ios – UIWebview：WebThread EXC_BAD_ACCESS

我有一个完全简单的应用程序：使用 http://tv2.dk显示Web视图

我正在使用故事板,添加了Web视图并在我的控制器上设置了属性.为了简单起见,我没有设置代表.

在viewDidLoad中,我使用我想要加载的URL调用Web视图

[self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://tv2.dk"]]];

每次应用程序启动时,由于Web线程工作程序中的某些错误而导致崩溃,请参阅此转储.

我已经尝试在多个设备上运行此代码等,崩溃了.

解决方法

来自@RasmusStyrk上面的评论

I have found out that with using NSZombie’s,i got the following crash
message: WebviewCrash[4598:956679] *** -[UIViewAnimationState
release]: message sent to deallocated instance 0x1707c5370. To fix
this i had to turn off animations in UIVIew using [UIView
setAnimationsEnabled:NO]; and now it works. It seems like a bug in
iOS8. –

我们也有这个随机崩溃的地方,设置[UIView setAnimationsEnabled：NO]是唯一能够完全缓解这个问题的东西！
