uiviewanimation

I have had a simple UIView block animation that handles animating a group of text fields into view when the keyboard will show (and animate them back when the keyboard hides). This has worked fine in iOS 6 & 7, but now I'm getting incorrect behavior, and it all points to some change in UIKeyboardWillShowNotification . I set up an isolated project to test this further on a single text field, with two buttons that call exactly the same methods that are fired for the keyboard's WillShow and WillHide notifications. See the results in this video: Video example This seems like a bug to me, or it

Please help out a beginner iOS developer here! :) So, I have a timer which gets the latitude and longitude of a bus periodically from a xml sheet which provides real-time locations of the bus. I was able to setup the parser, animate the bus movement and setup a custom (arrow) image for the bus. However, the problem is, I'm not able to able to rotate the bus-annotation everytime I get new values for the latitude and longitude. The busAnnotation rotates only when the program starts, but not everytime the direction of the bus is updated. Below is my xml parser function, which calculates the

I have the following block of code to fade out an introView(UIView) // Hide intro view after 5 seconds [UIView animateWithDuration: 1.0 delay: 5.0 options: (UIViewAnimationOptionAllowUserInteraction |UIViewAnimationOptionCurveLinear) animations: ^{ introView.alpha = 0; } completion: ^(BOOL finished) { [introView removeFromSuperview]; }]; I have a skip button inside the introVew but there is no interaction whatsoever, am I missing something?

Ive seen this effect in 2 apps and I REALLY want to find how to do it. The animation is in a UIBarButtonItem, and is only to the image. The image is a + symbol, and it rotates to a X. If you want to see the effect you have to start a conversation with someone and next to the text input theres the + button for images and emoji's. Or heres a video of the effect in another app, after he taps the bar button you see it rotate to a X, http://www.youtube.com/watch?v=S8JW7euuNMo . I have found out how to do the effect but only on a UIImageView, I have to turn off all the autoresizing and the view mode

I want to animate my UIProgressView progression from 0 to 1 during 10 seconds. Code: [UIView animateWithDuration:10.0 animations:^{ [_myProgressView setProgress:1 animated:YES]; } completion:(BOOL finished)^{ if (finished) NSLog(@"animation finished); }]; Animation is working fine except that completion and NSLog are always called instantly. I tried animateWithDuration: withDelay: but the delay is not respected and executed immediately. Has anyone encountered the same problem? Thanks for you help. paresh Its an old problem but I am still posting the solution here. The solution turned out to be

I'm setting up the following UIView animateWithDuration: method, with the intention of setting my animationOn BOOL elsewhere in the program to cancel that infinite looped repeat. I was under the impression that the completion block would be called each time a cycle of the animation ends, but this doesn't appear to be the case. Is the completion block ever called in a repeating animation? And if not, is there another way I can stop this animation from outside this method? - (void) animateFirst: (UIButton *) button { button.transform = CGAffineTransformMakeScale(1.1, 1.1); [UIView
