-

i have segmentedcontrol button , table view below segmentedcontrol.

in viewdidload method, im fetching values core data , populating array follows,

 nserror *error = nil;     apirequest *apirequest = [[apirequest alloc]init];     [apirequest showpendingdata];         nsmanagedobjectcontext *managedobjectcontext = [self managedobjectcontext];     nsfetchrequest *fetchrequest = [nsfetchrequest fetchrequestwithentityname:@"pendingshipmentdetails"];     self.devices = [[managedobjectcontext executefetchrequest:fetchrequest error:nil] mutablecopy];     nsentitydescription *entity = [nsentitydescription entityforname:@"pendingshipmentdetails" inmanagedobjectcontext:managedobjectcontext];     [fetchrequest setentity:entity];     nsarray *fetchedobjects = [managedobjectcontext executefetchrequest:fetchrequest error:&error];     shipmentreferencenumberarray = [[nsmutablearray alloc]init];      (nsmanagedobjectcontext * info in fetchedobjects)      {                 [shipmentreferencenumberarray addobject:[info valueforkey:@"shipmentno"]];      }

in handleselection method, im handling button clicks follow

- (void)handleselection:(id)sender {     uisegmentedcontrol *segmentcontrol = (uisegmentedcontrol *) sender;     nsinteger selectedsegment = segmentcontrol.selectedsegmentindex;      if (selectedsegment == 0)     {         //toggle correct view visible         [self.myorderstableview sethidden:no];         [self.completedorderstableview sethidden:yes];         nslog(@"pending");     }     else     {         //toggle correct view visible         [self.completedorderstableview sethidden:no];         [self.myorderstableview sethidden:yes];         [self.devices removeallobjects];         nserror *error = nil;         apirequest *apirequest = [[apirequest alloc]init];         [apirequest showcompleteddata];          nsmanagedobjectcontext *managedobjectcontext = [self managedobjectcontext];         nsfetchrequest *fetchrequest = [nsfetchrequest fetchrequestwithentityname:@"completedshipmentdetails"];         self.devices = [[managedobjectcontext executefetchrequest:fetchrequest error:nil] mutablecopy];         nsentitydescription *entity = [nsentitydescription entityforname:@"completedshipmentdetails" inmanagedobjectcontext:managedobjectcontext];         [fetchrequest setentity:entity];         nsarray *fetchedobjects = [managedobjectcontext executefetchrequest:fetchrequest error:&error];       } }

now if press segmented control button index 1 im getting following error

  • terminating app due uncaught exception 'nsrangeexception', reason: '* -[__nsarraym objectatindex:]: index 2 beyond bounds [0 .. 1]' * first throw call stack: (0x2867d5f7 0x36347c77 0x28591157 0x15bbd3 0x2bde795d 0x2bde7a1f 0x2bddd141 0x2bbf51cb 0x2bb1f19f 0x2b54af65 0x2b546951 0x2b5467d9 0x2b5461c7 0x2b545fd1 0x2b5989f1 0x2fe5f82f 0x295a71ed 0x286333a5 0x286437f3 0x2864378f 0x28641db1 0x2858eb31 0x2858e943 0x2f952051 0x2bb80f21 0x164195 0x368e3aaf) libc++abi.dylib: terminating uncaught exception of type nsexception (lldb)
