对不起,我已经缩小了错误,因此它不是AFNetworking问题,而是UI问题。尝试关闭iOS中的弹出窗口时出现异常
我有一个集合视图。当我点击集合视图时,会显示一个弹出窗口,我可以选择下载某个内容,然后进度条显示进度。同时,collectionviewcell还会在其自身上显示另一个进度条。然后我关上窗户,再次敲击牢房,做点什么然后关上它。它可能不会在第二次引发异常,并且当我再次打开并关闭popOver时,引发异常。
这里是LLDB的BT跟踪:

我不知道什么是错的通过查看跟踪。任何想法我的应用程序有什么问题?
编辑:
当我启用NSZombie,我看到这个错误在控制台:
*** -[BlurViewController performSelector:withObject:withObject:]: message sent to deallocated instance 0x166e7df0
的BlurViewController是一个视图控制器负责显示酥料饼的窗口。这是否意味着BlurViewController被释放? dismissDialog的
的源代码:
- (void)dismissDialog
{
[UIView animateWithDuration:kAnimationDuration animations:^{
self.view.alpha = 0.f;
self.popUp.transform = CGAffineTransformMakeScale(0, 0);
} completion:^(BOOL finished) {
[self removeFromParentViewController];
[self.view removeFromSuperview];
[self.popUp removeFromSuperview];
if (!self.popUp.isDownloading) {
_popUp = nil;
}
[UIView animateWithDuration:kAnimationDuration animations:^{
_blurView.alpha = 0.f;
} completion:^(BOOL finished) {
[_blurView removeFromSuperview];
}];
}];
}
请给你使用AFNetworking下载的代码。 – DilumN
您所指的某个对象已被释放。请张贴您的popover显示方法的代码。你也可以尝试运行NSZombies启用 – Paulw11
@ Paulw11在Xode中启用僵尸将会有所帮助,但是使用Instruments with Zombies setup会更好...可以查看所有refcount增量和减量以及哪些代码是负责任的,每个iOS都必须知道开发商 – RobP
