Comment puis-je créer un UIActivity
personnalisé dans iOS?
La raison pour laquelle je veux cela est d'ajouter un bouton Review App dans l'une de mes applications qui amène l'utilisateur à la section Review de l'App Store. Comment puis-je créer un tel UIActivity
personnalisé?
Créez d'abord les fichiers. J'ai choisi de nommer le mien ActivityViewCustomActivity
Donnez à ActivityViewCustomActivity.h l'aspect suivant:
#import <UIKit/UIKit.h>
@interface ActivityViewCustomActivity : UIActivity
@end
Donnez à ActivityViewCustomActivity.m l'aspect suivant:
#import "ActivityViewCustomActivity.h"
@implementation ActivityViewCustomActivity
- (NSString *)activityType
{
return @"yourappname.Review.App";
}
- (NSString *)activityTitle
{
return @"Review App";
}
- (UIImage *)activityImage
{
// Note: These images need to have a transparent background and I recommend these sizes:
// iPadShare@2x should be 126 px, iPadShare should be 53 px, iPhoneShare@2x should be 100
// px, and iPhoneShare should be 50 px. I found these sizes to work for what I was making.
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
return [UIImage imageNamed:@"iPadShare.png"];
}
else
{
return [UIImage imageNamed:@"iPhoneShare.png"];
}
}
- (BOOL)canPerformWithActivityItems:(NSArray *)activityItems
{
NSLog(@"%s", __FUNCTION__);
return YES;
}
- (void)prepareWithActivityItems:(NSArray *)activityItems
{
NSLog(@"%s",__FUNCTION__);
}
- (UIViewController *)activityViewController
{
NSLog(@"%s",__FUNCTION__);
return nil;
}
- (void)performActivity
{
// This is where you can do anything you want, and is the whole reason for creating a custom
// UIActivity
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"itms-apps://ax.iTunes.Apple.com/WebObjects/MZStore.woa/wa/viewContentsUserReviews?type=Purple+Software&id=yourappid"]];
[self activityDidFinish:YES];
}
@end
Voici à quoi ressemblait mon image: voici le .PSD que j'ai fait: - lien malveillant supprimé - et voici l'original 250 px .png http://i.imgur.com/pGWVj.png
Maintenant, dans votre contrôleur de vue, procédez comme suit:
#import "ActivityViewCustomActivity.h"
Et maintenant où vous voulez afficher votre UIActivityViewController
:
NSString *textItem = @"Check out the yourAppNameHere app: iTunes http link to your app here";
UIImage *imageToShare = [UIImage imageNamed:@"anyImage.png"];
NSArray *items = [NSArray arrayWithObjects:textItem,imageToShare,nil];
ActivityViewCustomActivity *aVCA = [[ActivityViewCustomActivity alloc]init];
UIActivityViewController *activityVC =
[[UIActivityViewController alloc] initWithActivityItems:items
applicationActivities:[NSArray arrayWithObject:aVCA]];
activityVC.excludedActivityTypes = @[UIActivityTypePostToWeibo, UIActivityTypeAssignToContact, UIActivityTypePrint, UIActivityTypeCopyToPasteboard, UIActivityTypeSaveToCameraRoll];
activityVC.completionHandler = ^(NSString *activityType, BOOL completed)
{
NSLog(@"ActivityType: %@", activityType);
NSLog(@"Completed: %i", completed);
};
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
self.popoverController = [[UIPopoverController alloc] initWithContentViewController:activityVC];
CGRect rect = [[UIScreen mainScreen] bounds];
[self.popoverController
presentPopoverFromRect:rect inView:self.view
permittedArrowDirections:0
animated:YES];
}
else
{
[self presentViewController:activityVC animated:YES completion:nil];
}
Voici ma version Swift - J'avais besoin de plusieurs actions personnalisées, j'ai donc créé cette classe. Pas besoin de délégués ou de protocoles.
