How to get the current application icon in ios

Question

Is there a way to get the current application icon in a cocoa-touch app? Thank you.

Answer 1

This is how the icons is set inside the info.plist,

//try doing NSLog(@"%@",[[NSBundle mainBundle] infoDictionary]);

 CFBundleIcons =     {
        CFBundlePrimaryIcon =         {
            CFBundleIconFiles =             (
                "icon.png",//App icon added by you
                "icon@2x.png"//App icon in retina added by you
            );
            UIPrerenderedIcon = 1;
        };
    };

If you want to get the app icon use below code:

UIImage *appIcon = [UIImage imageNamed: [[[[[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleIcons"] objectForKey:@"CFBundlePrimaryIcon"] objectForKey:@"CFBundleIconFiles"] objectAtIndex:0]];

P.S: UIImage automatically picks the suitable icon for retina display.

I hope it helps!!

Works for Swift 4.1 and extending it for Bundle.

extension Bundle {
    public var icon: UIImage? {
        if let icons = infoDictionary?["CFBundleIcons"] as? [String: Any],
            let primaryIcon = icons["CFBundlePrimaryIcon"] as? [String: Any],
            let iconFiles = primaryIcon["CFBundleIconFiles"] as? [String],
            let lastIcon = iconFiles.last {
            return UIImage(named: lastIcon)
        }
        return nil
    }
}

To use in an app, call Bundle.main.icon.

I based my answer completely on moosgummi's, but returning a UIImage instead.

UIImage *appIcon = [UIImage imageNamed: [[[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleIconFiles"] objectAtIndex:0]];

The UIImage automatically selects the suitable version (normal, @2x, ~ipad, ~ipad@2x or any future suffix). (BTW, don't you just hate this stupid scheme for identifying versions of images? It was just getting out of hand. Thank god for Asset Catalogues!)
