URL schema is a way to identify and launch applications on iOS devices. It is the first part of a URL (e.g., schemaname://).
For web pages, the common schemas are http and https.
iOS supports these URL schemas:
- http, https, ftp - Web links that open in the Browser app.
- mailto - Email links that open the Mail app.
- tel - Phone numbers that open the Phone app.
- sms - Text messages that open the SMS app on iPhones.
URL schemas are used to launch applications from a browser or another app on your iPhone or iPad. Developers can create and register their own custom URL schemas.
