UILable上如何添加背景圖片

//活動圖片

//創建一個Lable

    UILabel *activitylcon = [[UILabel alloc] initWithFrame:CGRectMake(10, 100, 80, 99)];

   

//添加背景爲圖案樣式

    activitylcon.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"tupian3.jpg"]];

//添加到視圖上

    [self.view addSubview:activitylcon];
