Warning: Attempt to present <...> on <…> which is already presenting null
这个警告碰上的几率比较低,但还是会碰上的.
我看了许多关于的这个问题的博客都没有一个具体说明的原因.
说说我怎么触发的.
在一个controller里面先是present了一个控制器,然后经过一段业务.....................然后present另外一个控制器,dismiss之前的控制器,成功触发,但也有几率的.
就是说主线程在present和dismiss有所冲突.就是在dismiss的时候把刚present的控制器也dismiss了.
解决
dismiss之后再present
