Question

我尝试将动画图像设置为UILabel背景。我的标签从点（x = 0 y260到x = 480 y = 260）移动我想在动画期间添加UIImage。所以我试试这个

UIImageView *myimg=[[UIImageView alloc]init];
        myimg.animationImages =[NSArray arrayWithObjects:   
                                [UIImage imageNamed:@"1ANI.png"],
                                [UIImage imageNamed:@"2ANI.png"],
                                [UIImage imageNamed:@"3ANI.png"],nil];

        myimg.animationDuration = 1.5;
        myimg.animationRepeatCount = 0;
        [myimg startAnimating]; 
        [lbl1 addSubview:myimg];
        [myimg release];

我用单个UIImage设置UILabel背景像这样

UIImage *image=[UIImage imageNamed:@"1ANI.png"];
            lbl2.backgroundColor = [UIColor colorWithPatternImage:image];

单个图像代码可以工作，但是当我尝试使用Animates图像实现它时（如上面我的代码显示）那么它不起作用可以有人指导我如何将动画图像设置为UILabel Background.Thanx

试试这个

UILabel *label=[[UILabel alloc]initWithFrame:CGRectMake(10, 10, 100, 21)];
[label setText:@"asfsdf" ];
[label setBackgroundColor:[UIColor clearColor]];

UIImageView *imagView=[[UIImageView alloc]initWithFrame:CGRectMake(10, 10, 100, 21)];
imagView.animationImages =[NSArray arrayWithObjects:
                        [UIImage imageNamed:@"1ANI.png"],
                        [UIImage imageNamed:@"2ANI.png"],
                        [UIImage imageNamed:@"3ANI.png"],nil];

imagView.animationDuration = 1.5;
imagView.animationRepeatCount = 0;
[imagView startAnimating];
[self.view addSubview:imagView];
[self.view addSubview:label];

首先，不要将UIImageView添加到标签为[lbl1 addSubview:myimg];

的子视图

首先添加imageview，然后将uilabel添加到它上。您的标签将是透明的并浮动在uiimageview上。

您可能还需要[imageView setuserinteractionEnabled:YES];来查看uiimageview。

iOS 7中的这项工作

[myLabel setBackgroundColor：[UIColor colorWithPatternImage：[UIImage imageNamed：@“panel_dev_header”]]];
