SWRevealViewController - 手动切换到另一个视图？

Question

我有一个侧栏菜单,使用SWRevealViewController制作.

侧边栏中的一个菜单元素是"登录".它打开登录视图(通过自定义SWRevealViewController segue).

我想在用户成功登录后以编程方式切换到另一个视图.我该怎么做？

更新,我的代码:

ViewController *vc = [[ViewController alloc] init]; // this is main front ViewController
SWRevealViewController *revealController = self.revealViewController;
[revealController setFrontViewController:vc animated:YES];

在此之后,我得到空屏幕.我究竟做错了什么？我觉得这是错的:

ViewController *vc = [[ViewController alloc] init];

那么访问已加载的视图控制器的正确方法是什么？(它在应用程序启动时加载SWRevealViewController作为前端控制器)

Answer 1

试试这个:

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
SecondViewController *rootViewController = [storyboard instantiateViewControllerWithIdentifier:@"SecondViewController"];

UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:rootViewController];
[navController setViewControllers: @[rootViewController] animated: YES];

[self.revealViewController setFrontViewController:navController];
[self.revealViewController setFrontViewPosition: FrontViewPositionLeft animated: YES];

为我工作:-)

Answer 2

使用 - (void)setFrontViewController:(UIViewController *)frontViewController animated:(BOOL)animated;方法

SWRevealController有自己的属性,你可以从任何UIViewController访问:

SWRevealViewController *revealController = self.revealViewController;

您可以在它的GitHub存储库中检查示例项目:https: //github.com/John-Lluch/SWRevealViewController

Answer 3

这是setFrontViewController解决方案的Swift版本:

if let secondViewController = self.storyboard?.instantiateViewControllerWithIdentifier("SecondViewControllerStoryBoardID") as? SecondViewController {
  let navController = UINavigationController(rootViewController: secondViewController)
  navController.setViewControllers([secondViewController], animated:true)
  self.revealViewController().setFrontViewController(navController, animated: true)
} 

Answer 4

试试这个:

ViewController *vc = [[ViewController alloc] init]; // this is main front ViewController
UINavigationController* navController = (UINavigationController*)self.revealViewController.frontViewController;
[navController setViewControllers: @[vc] animated: YES];
// [navController pushViewController:vc animated:YES]; // use this if you want to stack the views
[self.revealViewController setFrontViewPosition: FrontViewPositionLeft animated: YES];

Answer 5

有一个新的API - (void)pushFrontViewController:(UIViewController *)frontViewController animated:(BOOL)animated;

据我所知,这是手动切换视图控制器之间正确动画的最优雅方式.

// get the view controller you want to push to properly.
// in this case, I get it from Main.storyboard
UIStoryboard *sb = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
UIViewController * vc = [sb instantiateViewControllerWithIdentifier:@"SignInViewController"];

UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:vc];

[navController setViewControllers: @[vc] animated:NO];
[self.revealViewController pushFrontViewController:navController animated:YES];

如果您在目标vc中不导入 SWRevealViewController并想要推回:

// get your vc properly
[self.navigationController setViewControllers:@[vc] animated:YES];

请注意,[self.navigationController showViewController:vc sender:self];结果相同,但不要使用它,因为这会在导航堆栈上创建一个新的视图控制器,这在使用时基本上没有意义SWRevealViewController.
