iOS Unified Deep Linking
概览:统一深度链接(UDL)使您能够在应用程序打开后立即将新用户和现有用户发送到特定的应用内行为(例如,应用程序中的特定页面)。
UDL隐私保护
For new users, the UDL method only returns parameters relevant to deferred deep linking:
deep_link_value
anddeep_link_sub1-10
. If you try to get any other parameters (media_source
,campaign
,af_sub1-5
, etc.), they return null.
流程
流程如下:
- 用户点击OneLink链接。
- 如果用户安装了应用程序,通用链接或URI方案将打开该应用程序。
- 如果用户没有安装应用程序,他们会被重定向到应用商店,下载后,用户会打开该应用程序。
- 应用程序打开后会触发AppsFlyer SDK。
- AppsFlyer SDK运行UDL API。
- UDL API从AppsFlyer服务器检索OneLink数据。
- The UDL API calls back the
didResolveDeepLink()
in theDeepLinkDelegate
. - The
didResolveDeepLink()
method gets aDeepLinkResult
object. - The
DeepLinkResult
object includes:- 状态(找到/未找到/失败)
- A
DeepLink
object that carries thedeep_link_value
anddeep_link_sub1-10
parameters that the developer uses to route the user to a specific in-app activity, which is the main goal of OneLink.
规划
- UDL需要AppsFlyer iOS SDK V6.1+。
When setting up OneLink, the marketer uses parameters to create the links, and the developer customizes the behavior of the app based on the values received. It is the developer's responsibility to make sure the parameters are handled correctly in the app, for both in-app routing, and personalizing data in the link.
规划OneLink:
- 从营销人员处获得用户点击URL时所需的行为和个人体验。
- Based on the desired behavior, plan the
deep_link_value
and other parameters that are needed to give the user the desired personal experience.- The
deep_link_value
is set by the marketer in the URL and used by the developer to redirect the user to a specific place inside the app. For example, if you have a fruit store and want to direct users to apples, the value ofdeep_link_value
can beapples
. - The
deep_link_sub1-10
parameters can also be added to the URL to help personalize the user experience. For example, to give a 10% discount, the value ofdeep_link_sub1
can be10
.

实现

Set Deep Linking with our SDK integration wizard
根据所选参数和值实现UDL API逻辑。
- Assign the
AppDelegate
usingself
toAppsFlyerLib.shared().deepLinkDelegate
. - Implement application function to allow:
- Universal Links support with
continue
. - URI scheme support with
handleOpen
.
- Universal Links support with
- Create
DeepLinkDelegate
as an extension ofAppDelegate
. - Add
application
functions to support Universal Links and URI schemes. - In
DeepLinkDelegate
, make sure you override the callback function,didResolveDeepLink()
.
didResolveDeepLink()
accepts aDeepLinkResult
object as an argument. - Use
DeepLinkResult.status
to query whether the deep linking match is found. - For when the status is an error, call
DeepLinkResult.error
and run your error flow. - For when the status is found, use
DeepLinkResult.deepLink
to retrieve theDeepLink
object.
TheDeepLink
object contains the deep linking information arranged in public variables to retrieve the values from well-known OneLink keys, for example,DeepLink.deeplinkValue
fordeep_link_value
. - Use
deepLinkObj.clickEvent["deep_link_sub1"]
to retrievedeep_link_sub1
. Do the same fordeep_link_sub2-10
parameters, changing the string value as required. - Once
deep_link_value
anddeep_link_sub1-10
are retrieved, pass them to an in-app router and use them to personalize the user experience.
Supporting legacy OneLink links
Legacy OneLink links are links that don't contain the parameters recommended for Unified Deep Linking: deep_link_value
and deep_link_sub1-10
.
Usually these are links that already exist in the field when migrating from legacy methods to UDL.
News users using legacy links are handled by onConversionDataSuccess
in the context of extended deferred deep linking.
UDL handles deep linking for existing users. It's recommended that you add support in the UDL callback didResolveDeepLink
for legacy parameters.
Swift code example
Code example
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Replace 'appleAppID' and 'appsFlyerDevKey' with your Apple App ID (eg 69999999, without id prefix) and DevKey
// The App ID and the DevKey must be set prior to the calling of the deepLinkDelegate
AppsFlyerLib.shared().appleAppID = appleAppID
AppsFlyerLib.shared().appsFlyerDevKey = appsFlyerDevKey
...
AppsFlyerLib.shared().deepLinkDelegate = self
...
}
// For Swift version < 4.2 replace function signature with the commented out code
// func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([Any]?) -> Void) -> Bool { // this line for Swift < 4.2
func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {
AppsFlyerLib.shared().continue(userActivity, restorationHandler: nil)
return true
}
// Open URI-scheme for iOS 9 and above
func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
AppsFlyerLib.shared().handleOpen(url, options: options)
return true

