问题描述

隐藏或删除顶部的导航条

代码成功运行，但是在页面顶部多出来一个导航条，我想隐藏起来或者删除。

ClsMainPageAppDelegate.m

#import ""ClsMainPageAppDelegate.h""#import ""ClsTermsandConditionViewController.h""- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@""MainStoryboard"" bundle:nil];    ClsTermsandConditionViewController *ivc = [storyboard instantiateViewControllerWithIdentifier:@""termsandConditionControl""];    UINavigationController *navigationController=[[UINavigationController alloc] initWithRootViewController:ivc];    self.window.rootViewController=nil;    self.window.rootViewController = navigationController;    [self.window makeKeyAndVisible];}

解决方案

读一下文件说明： UINavigationController Class Reference

[navigationController setNavigationBarHidden:YES];

解决方案二：
在ClsTermsandConditionViewController.m文件的viewWillAppear 或 viewDidLoad中加入如下代码

-(void)viewWillAppear:(BOOL)animated {    [super viewWillAppear:animated];    [self.navigationController setNavigationBarHidden:YES];}
