UIAlertView的使用方法

// UIAlertView的常用方法

    // 标准样式

    UIAlertView *oneAlertView = [[UIAlertView alloc] initWithTitle:@"标题" message:@"提示内容" delegate:self cancelButtonTitle:@"关闭" otherButtonTitles:@"OK", nil];

    [oneAlertView show]; // 显示出来

    [oneAlertView release], oneAlertView = nil; // 释放内存

 

    oneAlertView.alertViewStyle = UIAlertViewStyleDefault; // 设置oneAlerView的样式

 

// 按钮横排显示

 

    UIAlertView *twoAlertView = [[UIAlertView alloc] initWithTitle:@"标题" message:@"提示内容" delegate:self cancelButtonTitle:@"关闭" otherButtonTitles:@"按钮1", @"按钮2",@"按钮2", nil];

    [twoAlertView show]; // 显示出来

    [twoAlertView release], twoAlertView = nil; // 释放内存

 

#pragma mark - 实现UIAlertView的代理方法判断按了哪个按钮

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

    // 获取您按下的是哪个按钮

    NSString* msg = [[NSString alloc] initWithFormat:@"您按下的第%d个按钮！",buttonIndex];

    NSLog(@"%@", msg);

    [msg release], msg = nil;

    // 点击“取消”，“按钮1”，“按钮2”，“按钮3”的索引buttonIndex分别是0，1，2，3

}

 

 

 

 

    // 给UIAlertView添加其他

    UIAlertView*alert = [[UIAlertView alloc]initWithTitle:@"请等待"

                                                  message:nil

                                                 delegate:nil

                                        cancelButtonTitle:nil

                                        otherButtonTitles:nil];

    [alert show];

    UIActivityIndicatorView *activeView = [[UIActivityIndicatorViewalloc]initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];

    activeView.center = CGPointMake(alert.bounds.size.width/2.0f, alert.bounds.size.height-40.0f);

    [activeView startAnimating];

    [alert addSubview:activeView];

    [activeView release];

    [alert release];
