从tableView跳转到另一个xib的方法

先把xib   id绑定好

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

CourseDetailViewController *CourseDetailVC = [[CourseDetailViewController alloc]initWithNibName:@"CourseDetailViewController" bundle:nil];

[self.navigationController pushViewController: CourseDetailVC animated:YES];

}
