第一种：CMPedometer
#import "ViewController.h"
#import <CoreMotion/CoreMotion.h>
@interface ViewController ()
@property(nonatomic,strong)CMPedometer *pedometer;
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
_pedometer = [[CMPedometer alloc]init];
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDate *now = [NSDate date];
NSDateComponents *components = [calendar components:NSCalendarUnitYear|NSCalendarUnitMonth|NSCalendarUnitDay fromDate:now];
// 开始日期
NSDate *startDate = [calendar dateFromComponents:components];
// 结束日期
NSDate *endDate = [calendar dateByAddingUnit:NSCalendarUnitDay value:1 toDate:startDate options:0];
//判断记步功能
if ([CMPedometer isStepCountingAvailable]) {
[_pedometer queryPedometerDataFromDate:startDate toDate:endDate 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");
}
}
可能会出现的错误：
1、Domain=CMErrorDomain Code=103，将CMPedometer对象作为全局变量就可以了；
2、Domain=CMErrorDomain Code=105，用户拒绝访问步数了，手动打开权限就可以，若还是有问题，删掉app重新运行；

调用步数方法：
HealthKitManager *manage = [HealthKitManager shareInstance];
[manage authorizeHealthKit:^(BOOL success, NSError *error) {
if (success) {
[manage getStepCount:^(double value, NSError *error) {
DLOG(@"1count-->%.0f", value);
DLOG(@"1error-->%@", error.localizedDescription);
}];
}
}];
