Question

我需要创建一个按钮（“继续”），打开另一个UiView / Page。我对发展很陌生。虽然有人可以请我走吧？谢谢你们，你们对我有很大的帮助。

代码：

- (IBAction)OpenActionSheetButton:(id)sender {


UIActionSheet *actionsheet = [[UIActionSheet alloc]initWithTitle:@"There is no going back,     are you sure???" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:@"Continue" otherButtonTitles:nil, nil];
[actionsheet showInView:self.view];
}

-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
if(buttonIndex == 0)
{
    UIViewController *controller =  [self.storyboard instantiateViewControllerWithIdentifier:@"storyboardViewIdentifier"];
    //storyboardViewIdentifier is the ViewController identifier you specify in the storyboard

    //PUSH
    [self.navigationController pushViewController:controller animated:YES];
    //Modal
    [self presentViewController:controller animated:YES completion:Nil];
}
}

这就是我对你的代码所做的：

- (IBAction)OpenActionSheetButton:(id)sender {


UIActionSheet *actionsheet = [[UIActionSheet alloc]initWithTitle:@"There is no going back, are you sure???" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:@"Continue" otherButtonTitles:nil, nil];
[actionsheet showInView:self.view];
}

-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
 if(buttonIndex == 0)
 {
    if(buttonIndex == 0)
        [self performSegueWithIdentifier:@"openView" sender:self];
    UIViewController *controller =  [self.storyboard


    instantiateViewControllerWithIdentifier:@"storyboardViewIdentifier"];
    //storyboardViewIdentifier is the ViewController identifier you specify in the storyboard

    //PUSH
    [self.navigationController pushViewController:controller animated:YES];
    //Modal
    [self presentViewController:controller animated:YES completion:Nil];
}

}

为什么不执行提示segue来启动下一个视图控制器？转到故事板并创建指向新视图控制器的segue。您需要创建一个模态segue并将其命名为独特的东西。

要执行此操作，请将所有必要的视图控制器添加到故事板，然后右键单击视图控制器演示。创建模态segue呈现。

然后从你的代码中你可以简单地把：

 if(buttonIndex == 0)
      [self performSegueWithIdentifier:@"openView" sender:self];

解雇更容易！

   [self dismissModalViewControllerAnimated:YES];

在故事板中使用UiActionSheet？
