iOS 9 - UICache Programmatically

Question

I'm trying to reload the icon cache after installing an application through LSApplicationWorkspace. The applications install, but I have to execute "uicache" in mobileterminal to reload the springboard cache. Is there a way I could do this programmatically? The application ISN'T running as root by the way.

At the moment, I have code as follows to reload the springboard icon cache but it doesn't work:

remove("/var/mobile/Library/Caches/com.apple.mobile.installation.plist");
remove("/var/mobile/Library/Caches/com.apple.springboard-imagecache-icons");
remove("/var/mobile/Library/Caches/com.apple.springboard-imagecache-icons.plist");
remove("/var/mobile/Library/Caches/com.apple.springboard-imagecache-smallicons");
remove("/var/mobile/Library/Caches/com.apple.springboard-imagecache-smallicons.plist");
remove("/var/mobile/Library/Caches/SpringBoardIconCache");
remove("/var/mobile/Library/Caches/SpringBoardIconCache-small");
remove("/var/mobile/Library/Caches/com.apple.IconsCache");

// find ios 8 version:
NSString *cache_path = @"/var/mobile/Library/Caches/";
NSArray *conts = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:cache_path error:nil];
for (NSString *filefolder in conts) {
    if ([filefolder containsString:@"com.apple.LaunchServices"]) {
        NSString *newpath = [cache_path stringByAppendingPathComponent:filefolder];
        remove([newpath UTF8String]);
    }
}

// build the args list
Class __LSApplicationWorkspace = objc_getClass("LSApplicationWorkspace");
[(LSApplicationWorkspace *)[__LSApplicationWorkspace defaultWorkspace] invalidateIconCache:nil];
[(LSApplicationWorkspace *)[__LSApplicationWorkspace defaultWorkspace] registerApplication:[NSURL fileURLWithPath:bundlePath]];
int didNotify = notify_post("com.apple.mobile.application_installed");
NSLog(@"Did Notify: %i",didNotify);

// remove temp.app:
if ([[NSFileManager defaultManager] fileExistsAtPath:bundlePath]) {
    [[NSFileManager defaultManager] removeItemAtPath:bundlePath error:nil];
}

I found a temporary solution to my question if anyone is interested. I created an extra application (running as root), that was to be installed separately from the original app. I made this application invisible to the user by adding the following to the Info.plist:

<key>SBAppTags</key>
  <array>
     <string>hidden</string>
  </array>

And used URL Schemes to call the "Reload" function.

Although another option could have been to create a LaunchDaemon or a MobileSubstrate extension. I couldn't find a way of reloading the cache as a "mobile" user though.
