viewdidappear

I have created a custom MKAnnotation class and it has been working - until iOS 6 came out. Since then my pins get added to the apple map but now without a drop animation! Is this how it is set or there maybe an an issue with the way I'm doing things. I have set a delay of 1 sec until the method that adds the annotations to the map is called, so I can see if the drop animations are actually occurring before the view appears - still, the pins just appear out of nowhere without dropping. Here's the code I'm using: -(MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(Annotation*

Update: This has been answered. It was my own stupidity, possibly not worth reading any more of this question. lol. Question: Right so i have this UIViewController(master) subclass, it has a UIImagepickerController(camera), it also has a UIView(overlayView). Master setups the camera to be configured as a camera only with a custom cameraOverlay, hiding the custom controls e.t.c. All appears to work fine apart from when i try to programatically take a picture. What happens is the overlayView calls the master and this triggers the take picture, then i hear the shutter sound and the iris closes,

A UIViewController (View A) invokes another view controller (View B) by invoking it as a modal control. [self presentModalViewController:ViewB animated:TRUE]; And View B exists by invoking: [self dismissModalViewControllerAnimated:TRUE]; When this occurs everything looks right EXCEPT that View A's viewWillAppear and viewDidAppear does not get called (they are called during app init though). Weird thing is... i believe ive done this before, but im not sure what is going on now. Is there anything obviously wrong that im doing? Thanks! * UPDATE * I just now learned that this behavior only occurs

This question already has answers here : Closed last year . Difference between viewDidLoad and viewDidAppear (2 answers) Bottom line is, I've been working on an app, and it seems that if I place a UIAlert in viewDidLoad , it gets called twice (from a delegate method of UIImagePickerController ). If I put it in viewDidAppear , it gets called once. I've looked through documentation but it just confuses me. A UIView object can get loaded into memory and released multiple times without ever getting added to the view stack and appearing on the display. My guess is that you have 2 references to this

I tried to add a animation to viewDidLoad and viewDidAppear, but it doesn't work: - (void)viewDidAppear:(BOOL)animated{ [UIView beginAnimations:@"transition" context:NULL]; [UIView setAnimationTransition:110 forView:self.view cache:YES]; [UIView commitAnimations]; } Why? jackbravo I had the same problem and I think I found the solution on this SO question . When viewDidAppear gets called you still don't see anything on the screen (despite the name), but you are about to. You can then use a performSelector:withDelay or an NSTimer to launch your animation. The delay can just be 0.1 and your

I have a UITableViewController in my app, which is added to the view hierarchy directly. After the view appears, I want to scroll to a specific cell. My solution would be to call the code for scrolling in -[viewDidAppear] . According to Apple's docs I have to call the method manually: If the view belonging to a view controller is added to a view hierarchy directly, the view controller will not receive this message. If you insert or add a view to the view hierarchy, and it has a view controller, you should send the associated view controller this message directly. The question is: When is the
