- (void)viewWillAppear:(BOOL)animated
{
[self.navigationController setNavigationBarHidden:YES animated:YES];
[super viewWillAppear:animated];
}
-(void)viewWillDisappear:(BOOL)animated{
[self.navigationController setNavigationBarHidden:NO animated:YES];
[super viewWillDisappear:animated];
}
这样写有个问题，如果首页没有导航条，下一页有，切换tabbar的时候，这一页会有隐藏导航条的动画
所以
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
if (self.tabBarController.selectedIndex != 0) {
[self.navigationController setNavigationBarHidden:YES animated:NO];
}else{
[self.navigationController setNavigationBarHidden:YES animated:YES];
}
}
-(void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
[self.navigationController setNavigationBarHidden:NO animated:YES];
}
应该加个判断
