Le code ci-dessous fonctionne sur iOS6 (et les versions antérieures), mais UITextField ne s'affiche pas dans iOS7 ... aucune idée sur la manière d'afficher un UITextField dans un UIAlterView dans iOS7?
UIAlertView* dialog = [[UIAlertView alloc] init];
[dialog setDelegate:self];
[dialog setTitle:@"Enter ESC Score"];
[dialog setMessage:@" "];
[dialog addButtonWithTitle:@"Cancel"];
[dialog addButtonWithTitle:@"OK"];
dialog.tag = 5;
nameField = [[UITextField alloc] initWithFrame:CGRectMake(20.0, 45.0, 245.0, 25.0)];
[nameField setKeyboardType:UIKeyboardTypeNumberPad];
[nameField becomeFirstResponder];
[nameField setBackgroundColor:[UIColor whiteColor]];
[dialog addSubview:nameField];
CGAffineTransform moveUp = CGAffineTransformMakeTranslation(0.0, 0.0);
[dialog setTransform: moveUp];
[dialog show];
[dialog release];
[nameField release];
Le code exécuté pour iOS6 affiche ceci:
le même code dans iOS7 affiche ceci (remarquez comment UITextField est manquant et qu'il n'y a pas de clavier):
Vous ne pouvez pas facilement modifier la hiérarchie de vues d'un UIAlertView dans iOS 7. (La documentation vous le recommande tout particulièrement.) Rendez-vous sur les forums de développeurs pour consulter un long débat à ce sujet.
Une alternative dans votre cas consiste à définir alert.alertViewStyle = UIAlertViewStylePlainTextInput;
. Cela ajoutera un champ de texte pour vous. Vous pouvez y accéder dans le rappel de délégué UIAlertView en utilisant UITextField *textField = [alertView textFieldAtIndex:0];
.
@ Aaron Brager avait la bonne solution. En outre, j'ai ajouté une ligne après sa suggestion de définir un clavier numérique par défaut.
UIAlertView* dialog = [[UIAlertView alloc] init];
[dialog setDelegate:self];
[dialog setTitle:@"Enter ESC Score"];
[dialog setMessage:@" "];
[dialog addButtonWithTitle:@"Cancel"];
[dialog addButtonWithTitle:@"OK"];
dialog.tag = 5;
dialog.alertViewStyle = UIAlertViewStylePlainTextInput;
[dialog textFieldAtIndex:0].keyboardType = UIKeyboardTypeNumberPad;
CGAffineTransform moveUp = CGAffineTransformMakeTranslation(0.0, 0.0);
[dialog setTransform: moveUp];
[dialog show];
[dialog release];
UIAlertView *alertView = [[UIAlertView alloc]
initWithTitle:@"Credit Card Number"
message:@"Please enter your credit card number:"
delegate:self
cancelButtonTitle:@"Cancel"
otherButtonTitles:@"Ok", nil];
[alertView setAlertViewStyle:UIAlertViewStylePlainTextInput];
/* Display a numerical keypad for this text field */
UITextField *textField = [alertView textFieldAtIndex:0];
textField.keyboardType = UIKeyboardTypeNumberPad;
[alertView show];
Je travaille comme un charme
Deux UITextField dans UIAlertView pour toutes les versions d'iOS
-(IBAction) showAlertView {
UIAlertView *alert;
UITextField *callForwardNumber;
UItextField *callForwardCondition;
alert = [[UIAlertView alloc] initWithTitle:@"Enter Phone Number & Rule"
message:@""
delegate:self
cancelButtonTitle:@"Cancel"
otherButtonTitles:@"Save", nil];
//alert.transform = CGAffineTransformMakeTranslation(0, 110);
callForwardNumber = [[UITextField alloc] init];
callForwardNumber.keyboardType = UIKeyboardTypeNumberPad;
callForwardNumber.text = [R.prefs objectForKey:@"fwd_number"];
callForwardNumber.borderStyle = UITextBorderStyleRoundedRect;
callForwardNumber.delegate = self;
callForwardNumber.tag = 1;
callForwardCondition = [[UITextField alloc] init];
callForwardCondition.text = callCondition;
callForwardCondition.borderStyle = UITextBorderStyleRoundedRect;
