UIImage {
    // MARK: - UIImage+Resize

    func scaleImageWithAspectToWidth(toWidth:CGFloat) -> UIImage {
        let oldWidth:CGFloat = size.width
        let scaleFactor:CGFloat = toWidth / oldWidth

        let newHeight = self.size.height * scaleFactor
        let newWidth = oldWidth * scaleFactor;

        UIGraphicsBeginImageContext(CGSizeMake(newWidth, newHeight))
        drawInRect(CGRectMake(0, 0, newWidth, newHeight))
        let newImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return newImage
    }
}

  5. N'oubliez pas d'ajouter le schéma requis dans le plist

  <key>LSApplicationQueriesSchemes</key>
  <array>
       <string>instagram</string> 
  </array>

Pour iOS 6 et les versions ultérieures, vous pouvez utiliser cette UIActivity pour télécharger des images sur Instagram, qui a le même flux de travail à l'aide de points d'ancrage iOS mais simplifie le développement:

si vous ne voulez pas utiliser UIDocumentInteractionController 

import Photos

...

func postImageToInstagram(image: UIImage) {
        UIImageWriteToSavedPhotosAlbum(image, self, #selector(SocialShare.image(_:didFinishSavingWithError:contextInfo:)), nil)
    }
    func image(image: UIImage, didFinishSavingWithError error: NSError?, contextInfo:UnsafePointer<Void>) {
        if error != nil {
            print(error)
        }

        let fetchOptions = PHFetchOptions()
        fetchOptions.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: false)]
        let fetchResult = PHAsset.fetchAssetsWithMediaType(.Image, options: fetchOptions)
        if let lastAsset = fetchResult.firstObject as? PHAsset {
            let localIdentifier = lastAsset.localIdentifier
            let u = "instagram://library?LocalIdentifier=" + localIdentifier
            let url = NSURL(string: u)!
            if UIApplication.sharedApplication().canOpenURL(url) {
                UIApplication.sharedApplication().openURL(NSURL(string: u)!)
            } else {
                let alertController = UIAlertController(title: "Error", message: "Instagram is not installed", preferredStyle: .Alert)
                alertController.addAction(UIAlertAction(title: "OK", style: .Default, handler: nil))
                self.presentViewController(alertController, animated: true, completion: nil)
            }

        }
    }

c’est la bonne réponse que j’implémente avec les détails. Dans le fichier .h

 UIImageView *imageMain;
 @property (nonatomic, strong) UIDocumentInteractionController *documentController;

fichier in.m seulement écrire

 NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];
 if([[UIApplication sharedApplication] canOpenURL:instagramURL])
 {
      CGFloat cropVal = (imageMain.image.size.height > imageMain.image.size.width ? imageMain.image.size.width : imageMain.image.size.height);

      cropVal *= [imageMain.image scale];

      CGRect cropRect = (CGRect){.size.height = cropVal, .size.width = cropVal};
      CGImageRef imageRef = CGImageCreateWithImageInRect([imageMain.image CGImage], cropRect);

      NSData *imageData = UIImageJPEGRepresentation([UIImage imageWithCGImage:imageRef], 1.0);
      CGImageRelease(imageRef);

      NSString *writePath = [NSTemporaryDirectory() stringByAppendingPathComponent:@"instagram.igo"];
      if (![imageData writeToFile:writePath atomically:YES]) {
      // failure
           NSLog(@"image save failed to path %@", writePath);
           return;
      } else {
      // success.
      }

      // send it to instagram.
      NSURL *fileURL = [NSURL fileURLWithPath:writePath];
      self.documentController = [UIDocumentInteractionController interactionControllerWithURL:fileURL];
      self.documentController.delegate = self;
      [self.documentController setUTI:@"com.instagram.exclusivegram"];
      [self.documentController setAnnotation:@{@"InstagramCaption" : @"We are making fun"}];
      [self.documentController presentOpenInMenuFromRect:CGRectMake(0, 0, 320, 480) inView:self.view animated:YES];
 }
 else
 {
      NSLog (@"Instagram not found");

 }

Bien sûr, vous obtiendrez un résultat. Par exemple, vous verrez apparaître l'image du bas avec l'image d'instagram. Cliquez dessus et amusez-vous.

