NSMutableArray *images = [[NSMutableArray alloc] init];
for (int i = 1; i < imageNames.count; i++) {
[images addObject:[UIImage imageNamed:[imageNames objectAtIndex:i]]];
}
// Normal Animation
UIImageView *animationImageView = [[UIImageView alloc] initWithFrame:CGRectMake(-6, 40, 200, 1034)];
animationImageView.animationImages = images;
animationImageView.animationDuration = 2;
animationImageView.animationRepeatCount = 0;
[self.view addSubview:animationImageView];
[animationImageView startAnimating];

Answer 1

If you know the animationRepeatCount before starting your animation
animationImageView.animationRepeatCount = 1 //For 1 loop
animationImageView.image = animationImageView.animationImages.lastObject;
For stoping animation dynamically
animationImageView.animationRepeatCount = 0 //infinite loop
When you need to stop the animation
[animationImageView stopAnimating];
animationImageView.image = animationImageView.animationImages.lastObject;

Answer 2

first set the animationRepeatCount to 1 and after starting the animation create a block that fires after the animation duration in this block set the animationImageView image to the last image .
dispatch_time_t dispatchAfter = dispatch_time(DISPATCH_TIME_NOW, animationImageView.animationDuration * NSEC_PER_SEC);
dispatch_after(dispatchAfter, dispatch_get_main_queue(), ^(void){
animationImageView.image = [images lastObject];
});

Answer 3

You could use transitionWithView:duration:options:animation:completion: of UIView for animating your UIImageView.
- (void)animatePictureTransition:(NSMutableArray *)arrayImages{
[UIView transitionWithView:imageViewButton
duration:1.0
options:UIViewAnimationOptionTransitionFlipFromRight
animations:^{
UIImage *newImage = (UIImage *)arrayImages.firstObject;
imageViewButton.image = newImage;
} completion:^(BOOL finished){
[arrayImages removeObjectAtIndex:0];
if(arrayImages.count) {
[self animatePicturesTransition:arrayImages];
}
}];
}
You could use this recursive, and call the method again inside the completion blog and pass through the remaining UIImages this way there shouldn't be a problem to stop at the last UIImages.
I would also recommend you, to load the UIImages dynamically from the resource folder in this way:
- (NSMutableArray *)getImagesWithSuffix:(NSString *)start andEndSuffix:(NSString *)end{
NSMutableArray *imageArray = [[NSMutableArray alloc] init];
for (int i = 1; i < 100; i++) {
NSString *fileName = [NSString stringWithFormat:#"%#%d%#.png", start, i, end];
if([self fileExistsInProject:fileName]){
[imageArray addObject:[UIImage imageNamed:fileName]];
} else {
break;
}
}
return imageArray;
}
Always writing all names of your UIImages takes a lot of time and can cause any problems. This way you just have to order your pictures so you can loop over.
To use this code, create a category of NSMutableArray and you can use it!

Answer 4

problem is with this line..
animationImageView.animationRepeatCount = 0;
by setting animationRepeatCount = 0 its set to infinite by default.
if u want it stop at last image you can go with
animationImageView.animationRepeatCount = 1; // specify no of times u need to run your animation.
