Fixed the problem of "UITableview and tabbar overlapping"

gistfile1.m

- (void)loadView{
    // cannot set the height here because the data has not been loaded into the tableview yet
    // so I just set it to zero
    UITableView *tableView = [[UITableView alloc] initWithFrame:CGRectZero
                                                          style:UITableViewStylePlain];
}

// set the custom height here
- (void)viewWillLayoutSubviews{
    self.tableView.frame = CGRectMake(0, 0, [self widthForView], [self heightForView]);
}
