uiviewanimation

I have a UIview Containing two UIButtons. -(void)ViewDidLoad { geopointView = [[UIView alloc] initWithFrame:CGRectMake(0, 350, 120, 80)]; geopointView.backgroundColor = [UIColor greenColor]; UIButton *showGeoPointButton = [[UIButton buttonWithType:UIButtonTypeRoundedRect] retain]; showGeoPointButton.frame = CGRectMake(0, 0, 120, 40); showGeoPointButton.titleLabel.font = [UIFont systemFontOfSize:13.0]; [showGeoPointButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal]; [showGeoPointButton addTarget:self action:@selector(showPlaces:) forControlEvents

Im trying to swap to another root view controller with a tab bar; via app delegate, and I want to add transition animation. By default it would only show the view without any animation. let tabBar = self.instantiateViewController(storyBoard: "Main", viewControllerID: "MainTabbar") let appDelegate = UIApplication.shared.delegate as! AppDelegate appDelegate.window = UIWindow(frame: UIScreen.main.bounds) appDelegate.window?.rootViewController = tabBar appDelegate.window?.makeKeyAndVisible() That's how I swapped to another rootview controller. I evaluated UIView.transition(from: view, to: view)

I want to animate my photo gallery like the pages of the book. Is there any method with that I can use UIanimationtransitioncurl in either the left or right side? This is the code as you have suggested to me. I have done the allocation on the viewdidload method. self.title = @"TransitionsTitle"; // Create the container view which we will use for transition animation (centered horizontally). CGRect frame = CGRectMake(round((self.view.bounds.size.width - kImageWidth) / 2.0), kTopPlacement, kImageWidth, kImageHeight); self.containerView = [[[UIView alloc] initWithFrame:frame] autorelease]; [self

I am trying to use a custom segue to perform a kind of zoom animation. When the transition is executed, the sourceViewController goes black, then the zoom occurs. Tried also to set the pushViewController: into the completion block but the transition is not executed at all. - (void)perform { UIViewController *sourceViewController = (UIViewController *) self.sourceViewController; UIViewController *destinationViewController = (UIViewController *) self.destinationViewController; [destinationViewController.view setTransform:CGAffineTransformMakeScale(0.5,0.5)]; [destinationViewController.view

How to make this complex animation repeat and autoreverse? Is there any way to add options UIViewAnimationOptionAutoreverse | UIViewAnimationOptionRepeat to this animation sequence? [UIView animateWithDuration:1.0f animations:^{ someView.frame = someFrame1; } completion:^(BOOL finished) { [UIView animateWithDuration:0.5f animations:^{ someView.frame = someFrame2; } completion:nil]; }]; To animation from point 1 to 2 to 3 to 2 to 1 and repeat, you can do use animateKeyframesWithDuration in iOS 7 and later: someView.frame = frame1; [UIView animateKeyframesWithDuration:2.0 delay:0.0 options
