使用wkwebview时，push后，再pop返回，报错
Cannot form weak reference to instance (xxxx) of class xxxx. It is possible that this object was over-released, or is in the process of deallocation
原因是给webView.scrollView设置了代理：webView.scrollView.delegate = self ；
解决办法：
-(void)dealloc
{
webView.scrollView.delegate = nil;
