升级xcode9后，发现导航栏隐藏在tabbar切换时有明显的快速闪动效果，有动态隐藏的效果，看着不舒服。

代码如下：

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

解决方案
设置animated的时候不要直接设为YES，改成上面这样就可以解决tabbar切换时导航栏快速闪的问题。

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