ios - I think i have done some mistake in allocating segmentcontrol..i am getting an error [unrecognized selector sent to instance] -

- 

    segcontrol = [[uisegmentedcontrol alloc] initwithitems:[nsarray arraywithobjects:@"mind", @"munches", nil]];     segcontrol.frame=cgrectmake(cgrectgetwidth(self.view.frame)/4.5, self.view.frame.size.height/4, cgrectgetwidth(self.view.frame)/1.8, cgrectgetheight(self.view.frame)/12);     [segcontrol addtarget:segcontrol action:@selector(segtap:) forcontrolevents:uicontroleventvaluechanged];     [segcontrol setselectedsegmentindex:0];     [segcontrol settintcolor:[uicolor bluecolor]];     segcontrol.layer.cornerradius=5;     [self.view addsubview:segcontrol];   -(void)segtap:(id)sender{     if (segcontrol.selectedsegmentindex==0) {          self.view.backgroundcolor=[uicolor bluecolor];       }else if (segcontrol.selectedsegmentindex==1){          self.view.backgroundcolor=[uicolor redcolor];       }  }

you adding segmentcontrol object segcontrol target segment action. rather object self should added target. change code below , go.

[segcontrol addtarget:self action:@selector(segtap:) forcontrolevents:uicontroleventvaluechanged];
