Question

我有SDWebimage的最新版本，但它没有成功＆amp;失败我尝试了以下方法，但SDwebimage没有方法

[self.imageView setImageWithURL:[NSURL URLWithString:self.imageURL]
              placeholderImage:[UIImage imageNamed:@"YourPlaceholder.png"]
                       success:^(UIImage *image) {
                           // remove animation

                       }
                       failure:^(NSError *error) {
                           NSLog(@"thumbnail error: %@",error);
                           // handle failed download

                       }];

有人知道如何增加成功吗？ SDwebimage setImageWithURL中的失败阻止或任何其他替换如果从URL

Answer 1

试试这个：

[self.imageView setImageWithURL:[NSURL URLWithString:imageURL]
                   placeholderImage:[UIImage imageNamed:@"YourPlaceholder.png"]
                          completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType) {
                              //... completion code here ...
                          }];

Swift 3的解决方案：

cell.imageView?.sd_setImage(with: url) { (image, error, cache, urls) in
            if (error != nil) {
                //Failure code here
                cell.imageView.image = UIImage(named: "ico_placeholder")
            } else {
                //Success code here
                cell.imageView.image = image
            }
}

目标C的解决方案：

[cell.imageView sd_setImageWithURL:url
                  placeholderImage:nil
                         completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) {
                                if (error) {
                                  //Failure code here
                                  self.imageView.image = [UIImage imageNamed:@"ico_placeholder"];
                                } else {
                                  //Success code here
                                  self.imageView.image = image;
                                }
}];

希望你们觉得这很有用。

            imageView.sd_setImageWithURL(NSURL(string: urlString), completed: {
                (image, error, cacheType, url) in
                // do your custom logic here
            })

它有完成块

completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType)

你可以检查错误是否为零，然后一切都很好。
