我有一个来自我们团队的老成员的新项目。不知道问题出在哪里...

  // Chooses the photo at the last index
    [group enumerateAssetsAtIndexes:[NSIndexSet indexSetWithIndex:[group numberOfAssets] - 1] options:0 usingBlock:^(ALAsset *alAsset, NSUInteger index, BOOL *innerStop) {

        // The end of the enumeration is signaled by asset == nil.
        if (alAsset) {
            ALAssetRepresentation *representation = [alAsset defaultRepresentation];
            [defaults setObject:representation.filename forKey:@"latest"];
        }
    }];
} failureBlock: ^(NSError *error) {
    // Typically you should handle an error more gracefully than this.
    NSLog(@"No groups");
}];

问题是，图书馆里没有照片……

对于我的问题，我添加了一些照片并解决了它！
