我在iOS應用程序中創建了一些基本的動畫,它的表現完全正常......直到昨天。如何調試由UIKit的CoreAnimation調用觸發的崩潰?
我顯然做出了某種改變,以某種方式影響它,並且我很難確定問題是什麼。
當單步調試代碼,它得到這個塊的代碼,並且死步進在commitAnimation行之後(我最初寫這個之前,我認識的美女[UIView的animateWithDuration:...]:
UIView *favoritesTabItemView = [appDelegate.tabBarController.tabBar viewWithTag:0];
CGPoint startingPoint = [[magazineView superview]
convertPoint:CGPointMake(magazineView.center.x, magazineView.center.y) toView:appDelegate.window.rootViewController.view];
CGPoint targetPoint = CGPointMake(favoritesTabItemView.center.x - 214.0, favoritesTabItemView.center.y);
//shrink the icon down
UIGraphicsBeginImageContextWithOptions(magazineView.bounds.size, NO, 0.0);
[magazineView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
[UIImageView beginAnimations:nil context:nil];
[UIImageView setAnimationDuration:0.1];
PublicationCoverImageReflectionView.alpha = 0.0;
[UIImageView commitAnimations]; //<-- crash happens after this line
從後,我跨過commitAnimation調試器中的錯誤是給我什麼幫助?

有誰知道是什麼類型的數組這可能是說這是一個的UIKit調用,它的死亡時,所以我在想這個數組是一些vie的數組ws使用UIKit,但我沒有可見性...
任何想法如何解決甚至進一步調查這將是偉大的!
