How to copy a font programmatically to /System/Library/Fonts/?

Question

I want to copy a font programmatically to the location /System/Library/Fonts/. I used the following coding to do this

NSFileManager *fileManager=[NSFileManager defaultManager];
[fileManager copyItemAtPath:sourcePath toPath:@/System/Library/Fonts error:&error];

For this I am getting the error..

Error Domain=NSPOSIXErrorDomain Code=13 UserInfo=0x4193e0 "The operation couldn’t be completed. Permission denied"   

If I copy the font manually it ask the password first and then it copies to the location. But If I done this programmatically means it is not asking for the password. How can I Implement this feature?
