TextView word count when inputting Chinese and highlighting English input method

Counting words

1, First register monitoring

[[Nsnotificationcenter Defaultcenter] addobserver:self selector: @selector (textvieweditchanged:) name:@ " Uitextviewtextdidchangenotification "Object:_textview";

　　

2. Implement Monitoring method

-(void) textvieweditchanged: (nsnotification *) obj{Uitextview *textfield = (Uitextview *) Obj.object;        NSLog (@ "========%@", Textfield.text);    NSString *tobestring = Textfield.text; NSString *lang = [[Uitextinputmode currentinputmode] primarylanguage]; Keyboard input mode if ([Lang isequaltostring:@ "Zh-hans"]) {//Simplified Chinese input, including simplified pinyin, fitness wubi, simplified handwriting uitextrange *selectedrange = [text        Field Markedtextrange];        Get the highlighted part uitextposition *position = [TextField positionFromPosition:selectedRange.start offset:0]; No highlighted words, word count and limit if (!position) {if (Tobestring.length >) {textField) for typed text                                . Text = [tobestring substringtoindex:10]; [[[Uialertview alloc] initwithtitle:@ "DSFSA" message:@ "msg" Delegate:self cancelbuttontitle:nil otherbuttontitles:@ "                                Sure ", nil) show];            [Self.textview Resignfirstresponder];        }}//With a highlighted string, the text is temporarily not counted and restrictedelse{}}//In addition to the Chinese input method directly to its statistical restrictions, regardless of other languages else{if (Tobestring.length > 10) {                        Textfield.text = [tobestring substringtoindex:10]; [[[Uialertview alloc] initwithtitle:@ "DSFSA" message:@ "msg" Delegate:self cancelbuttontitle:nil otherbuttontitles:@ "        Sure ", nil) show]; }    }    }

　　

3, the final cancellation of the supervisor listener

-(void) dealloc{    [[Nsnotificationcenter Defaultcenter] removeobserver:self name:@ " Uitextviewtextdidchangenotification "Object:_textview";}
