To find any object in a view

here I am searching for a button in a AlertView.


for (UIView *v in [myAlertView subviews]) {
if ([v isKindOfClass:[UIButton class]]) {
//IF I AM THE RIGHT BUTTON
[v addSubview:myUIImageView];
}
}

Animation: Move an object

Show something moving across the screen. Note: this type of animation is "fire and forget" -- you cannot obtain any information about the objects during animation (such as current position). If you need this information, you will want to animate manually using a Timer and adjusting the x&y coordinates as necessary.



CABasicAnimation *theAnimation; theAnimation=[CABasicAnimation animationWithKeyPath:@"transform.translation.x"]; theAnimation.duration=1; theAnimation.repeatCount=2; theAnimation.autoreverses=YES; theAnimation.fromValue=[NSNumber numberWithFloat:0]; theAnimation.toValue=[NSNumber numberWithFloat:-60]; [view.layer addAnimation:theAnimation forKey:@"animateLayer"];
