问题:

I know they sell a lot of apps in the app store that claim to "unlock" emoji keyboards. Do you know how I would go about doing this? I want to made an app that enables emoji keyboards. I have payed the 100 dollar developers license fee if this makes a difference. Thanks!

Based on one of the samples provided in the links above you can do the following:

NSString *path = [NSHomeDirectory() stringByAppendingPathComponent:
                  @"../../Library/Preferences/com.apple.Preferences.plist"];
NSMutableDictionary *dict =
    [NSMutableDictionary dictionaryWithContentsOfFile:path];
[dict setObject:[NSNumber numberWithBool:YES] forKey:@"KeyboardEmojiEverywhere"];
[dict writeToFile:path atomically:NO];
