In iOS 10.3 Apple added API for alternating icon. I need to change app icon to icon generated in a runtime. Is there a way to generate CFBundleIcon in a runtime so I could make icon change?

    No, you can only select from one of the icons that are included with your original bundle. – Paulw11 Apr 15 '17 at 12:15

Make changes in info plist:-

<key>CFBundleIcons</key>
<dict>
    <key>CFBundleAlternateIcons</key>
    <dict>
        <key>ALTERNATE_APP_ICON_NAME</key>
        <dict>
            <key>CFBundleIconFiles</key>
            <array>
                <string>ALTERNATE_APP_ICON_NAME</string>
            </array>
            <key>UIPrerenderedIcon</key>
            <false/>
        </dict>
    </dict>
    <key>CFBundlePrimaryIcon</key>
    <dict>
        <key>CFBundleIconFiles</key>
        <array>
            <string>AppIcon60x60</string>
        </array>
    </dict>
</dict>

Once you made changes in info plist. You need to add following code:

Objective c:- 

[[UIApplicationsharedApplication] setAlternateIconName:@"ALTERNATE_APP_ICON_NAME"completionHandler:^(NSError * _Nullable error) {
        NSLog(@"Error...");
    }];

Swift:

if UIApplication.shared.supportsAlternateIcons{
    UIApplication.shared.setAlternateIconName("alternater2", completionHandler: { (error) in
        print(error ?? "")
    })

}

  • This doesn't solve OP's problem. They are specifically asking about setting an icon created dynamically (not in the app's bundle). This code cannot do that, and there's no way to change the app icon to an un-bundled one. – Andy Ibanez Feb 21 '20 at 21:14
