1. Introduction
-----------------------------------------------------------------------------

This is a platform port of Kodi for the Apple iOS operating system. 
The current build system supports Xcode 3.2.6, 4.3.x, 5.x.x, 6.0.1, 6.1.0 with iOS SDK 4.3/5.1/6/7/8/8.1
There are two ways to build Kodi for Mac.

1) command-line or
2) Xcode.

Generally, Xcode is the easiest as it presents the build system in a GUI environment.
The command-line build is still under development.

Kodi for iOS is composed of a main binary with numerous dynamic libraries and
codecs that support a multitude of music and video formats.

NOTE TO NEW OS X USERS: All lines that are prefixed with the '$' character are
commands that need to be typed into a Terminal window. Note that the '$'
character itself should NOT be typed as part of the command.


-----------------------------------------------------------------------------
2. Getting the source code
-----------------------------------------------------------------------------

 $ cd $HOME
 $ git clone git://github.com/xbmc/xbmc.git Kodi
 $ cd Kodi
 $ git submodule update --init addons/skin.re-touched

-----------------------------------------------------------------------------
3.0 Install Xcode
-----------------------------------------------------------------------------
See point 3.0a below for an updated list of supported Xcode/osx constellations!!!

Install latest Xcode (6.1.0 as of the writing). You can download it from 

1. The MacOSX AppStore (Xcode). 

If you are using XCode 4.3.x you also need to install the "Command Line Tools". To do so
after installing Xcode you have to go to "Xcode->Preferences->Downloads" and install the
package "Command Line Tools". In later XCode versions as of 5.x those will be installed
automatically once they are invoked from the cmdline.

Xcode 3.2.6 only runs on 10.6.x (Snow Leopard). 
Xcode 4.3.x only runs on 10.7.x (Lion).
Xcode 5.x.x only runs on 10.8.x and later.
Xcode 6.0.1 only runs on 10.9.4 and later.
Xcode 6.1.0 only runs on 10.9.5 and later.

The preferred iOS SDK Version is 4.3 (when using Xcode 3.2.6) or 5.1 (when using
Xcode 4.3.x) or 7.x (when using Xcode 5.x.x) or 8.x (when using Xcode 6.x.x)

-----------------------------------------------------------------------------
3.0a Supported Xcode and OSX constellations
-----------------------------------------------------------------------------
As far as we know the compilation for ios and atv2 should work with the following
constellations of Xcode and osx versions (to be updated once we know more):

1. XCode 3.2.6 against iOS SDK 4.3 on 10.6.x (Snow Leopard)
2. XCode 4.3.x against iOS SDK 4.3 and 5.1 on 10.7.x (Lion)
3. XCode 4.6 against iOS SDK 4.3, 5.1 and 6.1 on 10.7.x (Lion) and 10.8.x (ML)
3.a Building against iOS SDK 6.0 will only allow to run on targets with iOS 5.1 and below.
    There is no support for devices running iOS 6.0 for now!
4. Xcode 5.1.1 against iOS SDK 7.0 and 7.1 on 10.9.x (Mavericks)
5. Xcode 6.0.1 against iOS SDK 8.0 on 10.9.x (Mavericks)
6. Xcode 6.1.0 against iOS SDK 8.1 on 10.10.x (Yosemite)

-----------------------------------------------------------------------------
3.1 Install Cross libs and runtime environment
-----------------------------------------------------------------------------

 The following commands will build using the latest iOS SDK found on your 
 system.

 $ cd $HOME/Kodi
 $ cd tools/depends
 $ ./bootstrap
 $ ./configure --host=arm-apple-darwin
 $ make

 NOTE: You can speedup compilation on multicore systems by doing 
 "make -j<number of cores>" instead of "make". For a dualcore this would read:
 "make -j2"

 ADVANCED developers only! If you want to specify an iOS SDK version (if
 multiple versions are installed) - then append it to the configure line
 above (example below would use iOS SDK 6.0):

 $ ./configure --host=arm-apple-darwin --with-sdk=6.0

 Ensure that you also adapt the xcode project to use this SDK version or
 if building via cmdline the SDKROOT parameter of the xcodebuild command.

-----------------------------------------------------------------------------
4. How to compile
-----------------------------------------------------------------------------
Both Xcode and Terminal compilation require that build environment be setup
from the step 3.1.

