Swift SDKApplicationDelegate未解析标识符的使用

我已经为facebook登录安装了两个pod

pod 'FacebookCore'
pod 'FacebookLogin'

而不是在appdelegate中导入FacebookCore。它仍然显示未解决的标识符错误的使用

我还在info.plist中实现了标记

<array>
<string>fb---------</string>
</array>
<key>FacebookAppID</key>
<string>-----------</string>
<key>FacebookDisplayName</key>
<string>-----------</string>

其原因是

SDKApplicationDelegate

更改为

ApplicationDelegate

func application(_ app: UIApplication, open url: URL,
                 options: [UIApplication.OpenURLOptionsKey: Any]) -> Bool {
    if ApplicationDelegate.shared.application(app, open: url, options: options) {
        return true
    }
    return false
}

还有一件事要做

class AppDelegate: UIResponder, UIApplicationDelegate

也要导入这两个豆荚

import FBSDKCoreKit
import FBSDKLoginKit

要让facebook登录，请添加以下两种方法

func application(_ app: UIApplication,open url: URL,options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool{

    if #available(iOS 9.0, *) {
        let sourceApplication: String? = options[UIApplication.OpenURLOptionsKey.sourceApplication] as? String
        return FBSDKApplicationDelegate.sharedInstance().application(app, open: url,sourceApplication: sourceApplication, annotation: nil)
    }

    return true
}

func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {

    return FBSDKApplicationDelegate.sharedInstance().application(application, open: url as URL?, sourceApplication: sourceApplication, annotation: annotation)
}

细节

• Xcode版本10.3（10G8）
• 斯威夫特5
• FacebookCore（0.7.0）

解决方案 只需将

SDKApplicationDelegate

替换为

ApplicationDelegate

func application(_ app: UIApplication, open url: URL,
                 options: [UIApplication.OpenURLOptionsKey: Any]) -> Bool {
    if ApplicationDelegate.shared.application(app, open: url, options: options) {
        return true
    }
    return false
}

我犯的错误是。。。使用未解析标识符“ApplicationLegate”；你是说“大使”吗？将“ApplicationLegate”替换为“UIApplicationLegate”。此返回语句是否适用于所有应用程序切换？我有谷歌，linkedIn，facebook。那么这只适用于facebook还是所有人？@KrutikaSonawala……是的，请看这个谢谢你的帮助。不确定facebook为什么没有快速入门指南行，错误是：使用未解析标识符“FBSDKApplicationDelegate”；你是说“大使”吗？将“FBSDKApplicationDelegate”替换为“UIApplicationDelegate”，导入将转换与上述答案相同的代码。这是有效的。这是截至2019年7月swift 5的规定。谢谢你的问题解决了我的问题，而不是答案，谢谢：）
