我的应用程序在闲置 5-7 分钟后在 XCode 中崩溃。我确定这与用于加载屏幕的动画有关 - 我粘贴了下面的代码。
我尝试启用 Zombie Objects 以查看它是否是对已释放对象的调用,并附上调试窗口崩溃时的屏幕截图。
顺便说一句 - 如果我按“恢复”,应用程序将继续正常运行..
编辑:这是第一次。我设置的全局断点在 [UIView animateWithDuration:0.2... 行停止,这是输出代码(这次硬崩溃了):

第二个动画的完成 block 递归调用 startAnimating。我认为这是问题的原因。您应该改用循环或创建重复动画。
关于iphone - UIAnimation 导致 XCode 在一段时间后崩溃,我们在Stack Overflow上找到一个类似的问题:
