ios - uisplitviewcontroller: passing selected row from master to detail -

it's couple of days i've been struggling uisplitviewcontrollers, here's problem: have master view declared follows

#import <uikit/uikit.h> #import "detailviewcontroller.h"  @class detailviewcontroller; @interface masterviewcontroller : uitableviewcontroller {     nsmutablearray *title, *subtitle;     unsigned int quantity; }  @property (strong, nonatomic) detailviewcontroller *detailviewcontroller; @end 

in master's .m file works correctly (i'm able populate table sqlite db , show contents in rows). when comes select 1 row , populate detailed view on right side nothing happens. here row selection:

- (void)tableview:(uitableview *)tableview didselectrowatindexpath:(nsindexpath *)indexpath {     myobject itemfromdb;     /*       ... db stuff here ...      */      self.detailviewcontroller.detailitem = itemfromdb;   } 

here's detailviewcontroller implementation:

@interface detailviewcontroller : uiviewcontroller <uisplitviewcontrollerdelegate> @property (strong, nonatomic) myobject *detailitem; @property (weak, nonatomic) iboutlet uilabel *name, *phone; @end 

and detail's .m:

#import "detailviewcontroller.h" @interface detailviewcontroller () - (void)configureview; @end  @implementation detailviewcontroller  - (void)setdetailitem:(myobject *)newitem {     if (_detailitem != newitem) {         _detailitem = newitem;         [self configureview];     } }  - (void)configureview {     if (self.detailitem) {         self.name.text = [self.detailitem name];         self.phone.text = [self.detailitem phone];     } }  - (void)viewdidload {     [super viewdidload];     [self configureview]; }  - (void)didreceivememorywarning {     [super didreceivememorywarning]; }  

in simple words: detail isn't noticing changes after selection of row. help?

you never defined self.detailviewcontroller. should this:

self.detailviewcontroller = self.splitviewcontroller.viewcontrollers[1];
