我正在使用以下代码从服务器下载一些图片,
-(void)viewDidLoad
{
for (int i = 0 ; i < picsNames.count ; i++) {
UIImageView *imageView = [[UIImageView alloc] initWithFrame: CGRectMake(i * 320.0, 0.0, 320.0, self.view.frame.size.height)];
imageView.backgroundColor = [UIColor blackColor];
imageView.tag = IMAGE_VIEWS_TAG + i;
[scrollView addSubview:imageView];
//getting the image
NSInvocationOperation *operation = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(getImage:) object:imageView];
[queue addOperation:operation];
}
}
-(void)getImage:(UIImageView *)imageView
{
//getting the "image" from the server .....
[self performSelectorOnMainThread:@selector(loadPic:) withObject:[NSArray arrayWithObjects:imageView, image,nil] waitUntilDone:YES];
}
-(void)loadPic:(NSArray *)imageAndImageViewArray
{
//loading the image to imageview
UIImageView *imageView = (UIImageView *)[imageAndImageViewArray objectAtIndex:0];
imageView.image = (UIImage *)[imageAndImageViewArray objectAtIndex:1];
}
加载一些图片后,以下行会显示内存警告并导致应用崩溃。
[self performSelectorOnMainThread:@selector(loadPic:) withObject:[NSArray arrayWithObjects:imageView, image,nil] waitUntilDone:YES];
我不知道如何解决这个问题。 谢谢大家:)
答案 0 :(得分:0)
因此,在花了太多时间之后,我意识到错误是由于太多的UIImage对象分配同时没有主NSTread的NSQueue。
所以只需更改为代码,这样我当时只有10个UIImage对象。
