对于< FirstViewController:0x2a2c00>的开始/结束外观转换的不平衡调用。 [英] Unbalanced calls to begin/end appearance transitions for <FirstViewController: 0x2a2c00>
问题描述
我在模拟我的应用时遇到此问题,它不是错误或警告,但它出现在我的控制台中,有没有人曾经历过这个?
I have this problem when I simulate my app, its not an error or a warning but it appears in my console, has anyone ever experienced this before?
推荐答案
在我的情况下,当您非常快速地单击tableview中的两个选项卡时会发生此错误。
In my case, this error occurs when you click two tabs in a tableview very fast.
结果导致错误的titlename,后退按钮消失。有人提到当你推视图时,设置动画:否
。错误将消失但仍会导致一些奇怪的行为。它会推送两个视图,然后你需要返回两次才能返回tableview屏幕。
The result causes wrong titlename, back button disappear. Someone mentioned that when you push a view, set animated:NO
. The error will disappear but still causes some strange behavior. It pushes two views, then you need to back twice to get back the tableview screen.
方法我试图解决这个问题:
Method I tried in order to resolve this problem:
在 viewWillAppear中添加
BOOL cellSelected;
cellSelected = YES;
在didselectcell委托 if(cellSelected) {cellSelected = NO;做行动; }
in didselectcell delegate if (cellSelected){cellSelected = NO; do action ; }
这有助于防止非常快速地点击两个不同的单元格。
This helps prevent clicking two different cells very fast.
