处理两个应用程序:openURL:sourceApplication:annotation

Question

我有2个需要使用该application:openURL:sourceApplication:annotation方法的SDK .一个是FacebookSDK,第二个是GooglePlusSDK.

这些是方法:

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
    return [FBAppCall handleOpenURL:url sourceApplication:sourceApplication];
}

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
    return [GPPURLHandler handleURL:url sourceApplication:sourceApplication annotation:annotation];
}

我的问题是如何将它们迁移到一个方法中？什么是最好的方法？

提前致谢.

Answer 1

使用逻辑OR运算符 ||

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
    return [FBAppCall handleOpenURL:url sourceApplication:sourceApplication] || [GPPURLHandler handleURL:url sourceApplication:sourceApplication annotation:annotation];
}

Swift版本

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String!, annotation: AnyObject) -> Bool {
    return FBAppCall.handleOpenURL(url, sourceApplication: sourceApplication) || GPPURLHandler.handleURL(url, sourceApplication: sourceApplication, annotation: annotation)
}

Answer 2

你可能会这样做:

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
    BOOL shouldOpen = [FBAppCall handleOpenURL:url sourceApplication:sourceApplication];
    shouldOpen = shouldOpen ? shouldOpen : [GPPURLHandler handleURL:url sourceApplication:sourceApplication annotation:annotation];

    return shouldOpen;
}

一种更清洁的方式(在Swift中)将是:

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String!, annotation: AnyObject) -> Bool {
    var handled: Bool
    if let facebook = url.scheme?.hasPrefix("fb") {
        handled = FBAppCall.handleOpenURL(url, sourceApplication: sourceApplication)
    } else {
        handled = GPPURLHandler.handleURL(url, sourceApplication: sourceApplication, annotation: annotation)
    }
    // include any specific handling code as necessary
    return handled
}