 $ cd $HOME/Kodi
 $ make -C tools/depends/target/xbmc
 $ make clean
 $ make xcode_depends

-----------------------------------------------------------------------------
4.1 Using Xcode
-----------------------------------------------------------------------------
Start XCode and open the Kodi project (Kodi.xcodeproj)
located in $HOME/Kodi.

There are two relevant build configurations : Release and Debug. Compile always for device
end not simulator and select the wanted target (either Kodi-iOS or Kodi-ATV2)

If you have selected a specific iOS SDK Version in step 3.1 then you might need 
to adapt the active target to use the same iOS SDK version. Else build will fail 
(you will see alot of errors with at least non-found boost/shared_ptr.hpp).

On XCode5.x apple removed the gcc compiler. On those XCode versions you need to switch the compiler
of the ATV2 project manually to "default/clang".

-----------------------------------------------------------------------------
4.2 Using Terminal (command-line)
-----------------------------------------------------------------------------

 $ cd $HOME/Kodi
 $ xcodebuild -project Kodi.xcodeproj -target Kodi-iOS -configuration Release build \
   ONLY_ACTIVE_ARCH=YES ARCHS=armv7 VALID_ARCHS=armv7 IPHONEOS_DEPLOYMENT_TARGET=4.3 \
   SDKROOT=iphoneos4.3

or

 $ xcodebuild -project Kodi.xcodeproj -target Kodi-ATV2 -configuration Release build \
  ONLY_ACTIVE_ARCH=YES ARCHS=armv7 VALID_ARCHS=armv7 IPHONEOS_DEPLOYMENT_TARGET=4.3 \
  SDKROOT=iphoneos4.3
 
 Make sure to set SDKROOT to the iOS SDK you want to use. This should be the same
 you used on point 3.1!

-----------------------------------------------------------------------------
5. Packaging
-----------------------------------------------------------------------------

This section describes how to package Kodi in a deb image for
distribution.

  1. build Kodi for iOS or ATV2 from XCode so that the application bundle is 
     correctly updated.

  2. 
   $ cd tools/darwin/packaging/atv2
   or
   $ cd tools/darwin/packaging/ios

  3. $ chmod +x ./mkdeb-atv2.sh && ./mkdeb-atv2.sh release
     or
     $ chmod +x ./mkdeb-ios.sh && ./mkdeb-ios.sh release
     
  4. Use release or debug - you have to be sure that you build the corresponding 
     version before.
  
  5. The resulting deb file can be copied to the iOS/ATV2 via ssh/scp and then be 
     installed manually. For this you need to ssh into the iOS/ATV2 and do:
     $ dpkg -i <name of the deb file>

-----------------------------------------------------------------------------
6. Gesture Handling on iPad/iPhone/iPod touch
-----------------------------------------------------------------------------

 - double finger swipe left                   -> back
 - double finger tap/single finger long tap   -> right mouse
 - single finger tap                          -> left mouse
 - panning, and flicking                      -> for navigating in lists
 - dragging                                   -> for scrollbars and sliders
 - zoom gesture                               -> in the pictureviewer

-----------------------------------------------------------------------------
7. Remote control on ATV2
-----------------------------------------------------------------------------

 - Select             -> like enter/left click - OK button on other remotes (during playback its pause by defaul)
 - Select long press  -> During playback show the overlay
 - Cursor keys        -> for moving around and selecting controls
 - Menu               -> back
 - Menu long press    -> context menu
 
------------------------------------------------------------------------------
8. Usage/Development on un-jailbroken devices (only interesting for official apple developers!)
------------------------------------------------------------------------------

If you are a developer with an official apple code signing identity you can deploy Kodi
via xcode to work on it on non-jailbroken devices. For this to happen you just need to alter the
Xcode project by setting your codesign identity. Be sure to not just select the "iPhone Developer" shortcut
but instead select your full identity "iPhone Developer: your name (your id)" (this is important else our sign
script won't detect a real sign identity). After that the last buildstep in our support script
will do a full sign of all binaries and the bundle with the given identity (all *.viz, *.pvr, *.so files
Xcode doesn't know anything about). This should allow you to deploy Kodi to all non-jailbroken devices
which you can deploy normal apps to. In that case (Kodi will be sandboxed like any other app) - all Kodi
files are then located in the sandboxed "Documents" folder and can be easily accessed via iTunes file
sharing.
Keep in mind that no hardware acceleration will be possible without jailbreaking when using iOS < Version 8.
