应用程序委托中用于 Facebook 和 Twitter 的 OpenURL？

Question

我正在使用 Facebook SDK 和 Twitter SDK 进行登录和注册。

但他们都没有通过一种常用方法打开 URL。我为 Facebook 编写了如下代码：

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
}

这很好用，对于 Twitter，我必须评论上面的方法并且必须这样写：

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

这仅适用于 Twitter。

问题是我需要写一个通用的方法来在appDelegate中打开他们的URL。那我该如何克服呢？

注意：我们不能在应用程序委托中同时编写这两个方法。

Answer 1

终于找到了这个问题的答案。

Swift 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的问题的人。

谢谢。

Answer 2

已更新 SWIFT 3

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
    let sourceApplication: String? = options[UIApplicationOpenURLOptionsKey.sourceApplication] as? String
    return FBSDKApplicationDelegate.sharedInstance().application(app, open: url, sourceApplication: sourceApplication, annotation: nil)
}

Answer 3

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options
{

  if ([Twitter.sharedInstance application:app openURL:url options:options])
{

return YES;

}

return [self application:app openURL:url sourceApplication:[options objectForKey:UIApplicationOpenURLOptionsSourceApplicationKey] annotation:[options objectForKey:UIApplicationOpenURLOptionsAnnotationKey]];

}

Answer 4

这是我尝试使用 Objective

的 Twitter 和 Facebook 的 openURL

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options {

if ([[url scheme] isEqualToString:FACEBOOK_SCHEME])
return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                      openURL:url
                                            sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]
                                                   annotation:nil];
if ([[url scheme] isEqualToString:TWITTER_SCHEME])
return [[Twitter sharedInstance] application:application openURL:url options:options];

return NO;
}

当然还有这些：

#define TWITTER_SCHEME @"Twitter-key-from-plistfile"
#define FACEBOOK_SCHEME  @"fb-key-from-plistfile"

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)
}

Answer 6

Swift 5

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey: Any] = [:]) -> Bool
{
    // Check for twitter 
    if TWTRTwitter.sharedInstance().application(app, open: url, options: options)
    {
        return true
    }
    
    // If twitter failed, check for facebook
    return ApplicationDelegate.shared.application(app, open: url, options: options)
}
