Dynamic Icon Change for iphone

Question

My question is also same that others asked before.

I found that once you set the Icon for the Application we can\'t change the Application

Answer 1

iOS 10.3+

There is a method called setAlternateIconName: which is introduced in iOS 10.3, through which you can change the app's icon, however these icons should be predefined. It means that the icons should be added to the app's bundle and referenced in the info.plist.

Example:

A typical info.plist looks like:

CFBundleIcons

    CFBundleAlternateIcons
    
        alternate_icon_name
        
            CFBundleIconFiles
            
                alternate_icon_file
            
            UIPrerenderedIcon
            
        
        CFBundlePrimaryIcon
        
            CFBundleIconFiles
            
                default_icon_file
            
            UIPrerenderedIcon
            
        
    

Implement the code like:

Objective C:

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

Swift 3:

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

Before iOS 10.3

You cannot change the icon file dynamically, because the icon file name is stored on the application plist.

.

You cannot change the application plist dynamically, because it is stored on the application bundle which is readonly.

So your requirement is not possible.
