uiviewanimation

I have a UIView as container with a UILabel inside like this: ------------- --------- | | | | |Label text | |Label..| | | --> | | | | | | | | | | ------------- --------- Now when I use: UIView animateWithDuration:animations: and try to set the width smaller of the UIView (which contains the UILabel) then during the animation the UILabel suddenly replace with "..." without having smooth transition to it. I setup the UILabel autoresizingmask to UIViewAutoresizingFlexibleWidth, UIViewAutoresizingFlexibleRightMargin to keep it left and set the contentmode to left. Trying other content mode like

I am trying to make a little application in Xcode 4.2 targeting the iPhone. What I want is a UIButton that animates down the screen, and when you press it, you set it's alpha to 0. I found a method from the UIView class that was able to deal with user interactions, and came to this code: [UIView animateWithDuration:3.0 delay:0 options: UIViewAnimationOptionAllowUserInteraction | UIViewAnimationOptionAllowAnimatedContent animations: ^{ CGRect myRect = enemy1.frame; myRect.origin.y = 300; myButton.frame = myRect; } completion:nil]; Now, this does the animations properly, but the thing is that it

This is related to a lot of little bugs that might stereotypically be considered minor by one person, but major by another. What I've noticed more and more, is that when using all flavors a UIView animateWithDuration: , it actually modifies things unnecessarily, such multiple properties of my views', to do a simple hide/reveal style animations, etc..

I'm trying to animate a UITextField but I've been caught by a annoying and strange problem. My animation has the following sequence: In first state the application has the UITextField , the camera UIButton and the cancel UIButton after the camera button that is not been showed because it is been positioned out of the limits of the application. Actually my application has 320 of width and the cancel button origin is (350,7) In second state, when user touches on UITextField , the camera button alpha channel is set to 0 and the origin of cancel button is set to (247,7). The final state is the

I'm trying to make a simple Simon game (an increasing sequence of colors flash and the user has to try to repeat that sequence). The way I'm going about it is by having 4 UIViews with 8 images. So there's a UIView for red, blue, green, and yellow. And I have gifs of dark green, light green, dark red, light red, etc. So in my code, I'm using UIView's transitionWithView animation block: The UIView imageView.image is defaulted to the dark color image and this block is transitioning to light colored image, and on completion going back to the dark color image (to give it a "lighting up" look). -

I have the following 2 functions that add and remove child view controllers triggered from a container view controller: @discardableResult func addChildViewController(withChildViewController childViewController: UIViewController) -> UIViewController { // Add Child View Controller addChildViewController(childViewController) childViewController.beginAppearanceTransition(true, animated: true) // Add Child View as Subview view.addSubview(childViewController.view) // Configure Child View childViewController.view.frame = view.bounds childViewController.view.autoresizingMask = [.flexibleWidth,
