懒加载中用masonry定义wbwebview的布局,
在viewdidload中loadrequest,偶尔会crash,错误如下:
[Warning] Attempting to load the view of a view controller while it is deallocating is not allowed and may result in undefined behavior ()

断点定位在[MASViewConstraint setSecondViewAttribute]
抓耳挠腮头疼脑热之后才恍然大悟,在viedidload是,self.view有可能是nil,而此时让wkwebview去loadrequest会执行懒加载方法,masonry设定布局是找不到self.view必然就crash了.
解决办法:在viewwillappear中让wkwebview loadrequest
