By Alexander Rinass On January 16, git towerurl scheme. A URL Scheme is like "http: Those seem like a very low-level concept that you don't have much control over, but actually, you do! What sounds like an exotic topic is not so exotic at all: For example when we're clicking a link to an iPhone app that launches the AppStore. Or bitcoin url scheme list a friend sends us a link to a playlist and it opens in the Spotify desktop app.
Any macOS or iOS application can register itself as a handler for any URL scheme like "http" or "https" or document type like "txt" files. Apart from those classics, however, an app can also register its own, custom URL scheme or document format. If an app wants to indicate that it supports a certain document type or URL scheme, its "Info.
In your own app, you can configure this easily via Xcode's project settings: This enables the application to work with the configured types, for example, when opening files from Finder with "Open With" or handing off documents from one application to another on iOS. In general, registering your own custom bitcoin url scheme list allows you to route events directly to your application. When the user opens a URL with this scheme.
As an example, let's look at Towerthe Git desktop client that my team makes: Another use case for us is to make registering Tower easier for our users.
After purchasing a license, our customers receive an email that contains a link like this one: This will launch Tower or bring it to front and open bitcoin url scheme list registration dialog with the license information pre-filled. This is much for comfortable than fumbling with copy and paste only to notice that you missed a character or included unwanted ones On iOS, the use cases are very similar: To make a long story short: Let's get our hands dirty and create our own application that handles a custom URL scheme.
The sample code for this little tutorial can be found here. The first step is to register the application as a handler for our custom URL scheme, in our project's Info. Thereby, we ceremoniously offer to take the role of "Viewer" for the URL scheme foo. For more information and a detailed explanation of all the possible configuration keys, you can have a look at Apple's Property List Key Reference. The next step is to tell our application how to handle events that come in via our URL scheme.
For iOS applications, this is as simple as implementing the following delegate:. We first create an empty method with the expected signature in our AppDelegate class:. Now, if you'd build and run the application, the event would be correctly passed to our callback method - but it's still empty and won't do anything. The callback methods receive the incoming event as event: NSAppleEventDescriptor has lots of properties and methods. If you only care for the URL, the following implementation will do the trick:.
Once you have bitcoin url scheme list URL, it's up to you to translate it bitcoin url scheme list an action you want your application to perform. Apart from our own gittower scheme, Tower supports two additional ones: Of course we don't "blindly" bitcoin url scheme list other handlers! The macOS example project demonstrates how to use this class: Custom URL schemes are a great way to deep-link into your application and trigger actions.
They are easy to set up especially on iOS and provide your users with convenient shortcuts when coming from other applications. The main difference is that a URL scheme only works if the app is installed.
A universal link, being a regular link to a bitcoin url scheme list page, works regardless of whether or not the app is installed. This leads to a much better user experience.
For those wondering about other platforms, this is also supported on Windows and Android. Android also supports linking to applications with standard http: Xcode Project Settings This enables the application to work with the configured types, for example, when opening files from Finder with "Open With" or handing off documents from one application to another on iOS.
Use Cases for Custom URL Schemes In general, registering your own custom scheme allows bitcoin url scheme list to route events directly to your application. For iOS applications, this is as simple as implementing the following delegate: We first create an empty method with the expected signature in our AppDelegate class: If you only care for the Bitcoin url scheme list, the following implementation will do the trick: Registering an App as the Default Handler Apart from our own gittower scheme, Tower supports two additional ones: Have fun creating your own URL schemes!
