我正在使用最新的 FBSDKLoginKit (4.10.1) 让我的用户通过 Facebook 进行身份验证。它在 iOS 9 上完美运行，但在 iOS 8 上运行不佳。当用户进行身份验证时，应用程序切换到 native facebook 应用程序或 safari 以登录。登录后，应用程序切换回我的应用程序，但随后没有任何反应。处理程序 block 未执行。完全相同的代码适用于 iOS 9，但不适用于 8。我注意到当我的应用程序切换到 safari 进行身份验证时，xcode 的调试器与模拟器分离；所以我无法发现任何错误。这不会发生在 iOS 9 上。
这是我的登录代码:
@IBAction func login(sender: AnyObject) {
let facebookLogin = FBSDKLoginManager()
facebookLogin.logInWithReadPermissions(["public_profile", "email", "user_friends"], fromViewController: self, handler: {
(facebookResult, facebookError) -> Void in
// some logic which isn't executed
})
}

这是我的 appdelegate:
//
// AppDelegate.swift
// RegelBaas
//
// Created by J. Weijland on 12-12-15.

import UIKit
import FBSDKCoreKit
import FBSDKLoginKit
import Batch
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Styling
UINavigationBar.appearance().barTintColor = UIColor(red: 1.0, green: (102/255), blue: (102/255), alpha: 1)
UINavigationBar.appearance().tintColor = UIColor.whiteColor()
FBSDKApplicationDelegate.sharedInstance()
.application(application, didFinishLaunchingWithOptions: launchOptions)
return true
}
func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool
{
return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)
}
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.
FBSDKAppEvents.activateApp()
}
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject])
{
}
}
我猜我的 appdelegate 有问题，因为我认为我的应用程序无法识别从 safari/FB 原生到我的应用程序的后退切换。奇怪的是在 iOS 9 中一切正常!
- “在 iOS 9 上运行”是指它可以在运行 iOS 9 的设备上运行。我正在使用 iOS SDK 9.2 进行编译。
最佳答案
正如我在上面的评论中所说:
(Yes,) I deleted UIApplicationExitsOnSuspend from the plist. This line made my app 'reset' everytime the app switched to Safari and back. That's why the debugger got detached also.
关于ios - iOS 8 上的 Facebook 登录；登录切换后应用程序无法运行，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/36489689/
