CMStepCounter记录的数据并不准确,iOS 8.0下已经过期,CMPedometer返回的结果更为精准,但是有延迟性
示例代码:
#import "ViewController.h"
#import <CoreMotion/CoreMotion.h>
@interface ViewController ()
@property (nonatomic,strong) CMPedometer *pedometer;
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// 1. 创建计步器
self.pedometer = [[CMPedometer alloc]init];
// 2. 开启计步器
[self.pedometer startPedometerUpdatesFromDate:[NSDate date] withHandler:^(CMPedometerData * _Nullable pedometerData, NSError * _Nullable error) {
NSLog(@"%@",pedometerData.numberOfSteps);
}];
}
@end
除了上面的方法获取数据外,还提供了一个方法,可以限定时间内获取计步数据
[self.pedometer queryPedometerDataFromDate:[NSDate date] toDate:[NSDate dateWithTimeIntervalSinceNow:10] withHandler:^(CMPedometerData * _Nullable pedometerData, NSError * _Nullable error) {
NSLog(@"%@",pedometerData.numberOfSteps);
}];
回调中结果返回为一CMPedometerData对象,其中包含属性有:
@property(readonly, nonatomic) NSDate *startDate; 开始时间
@property(readonly, nonatomic) NSDate *endDate; 结束时间
@property(readonly, nonatomic) NSNumber *numberOfSteps; 计步
@property(readonly, nonatomic, nullable) NSNumber *distance; 距离
@property(readonly, nonatomic, nullable) NSNumber *floorsAscended;上了多少台阶
@property(readonly, nonatomic, nullable) NSNumber *floorsDescended;下了多少台阶
@property(readonly, nonatomic, nullable) NSNumber *currentPace;步速 s/m
@property(readonly, nonatomic, nullable) NSNumber *currentCadence;节奏steps/s