callForwardCondition.delegate = self;
callForwardCondition.tag = 2;
[callForwardCondition setKeyboardType:UIKeyboardTypeNumberPad];
if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {
UIView* customAccessory =
[[UIView alloc] initWithFrame:CGRectMake(0, 0, 250, 55)];
callForwardNumber.frame = CGRectMake(0, 0, 245.0, 25.0);
callForwardCondition.frame = CGRectMake(0, 30.0, 245.0, 25.0);
[customAccessory addSubview:callForwardNumber];
[customAccessory addSubview:callForwardCondition];
[alert setValue:customAccessory forKey:@"accessoryView"];
[alert show];
} else {
alert.message = @"\n\n\n";
[alert show];
callForwardNumber.frame = CGRectMake(20.0, 45.0, 245.0, 25.0);
callForwardCondition.frame = CGRectMake(20.0, 75.0, 245.0, 25.0);
[alert addSubview:callForwardNumber];
[alert addSubview:callForwardCondition];
}
}
Vous pouvez également consulter le contrôle personnalisé sur cocoacontrols.com. Regardez MLAertView (ios 7 comme interface utilisateur) et TSAlertView (ios 6 comme interface utilisateur). Ils peuvent également être transformés en angle de rotation.
1) En méthode - (id) initWithAlertTitle: (NSString *) title checkForPassword: (NSString *) mot de passe
vous devriez ajouter
self.alertViewStyle = UIAlertViewStylePlainTextInput;
échantillon:
(id)initWithAlertTitle:(NSString *)title
checkForPassword:(NSString *)password{
if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0"))
{
self.alertViewStyle = UIAlertViewStylePlainTextInput;
}
self = [super initWithTitle:title
message:@"" // password field will go here
delegate:self
cancelButtonTitle:@"Cancel"
otherButtonTitles:@"Enter", nil];
if (self) {
self.password = password;
self.hashTechnique = HashTechniqueNone; // use no hashing by default
secondMessage = @"Please Enter New Password";
thirdMessage = @"Please Re-Enter Password";
secondMessageNew = @"Please Enter Password";
}
NSLog(@" _password_ %@",_password);
NSLog(@"_old_password_ %@",[[NSUserDefaults standardUserDefaults] objectForKey:kPassword]);
return self;
}
dans la méthode show add next
(void)show {
if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0"))
{
UITextField *passwordField = [self textFieldAtIndex:0];
passwordField.delegate = self;
self.passwordField = passwordField;
}
else
{
UITextField *passwordField = [[UITextField alloc] initWithFrame:CGRectMake(14, 45, 256, 25)];
passwordField.secureTextEntry = YES;
passwordField.placeholder = @"";
passwordField.backgroundColor = [UIColor whiteColor];
// Pad out the left side of the view to properly inset the text
UIView *paddingView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 6, 19)];
passwordField.leftView = paddingView;
passwordField.leftViewMode = UITextFieldViewModeAlways;
// // Set delegate
self.passwordField.delegate = self;
// Set as property
self.passwordField = passwordField;
// Add to subview
[self addSubview:_passwordField];
}
// Show alert
[super show];
}

Je suis également confronté au même problème. Pendant le surf, la réponse a fonctionné pour moi. J'espère que ça marche aussi pour vous.
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Folder Name?" message:@"" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Ok", nil];
alertView.tag = 2;
alertView.alertViewStyle = UIAlertViewStylePlainTextInput;
[alertView show];
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
UITextField * alertTextField = [alertView textFieldAtIndex:0];
NSLog(@"alerttextfiled - %@",alertTextField.text);
}
