未调用appdelegate中的clickedButtonAtIndex

Question

我在MyapplicationAppDelegate.m文件中用2个按钮"取消"和"确定"调用UIAlert,调用警报,但点击"取消"或"确定"按钮

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex

方法未被调用.

我在MyapplicationAppDelegate.h文件中添加了UIAlertViewDelegate,如下所示

#import UIKit/UIKit.h
@interface MyapplicationAppDelegate: NSObject UIApplicationDelegate,UIAlertViewDelegate
{
..
}

我想知道还需要什么.

Answer 1

在发布问题时我不确定它是否是您的拼写错误,但您应该在<..,..>中调用该委托

@interface MyapplicationAppDelegate: NSObject <UIApplicationDelegate,UIAlertViewDelegate> { .. }

以下是UIAlertView的示例代码

UIAlertView *myAlertView = [[UIAlertView alloc]initWithTitle:@""message:@"Your message goes here" delegate:self cancelButtonTitle:@"OK"otherButtonTitles:nil];
    [myAlertView show];
    [myAlertView release];

我不确定myAlertView.delgate = self是正确的方法,但我用initWithTitle设置委托
