# iOS tutorials

# 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`.
