我写的是一朋友圈的功能，需要显示状态的点赞数和评论数，但是点赞和评论的接口都是 block异步获取，在格式化 model的时候无法正常获取，所以想请求解决方法，非常感谢。
-(HxAlbumModel *)factoryModel:(BmobObject *)obj statusType:(StatusType)type{
hxAlbum *albumOBj = [[hxAlbum alloc] initFromBmobObject:obj];
NSMutableArray* photos=[NSMutableArray array];
NSArray * albumPhotos = [obj objectForKey:@"albumPhotos"];
if (albumPhotos.count !=0) {
for(NSString * photoUrl in albumPhotos){
hxAlbumPhoto *photo = [hxAlbumPhoto photoWithOriginUrl:photoUrl thumbnailUrl:[NSString stringWithFormat:@"%@!/format/png",photoUrl]];
[photos addObject:photo];
}
}
//这里格式化 model数据，其中的commentArray和digArray 需要从 block块内异步获取的，这里我就不知道如何操作比较好，所以想问问。非常感谢。
HxAlbumModel*model = [HxAlbumModel hxAlbuMmodelWithType:Status_ENUM_TYPE fromUser:albumOBj.creator bmobOject:albumOBj avatar:[albumOBj.creator objectForKey:KEY_AVATAR] time:[albumOBj.createdAt stringWithFormat:@"MM-dd HH:mm"] statusID:albumOBj.objectId statusCreateAt:[NSString stringWithFormat:@"%.3lf",[albumOBj.createdAt timeIntervalSince1970]] digArray:albumOBj.toDigs commentArray:albumOBj.toStatusComments contentText:albumOBj.timeline photosArray:photos statusContentRelatedType:nil];
return model;
}
//查询点赞的关联表
- (void)queryDigsRelation:(NSString*)statusID toDigs:(void(^)(NSMutableArray * toDigs))sucessed{
//关联对象表
BmobQuery *bquery = [BmobQuery queryWithClassName:@"_User"];
//需要查询的列
BmobObject *post = [BmobObject objectWithoutDataWithClassName:@"hxAlbum" objectId:statusID];
[bquery whereObjectKey:@"toDigs" relatedTo:post];
[bquery findObjectsInBackgroundWithBlock:^(NSArray *array, NSError *error) {
if (error) {
NSLog(@"%@",error);
}else{
[array enumerateObjectsUsingBlock:^(id _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
BmobObject *user = obj;
NSLog(@"===%@",[user objectForKey:@"username"]);
}];
sucessed([array copy]);
}
}];
}

这是用这异步函数进行尝试编写的，但是我感觉有些地方还需要优化一下。麻烦大佬看下，看看是不是这样搞的，非常感谢。🙏
