Dynamic iPhone App Icons?

The calendar application does this ... How can I change the application icon based on the saved information from the iPod or iPod settings?

EDIT: Today I realized that you can access packages through sdk. (At least read access) If I had a graphical API (possibly OpenGL), I could change this icon. Operation:

  • get the .png icon from the package.
  • change it
  • save it as a set.

It makes sense?

Unfortunately, you cannot use the SDK (which, of course, Apple is not limited using the Calendar application) - you can make icons, but the image is always static.

As a note, the Apple Calendar app is actually hardcoded to display a view by icon. Place it to the left of the first page and drag it into SpotLight, you will notice that the text disappears in different ways.

In response to your editing: no, you cannot modify any files inside your package; your application is isolated to have write access only in its documents, caches and temporary directories.

This is possible in the new iOS 10.3 update (beta), but you will need to specify each icon in the info.plist file.

func setAlternateIconName(_ alternateIconName: String?, completionHandler: ((Error?) -> Void)? = nil)
