ios - UITextInputMode currentInputMode is deprecated. Suggested replacement? -

in our app, we'd detect current keyboard language. example, if user sets multiple language keyboards under settings->general->keyboard->keyboards, we'd know language they're typing in , notification nsnotificationcenter when changes.

- (void)viewdidload {     [super viewdidload];     nsnotificationcenter *ncenter = [nsnotificationcenter defaultcenter];     [ncenter addobserver:self selector:@selector(languagechanged:) name:uitextinputcurrentinputmodedidchangenotification object:nil];     [self languagechanged:nil]; }  -(void)languagechanged:(nsnotification*)notification {     for(uitextinputmode *mode in [uitextinputmode activeinputmodes])     {         nslog(@"input mode: %@", mode);         nslog(@"input language: %@", mode.primarylanguage);     }     nslog(@"notification: %@", notification);     uitextinputmode *current = [uitextinputmode currentinputmode];     nslog(@"current: %@", current.primarylanguage); } 

what we've discovered code notification fires appropriately when user toggles keyboards using globe icon on keyboard, when iterate uitextinputmodes, appear in same order no (apparent) indication of current 1 unless use now-deprecated [uitextinputmode currentinputmode].

i can't find documentation indicating apple's suggested alternative now-deprecated functionality. there several threads mentioning deprecation, none found solutions. ideas? in advance.

the object notification uitextinputcurrentinputmodedidchangenotification instance of uitextinputmode.

uitextinputmode *currentinputmode = [notification object]; 

also, can active input mode on particular responder:

uitextview *textview = [[uitextview alloc] init]; uitextinputmode *currentinputmode = textview.textinputmode; 

currently on ios 7, textinputmode/notification object nil emoji keyboard. it's unclear if intended behaviour.
