Question

当我使用新版本更新我的应用程序时，会调用openURL方法。但是，当我点击动态链接并在此之后进行更新时，不再调用openURL方法。

有人可以解释为什么会这样吗？

这是我想用openURL方法/

做事的代码

- (BOOL)application:(UIApplication *)application

        openURL:(NSURL *)url

        options:(NSDictionary<NSString *, id> *)options {



// Sends the URL to the current authorization flow (if any) which will

// process it if it relates to an authorization response.

if ([_currentAuthorizationFlow resumeAuthorizationFlowWithURL:url]) {

    _currentAuthorizationFlow = nil;

    return YES;

}



FIRDynamicLink *dynamicLink = [[FIRDynamicLinks dynamicLinks] dynamicLinkFromCustomSchemeURL:url];

NSString *userID = [[NSUserDefaults standardUserDefaults] stringForKey:@"xx"];

NSString *firstTimeAppOpened = [[NSUserDefaults standardUserDefaults] stringForKey:@"xxx"];


if (dynamicLink != nil) {

    if ([dynamicLink.url.absoluteString length] != 0) {

        NSLog(@"App opened with link: %@", dynamicLink);



        NSString *snippet = [NSString stringWithFormat:@"URLScheme: Received dynamic firebase link: %@", dynamicLink.url.absoluteString];

        NSString *category = @"DYNAMIC_LINK";

        NSString *pathFromURL = [dynamicLink.url.absoluteString lastPathComponent];


        [SiteConnector sendAuditWithSnippet:snippet inCategory:category];



        NSString *firstTimeAppOpened = [[NSUserDefaults standardUserDefaults] stringForKey:@"FirstTimeAppOpened"];



        if ([dynamicLink.url.absoluteString rangeOfString:@"murat"].location == NSNotFound) {

            [self dynamicLinkBehaviour:pathFromURL second:dynamicLink.url absolutePath:nil];

        } else {

            if (firstTimeAppOpened == nil) {

                [self onboardingDynamicLink:dynamicLink.url.absoluteString];

            }

        }

    }

    else {

        if (userID == nil && firstTimeAppOpened == nil) {

            [self openWelcomeScreen];

        }

    }

}



NSString *valueToSave = @"yes";

[[NSUserDefaults standardUserDefaults] setObject:valueToSave forKey:@"FirstTimeLoggedIn"];

[[NSUserDefaults standardUserDefaults] synchronize];



return [[FBSDKApplicationDelegate sharedInstance] application:application

                                                      openURL:url

                                            sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]

                                                   annotation:options[UIApplicationOpenURLOptionsAnnotationKey]];

}

openURL仅在通过URI方案（即fb://）打开应用时调用。在大多数情况下，Firebase使用通用链接，通用链接打开的应用会触发continue userActivity协议功能。您可以参考他们的文档获取该代码：

func application(_ application: UIApplication, continue userActivity: NSUserActivity,
                 restorationHandler: @escaping ([Any]?) -> Void) -> Bool {
  guard let dynamicLinks = DynamicLinks.dynamicLinks() else {
    return false
  }
  let handled = dynamicLinks.handleUniversalLink(userActivity.webpageURL!) { (dynamiclink, error) in
    // ...
  }

  return handled
}

这是我推荐使用Branch的一个原因，因为他们在一次回调中处理它们，无论它是URI方案还是通用链接。

你好@IOSporgrammerIOS请试试这个。

 
var yourUrl = NSURL(string:"url_String")!

 if UIApplication.shared.canOpenURL(yourUrl as URL){

     UIApplication.shared.openURL(yourUrl as URL)

  }

目标C


    UIApplication *application = [UIApplication sharedApplication];
    NSURL *URL = [NSURL URLWithString:@"http://www.google.com"];

     [application openURL:URL options:@{} completionHandler:^(BOOL success) 
   {
        if (success) {

            NSLog(@"Opened url");
       }
 }];

首次使用动态链接下载后更新应用程序时，不会调用openURL方法
