早上好，
我最近刚买了一台新的 iPad Air，我的应用程序由于某种原因不断崩溃，只在那个设备上。我对此有一种奇怪的感觉。它在 64 位模拟器上运行良好，我认为这是问题所在。我目前在 UITableView 单元格中使用 AsyncImageView https://github.com/nicklockwood/AsyncImageView 。这以前从未发生在我身上，但现在我不断得到：

它在这段代码中崩溃：
- (void)setImageURL:(NSURL *)imageURL
{
super.imageURL = imageURL;
if (_showActivityIndicator && !self.image && imageURL)

if (_activityView == nil)
{
_activityView = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:_activityIndicatorStyle];
_activityView.hidesWhenStopped = YES;
_activityView.center = CGPointMake(self.bounds.size.width / 2.0f, self.bounds.size.height / 2.0f);
_activityView.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleBottomMargin;
[self addSubview:_activityView];
}
[_activityView startAnimating];
}
