Question

我正在尝试在iOS swift应用程序中使用Facebook来获取一些基本的用户信息。我使用Cocoapods来安装Facebook依赖项。我使用以下链接更新了我的info.plist。

https://developers.facebook.com/docs/ios/ios9 https://developers.facebook.com/quickstarts/115956755431487/?platform=ios

每当我尝试通过facebook登录时，都会收到以下编译器错误：

package cyanlauncher;

import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.geometry.Insets;
import javafx.stage.Stage;
import javafx.stage.StageStyle;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.HBox;
import javafx.scene.layout.Pane;


public class Main extends Application {
    private int numApps = 0;
    private float btnSize = 48;
    private float btnSpacing = 12;
    @Override
    public void start(Stage primaryStage) {
            primaryStage.initStyle(StageStyle.TRANSPARENT);
            primaryStage.setTitle("CyanLauncher");

            Button quitBtn = new Button();

            Pane  root = new Pane();
            root.getChildren().add(addHBox());

            quitBtn.setGraphic(new ImageView(new Image(getClass().getResourceAsStream("./../data/exit.png"))));
            quitBtn.setLayoutX(10 + ((btnSize + btnSpacing) * numApps));
            quitBtn.setLayoutY(7);
            quitBtn.setPadding(new Insets(0,0,0,0));
            quitBtn.setPrefSize(btnSize, btnSize);
            quitBtn.setOnAction(new EventHandler<ActionEvent>(){

                @Override
                public void handle(ActionEvent event){
                    System.exit(0);
                }

            });

            root.getChildren().add(quitBtn);


            Scene scene = new Scene(root,64,64);


            scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());
            scene.setFill(null);

            primaryStage.setScene(scene);
            primaryStage.show();
    }

    public HBox addHBox() {
        HBox hbox = new HBox();
        hbox.setPrefSize(64, 64);
        hbox.setLayoutX(10);
        hbox.setLayoutY(7);  
        return hbox;
    }

    public static void main(String[] args) {
        launch(args);
    }
}

其他信息：Swift 2，Xcode 7，iOS 9

如果您有任何建议可以解决此问题。

我的错误是我的AppDelegate中有以下两个功能。不推荐使用sourceApplication的openURL方法，因此应用程序将使用更新的方法。但是，Facebook自己的文档声明使用已弃用的版本导致我的错误位于此处：https://developers.facebook.com/docs/ios/getting-started

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool {
        return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)
}

func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {
}

Facebook声明要使用不推荐的openURL http://imgur.com/kwI5VId
