如何從內存中完全刪除UIImageView動畫？

Question

我正在嘗試釋放應用程序的內存，並希望在我點擊按鈕時從內存中完全刪除loadingImageView。 我該怎么做呢？

-(IBAction)animationOneStart { 

NSMutableArray *images = [[NSMutableArray alloc] initWithCapacity:88];

for(int count = 1; count <= 88; count++)
{
    NSString *fileName = [NSString stringWithFormat:@"testPic1_%03d.jpg", count];
    UIImage  *frame    = [UIImage imageNamed:fileName];
    [images addObject:frame];
}

loadingImageView.animationImages = images;

loadingImageView.animationDuration = 5;
loadingImageView.animationRepeatCount = 1; //Repeats indefinitely

[loadingImageView startAnimating];
[images release];

}

-(IBAction)removeFromMemory {

//What do I add here?

}

謝謝！

好。 如果要刪除UIImageView動畫，請嘗試以下操作：

-(IBAction)removeFromMemory {
    [loadingImageView stopAnimating];    //here animation stops
    [loadingImageView removeFromSuperview];    // here view removes from view hierarchy
    [loadingImageView release]; loadingImageView = nil;    //clean memory  
}

要從UIView實例中刪除CoreAnimation，請使用方法：

[view.layer removeAllAnimations];
