If this is your first attempt at building an iOS app, you should read tech note TNMC0002 first.

At some point during the development of your iOS apps you are going to want to change the name and appearance away from the default Omnis app. This just requires a few simple changes to your clientbuild project before building your new, customized app.

Changing the Identifier:
Each app must have a unique Identifier. An app is identified by its Identifier rather than its name.

Double-click on the target for which you are building to open its Info page, and navigate to the Properties pane. Here you will see the Identifier property – change this to a unique value. The convention is to use a reverse domain name format. E.g: com.omnissoftware.MyApp

If you are updating an existing app, you may also want to increment the Version number here. This way it will be recognized as a newer version, and syncing with iTunes will update older versions of the app on your devices.

Changing the Name:
There are two points where you should change the name:

1) Product Name:
This will be the actual name of your app. Your app will be identified by this in iTunes and internally on the device. If your app adds an entry to the Settings, this name will identify it there.
• In the target’s Info -> Build properties, change the Product Name value.

2) Display Name:
This will be the name the user will see for the app on their device, and will be how the bundle itself is named. The executable within the bundle will be named according to Product Name.
• Open the InfoPlist.strings file, and change the value of CFBundleDisplayName.

Bundle Version Info:
You can change the bundle’s version information, as is seen in the finder, by again opening InfoPlist.strings and editing:
CFBundleGetInfoString – this is displayed as the Version when the bundle’s Get Info is selected in the finder.
CFBundleShortVersionString – this is displayed as the version in the finder’s Preview pane.

Changing the Icons:
The project builds several icons into the app, used to display in different circumstances on the different devices.
These are:
Icon.png (57x57) – App icon displayed on iPhone & iPod Touch
Icon@2x.png (114x114) – App Icon displayed on iPhone4
Icon-72.png (72x72) - App icon displayed on iPad
Icon-Small.png (29x29) – Settings and search results icons on iPhone & iPod Touch, Settings Icon on iPad
Icon-Small@2x.png (58x58) - Settings and search results icons on iPhone4
Icon-Small-50.png (50x50) - Search results icon on iPad

These can be found in the resourcesx folder of your project.
Edit these to your liking, and update. Note that these names should not be changed.

Open the InfoPlist.strings file and check whether it contains a CFBundleIconFile Key and value.
If it does, delete the whole key and value, and save the file. Otherwise this will override your Icon.png.

Changing the Loading Screens:
When your iOS app opens, it briefly shows a splash screen. To change this image you need to alter Default.png (for iPhone/iPod Touch) and Default-Portrait.png (for iPad).
While the app is communicating with, or waiting for a response from the server, the omnislarge.png Icon is faded into view. Again, it’s just a matter of editing this image to personalize this to your application.
The names of these images are hard-coded into the client, so these should not be changed.

iTunes Icons:
In order to display images for your app in iTunes, your project must include a 512x512 PNG image named iTunesArtwork.
If it already exists in your project you can just update that. Otherwise you need to create one and add it to your project by right-clicking the Resources folder, and Selecting Add->Existing Files... and browse to your image. In the window that appears, select all of the targets you wish to add the artwork for.
You must now delete any file extension from the reference name, so that the project lists it in its Resources as iTunesArtwork.
