如何从内存中完全删除UIImageView动画？ [英] How do I remove an UIImageView animation from memory completely?

问题描述

我正在尝试释放我的应用程序内存，并希望在点击按钮时从内存中完全删除loadingImageView。我该怎么做？

I'm trying to free up my apps memory and want to completely remove loadingImageView from memory when I tap a button. How do I do this?

-(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?

}

谢谢！

推荐答案

好的。如果你想删除UIImageView动画，试试这个：

Ok. If you want to remove UIImageView animation try this:

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