iOS 步数获取

CMPedometer获取步数，获取的步数用户不能进行修改

第一步：配置info.plist里边的获取运动权限

<key>NSMotionUsageDescription</key>
<string>请允许使用运动健康</string>

第二步：引入头文件 #import <CoreMotion/CoreMotion.h>

#import <CoreMotion/CoreMotion.h>

@property (nonatomic, strong) CMPedometer * pedometer;
 第三步：获取步数

// 获取步数
-(void)getHealthStep
{
    if ([CMPedometer isStepCountingAvailable]) {
        _pedometer = [[CMPedometer alloc] init];
            
        NSDateFormatter *df = [[NSDateFormatter alloc] init];
        [df setDateFormat:@"yyyy-MM-dd"];
        NSString *yestr = [df stringFromDate:[NSDate date]];
        [df setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
        //今天0点时间
        NSDate *d = [df dateFromString:[NSString stringWithFormat:@"%@ 00:00:00", yestr]];
        //查询0点到当前时间的数据
        [_pedometer queryPedometerDataFromDate:d toDate:[NSDate dateWithTimeIntervalSinceNow:0] withHandler:^(CMPedometerData * _Nullable pedometerData, NSError * _Nullable error) {

            if (error) {
                NSLog(@"error ===%@", error);
            }
            else {
                NSLog(@"步数====%@", pedometerData.numberOfSteps);
                NSLog(@"距离====%@", pedometerData.distance);
            }
        }];
    }
    else {
        NSLog(@"记步功能不可用");
    }
}
