UIImageView change Background Color and setImage not working during Animation

Question

As the title said, it's very strange, did you agree?

So , if someone found your codes

imageView.backgroundColor = [UIColor greenColor]; 

or

imageView.image = [UIImage imageName:@"angryBird"];" 

are not working. Just mind that if your imageView is animating , or whether the animation has been removed or not.

－－－－－－－－－－The Answer Below－－－－－－－－－－－－－－－

Just stop animating before you set image and change background of the animating UIImageView.

UIImageView* imageView = [UIImageView alloc] init];
//......do sth. like setFrame ...
imageView.images = [NSArray arrayWithObjects....]; // set the animation images array 
imageView.animationDuration = 1.0;
[imageView startAnimating];
//......do sth.
[imageView stopAnimating];        // **** do not forget this!!!!! ****
imageView.backgroundColor = [UIColor greenColor];
imageView.image = [UIImage imageName:@"angryBird"];

When you performSelector: withObject: afterDey:1.0s , in the selector method , also, you need to stopAnimating too, and then setImage or change background color.

Answer 1

Try to change background color and changing the image once animation is complete. it will simply work for you.

Answer 2

Try this:

[UIView animateWithDuration:1.0 animations:^(){} completion:^(BOOL finished){}];
