SWRevealViewController - RightViewController

Question

我正在使用SWRevealViewController 在我的应用程序中实现两个侧边导航视图。我按照故事板的方法，成功实现了后视图和前视图。我尝试通过情节提要设置与后视图完全相同的右视图，但无法做到。

我已将显示视图控制器 segue 设置为“sw_right”，但看起来它没有被 - (void)prepareForSegue:(SWRevealViewControllerSegue *)segue sender:(id)sender 识别，它为“sw_rear”和“sw_front”调用了两次

我错过了什么？

- (void)prepareForSegue:(SWRevealViewControllerSegue *)segue sender:(id)sender
{
// $ using a custom segue we can get access to the storyboard-loaded rear/front view controllers
// the trick is to define segues of type SWRevealViewControllerSegue on the storyboard
// connecting the SWRevealViewController to the desired front/rear controllers,
// and setting the identifiers to "sw_rear" and "sw_front"

// $ these segues are invoked manually in the loadView method if a storyboard
// was used to instantiate the SWRevealViewController

// $ none of this would be necessary if Apple exposed "relationship" segues for container view controllers.

NSString *identifier = segue.identifier;
if ( [segue isKindOfClass:[SWRevealViewControllerSegue class]] && sender == nil )
{
    if ( [identifier isEqualToString:SWSegueRearIdentifier] )
    {
        segue.performBlock = ^(SWRevealViewControllerSegue* rvc_segue, UIViewController* svc, UIViewController* dvc)
        {
            [self _setRearViewController:dvc animated:NO];
        };
    }
    else if ( [identifier isEqualToString:SWSegueFrontIdentifier] )
    {
        segue.performBlock = ^(SWRevealViewControllerSegue* rvc_segue, UIViewController* svc, UIViewController* dvc)
        {
            [self _setFrontViewController:dvc animated:NO];

        };
    }
    //This is never executed even after setting the identifier
    else if ( [identifier isEqualToString:SWSegueRightIdentifier] ) 
    {
        segue.performBlock = ^(SWRevealViewControllerSegue* rvc_segue, UIViewController* svc, UIViewController* dvc)
        {
            [self _setRightViewController:dvc animated:NO];
        };
    }
  }
}

这里是示例项目，我为你自己设计的很好，下载链接是

下载项目后你想删除项目，使用这个链接

这里你需要在前视图控制器上向右滑动，在特定视图控制器中添加UIBarButtonItem

    @property (strong, nonatomic) IBOutlet UIBarButtonItem *rightIcon;   //this is for left bar button Item
    @property (nonatomic) IBOutlet UIBarButtonItem* revealButtonItem;  //this is for right bar button Item

并添加一些功能是View DidLoad

- (void)viewDidLoad
{
[super viewDidLoad];

 //action for left Swipe
[self.revealButtonItem setTarget: self.revealViewController];
[self.revealButtonItem setAction: @selector( revealToggle: )];
[self.navigationController.navigationBar addGestureRecognizer:  self.revealViewController.panGestureRecognizer];

//action for Right Swipe
[self.rightIcon setTarget: self.revealViewController];
[self.rightIcon setAction: @selector( rightRevealToggle: )];
[self.navigationController.navigationBar addGestureRecognizer: self.revealViewController.panGestureRecognizer];
}

斯威夫特

override func viewDidLoad() {
super.viewDidLoad()
//action for left Swipe
self.revealButtonItem.target = self.revealViewController
self.revealButtonItem.action = "revealToggle:"
    self.navigationController.navigationBar.addGestureRecognizer(self.revealViewController.panGestureRecognizer)
//action for Right Swipe
self.rightIcon.target = self.revealViewController
self.rightIcon.action = "rightRevealToggle:"
    self.navigationController.navigationBar.addGestureRecognizer(self.revealViewController.panGestureRecognizer)
}

Answer 2

我发现了问题所在。在loadStoryboardControllers 方法[self performSegueWithIdentifier:SWSegueRightIdentifier sender:nil]; 被注释掉了。如果我们实现右视图控制器，则必须取消注释。

Answer 3

你要求我看这个帖子。

我没有故事板的经验。

所以，我将粘贴在我的项目中允许右侧的代码下方。 看看我评论的部分。希望这会让您走上正确的道路。

祝你好运

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:    (NSDictionary *)launchOptions
{
    UIWindow *window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    self.window = window;

    FrontViewController *frontViewController = [[FrontViewController alloc] init];
    RearViewController *rearViewController = [[RearViewController alloc] init];

    UINavigationController *frontNavigationController = [[UINavigationController alloc] initWithRootViewController:frontViewController];
    UINavigationController *rearNavigationController = [[UINavigationController alloc] initWithRootViewController:rearViewController];

    SWRevealViewController *revealController = [[SWRevealViewController alloc] initWithRearViewController:rearNavigationController     frontViewController:frontNavigationController];
    revealController.delegate = self;

// THIS SECTION RIGHT BELOW IS PROBABLY WHAT YOU WANT TO LOOK AT
    RightViewController *rightViewController = rightViewController =     [[RightViewController alloc] init];
    rightViewController.view.backgroundColor = [UIColor greenColor];

    revealController.rightViewController = rightViewController;

    revealController.bounceBackOnOverdraw=NO;
    revealController.stableDragOnOverdraw=YES;

    self.viewController = revealController;

    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];
    return YES;
}

Answer 4

在 SWRevealViewController.m 的 435 到 444 行之间有一个 try-catch 条件。只需将语句重新排列如下

        [self performSegueWithIdentifier:SWSegueRightIdentifier sender:nil];
        [self performSegueWithIdentifier:SWSegueFrontIdentifier sender:nil];
        [self performSegueWithIdentifier:SWSegueRearIdentifier sender:nil];

现在我的右菜单/右视图控制器正在工作，即使我没有使用左菜单/后视图控制器。

您也可以按照 shad 的建议进行操作。但是如果你得到一个正确的标志，你可以替换

- (void)loadStoryboardControllers


if ( self.storyboard && _rearViewController == nil )
{
    //Try each segue separately so it doesn't break prematurely if either Rear or Right views are not used.
    @try
    {
        [self performSegueWithIdentifier:SWSegueRearIdentifier sender:nil];
    }
    @catch(NSException *exception) {}

    @try
    {
        [self performSegueWithIdentifier:SWSegueFrontIdentifier sender:nil];
    }
    @catch(NSException *exception) {}

    @try
    {
        [self performSegueWithIdentifier:SWSegueRightIdentifier sender:nil];
    }
    @catch(NSException *exception) {}
}


}

与

 - (void)loadStoryboardControllers
{

//[self performSegueWithIdentifier:SWSegueRightIdentifier sender:nil];
[self performSegueWithIdentifier:SWSegueFrontIdentifier sender:nil];
[self performSegueWithIdentifier:SWSegueRearIdentifier sender:nil];

}

你可以看到我注释掉了

//[self performSegueWithIdentifier:SWSegueRightIdentifier sender:nil];

因为那是给您带来问题的人。如果是前面或后面，你也可以这样做
