iphone - 单击警报 View 中的按钮时如何关闭警报 View

Question

我是 iOS 新手。

我正在研究警报 View 。这是我的代码。这里有 2 个警报 View :登录页面的 successfulallert 和 unsuccessfulallert。我在这里也使用alertview delegate，它适用于两个alertview，但我只想为成功的alertview工作，并且导航应该只为成功的alertview完成。如果有人知道这一点请帮助我。

NSString *responseOfResult = [[NSString alloc]initWithString:[result response]];
    NSRange match;
    //  NSLog(@"string= %@", str);
    match = [responseOfResult rangeOfString: @"successful"];
    if(match.location == NSNotFound)
    {
        UIAlertView *unsuccessfulAllert = [[UIAlertView alloc]
                               initWithTitle:@"Alert"
                               message:responseOfResult
                               delegate:self
                               cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
        [unsuccessfulAllert show];

    }
    else {
        UIAlertView *successfulAllert = [[UIAlertView alloc]
                               initWithTitle:@"Message" message:@"Login successful." delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
        [successfulAllert show];
     }
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
    if(buttonIndex == 0){
        [[self navigationController]pushViewController:registerUserScreen animated:YES];
    }
}

为什么不将“OK”作为cancelButtonTitle？一切都会自动处理。

UIAlertView *successfulAllert = [[UIAlertView alloc]
                               initWithTitle:@"Message" message:@"Login successful." delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
        [successfulAllert show];
