问题描述
这个UIKit是因为标签从超级视图中被删除而崩溃的，所以我从发行版中得到这个崩溃日志，但是很难弄清楚这是什么意思而它正在被动画化？

解决方案
如果您正在删除在故事板或NIB中实例化的视图，请确保IBOutlet属性 strong 或 strong>而不是弱或分配，否则一旦从父视图中删除，它们就会被发布。
这是
@property（nonatomic，strong）IBOutlet UILabel * labelToRemove;
而不是
code> @property（nonatomic，weak）IBOutlet UILabel * labelToRemove;
I am getting this crash log from my release build but have a hard time figuring out what this means.
Is this UIKit crashing because the label got removed from superview while it was being animated?

解决方案
If you are removing views instantiated in Storyboard or NIBs, make sure the IBOutlet properties are strong or retain rather than weak or assign, otherwise they will be released as soon as they are removed from the parent view.
This is
@property (nonatomic, strong) IBOutlet UILabel* labelToRemove;
rather than
@property (nonatomic, weak) IBOutlet UILabel* labelToRemove;
