# Welcome to the GStreamer SDK iOS tutorials
|
|
|
|
|
|
|
|
|
|
|
|
These tutorials describe iOS-specific topics. General GStreamer concepts
|
|
|
|
|
|
will not be explained in these tutorials, so the [Basic
|
|
|
|
|
|
tutorials](http://docs.gstreamer.com/display/GstSDK/Basic+tutorials) should
|
|
|
|
|
|
be reviewed first. The reader should also be familiar with basic iOS
|
|
|
|
|
|
programming techniques.
|
|
|
|
|
|
|
|
|
|
|
|
The iOS tutorials have the same structure as the [Android
|
|
|
|
|
|
tutorials](Android%2Btutorials.html): Each one builds on top of the
|
|
|
|
|
|
previous one and adds progressively more functionality, until a working
|
|
|
|
|
|
media player application is obtained in [iOS tutorial 5: A Complete
|
|
|
|
|
|
media
|
|
|
|
|
|
player](http://docs.gstreamer.com/display/GstSDK/iOS+tutorial+5%3A+A+Complete+media+player).
|
|
|
|
|
|
|
|
|
|
|
|
Make sure to have read the instructions in [Installing for iOS
|
|
|
|
|
|
development](Installing%2Bfor%2BiOS%2Bdevelopment.html) before jumping
|
|
|
|
|
|
into the iOS tutorials.
|
|
|
|
|
|
|
|
|
|
|
|
All iOS tutorials are split into the following classes:
|
|
|
|
|
|
|
|
|
|
|
|
- The `GStreamerBackend` class performs all GStreamer-related tasks
|
|
|
|
|
|
and offers a simplified interface to the application, which does not
|
|
|
|
|
|
need to deal with all the GStreamer details. When it needs to
|
|
|
|
|
|
perform any UI action, it does so through a delegate, which is
|
|
|
|
|
|
expected to adhere to the `GStreamerBackendDelegate` protocol.
|
|
|
|
|
|
- The `ViewController` class manages the UI, instantiates the
|
|
|
|
|
|
`GStreamerBackend` and also performs some UI-related tasks on its
|
|
|
|
|
|
behalf.
|
|
|
|
|
|
- The `GStreamerBackendDelegate` protocol defines which methods a
|
|
|
|
|
|
class can implement in order to serve as a UI delegate for the
|
|
|
|
|
|
`GStreamerBackend`.
