No reaction to Deep-link defined in info.plist - ios

i defined a deep-link in info.plist like this :
<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleURLName</key>
<string>com.myapp.customer</string>
<key>CFBundleURLSchemes</key>
<array>
<string>myapp.com</string>
</array>
</dict>
</array>
but in Safari there's no reaction to this link and this message shows up :
Safari cannot open the page because the server can not be found
Everything is checked and i did as tutorials and still nothing happens!

The CFBundleURLSchemes field should be filled with a scheme, not a url. Schemes come before the url to tell the browser what action to take. For example, https:// is a scheme that tells the browser to establish a secure connection. An Apple URI scheme is simply you telling the browser that you want URLs with your custom scheme (i.e. customScheme://) to be handled by your app. HTTP and HTTPS are reserved for Safari on iOS. To allow customScheme://example/path to open your app. Just change that field to customScheme.
If you would like to register normal web URLs to handle your links you will have to integrate Universal Links. These can be a pain to set up so I recommend using the Branch iOS SDK. Their deep linking is free and provides more features on top of Universal Links.

Make sure you have this method in AppDelegate.Swift
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
if url.scheme != nil && url.scheme!.hasPrefix(""){
//Deep linking link should be like this : 'yourAppScheme'
if(url.host?.contains("page"))!{
if(url.path.contains("/yourhoststring")){
// do some work
}
}
}
//default
return false
}
Your Url scheme should be like this : [scheme]://[host]/[path]

How can I know if external app will be open or not when a link is loaded in WKWebView?

I have a WKWebView, the webview will load a link like https://qr.payme.hsbc.com/2/XXXXYYYZZZ.
And there two possible results when the link is loaded,
case 1 is an app called Payme will be opened when user has installed Payme app;
case 2 is webview will be redirected to a static page https://payme.hsbc.com/ when user has not installed Payme app.
My question is how can I know if the Payme app is opened?
You could use deep linking or the apple recommended universal linking to check if an app is installed in a device. With deep linking what you need to do is to acquire a schema of the app that the app has already added. And you could check if the schema can be opened just like you would do for any other type of URLs. Here is an example:
let appSchemeString = "com.myAppScheme://"
let url = URL(string: appSchemeString)!
if UIApplication.shared.canOpenURL(url) {
print("App is present")
} else {
print("App is not")
}
You need to update your info.plist file to include the schemes you'll be opening in the application. You should append this:
<key>LSApplicationQueriesSchemes</key>
<array>
<string>com.myAppScheme</string>
</array>
Here is an entire youtube video link regarding this.

iOS Swift LinkedIn App URL Scheme is not working

I want to open user linedIn profile(in linkedIn Native App) from my App.
I tried this but its just opening linekdin App but not profile page: URL Scheme for Linkedin
I have added URLSchemes as well
<key>LSApplicationQueriesSchemes</key>
<array>
<string>linkedin</string>
</array>
This is my code
if let linkedinUrl = URL(string: "linkedin://profile?id=parmarvhv"),
UIApplication.shared.canOpenURL(linkedinUrl) {
UIApplication.shared.open(linkedinUrl, options: [:], completionHandler: nil)
}
LinkedIn Web Url is this: https://www.linkedin.com/in/parmarvhv/
What is the correct way to open user profile?
This code works for swift 5:
Opening a LinkedIn page:
linkedin://company/binance
Opening a LinkedIn profile:
linkedin://profile/binance
Well, it's not documented. so you can't rely on it.
But, using linkedin://in/{username} works for me.

Facebook logout programmatically in Xamarin ios in Visual Studio

I have an application in IOS in which there is a Facebook Login Button.
when ever user clicks this Facebook login button My app redirects the user to the Facebook App installed in my device. So I want to logout the user from the application as soon as he leaves the facebook app and comes to my app.
i redirect the user to the facebook app using
NSUrl url = NSUrl.FromString("fb://profile/<id>");
UIApplication.SharedApplication.OpenUrl(url);
I found the Facebook login documentation. As the documentation described, I think you have added the CFBundleURLTypes, like this:
<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleURLSchemes</key>
<array>
<string>fb[APP_ID]</string>
</array>
</dict>
</array>
It means that Facebook will trigger the openURL to return back to your app via the URLScheme you have set here.
So, you can override OpenUrl(UIApplication app, NSUrl url, NSDictionary options) in AppDelegate.cs, and the parameters url or options contain the information related to Facebook. So, you can identify the resource.
public override bool OpenUrl(UIApplication app, NSUrl url, NSDictionary options)
{
Console.WriteLine(url);
Console.WriteLine(options);
return true;
}
According to this, you can do the action you want when return back from Facebook.
Are you using the Xamarin Facebook SDK? If yes you can do this to log out:
new LoginManager().LogOut();

