我想保留订单,因为用户可以在照片应用中重新排列他们的相册,所以我希望我的UI与列表顺序相匹配.

代码我用来设置列表：

PHFetchResult *smartAlbumFetchResult = [PHAssetCollection fetchAssetCollectionsWithType:
PHAssetCollectionTypeSmartAlbum subtype:PHAssetCollectionSubtypeAny options:nil];
 
PHFetchResult *albumFetchResult = [PHAssetCollection fetchAssetCollectionsWithType:
PHAssetCollectionTypeAlbum subtype:PHAssetCollectionSubtypeAny options:nil];
 
NSArray *collectionFetches = @[smartAlbumFetchResult,albumFetchResult];
 
NSMutableArray *albumArray = [NSMutableArray new];
 
for (PHFetchResult *newFetch in collectionFetches)
{
    for (PHAssetCollection *sub in newFetch)
    {
        [albumArray addObject:sub];
         // Other setup omitted
    }
}
