@H_502_22@解决方法 在第一个堆栈跟踪中,有以下代码：[UINavigationbar setTitleTextAttributes：]
它试图通过在标题上设置文本属性来自定义导航栏.你在做吗？你可以尝试评论一下,看看问题是否消失了？从技术上讲,你所拥有的不是内存泄漏.您正在访问已释放的对象.您可以做的另一件事是在您运行的方案上启用ZombIE Objects,并查看是否可以获取有关哪个对象已取消分配的信息.
现在,如果上面没有任何堆栈跟踪引导您直接编写任何代码,并且您说您已经使用了内存调试图工具并且没有找到任何对正在检查泄漏的对象的强引用,我会使用这里有一个更有创意的方法来找到问题.我经常使用的方法是消除.开始注释控制器的大部分,直到你只剩下空壳.每次,您都可以将代码缩减一半(日志性能),并重新测试代码的哪一部分引用已解除分配的对象.
显然,由于正常的应用程序 *** 作不会导致错误访问异常,它可能与XCode / Instruments内部相关,但上面的setTitleTextAttributes看起来很可疑,我首先会尝试缩小问题是否与导航栏相关.您是否对导航层次结构或导航栏UI的自定义做了一些奇怪的事情？
还要检查以前导航事件/实例在内存中是否存在同一个视图控制器的其他实例…这听起来像是一个UI对象被取消分配,然后由异步进程更新.
同样覆盖你的deinit {}.方法并在其中放置一个print语句,以检测所有被释放的相关对象.这将有助于缩小范围,以后将取消分配和访问哪个控制器.
它是出现在所有iOS版本/设备型号上还是仅出现在特定型号上？