Deferred Deep Linking after network consent
In some cases the application might require consent from the user in order to connect to the network, in a dialog similar to this one:
In order to support deferred deep linking once the network consent is given we recommend:
- Implement eDDL to allow UDL to handle the deferred deep linking
Testing deferred deep linking
Prerequisites
- Complete UDL integration.
- Register your testing device.
- Enable debug mode in the app.
- Make sure the app isn't installed on your device.
- Ask your marketer for a OneLink template.
- It will look something like this
https://onelink-basic-app.onelink.me/H5hv
. - This example uses the OneLink subdomain
onelink-basic-app.onelink.me
and the OneLink template IDH5hv
.
- It will look something like this
The test link
You can use an existing OneLink link or ask your marketer to create a new one for testing. Both short and long OneLink URLs can be used.
Adding ad-hoc parameters to an existing link
- Use only the domain and OneLink template of your link. For example:
https://onelink-basic-app.onelink.me/H5hv
. - Add OneLink parameters
deep_link_value
anddeep_link_sub1-10
as expected by your application. The parameters should be added as query parameters.- 示例:
https://onelink-basic-app.onelink.me/H5hv?pid=my_media_source&deep_link_value=apples&deep_link_sub1=23
- 示例:
Perform the test
- Click the link on your device.
- OneLink redirects you according to the link setup, to either the App Store or a website.
- Install the application.
注意事项
- If the application is still in development and not uploaded to the store yet, you see this image:
- Install the application from Xcode.
- If the application is still in development and not uploaded to the store yet, you see this image:
- UDL detects the deferred deep linking, matches the install to the click, and retrieves the OneLink parameters to
didResolveDeepLink
callback.
Expected logs results
The following logs are available only when debug mode is enabled.
- SDK initialized:
[AppsFlyerSDK] [com.apple.main-thread] AppsFlyer SDK version 6.6.0 started build
- UDL API starts:
D/AppsFlyer_6.9.0: [DDL] start
- UDL sends query to AppsFlyer to query a match with this install:
[AppsFlyerSDK] [com.appsflyer.serial] [DDL] URL: https://dlsdk.appsflyer.com/v1.0/ios/id1512793879?sdk_version=6.6&af_sig=efcecc2bc95a0862ceaa7b62fa8e98ae1e3e022XXXXXXXXXXXXXXXX
- UDL got a response and calls
didResolveDeepLink
callback withstatus=FOUND
and OneLink link data:[AppsFlyerSDK] [com.appsflyer.serial] [DDL] Calling didResolveDeepLink with: {"af_sub4":"","click_http_referrer":"","af_sub1":"","click_event":{"af_sub4":"","click_http_referrer":"","af_sub1":"","af_sub3":"","deep_link_value":"peaches","campaign":"","match_type":"probabilistic","af_sub5":"","campaign_id":"","media_source":"","deep_link_sub1":"23","af_sub2":""},"af_sub3":"","deep_link_value":"peaches","campaign":"","match_type":"probabilistic","af_sub5":"","media_source":"","campaign_id":"","af_sub2":""}
Testing deep linking (Universal Links)
Prerequisites
- Complete UDL integration.
- Register your testing device.
- Enable debug mode in the app.
- Make sure the app is already installed on your device.
- Ask your marketer for a OneLink template.
- It will look something like this
https://onelink-basic-app.onelink.me/H5hv
. - This example uses the OneLink subdomain
onelink-basic-app.onelink.me
and the OneLink template IDH5hv
- It will look something like this
- Configure Universal Links.
Create the test link
Use the same method as in deferred deep linking.
Perform the test
- Click the link on your device.
- UDL detects the Universal Link and retrieves the OneLink parameters to
didResolveDeepLink
callback.
Expected logs results
The following logs are available only when debug mode is enabled.
- If the link is a OneLink shortlink (e.g. https://onelink-basic-app.onelink.me/H5hv/apples):
[AppsFlyerSDK] [com.apple.main-thread] NSUserActivity `webpageURL`: https://onelink-basic-app.onelink.me/H5hv/apples [AppsFlyerSDK] [com.appsflyer.serial] UniversalLink/Deeplink found: https://onelink-basic-app.onelink.me/H5hv/apples [AppsFlyerSDK] [com.appsflyer.serial] Shortlink found. Executing: https://onelink.appsflyer.com/shortlink-sdk/v2/H5hv?id=apples ... [AppsFlyerSDK] [com.appsflyer.serial] [Shortlink] OneLink:{ c = test1; campaign = test1; "deep_link_sub1" = 23; "deep_link_value" = peaches; "is_retargeting" = true; "media_source" = SMS; pid = SMS; }
- UDL calls
didResolveDeepLink
callback withstatus=FOUND
and OneLink link data:[AppsFlyerSDK] [com.appsflyer.serial] [DDL] Calling didResolveDeepLink with: {"af_sub4":null,"click_http_referrer":null,"af_sub1":null,"click_event":{"campaign":"test1","deep_link_sub1":"23","deep_link_value":"peaches","media_source":"SMS"},"af_sub3":null,"deep_link_value":"peaches","campaign":"test1","match_type":null,"af_sub5":null,"media_source":"SMS","campaign_id":null,"af_sub2":null}
