Wrote a crossfade function but want to load images from array

[malaki1974]

This code works great crossfading 2 uiimageviews. I would like to use only the two uiimageviews but swap the content before they fade back in so I could have an unlimited amount (although for my purpose I am only going to be using 5-10). Any ideas on how to iterate through an array of images within this code?

-(void)crossFade {
	
	if (kenBurns1.alpha == 1.0) {
		kenBurns2.alpha = 1.0;
		UIViewAnimationOptions options = UIViewAnimationOptionAllowUserInteraction || UIViewAnimationOptionCurveEaseOut;
		[UIView animateWithDuration:0.5 delay:0.0 options:options 
						 animations:^{
								 
							 kenBurns1.alpha = 0.0;
						 }
						 completion:^(BOOL finished){
							 [kenBurns1 removeFromSuperview];
							 [self.view insertSubview:kenBurns1 atIndex:0];
						 }];
		
	} else if (kenBurns1.alpha == 0.0) {

		kenBurns1.alpha = 1.0;
		
		UIViewAnimationOptions options = UIViewAnimationOptionAllowUserInteraction || UIViewAnimationOptionCurveEaseOut;
		[UIView animateWithDuration:0.5 delay:0.0 options:options 
						 animations:^{
								
							 kenBurns2.alpha = 0.0;						 
						 }
						 completion:^(BOOL finished){
								 
							 [kenBurns2 removeFromSuperview];
							 [self.view insertSubview:kenBurns2 atIndex:0];

						 }];
	}
	
}

Just trying to bump it back into view

While bumping I took a fresh look again and might have solved it. I am sure it could be improved but...

kenburns1 is overtop of kenburns2. They switch z positions and get a new image and then fade - rinse and repeat. I will add scaling to fully recreate the kenburns effect but this is working for me.

-(void)crossFade {
	
	NSArray *imgArray = [NSArray arrayWithObjects:
						 [UIImage imageNamed:@"image4_large.png"], 
						 [UIImage imageNamed:@"image5_large.png"], 
						 [UIImage imageNamed:@"image9_large.png"],
						 [UIImage imageNamed:@"toc_gallery01.jpg"], 
						 [UIImage imageNamed:@"toc_gallery02.jpg"], 
						 nil];
	
	if (kenBurns1.alpha == 1.0) {
		
		kenBurns2.alpha = 1.0;
		UIViewAnimationOptions options = UIViewAnimationOptionAllowUserInteraction | UIViewAnimationOptionCurveEaseOut;
		[UIView animateWithDuration:1.0 delay:0.0 options:options 
						 animations:^{
							 kenBurns1.alpha = 0.0;
						 }
						 completion:^(BOOL finished){
							 [kenBurns1 removeFromSuperview];
							[self.view insertSubview:kenBurns1 atIndex:0];
							kenBurns1.image = [imgArray objectAtIndex:view1Index];
							 if (view1Index == 4) {
								 view1Index = 0;
							 } else {
								 view1Index++;
							 }
						 }];
		
	} else if (kenBurns1.alpha == 0.0) {

		kenBurns1.alpha = 1.0;
		
		UIViewAnimationOptions options = UIViewAnimationOptionAllowUserInteraction | UIViewAnimationOptionCurveEaseOut;
		[UIView animateWithDuration:1.0 delay:0.0 options:options 
						 animations:^{
							kenBurns2.alpha = 0.0;						 
						 }
						 completion:^(BOOL finished){
							[kenBurns2 removeFromSuperview];
							[self.view insertSubview:kenBurns2 atIndex:0];
							 kenBurns2.image = [imgArray objectAtIndex:view2Index];
							 if (view2Index == 4) {
								 view2Index = 0;
							 } else {
								 view2Index++;
							 }
						 }];
	}
}
