UIImageView animation starts and low memory warning occurs - ios

Question

I have an issue with my ImageView animation. In my view there are more than 10 views and each view have are identified from its tag value & I have UIImageView and UIButton. when a button is tapped then that particular image of the view have to be animated. If any other images are animated it have to be stopped. This is my code:
-(void)makeAnimation:(UIButton *)sender {
UIView *tagView=(UIView *)[self.view viewWithTag:sender.tag];
UIView *next=nil;
UIView *previous=nil;
NSLog(#"%d",sender.tag);
for (UIImageView * imageview in [tagView subviews]) {
if ([imageview isKindOfClass:[UIImageView class]]) {
if ([imageview isAnimating]) {
NSLog(#"Animation Happens");
}
else{
imageview.animationDuration=2.0;
imageview.animationImages=[animationArray objectAtIndex:sender.tag-1];
imageview.animationRepeatCount=2;
imageview.tag=sender.tag;
[imageview startAnimating];
}
}
}
next=(UIView*)[self.view viewWithTag:sender.tag+1];
previous=(UIView*)[self.view viewWithTag:sender.tag-1];
NSLog(#"NOT IDEA");
[self previousview:previous nextview:next];
}
-(void)previousview:(UIView *)previous nextview:(UIView*)next
{
for (UIImageView * imageview in [previous subviews]) {
if ([imageview isKindOfClass:[UIImageView class]]) {
[imageview stopAnimating];
NSLog(#"PRREVIOUS");
}
}
for (UIImageView * imageview in [next subviews]) {
if ([imageview isKindOfClass:[UIImageView class]]) {
[imageview stopAnimating];
NSLog(#"NEXT");
}
}
}
Now my issue is when I select more than 4 buttons one after another my app crashed with memory warning.

Answer 1

Find the exact location of leak using profile while running and use #autorelease{} to handle the memory manually
Like this..
-(void)makeAnimation:(UIButton *)sender {
#autorelease{
UIView *tagView=(UIView *)[self.view viewWithTag:sender.tag];
UIView *next=nil;
UIView *previous=nil;
NSLog(#"%d",sender.tag);
for (UIImageView * imageview in [tagView subviews]) {
if ([imageview isKindOfClass:[UIImageView class]]) {
if ([imageview isAnimating]) {
NSLog(#"Animation Happens");
}
else{
imageview.animationDuration=2.0;
imageview.animationImages=[animationArray objectAtIndex:sender.tag-1];
imageview.animationRepeatCount=2;
imageview.tag=sender.tag;
[imageview startAnimating];
}
}
}
next=(UIView*)[self.view viewWithTag:sender.tag+1];
previous=(UIView*)[self.view viewWithTag:sender.tag-1];
NSLog(#"NOT IDEA");
[self previousview:previous nextview:next];
}
}
