在ios8中，ios7新增加的计步器CMStepCounter已经过时，而用CMPedometer代替。

具体代码（CMStepCounter）

    if ([CMStepCounterisStepCountingAvailable]) {

    self.stepCounter=[[CMStepCounter alloc]init];

        NSOperationQueue *queue=[[NSOperationQueue alloc]init];

        [self.stepCounter startStepCountingUpdatesToQueue:queue updateOn:5 withHandler:^(NSInteger numberOfSteps, NSDate *_Nonnull timestamp, NSError * _Nullable error) {

            self.stepLabel.text=[NSString stringWithFormat:@"用户已经行走了【%d】步！",numberOfSteps];

        }];

    }

(CMPedometer)

    if ([CMPedometer isStepCountingAvailable]) {

        self.pedometer=[[CMPedometer alloc]init];

        [self.pedometer startPedometerUpdatesFromDate:[NSDate date] withHandler:^(CMPedometerData *_Nullable pedometerData, NSError * _Nullable error) {

            CMPedometerData *data=(CMPedometerData *)pedometerData;

            NSNumber *number=data.numberOfSteps;

            self.stepLabel.text=[NSString stringWithFormat:@"用户已经行走了【%@】步！",number];

        }];

    }
