如何删除ios中的导航栏？

Question

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


}

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

它是一个屏幕截图,当它向上转角时会略微显示.

我用这个代码隐藏了视图中的导航栏.但是当视图开始时它会给我效果,就像导航栏一样.

但是,我想删除此效果或仅删除此视图的导航栏.
