OptionViewController.swift:这是幻灯片菜单

override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

    var option : OptionVO
    option = viewOptions[indexPath.row]

    var nav = UIStoryboard.navigationController(option.identifier)!
    var detailController = nav.topViewController as DetailsViewController
    detailController.currentView = option.name
    self.revealViewController().revealToggleAnimated(true)
}
private extension UIStoryboard {
class func mainStoryboard() -> UIStoryboard { return UIStoryboard(name: "Main", bundle: NSBundle.mainBundle()) }

class func navigationController(identifier : NSString) -> UINavigationController? {
    return mainStoryboard().instantiateViewControllerWithIdentifier(identifier) as? UINavigationController
}

我有一个FrontViewController作为DetailsViewController.swift。
当我在幻灯片面板中选择一个不同的视图选项时,我只是执行了explainToggleAnimated(),它调出了FrontViewController。

现在,我想在DetailsViewController中为currentView变量使用此新视图集来更改屏幕

我想知道DetailsViewController完全显示后会收到什么回调,以便可以使用新设置的currentView变量。

仅供参考:
这些回调都不会被接收到:当调用exploringToggleAnimated()时,viewWillAppear,viewDidAppear,viewDidLoad都不会被接收。

解:
注册了SWRevealViewControllerDelegate:didMoveToPosition和调度通知:这是最终的代码片段

OptionViewController.swift [RearViewController]
override func viewDidLoad()
{
    self.revealViewController().delegate = self
}

override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

    var option : OptionVO
    option = viewOptions[indexPath.row]

    currentView = option.name
    self.revealViewController().revealToggleAnimated(true)//didMoveToPosition is called when reveal is finished
}

func revealController(revealController: SWRevealViewController!, didMoveToPosition position: FrontViewPosition)
{
    var notification = NSNotificationCenter.defaultCenter()

    if let myNextView: AnyObject = currentView {
        let viewDict = ["view" : myNextView]

        notification.postNotificationName("ShowFrontVC",
            object: nil,
            userInfo: viewDict)
    }
}

DetailsViewController.swift [FrontViewController]
func frontVCShown(notification:NSNotification)
{
    let userInfo:Dictionary<String,String!> = notification.userInfo as Dictionary<String,String!>
    currentView = userInfo["view"]
    //change the view for currentView
}

最佳答案

如果我正确理解了您的问题,建议您自己发送一个NSNotification。我将假设您正在为RearViewController使用tableView。

在您的RearViewController中

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    [[NSNotificationCenter defaultCenter] postNotificationName:@"ShowFrontVC" object:nil userInfo:nil];
}

在您的FrontViewController中
- (void)viewDidLoad {
    [super viewDidLoad];
    // Add observer
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(frontVCShown) name:@"ShowFrontVC" object:nil];
}

- (void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];
    // Remove Observer
    [[NSNotificationCenter defaultCenter] removeObserver:self];
}

- (void)frontVCShown {
    // Update your view controller
}

关于ios - SWRevealViewController:self.revealViewController()。revealToggleAnimated(true)时frontViewController上的回调是什么,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/30131992/
