UIView Animation not working - iOS - ios

Question

I am trying to animate a simple UIImageView, but it is not working. Here is my code:
In my header file, I have declared "light_bulb" as a UIImageView.
NSMutableArray *bulb_off_images = [[NSMutableArray alloc] init];
for (int loop = 0; loop < 11; loop++) {
if (loop >= 10) {
[bulb_off_images addObject:[UIImage imageNamed:[NSString stringWithFormat:#"bulb_off-%d.png", loop]]];
}
else {
[bulb_off_images addObject:[UIImage imageNamed:[NSString stringWithFormat:#"bulb_off-0%d.png", loop]]];
}
}
[UIView animateWithDuration:0.5 delay:2.0 options:UIViewAnimationOptionCurveEaseInOut animations:^{
light_bulb.animationImages = bulb_off_images;
} completion:^(BOOL finished){
if (finished) {
NSLog(#"Finished !!!!!");
}
}];
The code seems to run and the completion block is called but the animation does not happen.....
**Update 1 **
I tried doing the animation this way, but I need a way of stopping the animation from repeating itself. How do I know when to call "stopAnimating". Here is my code:
light_bulb.animationImages = bulb_off_images;
light_bulb.animationDuration = 0.5;
light_bulb.animationRepeatCount = 0;
[light_bulb startAnimating];
What am I doing wrong?

Answer 1

In regards to your original question, you're over-complicating your solution. UIImageView has animation methods built-in. It looks like you're trying to use them in conjunction with UIView's animation features, which won't work exactly the way you're planning. Review the docs for each, and decide which classes' animation features you would like to use.
(For images, UIImageView's animation methods seem to be the preferred way to go.)
As for your second question: in the documentation for UIImageView, the notes for animationRepeatCount state:
The default value is 0, which specifies to repeat the animation indefinitely.
Setting your animationRepeatCount to 1 should play the animation only once.
