尽量把所要调用的函数写成block形式的

示例如下，仅供参考：

//2.创建上传队列——————先取全部数据-----队列单笔上传操作---轮询分批复查————————count<0结束
-(void)createTackAllPsot{
    [self getAllTackDic];
    if (psotArr.count<1) {
        return;
    }
    dispatch_async(dispatch_get_global_queue(0, 0), ^{
    Context.isPosting = YES;
     dispatch_semaphore_t sema = dispatch_semaphore_create(0);
     dispatch_group_t group = dispatch_group_create();
        for (NSDictionary *postDic in psotArr){//创建上传队列
            [[SDKManager shareManager]initTimViewQueryData:@[postDic[@"bizGuid"]] WithResult:^(BOOL result, id resultString) {
                if (result == NO) {//检查是否有 ke上传的影像
                    dispatch_group_enter(group);
                    dispatch_async(dispatch_get_global_queue(0, 0), ^{
                        dispatch_semaphore_t sema2 = dispatch_semaphore_create(0);
                        //数据交易 上传

                        dispatch_semaphore_wait(sema2, DISPATCH_TIME_FOREVER);
                        dispatch_group_leave(group);
                    });
                }else{
                    dispatch_group_enter(group);
                    dispatch_async(dispatch_get_global_queue(0, 0), ^{

                                [newDic addEntriesFromDictionary:resultString];
                                [self yxkjPostTask:newDic withResultData:^(BOOL result, NSString *resultString) {