1. Ajoutez la classe personnalisée
class ActivityViewCustomActivity: UIActivity {
var customActivityType = ""
var activityName = ""
var activityImageName = ""
var customActionWhenTapped:( (Void)-> Void)!
init(title: String, imageName:String, performAction: (() -> ()) ) {
self.activityName = title
self.activityImageName = imageName
self.customActivityType = "Action \(title)"
self.customActionWhenTapped = performAction
super.init()
}
override func activityType() -> String? {
return customActivityType
}
override func activityTitle() -> String? {
return activityName
}
override func activityImage() -> UIImage? {
return UIImage(named: activityImageName)
}
override func canPerformWithActivityItems(activityItems: [AnyObject]) -> Bool {
return true
}
override func prepareWithActivityItems(activityItems: [AnyObject]) {
// nothing to prepare
}
override func activityViewController() -> UIViewController? {
return nil
}
override func performActivity() {
customActionWhenTapped()
}
}
2 Utilisation dans votre View Controller
Je l'ai attaché à un UIBarButtonItem, qui appelle ce qui suit
@IBAction func actionButtonPressed(sender: UIBarButtonItem) {
var sharingItems = [AnyObject]() // nothing to share...
let myCustomActivity = ActivityViewCustomActivity(title: "Mark Selected", imageName: "removePin") {
println("Do something")
}
let anotherCustomActivity = ActivityViewCustomActivity(title: "Reset All", imageName: "reload") {
println("Do something else")
}
let activityViewController = UIActivityViewController(activityItems:sharingItems, applicationActivities:[myCustomActivity, anotherCustomActivity])
activityViewController.excludedActivityTypes = [UIActivityTypeMail, UIActivityTypeAirDrop, UIActivityTypeMessage, UIActivityTypeAssignToContact, UIActivityTypePostToFacebook, UIActivityTypePrint, UIActivityTypeCopyToPasteboard, UIActivityTypeSaveToCameraRoll]
activityViewController.popoverPresentationController?.barButtonItem = sender
self.presentViewController(activityViewController, animated: true, completion: nil)
}
Mon Swift Implémentation basée sur DogCoffee:
class ActivityViewCustomActivity: UIActivity {
// MARK: Properties
var customActivityType: UIActivityType
var activityName: String
var activityImageName: String
var customActionWhenTapped: () -> Void
// MARK: Initializer
init(title: String, imageName: String, performAction: @escaping () -> Void) {
self.activityName = title
self.activityImageName = imageName
self.customActivityType = UIActivityType(rawValue: "Action \(title)")
self.customActionWhenTapped = performAction
super.init()
}
// MARK: Overrides
override var activityType: UIActivityType? {
return customActivityType
}
override var activityTitle: String? {
return activityName
}
override class var activityCategory: UIActivityCategory {
return .share
}
override var activityImage: UIImage? {
return UIImage(named: activityImageName)
}
override func canPerform(withActivityItems activityItems: [Any]) -> Bool {
return true
}
override func prepare(withActivityItems activityItems: [Any]) {
// Nothing to prepare
}
override func perform() {
customActionWhenTapped()
}
}
Voici un exemple de mise en place d'une interface de messagerie composer à l'aide de la méthode -activityViewController de UIActivity. Cela montre comment mettre en place un viewController UIKit ou votre propre viewController personnalisé pour le but que vous choisissez. Il supplante le -performActivity, méthode.
#import <MessageUI/MessageUI.h>
#import <UIKit/UIKit.h>
@interface EPSuggestionsActivity : UIActivity <MFMailComposeViewControllerDelegate>
@end
@implementation EPSuggestionsActivity
....
- (UIViewController *)activityViewController{
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
NSString *emailAddress = @"[email protected]";
NSArray *toRecipients = @[emailAddress];
[picker setToRecipients:toRecipients];
[picker setSubject:@"Suggestions"];
return picker;
}
#pragma mark - MFMailComposeViewControllerDelegate Method
- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error {
[self activityDidFinish:YES]; // Forces the activityViewController to be dismissed
}
@end
Notez que -activityDidFinish est appelé à partir du délégué mail composer après que l'utilisateur a fermé l'interface de messagerie. Ceci est nécessaire pour faire disparaître l'interface UIActivityViewController. Si vous écrivez votre propre viewController, il aura besoin d'un déléguer la méthode qu'il appelle une fois terminé et vous devrez faire de votre sous-classe d'UIActivity le délégué.
