Question

我尝试了100多种使用SDWebImage动画图像的方法，但总是失败。我对使用积木了解得好吗？我有IBOutlet属性图像名称images1。我创建数组来存储值并为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];

Answer 1

问题是imageGallery包含字符串以及您在已完成的块中添加的图像。由于您从不在imageGallery中使用这些字符串，所以没有理由将imageGallery设置为animae的副本。只需为imageGallery创建一个新的空可变数组。

Answer 2

我认为当您设置self.images1.animationImages = imagegallery因为您的图片尚未加载时，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
