You could try subclassing UIAlertView to add the field, or store a reference in your delegate class instead. But the most general way to attach any object to any other object is to use objc_setAssociatedObject. To do so, you have to #import <objc/runtime.h>, and you need an arbitrary void * that is used as a … Read more
Stupid me, I just have to set the alert view’s delegate to nil
Yes. Subclass UIAlertView and then overload -dismissWithClickedButtonIndex:animated:, e.g. @implementation MyAlertView -(void)dismissWithClickedButtonIndex:(NSInteger)buttonIndex animated:(BOOL)animated { if (buttonIndex should not dismiss the alert) return; [super dismissWithClickedButtonIndex:buttonIndex animated:animated]; } @end Unofficially you can define a -(void)alertSheet:(UIAlertSheet*)sheet buttonClicked:(id)button; method to the delegate which will make it bypass -dismissWithClickedButtonIndex:animated:, but it’s undocumented, so I don’t know whether it’s suitable for you.
The reason for this wait_fences: failed to receive reply: can also be that you try to show an alert while not being on the mainThread (which is the GUI thread). Dispatching to the GUI thread helps: dispatch_async(dispatch_get_main_queue(), ^{ [mainAlert show]; });
My call would be to add a category to UIAlertview adding the following function : – (void) hide { [self dismissWithClickedButtonIndex:0 animated:YES]; } And to suscribe to UIApplicationWillResignActiveNotification : [[NSNotificationCenter defaultCenter] addObserver:alertView selector:@selector(hide) name:@”UIApplicationWillResignActiveNotification” object:nil];
Amit89 brought a way to a solution up. You have to call the .windowproperty of the AppDelegate. So I changed the Swift code from the link below to work as intended to find the topmost ViewController. Make sure, that the view is already in the view hierarchy. So this method cannot be called from a … Read more
You can’t easily alter the view hierarchy of a UIAlertView in iOS 7. (Nor should you; the documentation specifically tells you not to.) Head over to the developer forums to see a long discussion about it. One alternative in your case is to set alert.alertViewStyle = UIAlertViewStylePlainTextInput; This will add a text field for you. … Read more
Under iOS 6 and above, these can be setup to show specific messages. Edit your Info.plist by adding a few new entries. The keys all begin with “Privacy – ” (the raw keys are NSxxxUsageDescription where xxx is Contacts, Locations, Reminders, PhotoLibrary, or Calendards). The value is the text you wish to display to the … Read more
Background of AlertView is an image And you can change this image UIAlertView *theAlert = [[[UIAlertView alloc] initWithTitle:@”Atention” message: @”YOUR MESSAGE HERE”, nil) delegate:nil cancelButtonTitle:@”OK” otherButtonTitles:nil] autorelease]; [theAlert show]; UILabel *theTitle = [theAlert valueForKey:@”_titleLabel”]; [theTitle setTextColor:[UIColor redColor]]; UILabel *theBody = [theAlert valueForKey:@”_bodyTextLabel”]; [theBody setTextColor:[UIColor blueColor]]; UIImage *theImage = [UIImage imageNamed:@”Background.png”]; theImage = [theImage stretchableImageWithLeftCapWidth:16 topCapHeight:16]; … Read more
Why not just check the visible property, maintained by the UIAlertView class? if (_alert) //alert is a retained property { self.alert = [[[UIAlertView alloc] initWithTitle:@”Your Title” message:@”Your message” delegate:self cancelButtonTitle:@”Cancel” otherButtonTitles:@”OK”] autorelease]; } if (!_alert.visible) { [_alert show]; }
