UIAlertView和UIActionSheet相似,区别很小, 很容易理解。

    _actionSheet=[[UIActionSheet alloc]initWithFrame:CGRectMake(20, 20, 200, 100)];
    [_actionSheet addButtonWithTitle:@"相册"];
    [_actionSheet addButtonWithTitle:@"相机"];
    [_actionSheet addButtonWithTitle:@"取消"];
    _actionSheet.cancelButtonIndex=2;
    _actionSheet.destructiveButtonIndex=1;
    _actionSheet.title=@"提示";

    _actionSheet.delegate=self;
//    typedef NS_ENUM(NSInteger, UIActionSheetStyle) {

    _actionSheet.actionSheetStyle=UIActionSheetStyleBlackOpaque;
    _actionSheet.tag=10001;

    NSLog(@"firstOtherButtonIndex=%ld",_actionSheet.firstOtherButtonIndex);

        NSLog(@"i=%d %@",i,[_actionSheet buttonTitleAtIndex:i]);
    }
    [_actionSheet showInView:self.view];

}
//UIActionSheetDelegate
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
    if (actionSheet.tag==10001) {
        NSString *title=[_actionSheet buttonTitleAtIndex:buttonIndex];
        NSLog(@"我点击了: %@",title);
    }
    else
    {
        if (buttonIndex==2) {
            [_actionSheet dismissWithClickedButtonIndex:2 animated:YES];
        }
    }
}

//以下这些和UIAlertView的相似
- (void)actionSheetCancel:(UIActionSheet *)actionSheet
{
    NSLog(@"actionSheetCancel");
}

- (void)willPresentActionSheet:(UIActionSheet *)actionSheet
{
    NSLog(@"willPresentActionSheet");
}
- (void)didPresentActionSheet:(UIActionSheet *)actionSheet
{
    NSLog(@"didPresentActionSheet");
}

- (void)actionSheet:(UIActionSheet *)actionSheet willDismissWithButtonIndex:(NSInteger)buttonIndex
{
    NSLog(@"willDismissWithButtonIndex");
}
- (void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex
{
    NSLog(@"didDismissWithButtonIndex");
}
- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}
