To be quite clear, CFBundleIcons is a dictionary containing the key CFBundleAlternateIcons, which is a dictionary containing the key YourImageName, which is another dictionary containing the icon files and gloss effect settings. Each icon name is another dictionary, which contains the same two keys as CFBundlePrimaryIcon: the CFBundleIconFiles array and the UIPrerenderedIcon boolean.This doesn’t need to be their filename, just however you want to reference each icon in your code. The alternate icons key is also a dictionary, but this time the keys of its children are the names of images you want to use.Yes, that latter setting has been dead since iOS 7 but it still loiters around. The primary icon key itself is a dictionary that lists its icon files ( CFBundleIconFiles), which is an array containing the filenames for your primary icon, and whether iOS should apply gloss effects to it ( UIPrerenderedIcon).CFBundleIcons is a dictionary that defines what your primary icon is ( CFBundlePrimaryIcon) and what your alternate icons are ( CFBundleAlternateIcons).This will reveal the raw XML behind your plist – it might seem like a lot at first, but trust me this is way better than using the GUI for this particular task.ĭefining the icons for your app is done with a very specific set of property list keys and values: Now go to your project navigator, right-click your ist file, and choose Open As > Source Code. are all just regular PNGs, with the being 120x120 and the being 180x180.Remember to use the and naming convention to ensure iOS automatically picks the correct icon for users’ devices.įor this example, we’re using these example icon files: These should be placed loose in your project or in a group, rather than inside an asset catalog. The process behind this is far from optimal, and right now the best thing to do is edit your ist as XML rather than trying to use the built-in property list editor in Xcode.

The actual code to change your app’s icon is trivial, but first there’s some setup work because you must declare all possible icons in your ist file. It also isn’t quite as powerful as you might hope – you can’t recreate the moving hands of the Clock app, for example. IOS gives developers the ability to change their app’s icon programmatically, although it takes a little work to set up.
