iOS开发：通过按下警报中的按钮Segue？ [英] iOS Dev: Segue by pressing a button in an Alert?

问题描述

我一直在搜索几个小时，没有找到任何答案，所以我非常感谢您的帮助！

I've been searching for a few hours and haven't found any answers, so I would really appreciate your help!

我正在设计一个应用程序，需要当按下警报中的按钮时，切换到不同的视图控制器。我已经设置了警报，但只需要代码来浏览一个新的视图。

I am designing an app and need to segue to a different view controller when a button in an alert is pressed. I already have the alert set up, but just need the code to segue to a new view.

推荐答案

尝试这个。先创建alertview。

Try this. create alertview first.

UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:@"Message"  message:@"Open New controller?" delegate:self cancelButtonTitle:@"No" otherButtonTitles:@"Yes",nil];
[alertView show];
[alertView release];

实施AlertView委托方法

Implement the AlertView Delegate Method

#pragma mark AlertView Delegate
-(void) alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
    if (buttonIndex != alertView.cancelButtonIndex)
    {
        Viewcontroller *vc = [[UIViewcontroller alloc] initWithNib:@"Viewcontroller"];
        [self presentModalViewController:vc];
        [vc release];
    }
}
