CMStepCount类在IOS8已经不推荐使用了,IOS8推荐使用CMPedometer类来处理用户健康和运动信息.下面是一个小小的demo来演示下,如何使用它,以及一些注意事项.

#import "ViewController.h" #import <CoreMotion/CoreMotion.h> @interface ViewController () @property (weak, nonatomic) IBOutlet UILabel *stepLabel; @property(nonatomic,strong) CMPedometer *stepter; @property (weak, nonatomic) IBOutlet UILabel *totalLabel; @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; if(![CMPedometer isStepCountingAvailable]) { NSLog(@"计步器不可用"); return; } _stepter =[[CMPedometer alloc]init]; NSTimeInterval secondsPerDay =24*60*60; NSDate *date =[NSDate date]; NSDate *yesterDay =[date dateByAddingTimeInterval:-secondsPerDay]; [_stepter startPedometerUpdatesFromDate:yesterDay withHandler:^(CMPedometerData * _Nullable pedometerData, NSError * _Nullable error) { if(error) { NSLog(@"error ==%@",error); }else { NSNumber *steps =pedometerData.numberOfSteps; NSNumber *distance =pedometerData.distance; NSDictionary *dic =@{ @"steps":steps, @"distance":distance }; NSLog(@"过去一天你一共走了%@步,一共%@米",steps,distance); [self performSelectorOnMainThread:@selector(refreshUI:) withObject:dic waitUntilDone:NO]; } }]; } -(void)refreshUI:(NSDictionary *)dic { NSNumber *distance =dic[@"distance"]; float meters =[distance floatValue]; self.stepLabel.text =[NSString stringWithFormat:@"%@",dic[@"steps"]]; self.totalLabel.text =[NSString stringWithFormat:@"%.2f",meters]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } @end

此处还有一点需要注意:就是请在info.plist文件中加入你要访问用户健康和运动信息的描述,如下图

运行结果如下:
