ios - CMStepCounter not providing step count -

i'm trying explore coremotion , i'm trying use cmstepcounter class step counts. here how implemented view controller stepcounts

@interface viewcontroller ()  @property (weak, nonatomic) iboutlet uilabel *stepscountinglabel;   @property (nonatomic, strong) cmstepcounter *cmstepcounter; @property (nonatomic, strong) nsoperationqueue *operationqueue;  @end  @implementation viewcontroller  - (nsoperationqueue *)operationqueue {     if (_operationqueue == nil)     {         _operationqueue = [nsoperationqueue new];     }     return _operationqueue; }  - (void)viewdidload {     [super viewdidload];      if ([cmstepcounter isstepcountingavailable])     {         self.cmstepcounter = [[cmstepcounter alloc] init];         [self.cmstepcounter startstepcountingupdatestoqueue:self.operationqueue updateon:1 withhandler:^(nsinteger numberofsteps, nsdate *timestamp, nserror *error)          {              [[nsoperationqueue mainqueue] addoperationwithblock:^{                  [self updatestepcounterlabelwithstepcounter:numberofsteps];              }];          }];     }     else     {         self.stepscountinglabel.text = @"no step counting available";     } }  - (void)updatestepcounterlabelwithstepcounter:(nsinteger)countedsteps {     self.stepscountinglabel.text = [nsstring stringwithformat:@"%ld", (long)countedsteps]; } 

but when walk carrying device, i'm not getting update when shake device gives me random numberofsteps count. please let me know if i'm missing out something.

try below method. think work .call startstepcalculations method viewdidload..i calculating steps 1 day.

- (void)startstepcalculations {  if (!self.stepcounter) {     self.stepcounter = [[cmstepcounter alloc] init];   }   if (![cmstepcounter isstepcountingavailable]) {     return;   }  nscalendar *cal = [nscalendar currentcalendar];   nsdatecomponents *components = [cal components:(nshourcalendarunit |                                                   nsminutecalendarunit |                                               nssecondcalendarunit)                                     fromdate:[[nsdate alloc] init]];     [components sethour:-[components hour]];    [components setminute:-[components minute]];    [components setsecond:-[components second]];     nsdate *start = [cal datebyaddingcomponents:components todate:[[nsdate alloc] init] options:0];    [components sethour:+24];   [components setminute:0];   [components setsecond:0];   nsdate *end = [cal datebyaddingcomponents:components todate:start options:0];    nsoperationqueue *queue = [nsoperationqueue mainqueue];   [self.stepcounter querystepcountstartingfrom:start                                         to:end                                    toqueue:queue                                withhandler:^(nsinteger numberofsteps, nserror *error) {    if (error) {      nslog(@"error : %@",error.localizeddescription);      return;    }    self.steps = numberofsteps;    [[uiapplication sharedapplication] setapplicationiconbadgenumber:self.steps];    [self beginmonitoringfornewsteps];   }]; }    - (void)beginmonitoringfornewsteps {   if (!self.stepcounter) {    self.stepcounter = [[cmstepcounter alloc] init];   }  nsoperationqueue *queue = [nsoperationqueue mainqueue];   [self.stepcounter startstepcountingupdatestoqueue:queue                                        updateon:1                                     withhandler:^(nsinteger numberofsteps, nsdate *timestamp, nserror *error) { // calculate total steps (today + new)    self.steps += (int)numberofsteps;  //todo badge number should 1000 max      [[uiapplication sharedapplication] setapplicationiconbadgenumber:self.steps];     }]; } 

let me know working or not.

happy coding!!!
