    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil message:@"An Alert!" 
                                                   delegate:self cancelButtonTitle:@"OK" otherButtonTitles:[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://phobos.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=301349397&amp;amp;amp;amp;mt=8"]];];
    [alert show];
    [alert release];

我正在尝试显示一个带有一个“确定”按钮和一个“购买完整版本”按钮的 UIAlertView。我怎样才能使上面的代码工作？

谢谢

您需要处理 UIAlertViewDelegate。

另外，otherButtonTitles 只是用作标题的 NSString 对象的 va_list，您可以设置在 UIAlertViewDelegate< 中点击它们时会发生什么。 /code> 的 alertView:clickedButtonAtIndex: 方法：

- (void) alertView:(UIAlertView *) alertView clickedButtonAtIndex:(NSInteger) index {
    if(index == 1) {
       [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://phobos.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=301349397&amp;amp;amp;mt=8"]];
    }
}

不要忘记设置 delegate：

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil message:@"An Alert!" 
                                                            delegate:self
                                                   cancelButtonTitle:@"OK"
                                                   otherButtonTitles:@"Buy Full Version"];
[alert show];
[alert release];

You need to handle the button click in the UIAlertViewDelegate that you specify.

Also, otherButtonTitles is simply a va_list of NSString objects to use as titles, you set what happens when they are tapped in UIAlertViewDelegate's alertView:clickedButtonAtIndex: method:

- (void) alertView:(UIAlertView *) alertView clickedButtonAtIndex:(NSInteger) index {
    if(index == 1) {
       [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://phobos.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=301349397&amp;amp;amp;mt=8"]];
    }
}

Don't forget to set the delegate:

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil message:@"An Alert!" 
                                                            delegate:self
                                                   cancelButtonTitle:@"OK"
                                                   otherButtonTitles:@"Buy Full Version"];
[alert show];
[alert release];
