I successfully have a message url from the gmail api:
https://mail.google.com/mail/?authuser=roy#companyemail.co#all/155134b5e66a9b06
However, when i call the [[UIApplication sharedApplication] openURL:url] method, the web client gets opened up instead of the native iOS application (and just shows the inbox, not the specific message). Not sure if it has to do with the LSApplicationQueriesSchemes or not, but regardless - couldn't find any documentation on this in the Gmail iOS documentation, so if anyone has any ideas!
Thanks
Through the links the Brett posted, this deep link url allowed me to open gmail:
googlegmail://
Still searching for instructions on deep linking to a specific email though
It seems that the openURL method is designed to do what you want to do. But any URL which starts with http: or https: is going to open in Safari. Here is a quote from the doco.
A URL (Universal Resource Locator). UIKit supports many common
schemes, including the http, https, tel, facetime, and mailto schemes.
You can also employ custom URL schemes associated with apps installed
on the device.
I presume that if you wanted to compose a message in the built-in Mail app, you would use a mailto: URL. Not sure about opening an existing message. And if you want to open an existing message in another app, then that app would need to define a custom URL scheme, and you'd need to use that.

Any ideea how is this getting true in
appUrl = "http://dum:site2015#jobz.store.com/
if UIApplication.shared.canOpenURL(appUrl!){
if #available(iOS 10.0, *) {
UIApplication.shared.open(appUrl!)
}
and in url scheme i have jobz-com
the thing is it getting true althought I don't have the app installed ...instead is opening the url in safari... but why is not getting false since i don't have the app installed?
This function does not check for apps installed. It just tells you if it can open that URL, in safari or through an app.
A valid URL will always return true because the system can actually open it somewhere.
According to Apple's own documentation
A URL (Universal Resource Locator). At runtime, the system tests the URL’s scheme to determine if there is an installed app that is registered to handle the scheme. More than one app can be registered to handle a scheme.
https://developer.apple.com/documentation/uikit/uiapplication/1622952-canopenurl
Safari is registered to handle any valid URL, so if the app using the scheme does not exist, the next application registered to read it is safari.
I don't think there's an open API for you to only open an URL if the app is installed.
And always make sure that your URL starts with the scheme you need and not HTTP/S.
my-app://myurl/parameters
Do not use http:// or https:// to open apps. These are for websites. Use app url schemes like this:
jobz-com://
Edit
Another way of doing what the questioner is trying to achieve is to use Universal Link.
Here is the Apple's Official doc about Universal Links and you can follow this medium article which says:
The workaround approach to deep linking with URI schemes involves
using a traditional http:// link to launch a web browser. This link
contains a JavaScript redirect to a custom URI scheme, which is
executed by the web browser to launch the app. If the redirect attempt
fails because the app is not installed, the JavaScript then takes the
user to the App Store or Play Store.
Instead of opening up
Safari first when a link is clicked, iOS will check if a Universal
Link has been registered (an AASA (apple-app-site-association) file
should be there in the domain which contains the bundle id of the app
and the paths the app should open) for the domain associated with the
link, then check if the corresponding app is installed. If the app is
currently installed, it will be opened. If it’s not, Safari will open
and the http(s) link will load.
How can I add deeplink (url like https://www.example.com) in iOS using swift.
The scheme in plist is not working if I enter url in it.
You can check the screenshot of plist attached.
You are attempting to register your app for the URI scheme https which Apple has already reserved for Safari, therefore you will not be able to use it.
Option 1: Custom URI Scheme
You must come up with a custom URI scheme like customURI://www.domain.com
Downside: If a user clicks on this link without the app installed. iOS will show that user and error.
Option 2:Universal Links
Apple launched Universal Links in iOS 9 to enable developers to associate their http link with their app. This requires you to host your own AASA file on your domain so that your domain becomes associated with your app ID.
Option 3: Branch.io
Branch will actually bundle up Universal Links and URI schemes and use them appropriately when necessary. They also perform deferred deep linking. They'll host your AASA file for you, but your app domain will have to be either https://*.app.link or some dedicated subdomain of a domain that you own.
only to be precise:
If you need more docs about in Apple docs, use the CORRECT name for the technology.
If You use url starting with a schema different from http (for example fb:// for FB) is not a LINK, is a "custom" url.
Anyway use: custom url and see at:
https://developer.apple.com/library/content/documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/Inter-AppCommunication/Inter-AppCommunication.html
First of all, I know how to make custom schemes in iOS and I know how to open my app from a website using a javascript setTimeout method.
I have an app that uses custom URL scheme and it is working great. What it does is, it sends a http://testsite.com/QueryStrings message to other users in the contact list (predefined) and on clicking those web links in the sms, these things happen:
Open the link in Safari
Open the app if installed with custom url using setTimeout
If not installed, move to the normal website page
What I wanted actually is to open my app directly from SMS if installed but for that I have to send my custom url scheme in the SMS, that is not an option because if app is not installed then this SMS wont work so a weblink is the only option for now.
Today, I installed SoundCloud and accidentally noticed this thing is that when http:// m. soundcloud .com /... url is sent in an SMS and on clicking the link it opens the app (if installed) directly not the Safari (Strange for me).
So I was wondering how come their app open from a web link without opening the Safari. I googled it around but I couldn't find a solution to my problem. I am attaching a screenshot too from my mobile where press and hold on the link in the messages app give Open in "SoundCloud" option as well. So how SoundCloud registered a http link to be handled automatically in the app. Please help guys

