通过Facebook应用程序而不是Web浏览器进行OAuth Facebook授权

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应用程序而不是Safari(或网络浏览器(，我希望显示本机应用程序授权页面，而不是浏览器上的同一页面，用户可能需要再次登录。

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

我也尝试过通过 URL 方案。

FB网址方案：fb://zafaafh-dev.azurewebsites.net/login/facebook/

它只是打开FB应用程序，而不是所需的授权页面。

您应该将您的应用程序添加到Facebook应用程序仪表板。然后按照本指南将 Facebook 身份验证添加到您的 Swift 应用程序中。根据文档更新您的Info.plist和AppDelegate.swift。 AppDelegate.swift 应如下所示：

斯威夫特 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
)
}
}
