ios - SDWebImage 动画图像

Question

我尝试了 100 多种使用 SDWebImage 制作图像动画的方法，但总是失败。我理解使用 block 好吗？我有 IBOutlet 属性图像名称 images1。我制作了数组来存储值并为 3 个图像制作动画。

  NSMutableArray *imagegallery = [[NSMutableArray alloc] init];

        NSLog(@"IMAGES-%@", imagegallery);


            [self.images1 setImageWithURL:[NSURL URLWithString:[self.objc objectForKey:@"Img1"]]
                         placeholderImage:[UIImage imageNamed:@"placeholder.png"]
                                completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType) {

                                    [imagegallery addObject:image];
                                    NSLog(@"Ima1-------%@", image);
                                }];
            [self.images1 setImageWithURL:[NSURL URLWithString:[self.objc objectForKey:@"Img2"]]
                         placeholderImage:[UIImage imageNamed:@"placeholder.png"]
                                completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType) {
                                    [imagegallery addObject:image];
                                }];
            [self.images1 setImageWithURL:[NSURL URLWithString:[self.objc objectForKey:@"Img3"]]
                         placeholderImage:[UIImage imageNamed:@"placeholder.png"]
                                completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType) {
                                    [imagegallery addObject:image];
                                }];

        self.images1.animationImages = imagegallery; //this line gets error
        self.images1.animationDuration = 0.5;
        [self.view addSubview:self.images1];
        [self.images1 startAnimating];

我想当你设置 self.images1.animationImages = imagegallery 因为你的图片还不能加载，method setImageWithURL:placeholderImage:completed: 是一个异步函数.你应该尝试另一种方式喜欢: Animate images in uiimageview
