ios - 8.4 上的警报 View 未关闭

Question

场景
1)我开始编辑键盘来了。
2)然后我触摸一个按钮
3)在触摸按钮时我添加了AlertView，在添加之前我已经辞去了第一响应者
4)点击 AlertView OK 按钮我弹出 viewController
5)弹出后，keyBoard 会在该屏幕上出现一段时间，然后关闭。
6)它应该在同一个 Controller 上而不是在前一个 Controller 上被解雇

代码-

- (IBAction)cancelSkipButtonTouchUpInside:(id)sender {

  [self.textMobileNumber resignFirstResponder];
    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:nil message:@"Entered number will not be saved" delegate:self cancelButtonTitle:nil otherButtonTitles: @"OK",@"Cancel", nil];
    alertView.tag = ktagYourNumberWillNotBeSaved;
    [alertView show];
    alertView = nil ;

}


- (void) alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
case ktagYourNumberWillNotBeSaved:
   {
    [self.navigationController popToViewController:self animated:YES];
     }      
 }

Answer 1

在这里你添加了 self 这意味着你的导航堆栈调用相同的 ViewController，请尽量避免选择 1 和 2

改变

 [self.navigationController popToViewController:self animated:YES];

进入

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

else 选择 2

 for (UIViewController *vc in self.navigationController.viewControllers) {
   if ([vc isKindOfClass:[ViewController2 class]]) // ViewController2 --> call your view controller where you want to pop
 {
    [self.navigationController popToViewController:vc animated:YES];
}
}

else choice-3

[self.navigationController popViewControllerAnimated:YES]
