The name of an app we are developing is longer than can fit under the icon on the home screen, but it looks fine everywhere else it appears in the UI (like when a popup appears asking you if you want to delete it, in the settings app, etc.).
Is there any way to specify a different string for these different places?
Except for localized application names, I'm not aware of any option to specify different application names for different contexts.
You can specify two different bundle names in your Info.plist:
CFBundleDisplayName (String) specifies the display name of the bundle. If you support localized names for your bundle, include this key in both your information property list file and in the InfoPlist.strings files of your language subdirectories. If you localize this key, you should also include a localized version of the CFBundleName key.
CFBundleName (String) identifies the short name of the bundle. This name should be less than 16 characters long and be suitable for displaying in the menu bar and the application’s Info window. You can include this key in the InfoPlist.strings file of an appropriate .lproj subdirectory to provide localized values for it. If you localize this key, you should also include the key “CFBundleDisplayName.”
In Xcode these show up as "Bundle display name" and "Bundle name" respectively.
So just change the value of Bundle name to a shortened form and see if the dashboard uses that instead of the longer Bundle display name
