How to pause and resume UIView Animation?

Question

I have a UIView with several UILabels that is animating from top to bottom and vice versa. A sort of Autoque let\'s say :) I use 2 functions:

-(void)goUp 
-(

Hope it will help you.

- (void)goUP{
    CFTimeInterval pausedTime = [self.layer timeOffset];
    self.layer.speed = 1.0;
    self.layer.timeOffset = 0.0;
    self.layer.beginTime = 0.0;
    CFTimeInterval timeSincePause = [self.layer convertTime:CACurrentMediaTime() fromLayer:nil] - pausedTime;
    self.layer.beginTime = timeSincePause;
}

- (void)goDown{
    CFTimeInterval pausedTime = [self.layer convertTime:CACurrentMediaTime() fromLayer:nil];
    self.layer.speed = 0.0;
    self.layer.timeOffset = pausedTime;
}

When you call the Layer animate, it will effect all layer tree and submode layer animate.