J'ai essayé cela dans mon application et cela fonctionne parfaitement (Swift)

import Foundation

import UIKit

class InstagramManager: NSObject, UIDocumentInteractionControllerDelegate {

    private let kInstagramURL = "instagram://"
    private let kUTI = "com.instagram.exclusivegram"
    private let kfileNameExtension = "instagram.igo"
    private let kAlertViewTitle = "Error"
    private let kAlertViewMessage = "Please install the Instagram application"

    var documentInteractionController = UIDocumentInteractionController()

    // singleton manager
    class var sharedManager: InstagramManager {
        struct Singleton {
            static let instance = InstagramManager()
        }
        return Singleton.instance
    }

    func postImageToInstagramWithCaption(imageInstagram: UIImage, instagramCaption: String, view: UIView) {
        // called to post image with caption to the instagram application

        let instagramURL = NSURL(string: kInstagramURL)
        if UIApplication.sharedApplication().canOpenURL(instagramURL!) {
            let jpgPath = (NSTemporaryDirectory() as NSString).stringByAppendingPathComponent(kfileNameExtension)
            UIImageJPEGRepresentation(imageInstagram, 1.0)!.writeToFile(jpgPath, atomically: true)
            let rect = CGRectMake(0,0,612,612)
            let fileURL = NSURL.fileURLWithPath(jpgPath)
            documentInteractionController.URL = fileURL
            documentInteractionController.delegate = self
            documentInteractionController.UTI = kUTI

            // adding caption for the image
            documentInteractionController.annotation = ["InstagramCaption": instagramCaption]
            documentInteractionController.presentOpenInMenuFromRect(rect, inView: view, animated: true)
        }
        else {

            // alert displayed when the instagram application is not available in the device
            UIAlertView(title: kAlertViewTitle, message: kAlertViewMessage, delegate:nil, cancelButtonTitle:"Ok").show()
        }
    }
}


 func sendToInstagram(){

     let image = postImage

             InstagramManager.sharedManager.postImageToInstagramWithCaption(image!, instagramCaption: "\(description)", view: self.view)

 }

Voici la bonne réponse. vous ne pouvez pas publier directement une image sur Instagram. Vous devez rediriger vers Instagram en utilisant UIDocumentInteractionController ...

NSString* imagePath = [NSString stringWithFormat:@"%@/instagramShare.igo", [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject]];
[[NSFileManager defaultManager] removeItemAtPath:imagePath error:nil];

UIImage *instagramImage = [UIImage imageNamed:@"imagename you want to share"];
[UIImagePNGRepresentation(instagramImage) writeToFile:imagePath atomically:YES];
NSLog(@"Image Size >>> %@", NSStringFromCGSize(instagramImage.size));

self.dic=[UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:imagePath]];
self.dic.delegate = self;
self.dic.UTI = @"com.instagram.exclusivegram";
[self.dic presentOpenInMenuFromRect: self.view.frame inView:self.view animated:YES ];

}

REMARQUE: une fois que vous avez redirigé l'application instagram, vous ne pouvez plus revenir à votre application. vous devez ouvrir votre application à nouveau

Vous pouvez le faire sans utiliser le UIDocumentInteractionController et aller directement à Instagram avec ces 3 méthodes:

Cela fonctionne comme toutes les autres applications célèbres… .. Le code est écrit en Objective C, vous pouvez donc le traduire en Swift si vous le souhaitez… .. Ce que vous devez faire, c'est enregistrer votre image sur l'appareil et l'utiliser un URLScheme

ajoutez ceci dans votre fichier .m

#import <Photos/Photos.h>

Vous devez d’abord enregistrer votre UIImage sur le périphérique avec cette méthode:

-(void)savePostsPhotoBeforeSharing
{
    UIImageWriteToSavedPhotosAlbum([UIImage imageNamed:@"image_file_name.jpg"], self, @selector(image:didFinishSavingWithError:contextInfo:), NULL);
}

Cette méthode est le rappel pour enregistrer l'image sur votre appareil:

- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo: (void *) contextInfo;
{
    [self sharePostOnInstagram];

}

Une fois l'image enregistrée sur le périphérique, vous devez interroger l'image que vous venez de sauvegarder et l'obtenir sous forme de PHAsset.

