        Bg = [[BackGroundClass alloc]init];

        tableList = [[UITableView alloc] initWithFrame:CGRectZero style:UITableViewStylePlain];
        tableList.translatesAutoresizingMaskIntoConstraints = NO;
        tableList.dataSource=self;
        tableList.delegate=self;
        tableList.backgroundColor = [UIColor orangeColor];
        tableList.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
        tableList.separatorStyle = UITableViewCellSeparatorStyleNone;
        tableList.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];
        [tableList registerClass:[UITableViewCell class] forCellReuseIdentifier:@"Cell"];
        [mainView addSubview:tableList];
    }

    //UITableView Delegate Methods:-

    - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{

        return  10;
    }
    - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{

        return 1;
    }

    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

        static NSString *CellIdentifier = @"Cell";

        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier   forIndexPath:indexPath] ;

        if (cell == nil)
        {
            cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
        }
        cell.textLabel.text = @"hello";

        return cell;
    }

    -(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{

        return 50;
    }

    @end

You are setting the wrong frame for tableview. CGRectZero means that the table view is not visible on mainView . Update the below line

tableList = [[UITableView alloc] initWithFrame:CGRectZero style:UITableViewStylePlain];

with:-

tableList = [[UITableView alloc] initWithFrame:self.bounds style:UITableViewStylePlain];
