我是iOS上的新手，我想在视图控制器上添加一个导航栏，并在左侧留有2个按钮，并在右侧进行订阅。香港专业教育学院不知道该怎么做。.直到现在，我刚刚从界面构建器中添加了一个导航栏，在.h文件中为其创建了一个（强烈）引用，并进行了以下编码。
navBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 20, 1026, 50)];
[navBar setTintColor:[UIColor clearColor]];
[navBar setBackgroundColor:[UIColor redColor]];
[navBar setDelegate:self];
[self.view addSubview:navBar];
UIBarButtonItem *bi1 = [[UIBarButtonItem alloc] initWithTitle:@"subscribe" style:UIBarButtonItemStyleBordered target:self action:@selector(editBotton)];
bi1.style = UIBarButtonItemStyleBordered;
bi1.tintColor =[UIColor colorWithWhite:0.305f alpha:0.0f];
self.navigationItem.rightBarButtonItem = bi1;
但没什么快乐..请帮助
您可以在AppDelegate中添加，
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone"
bundle: nil];
SampleViewController *mainViewController = (SampleViewController*)[mainStoryboard
instantiateViewControllerWithIdentifier: @"SampleViewController"];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:mainViewController];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[self.window setRootViewController:navigationController];
[self.window setBackgroundColor:[UIColor whiteColor]];
[self.window makeKeyAndVisible];
return YES;
}
