如何让主界面NavigationBar隐藏,而push到的下一个界面显示NavigationBar?

- (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];}

注意，animated设为YES，仍是会有一个瞬间的过渡效果。只有设置为animated才能真正实现。

另外,把你的navagiatioincontroller的类型设置成不显示navigationbar的.
