我有两个UIViewController
课程,其中FirstClass
我有一个UIButton
for Login,当用户点击按钮时,我将显示SecondClass
......为此我已经完成了,
SecondClass *index = [[SecondClass alloc] init];
[self presentModalViewController:index animated:YES];
在 SecondClass 我有一个注销按钮,它将重定向到FirstClass,因为我已经完成了,
[self dismissModalViewControllerAnimated:YES];
当我在 SecondClass 中按下注销按钮时,我收到警告消息
**Attempt to dismiss from view controller <FirstClass: 0e39w88e160> while a presentation or dismiss is in progress!**
这里有什么问题..
