首先，您应该了解有四种类型的崩溃，日志报告取决于崩溃的类型：

  1. 看门狗超时
  2. 用户强制/退出
  3. 内存不足
  4. 错误

    5. 日志报告分为以下几个部分：

答案 4 :(得分：1)

我遇到了同样的问题并发现了一个重复案例：当我浏览FlowCoverView中的图像并立即点击完成按钮时，它会崩溃并使用完全相同的崩溃日志。

看起来已完成的操作会导致FlowCoverViewController被释放，这会导致FlowCoverView的委托变为僵尸。

如果在此期间FlowCoverView的touchesEnded正在进行中，则会导致崩溃。

可能有更好的方法可以解决这个问题，但这是我尝试过的似乎解决了这个问题的方法：

在FlowCoverViewController的dealloc方法中，我尝试访问FlowCoverView以将其委托设置为nil：

-(void)dealloc
{
NSArray *viewsArray = [self.view subviews];
for (UIView*v in viewsArray)
{
if ([v isKindOfClass:[FlowCoverView class]])
{
FlowCoverView *fcv = (FlowCoverView*)v;
fcv.delegate = nil;
}
}
...
}

如果这解决了您的崩溃，请告诉我。
