3 ## Welcome to the GStreamer iOS tutorials
5 These tutorials describe iOS-specific topics. General GStreamer
6 concepts will not be explained in these tutorials, so the
7 [](tutorials/basic/index.md) should be reviewed first. The reader should
8 also be familiar with basic iOS programming techniques.
10 The iOS tutorials have the same structure as the
11 [](tutorials/android/index.md): Each one builds on top of the previous
12 one and adds progressively more functionality, until a working media
13 player application is obtained in
14 [](tutorials/ios/a-complete-media-player.md).
16 Make sure to have read the instructions in
17 [](installing/for-ios-development.md) before jumping into the iOS
20 All iOS tutorials are split into the following classes:
22 - The `GStreamerBackend` class performs all GStreamer-related tasks
23 and offers a simplified interface to the application, which does not
24 need to deal with all the GStreamer details. When it needs to
25 perform any UI action, it does so through a delegate, which is
26 expected to adhere to the `GStreamerBackendDelegate` protocol.
27 - The `ViewController` class manages the UI, instantiates the
28 `GStreamerBackend` and also performs some UI-related tasks on its
30 - The `GStreamerBackendDelegate` protocol defines which methods a
31 class can implement in order to serve as a UI delegate for the
