(void)dealloc { [self.originImageView removeObserver:self forKeyPath:@"image"]; [self.originImageView removeObserver:self forKeyPath:@"contentMode"]; }

什么意思？ dealloc没有调用？你是ARC工程吗？

BMMax commented 8 years ago

pop后,程序蹦,提示没有销毁kvo,-(void)dealloc { [self.originImageView removeObserver:self forKeyPath:@"image"]; [self.originImageView removeObserver:self forKeyPath:@"contentMode"]; } 并没有调用.

应该不至于吧，我这么没有发现，找到原因了吗

An instance 0x15475ac00 of class UIImageView was deallocated while key value observers were still registered with it. Current observation info: <NSKeyValueObservationInfo 0x17085a340> ( <NSKeyValueObservance 0x1702d2440: Observer: 0x15475ac00, Key path: image, Options: <New: YES, Old: NO, Prior: NO> Context: 0x0, Property: 0x17024f9f0> )在keyWindow切换主控制器时,有几率发生. ImageView只有这里用了KVO. 是不是由于addObserver调用了2次导致,在多线程处理时?

这个应该不至于吧？这里没有用到多线程
