ios之popToViewController : 'NSInternalInconsistencyException' , 原因 : 'Tried to pop to a view controller that doesn' t exist. '

我的 Secondview 是 BController *bview。
现在在这个 View 中有 1 个后退按钮

单击该后退按钮

-(IBAction)done:(id)sender 
{ 
AController *aview= [[AController alloc] initWithNibName:@"AController" bundle:[NSBundle mainBundle]]; 
 
    NSArray *array = [self.navigationController popToViewController: aview animated:YES]; 
 
} 

AController *aview 只是我的第一个 View ，或者你可以说第一个 View

但是在单击后退按钮时，我遇到了异常

** 由于未捕获的异常“NSInternalInconsistencyException”而终止应用程序，原因:“试图弹出到不存在的 View Controller 。”

在抛出“NSException”实例后调用终止

请您参考如下方法:

采用

[self.navigationController popViewControllerAnimated:YES]; 

或者

[self.navigationController popToViewController:[self.navigationController.viewControllers objectAtIndex:1] animated:YES];
