Question

我打算在我的iOS（Swift）应用程序中使用OAuth进行Facebook授权。但是知道大多数人都登录到Facebook iOS App而不是Safari（或Web浏览器），我希望在浏览器上显示Native App Authorization页面而不是同一页面，用户可能需要再次登录

我的网址是：http://zafaafh-dev.azurewebsites.net/login/facebook/

我也试过过URL Schemes。

FB URL Scheme：fb：//zafaafh-dev.azurewebsites.net/login/facebook/

它只是打开FB App但不是必需的授权页面。

您应该将您的应用添加到Facebook应用信息中心。然后按照本指南为您的应用添加Facebook身份验证Swift。根据文档更新您的Info.plist和AppDelegate.swift。 AppDelegate.swift看起来像这样：

Swift 3.0

import UIKit
import FacebookCore

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

        return SDKApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)
    }

    func applicationWillResignActive(_ application: UIApplication) {
        // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
        // Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.
    }

    func applicationDidEnterBackground(_ application: UIApplication) {
        // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
        // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
    }

    func applicationWillEnterForeground(_ application: UIApplication) {
        // Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
    }

    func applicationDidBecomeActive(_ application: UIApplication) {
        // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.

        AppEventsLogger.activate(application)
   }

    func applicationWillTerminate(_ application: UIApplication) {
        // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
    }

    public func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
        return SDKApplicationDelegate.shared.application(app, open: url, options: options)
    }

    public func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
        return SDKApplicationDelegate.shared.application(
        application,
        open: url as URL!,
        sourceApplication: sourceApplication,
        annotation: annotation
        )
    }
}
