ios - Can't set cell title's text -

i'm writing simple notes app, when seek assign title note.title got error.

-(notez*)createnotewithtitle:(nsstring*)titlenote andtext:(nsstring*)textnote { notez *newnote = [notez new]; if (!_notesarray) { _notesarray = [nsmutablearray new]; } newnote.datecreated = [nsdate new]; newnote.title = [nsstring stringwithformat:@"23"]; newnote.text = [nsstring stringwithformat:@"233"]; [_notesarray addobject:newnote]; homecoming newnote; }

notez.h : #import

@interface notez : nsobject @property nsstring *text; @property nsstring *title; @property nsdate* datecreated; -(notez*)createnotewithtitle:(nsstring*)title andtext:(nsstring*)text; -(void)save; +(instancetype)sharedmanager; -(nsarray*)sortednotes; -(void)removenoteatindex:(nsuinteger)index; @end

note.datecreated ok, note.title , note.text isn't.

they both nsstring...

- (ibaction)addnote:(id)sender { [[notez sharedmanager] createnotewithtitle:@"note title" andtext:@"note text"]; }

since declared title , text properties, reason exception: [notez settitle:]: unrecognized selector sent instance, apparently

i can create guess here. usually, when declaring property, setter , getter method it. way can omit writing these hand if have lot of instance variables on class.

using dot notation equivalent calling setter or getter. in case

newnote.title = [nsstring stringwithformat:@"23"];

is equivalent to:

[newnote settitle:[nsstring stringwithformat:@"23"]];

now, exception suggests setter method: settitle: not exist on object. i'm not sure reason might be, seek explicitly synthesize properties.

therefor, in .m-file add together next lines of code:

@synthesize title; @synthesize text;

not sure if solve issue, hope explanation of properties, getters , setters helps understand little more what's going on.
