iOS导航栏切换界面时隐藏和显示 解决闪烁

- (void)viewWillAppear:(BOOL)animated {

[superviewWillAppear:animated];

[self.navigationControllersetNavigationBarHidden:YESanimated:animated];

}

- (void)viewWillDisappear:(BOOL)animated {

[superviewWillDisappear:animated];

[self.navigationControllersetNavigationBarHidden:NOanimated:animated];

}

设置animated的时候不要直接设为YES，改成上面这样就可以解决楼主说的快速闪的问题。
