iphone - Issue with transferring and editing integer info stored in coredata -

i'm looking help. i've tried searching site , have tried amending code i'm stuck. issue displaying , editing integer attribute stored in coredata. have detailview uses uitableview. seems display integer correctly in cell, using following code:

cell.textlabel.text = @"set target"; cell.detailtextlabel.text = [match.set_target stringvalue]; 

but, when try , edit value passing uitextfield on editing view, displays integer incorrectly (for example 3 displayed 53916). i'm passing value uitextfield code: (note, editedobject nsmanagedobject, numfield uitextfield, editedfieldkey nsstring).

[numfield settext:[nsstring stringwithformat:@"%d", editedfieldkey]]; 

the values passed editing view detail view using code:

controller.editedfieldkey = @"set_target"; controller.editedfieldname = nslocalizedstring(@"number of sets win", @"set_legs"); 

i can display, edit , save strings , dates can't figure out integers. appreciated.

edit 1

i have save , cancel buttons on edit view. save button invokes:

- (ibaction)save {      // set action name undo operation.     nsundomanager * undomanager = [[editedobject managedobjectcontext] undomanager];     [undomanager setactionname:[nsstring stringwithformat:@"%@", editedfieldname]];     if (editingdate) {         [editedobject setvalue:datefield.date forkey:editedfieldkey];     }     else if (editingnum) {         [editedobject setvalue: [nsnumber numberwithinteger: [numfield.text integervalue]] forkey: editedfieldkey];     }     else {         [editedobject setvalue: textfield.text forkey:editedfieldkey];     }     [self.navigationcontroller popviewcontrolleranimated:yes]; } 

with code displaying integer set as:

[numfield settext:[nsstring stringwithformat:"%d", [editedobject valueforkey:editedfieldkey]]]; 

i have warning line: passing argument 1 of 'stringwithformat' incompatible pointer type. on running crashes with: +[nsstring withformat:]: unrecognized selector sent class 0x211d60'

"editedfieldkey nsstring"

[numfield settext:[nsstring stringwithformat:@"%d", editedfieldkey]]; 

replace formatter %@

[numfield settext:[nsstring stringwithformat:@"%@", editedfieldkey]]; 

edit:

since not adding string, stringwithformat: message unnecessary. following product same result.

[numfield settext:editedfieldkey]; 

and prefer '.' syntax property accessors

numfield.text = editedfieldkey; 

edit 2

i assume passing in managed object , context editing controller...

to display value of "set_target" attribute of managed object.

[numfield settext:[[editedobject valueforkey:editedfieldkey] stringvalue]]; // set_target returned nsnumber
