Building the application

What's new

Now the default way of building linphone-iphone is to use CocoaPods to retrieve the linphone-sdk frameworks. Compared to previous versions, this project no longer uses submodules developper has to build in order to get a working app. However, if you wish to use a locally compiled SDK, read paragraph "Using a local linphone SDK" below to know how to proceed.

Building the app

If you don't have CocoaPods already, you can download and install it using :

	sudo gem install cocoapods

Install the app's dependencies with cocoapods first:

	pod install

It will download the linphone-sdk from our gitlab repository so you don't have to build anything yourself.

Then open linphone.xcworkspace file (NOT linphone.xcodeproj) with XCode to build and run the app.

Testing the application

We are using the Xcode test navigator to test the UI of Linphone.

Change the Scheme to LinphoneTester. Press the test navigator button and all the tests will show. See: https://developer.apple.com/library/archive/documentation/DeveloperTools/Conceptual/testing_with_xcode/chapters/05-running_tests.html

Limitations and known bugs

Video capture will not work in simulator (not implemented in it).

Using a local linphone SDK

Clone the linphone-sdk repository from out gitlab:

   git clone https://gitlab.linphone.org/BC/public/linphone-sdk.git --recursive

Follow the instructions in the linphone-sdk/README file to build the SDK.
Rebuild the project:

   PODFILE_PATH=<path to linphone-sdk-ios> pod install

where is your build directory of the linphone-sdk project, containing the linphone-sdk.podspec file and a linphone-sdk ouptut directory comprising built frameworks and resources.

Then open linphone.xcworkspace with Xcode to build and run the app.

Enabling crashlythics

We've integrated Crashlythics into liphone-iphone, which can automatically send crash reports. It is disabled by default. To activate it:

Replace the GoogleService-Info.plist for this project with yours (specific to your crashlytics account).
Rebuild the project:

    USE_CRASHLYTHICS=true pod install

Then open linphone.xcworkspace with Xcode to build and run the app.

Quick UI reference

The app is contained in a window, which resides in the MainStoryboard file.
The delegate is set to LinphoneAppDelegate in main.m, in the UIApplicationMain() by passing its class

Basic layout:

  MainStoryboard
          |
          | (rootViewController)
          |
      PhoneMainView ---> view |--> app background
          |                   |
          |                   |--> statusbar background
          |
          | (mainViewController)
          |
      UICompositeView : TPMultilayout
                  |
                  |---> view  |--> statusBar
                              |
                              |--> contentView
                              |
                              |--> tabBar

When the application is started, the phoneMainView gets asked to transition to the Dialer view or the Assistant view. PhoneMainView exposes the -changeCurrentView: method, which will setup its Any Linphone view is actually presented in the UICompositeView, with or without a statusBar and tabBar.

The UICompositeView consists of 3 areas laid out vertically. From top to bottom: StatusBar, Content and TabBar. The TabBar is usually the UIMainBar, which is used as a navigation controller: clicking on each of the buttons will trigger a transition to another "view".
