注：在iPad中，操作表的布局与iPhone不同，操作表不是从底部滑出的，而是随机的出现在触发它的按钮的周围，而且不能添加取消按钮，如果添加也不给予显示。

- (void)ActionSheetDemo{
    //操作表
    //UIAlertController 的枚举成员UIAlertControllerStyleActionSheet
    UIButton *buttonActionSheet = [[UIButton alloc] initWithFrame:CGRectMake(130, 300, 120, 45)];
    buttonActionSheet.backgroundColor = [UIColor grayColor];
    buttonActionSheet.layer.cornerRadius = 10;
    [buttonActionSheet setTitle:@"操作表" forState:UIControlStateNormal];
    [buttonActionSheet addTarget:self action:@selector(showActionSheetView:) forControlEvents:UIControlEventTouchUpInside];
    
    [self.view addSubview:buttonActionSheet];
    
    
}
- (void)showActionSheetView:(id)sender{
    NSLog(@"%s", __func__);
    
    //创建初始化
    UIAlertController *actionSheetController = [[UIAlertController alloc] init];
    
    //创建两个UIAlertAction(标题，样式，按钮动作相关的闭包)
    UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:^(UIAlertAction *action){
        NSLog(@"Tap cancel Button");
    }];
    UIAlertAction *destructiveAction = [UIAlertAction actionWithTitle:@"破坏性按钮" style:UIAlertActionStyleDestructive handler:^(UIAlertAction *action){
        NSLog(@"Tap 破坏性按钮 Button");
    }];
    UIAlertAction *otherAction = [UIAlertAction actionWithTitle:@"朋友圈" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action){
        NSLog(@"Tap 朋友圈 Button");
    }];
    
    //添加到控制器
    [actionSheetController addAction:cancelAction];
    [actionSheetController addAction:destructiveAction];
    [actionSheetController addAction:otherAction];
    
    //显示
    [self presentViewController:actionSheetController animated:TRUE completion:nil];
