Question

是的，我已经用Google搜索了这个问题并且我已经使用了确切的代码，但这仍然没有用。

这是我目前的Objective-C代码：

- (IBAction)btnTemp:(id)sender
{
    if (_deepSwitch.on == TRUE)
    {
        [self TempCleaner];
        _progress.progress += 1;
    }
    UIAlertView *cleaned = [[UIAlertView alloc] initWithTitle:@"Done!" message:@"Your device is now clean. Restarting SpringBoard." delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];

    [cleaned show];
}

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
    if (buttonIndex == [alertView cancelButtonIndex]) {
        NSLog(@"clicked");
    }
}

为什么这不起作用？我已尝试过buttonIndex 0，并取消按钮！

将提醒视图的委托设置为self

UIAlertView *cleaned = [[UIAlertView alloc] initWithTitle:@"Done!" message:@"Your device is now clean. Restarting SpringBoard." delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];

此外，请确保您提供警报视图的类声明UIAlertViewDelegate协议

//YourClass.h
@interface YourClass : SuperClass <UIAlertViewDelegate>

UIAlertView On按钮单击
