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.

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= 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 crashlytics

We've integrated Crashlytics 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_CRASHLYTICS=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".
