ios导航栏隐藏和消失

框架XMNavShowOrHidden

导入头文件 #import "XMNav.h"

需要显示的控制器继承 XMShowNavViewController

需要隐藏的控制器继承 XMHiddenNavViewController

原理：在控制器父类添加

// 显示导航栏 #import "XMShowNavViewController.h"

-(void)viewWillAppear:(BOOL)animated{

[super viewWillAppear:animated];

self.navigationController.navigationBarHidden = NO;

NSLog(@"显示"); }

// 隐藏导航栏 #import "XMHiddenNavViewController.h"

-(void)viewWillAppear:(BOOL)animated{

[super viewWillAppear:animated];

self.navigationController.navigationBarHidden = YES;

NSLog(@"隐藏"); }
