iOS实战之导航栏

正文

#1、隐藏和显示导航栏 方法一：（简单粗暴）

- (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];
}

方法二：（使用代理）

//UINavigationControllerDelegate

- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated{ 
  BOOL isHiddenNavBar = [viewController isKindOfClass:[self class]]; 
  [self.navigationController setNavigationBarHidden:isVC animated:YES];
}
