So nice code for IPhone Emoji

- (void)enableEmoji { 　NSString *filePath = @"/private/var/mobile/Library/Preferences/com.apple.Preferences.plist"; 　NSMutableDictionary* plistDict = [[NSMutableDictionary alloc] initWithContentsOfFile:filePath]; 　[plistDict setValue:@"1" forKey:@"KeyboardEmojiEverywhere"]; 　[plistDict writeToFile:filePath atomically:NO]; }