The answer to this problem is using Associated Domains (But after 9.2 we have to use Universal Links to achieve this).
Before Universal Links, the primary mechanism to open up an app when it was installed was by trying to redirect to an app’s URI scheme (registered in the app’s PLIST like so) in Safari. This put the routing logic in Safari, but there was no way to check if the app was installed or not.
iOS 9 Universal Links were intended to fix this. Instead of opening up Safari first when a link is clicked, iOS will check if a Universal Link has been registered for the domain associated with the link, then check if the corresponding app is installed. If the app is currently installed, it will be opened. If it’s not, Safari will open and the http(s) link will load.
Functionally, it allows you have a single link that will either open your app or open your mobile site.
Configure your app to register approved domains
Registered your app at developers.apple.com
Enable ‘Associated Domains’ on your app identifier
Enable ‘Associated Domain’ on in your Xcode project
Add the proper domain entitlement
Make sure the entitlements file is included at build
Configure your website to host the ‘apple-app-site-association’ file
Buy a domain name or pick from your existing
Acquire SSL certification for the domain name
Create structured ‘apple-app-site-association’ JSON file
Sign the JSON file with the SSL certification
Configure the file server
Apple launched Universal Links in iOS 9.0, which moves the app routing into the OS so that developers don’t need to worry about doing the routing in Javascript.
Receiving Universal Link URL in the App
URI schemes received the deep link URL through openUrl in the App Delegate. Universal Links receive their data via a different code path: continueUserActivity. This new delegate method is used for a number of app transitions, ranging from Spotlight to Universal Links, and will likely see a couple more use cases introduced in future OS versions.
Below is a snippet of code that you can use to retrieve the full Universal Link URL that opened the app.
- (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void (^)(NSArray *))restorationHandler {
if ([userActivity.activityType isEqualToString:NSUserActivityTypeBrowsingWeb]) {
NSString *myUrl = [userActivity.webpageURL absoluteString];
// parse URL string or access query params
}
return YES;
}

Is there a way to intercept URLs on iOS (iphone/iPad) such that a URL from a specific host is always opened by my app and not by the browser?
Example: http://myapp.com/ref/123 -> gets opened by my app and I parse out the 123
Update
I find it really weird that this isn't allowed on iOS (iphone/ipad). On Android I've been able to intercept a url and whenever it begins with http://myapp... it gets opened in my app.
How does the community solve the issue of: Say a user who has my app installed on their iphone gets a link from a friend in an email. When they click it, if the link can't be opened in my app...how else am I suppose to do anything good with the shared url? OR should I not be passing http:// links but myapp:// instead??
The scheme name (or protocol) of a URL is the first part of a URL - e.g. schemename://. For web pages, the scheme is usually http (or https). The iPhone supports these URL schemes:
http, https, ftp Web links* (Safari)
mailto E-mail links (launches the Mail app)
tel Telephone Numbers (launches the phone app)
sms Text Messages (launches the SMS app)
iPhone apps can specify their own custom URL scheme (for example, myapp://doStuff). But it's not possible to redirect a specific http host to be opened by your app.
To add a custom URL scheme to your app follow this guide,
Custom URL schemes
Is it possible for a web app to make use of the box:// url-scheme with parameters to open a specific file in the Box iOS app?
The Android Box app has a similar function with its intent links.
And if it is possible, what would these parameters be? (already using Oauth2 API to list files with shared links).
boxopendirect://file?id=<fileid> to redirect to a file.
boxopendirect://folder?id=<folderid> to redirect to a folder
It certainly is possible to open other apps from inside a webapp using a proprietary scheme identifier. Unfortunately, you will need to know the exact scheme syntax in advance. There's a good list of them available here:
http://wiki.akosma.com/IPhone_URL_Schemes
For example, to open the youtube app directly, you can use:
youtube://
