Make UIImageView Flash - Animation Block - xcode

Question

I'm trying to make a UIImageView flash a few times when it collides with another in a small game I'm making.
I found THIS answer on this exchange and the answer that's been accepted as the best is this:
MyImage.alpha = 1.0f;
[UIView animateWithDuration:0.1f //speed of flash
delay:0.0f
options:UIViewAnimationOptionAutoreverse
animations:^ {
[UIView setAnimationRepeatCount:4.0f/2.0f]; //flash few times
MyImage.alpha = 0.0f;
} completion:^(BOOL finished) {
[MyImage removeFromSuperview];
}];
I also like edit 3's code on the 2nd answer down. However the above is the one I've been working with.
It works great but I'm having trouble having my UIImageView returning back to normal, after the flash has happened...
I've tried reseting the alpha value back to 1.0f in the completion block, and even at the end of the method I call to start the animation, but whatever I seem to be trying leaves the image invisible after the flashes... What am I missing? Thank you.
EDIT
I've also tried this way, and the image fades out and comes back, but it will only do it once :( I would like it to do it a few times:
-(void)AnimateComboFlash{ //call when collision occurs
for(int i = 1; i < 5; i++){
[self AltFlash];
}
}
-(void)AltFlash{
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.5f];
MyImage.alpha = 0.0f;
[UIView commitAnimations];
[self AltFlashBack];
}
-(void)AltFlashBack{
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.5f];
MyImage.alpha = 1.0f;
[UIView commitAnimations];
}

Answer 1

MyImage.alpha = 1.0f;
[UIView animateWithDuration:0.1f //speed of flash
delay:0.0f
options:UIViewAnimationOptionAutoreverse
animations:^ {
[UIView setAnimationRepeatCount:4.0f/2.0f]; //flash few times
MyImage.alpha = 0.0f;
} completion:^(BOOL finished) {
if (finished) {
[MyImage removeFromSuperview];
}
}];
You need to check if the animation is finished before you set the final value.

Answer 2

So after a long time reading through various questions and answers on this exchange about UIImageView animations, I finally found an answer HERE, by Enceradeira that worked for me, allowing the flash animation to happen, then the image to return to "normal" (with a full 1.0 alpha value).
Using his answer, and the code in my question, this is the method I used to make my UIImageView flash a few times, then return to it's original state:
MyImage.alpha = 1.0f;
[UIView animateWithDuration:0.1f //speed of flash
delay:0.0f
options:UIViewAnimationOptionAutoreverse
animations:^ {
[UIView setAnimationRepeatCount:4.0f/2.0f]; //flash few times
MyImage.alpha = 0.0f;
} completion:^(BOOL finished) {
//[MyImage removeFromSuperview]; //REMOVE THE REMOVE
MyImage.alpha = 1.0f; //RESET ALPHA VALUE AFTER COMPLETION
}];
Hopefully this will help some of you looking for similar answers.
