SWRevealViewController - 手動切換到另一個視圖？

Question

我有一個用SWRevealViewController製作的邊欄菜單。

邊欄中的菜單元素之一是「登錄」。它打開登錄視圖（通過自定義的SWRevealViewController segue）。

我想以編程方式切換到用戶成功登錄後的另一個視圖。我該怎麼做？

UPDATE，我的代碼：

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

這之後，我得到的只是空白屏幕。我究竟做錯了什麼？我覺得這是錯誤的：

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

那麼訪問已經加載的視圖控制器的正確方法是什麼？ （它由SWRevealViewController加載在應用程序啓動的前端控制器）

Answer 1

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

SWRevealController有它自己的屬性，你可以從任何UIViewController的訪問：

SWRevealViewController *revealController = self.revealViewController; 

您可以查看示例項目在它的GitHub repository： https://github.com/John-Lluch/SWRevealViewController

Answer 2

試試這個：

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 3

試試這個：

我

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]; 

工作:-)

Answer 4

有一個新的API - (void)pushFrontViewController:(UIViewController *)frontViewController animated:(BOOL)animated;

據我所知，這是正確的動畫最優雅的方式手動切換視圖控制器。

// 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]; 

如果您在目標VC不導入SWRevealViewController，想推回：

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

請注意，[self.navigationController showViewController:vc sender:self];有相同的結果，但不要用這個，因爲這在導航堆棧上創建一個新的視圖控制器，這在使用SWRevealViewController時基本沒有意義。

Answer 5

這一個對我的作品完美

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

UINavigationController *navController = [storyboard instantiateViewControllerWithIdentifier:@"NavController"]; 
[navController setViewControllers: @[rootViewController] animated: YES]; 

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

Answer 6

這裏是setFrontViewController解決方案的斯威夫特版本：

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 7

@Evana有一個很好的答案，但是我的情況，其參數傳遞到destViewController，我需要改進它如下。完全按照她的例子，我注意到DestViewController的viewDidLoad被調用了兩次。 'selectedId'首先爲0，只有第二次調用'selectedId'正在接收我的標籤值。

因此，爲了使清潔器導航，所述DestViewController必須從navController獲得，所以不存在冗餘呼叫。

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

UINavigationController *navController = [storyboard instantiateViewControllerWithIdentifier:@"DestNavController"]; 

DestViewController *destViewController = (DestViewController*)[[navController viewControllers] objectAtIndex:0]; 

destViewController.selectedId = ((UIButton*)sender).tag; 

[self.revealViewController setFrontViewController:navController];
