问题描述
我在下面使用代码,但未加载:
I use code below, but it is not loaded:
UIStoryboard * storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
self.mapViewController = [storyboard instantiateViewControllerWithIdentifier:@"MapViewController"];
self.navigationController = [[UINavigationController alloc]initWithRootViewController:self];
self.navigationBar = [[UINavigationBar alloc]init];
[self.view addSubview:self.navigationBar];
[self.navigationController.navigationController pushViewController:self.mapViewController animated:YES];
推荐答案
尝试如下
UIViewController *bbp=[[UIViewController alloc]initWithNibName:@"UIViewController" bundle:nil];
UINavigationController *passcodeNavigationController = [[UINavigationController alloc] initWithRootViewController:bbp];
// [self.navigationController presentModalViewController:passcodeNavigationController animated:YES];
[self.navigationController pushViewController:passcodeNavigationController animated:YES];
[passcodeNavigationController release];
