ios-隱藏或刪除頂部的導航條

隱藏或刪除頂部的導航條

代碼成功運行，但是在頁面頂部多出來一個導航條，我想隱藏起來或者刪除。

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];
}

最佳回答：

讀一下文件說明： UINavigationController Class Reference

[navigationController setNavigationBarHidden:YES];
