应用程序委托中的Facebook和Twitter的OpenURL？

Question

我使用Facebook SDK和Twitter SDK进行登录和注册.

但他们都没有从一种常见的方法打开网址.就像我为Facebook编写的代码如下,

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool
{
    if(url.scheme == "fb1651015905222312")
    {
        return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)
    }
    return true
}

这工作正常,对于twitter我必须评论上面的方法,并且必须写它,像

 func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {
    if Twitter.sharedInstance().application(app, openURL:url, options: options) {
        return true
    }
    return true
}

这适用于Twitter.

问题是我需要编写一个常用方法来在appDelegate中打开他们的URL.那我怎么克服它？

提前致谢.

注意:我们不能在app delegate中编写这两种方法.

最后我找到了这个问题的解决方案.

斯威夫特3

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

    if Twitter.sharedInstance().application(app, open:url, options: options) {
        return true
    }


    let appId = SDKSettings.appId
    if url.scheme != nil && url.scheme!.hasPrefix("fb\(appId)") && url.host ==  "authorize" { // facebook
        return SDKApplicationDelegate.shared.application(app, open: url, options: options)
    }
    return false
}

对于Swift <3

这是允许我为Facebook和Twitter编写URL的方法.

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

    if Twitter.sharedInstance().application(app, openURL:url, options: options) {
        return true
    }

    let sourceApplication: String? = options[UIApplicationOpenURLOptionsSourceApplicationKey] as? String
    return FBSDKApplicationDelegate.sharedInstance().application(app, openURL: url, sourceApplication: sourceApplication, annotation: nil)
}

感谢所有试图回答我问题的人.

谢谢.

Answer 2

这适用于Swift 3和Swift 4.只需复制并粘贴:

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
    if Twitter.sharedInstance().application(app, open: url, options: options) {
        return true
    }

    let sourceApplication: String? = options[UIApplicationOpenURLOptionsKey.sourceApplication] as? String
    return FBSDKApplicationDelegate.sharedInstance().application(app, open: url, sourceApplication: sourceApplication, annotation: nil)
}
