UIAlertView的基本操作

UIAlertView 提示框

 

定义并显示：

 

UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"title" message:nil delegate:nil
 cancelButtonTitle:@"button" otherButtonTitles: @"otherButton",nil];
[alert show];
[alert release];

 

多个按钮可对otherButtonTitles进行设置 例如：otherButtonTitles: @"otherButtonOne",@"otherButtonTwo"，nil

 

当多个按钮是判断按下了哪个按钮，首先要遵守 UIAlertViewDelegate 协议

 

重写方法：

 

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
     if(buttonIndex == 0){
        NSLog(@"The First Button Pressed");          
    }else if(buttonIndex == 1){
        NSLog(@"The Second Button Pressed");      
   }else{
.....
}

 判断buttonIndex的值即可。
