Scrolling stops animations iOS

Question

My problem is quite simple, on my UIVIewController i have a custom UIView which is animated using CAAnimation and UIViewAnimation, i also have a UIScrollView, when the scrollView is scrolling the animated UIView stop all its animations !

timer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self 

selector:@selector(updateClock:) userInfo:nil repeats:YES];
hourHand.transform = CATransform3DMakeRotation (hourAngle+M_PI, 0, 0, 1);
...

In the Animated View i use : NSTimer, QuartzCore, and UIViewAnimation.

How can avoid this ? It is because i use a custom UIView ? (I'm still a beginner)

Thanks for all !

You may be interested in this SO question. UIScrollView scroll event blocks UIView animation

The proposed solution is to add the timer to the current loop.

[[NSRunLoop currentRunLoop] addTimer:timer forMode:NSRunLoopCommonModes];

it's ok just change NSDefaultRunLoopMode to NSRunLoopCommonModes – user2206906 Aug 09 '13 at 13:57