-(void)sharePostOnInstagram
{
    PHFetchOptions *fetchOptions = [PHFetchOptions new];
    fetchOptions.sortDescriptors = @[[NSSortDescriptor sortDescriptorWithKey:@"creationDate" ascending:NO],];
    __block PHAsset *assetToShare;
    PHFetchResult *result = [PHAsset fetchAssetsWithMediaType:PHAssetMediaTypeImage options:fetchOptions];
    [result enumerateObjectsUsingBlock:^(PHAsset *asset, NSUInteger idx, BOOL *stop) {
        assetToShare = asset;


    }];


    if([assetToShare isKindOfClass:[PHAsset class]])
    {
        NSString *localIdentifier = assetToShare.localIdentifier;
        NSString *urlString = [NSString stringWithFormat:@"instagram://library?LocalIdentifier=%@",localIdentifier];
        NSURL *instagramURL = [NSURL URLWithString:urlString];
        if ([[UIApplication sharedApplication] canOpenURL: instagramURL])
        {
            [[UIApplication sharedApplication] openURL: instagramURL];
        } else
        {
            // can not share with whats app
            NSLog(@"No instagram installed");
        }

    }
}

Et n'oubliez pas de mettre ceci dans votre info.plist sous LSApplicationQueriesSchemes

<string>instagram</string>

Quant à moi, le meilleur et le plus simple des moyens décrits ici Partager une photo sur Instagram depuis mon application iOS

Vous devez enregistrer l'image sur l'appareil au format .igo, puis utiliser "UIDocumentInteractionController" pour envoyer l'application Instagram à chemin d'accès local. N'oubliez pas de définir "UIDocumentInteractionControllerDelegate"

Mon conseil est d'ajouter quelque chose comme:

NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL]) 
{
 <your code>
}

NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];

if ([[UIApplication sharedApplication] canOpenURL:instagramURL])
{

    NSString  *jpgPath = [NSHomeDirectory() stringByAppendingPathComponent:[NSString stringWithFormat:@"Documents/Insta_Images/%@",@"shareImage.png"]];


    NSURL *igImageHookFile = [[NSURL alloc] initWithString:[[NSString alloc] initWithFormat:@"file://%@", jpgPath]];


    docController.UTI = @"com.instagram.photo";

    docController = [self setupControllerWithURL:igImageHookFile usingDelegate:self];

    docController =[UIDocumentInteractionController interactionControllerWithURL:igImageHookFile];

    docController.delegate=self;

    [docController presentOpenInMenuFromRect:CGRectMake(0 ,0 , 612, 612) inView:self.view animated:YES];

J'ai remarqué que si vous mettez URL en pointant sur l'image sur activityItems au lieu de UIImage, l'activité Copy to Instagram apparaît elle-même et vous n'avez rien d'autre à faire. Veuillez noter que les objets String à l'intérieur de activityItems seraient ignorés et qu'il n'y a aucun moyen de pré-remplir une légende dans Instagram. Si vous voulez toujours laisser entendre à l'utilisateur de publier une légende particulière, vous devez créer une activité personnalisée dans laquelle vous copiez ce texte dans le presse-papiers et que vous le laissez savoir, comme dans this Gist .

J'ai utilisé ce code:

    NSString* filePathStr = [[NSBundle mainBundle] pathForResource:@"UMS_social_demo" ofType:@"png"];
NSURL* fileUrl = [NSURL fileURLWithPath:filePathStr];

NSString  *jpgPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/test.igo"];
[[NSData dataWithContentsOfURL:fileUrl] writeToFile:jpgPath atomically:YES];

NSURL* documentURL = [NSURL URLWithString:[NSString stringWithFormat:@"file://%@", jpgPath]];

UIDocumentInteractionController *interactionController = [UIDocumentInteractionController interactionControllerWithURL: documentURL];
self.interactionController = interactionController;
interactionController.delegate = self;
interactionController.UTI = @"com.instagram.photo";
CGRect rect = CGRectMake(0 ,0 , 0, 0);
[interactionController presentOpenInMenuFromRect:rect inView:self.view animated:YES];
