ios開發之--首頁 導航欄隱藏 下一級頁面顯示，pop回來顯示白條

解決方法，在首頁中實現如下兩個方法，代碼如下：

-(void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
    [self.navigationController setNavigationBarHidden:NO animated:NO];
}

-(void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    [self.navigationController setNavigationBarHidden:YES animated:YES];
}

僅做記錄！
