iphone - 我想在 UIImageView 上应用动画（通过 UIBuilder 创建）

Question

我已经添加了一个 UIView，在那个 UIImageView 上使用 UIBuider，现在我想在那个 imageView 上应用动画，所以我拍摄了一组图像并通过这段代码将该数组添加到 imageView

 NSArray *animationArray=[[NSArray alloc]init];
        animationArray=[NSArray arrayWithObjects:
                        [UIImage imageNamed:@"rabbit1.png"],
                        [UIImage imageNamed:@"rabbit2.png"],
                        [UIImage imageNamed:@"rabbit3.png"],
                        [UIImage imageNamed:@"rabbit4.png"],
                        [UIImage imageNamed:@"rabbit5.png"],
                        [UIImage imageNamed:@"rabbit6.png"],
                        [UIImage imageNamed:@"rabbit7.png"],
                        [UIImage imageNamed:@"rabbit8.png"],
                        [UIImage imageNamed:@"rabbit9.png"],
                        [UIImage imageNamed:@"rabbit10.png"],
                        [UIImage imageNamed:@"rabbit11.png"],
                        [UIImage imageNamed:@"rabbit12.png"],
                        [UIImage imageNamed:@"rabbit13.png"], nil];



        tempImageView.animationImages=animationArray;
        tempImageView.animationDuration=2;
        tempImageView.animationRepeatCount=0;
        [tempImageView startAnimating];

tempImageView 是使用 UIBuider 创建的，但它没有工作，没有显示任何内容。

故事板自动布局中似乎有一个错误..我发现同样没有结果..

通过代码尝试它，这有效..

mainImageView = [[UIImageView alloc]init];
    NSArray *animationArray = [[NSArray alloc]init];
    animationArray = [NSArray arrayWithObjects:[UIImage imageNamed:@"first.png"],[UIImage imageNamed:@"second.png"],[UIImage imageNamed:@"first.png"],[UIImage imageNamed:@"second.png"],[UIImage imageNamed:@"first.png"],[UIImage imageNamed:@"second.png"],[UIImage imageNamed:@"first.png"],[UIImage imageNamed:@"second.png"],[UIImage imageNamed:@"first.png"],[UIImage imageNamed:@"second.png"], nil]; //add your images here

    [mainImageView  setFrame:CGRectMake(50,50,100,100)];
    mainImageView.animationImages = animationArray; //mainImageView is   imageview
    mainImageView.animationDuration = 2;
    mainImageView.animationRepeatCount = 0;
    [mainImageView startAnimating];


      [self.view addSubview:mainImageView];