Integrating a Xamarin app with Facebook SSO w/ Facebook iOS App

I am writing a Xamarin iOS app and having difficulty integrating Facebook SSO, though I don't think my problem is necessarily Xamarin-specific, just a lack of understanding of how to integrate Facebook SSO without the benefit of the Facebook iOS SDK.
I have followed the various guides and have done the following:
1) Have a Facebook App set up:
a) iOS Platform added with bundle id matching my app's bundle id
b) Single sign on enabled
2) Set up my info.plist as follows:
raw text:
<key>CFBundleDisplayName</key>
<string>[company]</string>
<key>CFBundleIdentifier</key>
<string>com.[company].ios.app</string>
<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleURLSchemes</key>
<array>
<string>fb123490xxx</string>
</array>
<key>CFBundleURLName</key>
<string>com.[company].ios.app</string>
</dict>
</array>
<key>FacebookAppID</key>
<string>123490xxx</string>
<key>FacebookDisplayName</key>
<string>[company] Staging</string>
3) Implemented the following code in my app:
FacebookLoginButton.TouchUpInside += (sender, e) =>
{
var urlWithAppProtocol = new NSUrl("fb123490xxx://");
UIApplication.SharedApplication.OpenUrl(urlWithAppProtocol);
};
I have not overriden AppDelegates methods (OpenUrl and HandleOpenUrl) yet because as far as I can see those handle incoming redirects to my app; I will get that working next.
To be clear, what I'm expecting to see is the FB iOS App equivalent of this screen (from Mobile Safari)
However, if I redirect to:
"fb://[appid]" I get redirected to the FB app but just to the news feed page (or whatever screen I was on last when I was using the FB app)
"fb[appid]://" I get nothing happening, .OpenUrl() does nothing;
"fb://profile/[appid]" as an experiment, I get the following (notice the "app isn't available for your phone"); this could be because you're supposed to use the PageID with /profile.
What am I missing here?
Ok, in the end it was simply using fbauth://authorize in conjunction with the normal query string parameters in the oauth url. The redirect url needs to be fbconnect://success
I found this by reading the source code of the FB iOS SDK:
https://github.com/keithpitt/DKSocial/blob/72cd77bc15ca1a307b92aff8382f2c71a97da7de/External/FBConnect/Facebook.m
There might be a lesson here to use the Xamarin bindings of the official Facebook iOS SDK, which offers this functionality. I've ended up going down the manual route because I started with the Facebook .NET SDK, which doesn't seem to offer this App-based SSO functionality.

Phonegap ChildBrowser opening an External URL via a custom iOS url

I'm currently work on a iOS/Phonegap app, I want to have it respond to a custom URL scheme, so that when a person clicks on a link in the regular browser it will open the app to a specific page, where said page is actually an external page. The app thus far essentially acts as a web browser where external (web) content is displayed in ChildBrowser.
I am 95% certain I need to use the following method in AppDelegate.
- (BOOL) execute:(InvokedUrlCommand*)command{}
And I know I need to use the following to create my command.
+ (InvokedUrlCommand*) newFromUrl:(NSURL*)url;
My problem is that I've been unable to find any examples online of doing this. I know the url passed to newFromUrl needs to be in the format of yourscheme://<sessionKey>#<Class>.<command>/[<arguments>][?<dictionary>] But in this case, my [<arguments>] would be a regular url of the form "http://www.google.com".
Can some one give a concrete real-world example?
This is implemented in current versions of PhoneGap so that all you need to do is add you custom URL to the App-info.plist file. Here is a sample of the XML:
<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleURLName</key>
<string>com.cams.myapp</string>
<key>CFBundleURLSchemes</key>
<array>
<string>myApp</string>
</array>
</dict>
</array>
You should use the Property editor to edit this file and get the format correct.
