How do I build an iOS application?

This lesson will show you how to use LiveCode to create, test and deploy an iPhone application.

Before you can build iPhone applications, you'll need to have Xcode installed on your machine. This is currently available from the Mac App Store or you can register as an iPhone developer and get older SDKs here: For more information on how to get started with iPhone development see this lesson: How Do I Become An iPhone Developer.

If you are creating an App from scratch, then is is good practice to set your stack size to something that is workable for your display. LiveCodes resolution independence features make it easy to resize any size stack to any screen resolution. More information on this feature is available here-

Some example device resolutions that you may wish to set your stack dimensions to are

iPhone 3G and older: 480px by 320px

iPhone 4: 960px by 640px.

iPad: 1024px by 768px

iPad Retina- 2048px by 1536px

For this example we've used the sheep herder application we made to demonstrate LiveCode in action. You can download the source here:

And watch us make it here:

Open the standalone builder and configure deployment options

Open the standalone application setting from the File menu and go to the iOS tab. Here you'll be able to configure the Apps basic settings and also set a wide range of other more fine grained options (Plist options for those more seasoned developers).

You must select "Build for iOS" (1) in order to enable the Simulator and building iOS standalones.

You must also select the device profile(2) you created when you registered with Apple. (if deploying to a test device)

Testing with the simulator

When you install the Xcode on your machine, you'll get an iOS simulator application, which allows you to debug your iOS apps easier than using a real device. Once you have selected the build for iOS option in the standalone builder and selected a simulator from the development menu,you'll see the "Test" button has now become active. Clicking this will launch the simulator*.

NB Xcode must  be linked to your version of LiveCode via LiveCodes Mobile Support Preferences. This option is available from "LiveCode"--->"Preferences"---->"Mobile Support"

An example video of this process can be found here-

Creating the deployment bundle

Creating the deployment bundle

Once you have registered appropriately as an iPhone developer and setup your certificate and obtained a provisioning profile, you can deploy your application onto a real iPhone, iPad or iPod touch. To do this, simply choose your provisioning profile from the drop-down list in the standalone application setting screen(like discussed above), and then select "Save as Standalone Application..." from the file menu.

For more information on registering as an iPhone developer see the lesson here: How Do I Become An iPhone Developer.

N.B. if you recieve a "linking for armv7 failed with g++: failed to exec /Applications/; No such file or directory" error message when building this generally means the required command line tools have not been automatically set in Xcode. You can resolve this by opening Xcodes preferences, navigating to "Locations" and select the avaible command line tools from the drop down menu. If none are present, you may need to download them from the "Downloads" tab

Putting the App onto your device

1) Open Xcode

2) In the 'Window' menu select 3) "Devices"

4) Select your connected iOS device

5) Drag standalone app to "Installed Apps" section of device window

Your app should now be on your device!
