當從一個頁面push 到下個頁面時,隐藏tabBar的方法:

如:DetailViewController

DetailViewController *detailVC =[[DetailViewController alloc] init];

  //在push之前先設定hidesBottomBarWhenPushed 為 YES,表示顯示tabBar;

    self.hidesBottomBarWhenPushed = YES;

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

    [detailVC release];

    //push之後,hidesBottomBarWhenPushed 設為NO,表示隐藏tabBar

    self.hidesBottomBarWhenPushed = NO;
