編程開啟iOS emoji

emoji是日本人開發的一字符編碼集，在iOS中集成了該字符集。 可以通過編程的方式激活emoji。

首先判斷是否支持emoji：

1. - (BOOL)supportEmoji
2. {
3. BOOL hasEmoji = NO;
4. #define kPreferencesPlistPath @"/private/var/mobile/Library/Preferences/com.apple.Preferences.plist"
5. NSDictionary *plistDict = [[NSDictionary alloc] initWithContentsOfFile:kPreferencesPlistPath];
6. NSNumber *emojiValue = [plistDict objectForKey:@"KeyboardEmojiEverywhere"];
7. if (emojiValue) //value might not exist yet
8. hasEmoji = YES;
9. else
10. hasEmoji = NO;
11. [plistDict release];
13. return hasEmoji;
14. }

1. - (void)valueControl:(BOOL)open
2. {
4. #define kPreferencesPlistPath @"/private/var/mobile/Library/Preferences/com.apple.Preferences.plist"
5. NSMutableDictionary* plistDict = [[NSMutableDictionary alloc] initWithContentsOfFile:kPreferencesPlistPath];
6. [plistDict setValue:[NSNumber numberWithBool:open] forKey:@"KeyboardEmojiEverywhere"];
7. [plistDict writeToFile:kPreferencesPlistPath atomically:NO];
8. [plistDict release];
9. }

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