編程開啟iOS emoji

emoji是日本人(建議不要買日本的產品，支援國產，恨死日本男人了，哈哈)開發的一字元編碼集，在iOS中整合了該字元集。 可以通過編程的方式啟用emoji。

首先判斷是否支援emoji：

- (BOOL)supportEmoji{BOOL hasEmoji = NO;#define kPreferencesPlistPath @"/private/var/mobile/Library/Preferences/com.apple.Preferences.plist"NSDictionary *plistDict = [[NSDictionary alloc] initWithContentsOfFile:kPreferencesPlistPath];NSNumber *emojiValue = [plistDict objectForKey:@"KeyboardEmojiEverywhere"];if (emojiValue)//value might not exist yethasEmoji = YES;elsehasEmoji = NO;[plistDict release];return hasEmoji;}

開啟或關閉該功能：

- (void)valueControl:(BOOL)open{#define kPreferencesPlistPath @"/private/var/mobile/Library/Preferences/com.apple.Preferences.plist"NSMutableDictionary* plistDict = [[NSMutableDictionary alloc] initWithContentsOfFile:kPreferencesPlistPath];[plistDict setValue:[NSNumber numberWithBool:open] forKey:@"KeyboardEmojiEverywhere"];[plistDict writeToFile:kPreferencesPlistPath atomically:NO];[plistDict release];}

如果你想看效果，除了調用上面方法：[self valueControl:YES]外，還得開啟emoji鍵盤，方法如下：

Go to Settings > General > International > Keyboards > Japanese and enable the Emoji keyboard.
