在故事板中从初始化的UIViewController调用方法 - 目标c [英] Call method from initialized UIViewController in storyboarding - objective c

问题描述

我是目标c中的 Storyboarding 的新手，我需要从 UIVIewController 调用方法。在故事板之前我在 AppDelegate 中初始化 UIViewController 或者只是分配指针在那里，然后简单地从任何类调用方法，访问AppDelegate属性。怎么办故事板，如果没有 UIViewController 自己初始化？我的应用程序是 UITabBar 应用程序，如果它确实重要。

I'm new to Storyboarding in objective c and I need to call method from UIVIewController. Before Storyboarding I was initializing UIViewController in AppDelegate or just assigning pointer there, and then simply call method from any class, accessing AppDelegate properties. How to do It in Storyboarding, If there are no UIViewController initializing by myself? My app is UITabBar application if it does matter.

推荐答案

你可以从您的应用代表获取故事板的根视图控制器。例如：

You can get the root view controller of your storyboard from your app delegate. For example:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    UITabbarController *tbc = (UITabbarController *)self.window.rootViewController;

    // Do any setup you want to here
    // You aren't setting up the controller - just accessing the one that has been set up for you by the storyboard

    return YES;
}
