Get SPTImage from NSURL?

Question

我使用Spotify的新的iOS SDK测试版，不知道是否有一种方法来检索SPTImage从NSURL（最初是从提取SPTPartialAlbum.covers属性，或者只有这样，才能找回它是从获得SPTPartialAlbum第一？

Answer 1

I was able to accomplish this with the following code:

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
    NSError *error;
    NSData *imageData = [NSData dataWithContentsOfURL:URL options:0 error:&error];
    if (imageData) {
        dispatch_async(dispatch_get_main_queue(), ^{
            if (completion) completion([UIImage imageWithData:imageData]);
        });
    }
});
