Warning: Attempt to dismiss from view controller <SetUpViewController: 0x15bd67f0> while a presentation or dismiss is in progress!，有需要的朋友可以参考下。

Ios:在你使用presentModalViewController加载过多的视图过程中，退出当前视图selfdismissViewControllerAnimated:YEScompletion:nil] ;或者 selfdismissViewControllerAnimated:NOcompletion:nil];使用如果遇到报这样的警告且返回不到上个视图，可以参考参考我下边的解决方案：

如果使用

if (![self.presentedViewController isBeingDismissed]) {

[self dismissViewControllerAnimated:YES completion:nil];

}

没有效果的情况下说明：您的当前视图在主线程还没有加载出来,所以是释放不了当前视图的，您可能需要使用如下代码

[objc] view plain copy

1. dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.2 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{  
2.             [self dismissViewControllerAnimated:NO completion:nil];  
3.          });  

这样做的好处是让主线程等待0.2秒再退出视图, 就可以退出了!
