目前公司业务有用到获取Apple-Health里的步数和心率，所以自己初步了解了一下有关于iOS的HealthKit的简单实用
1.target->signing&Capabilities里面点击+capability选择HealthKit如下图所示

添加HealthKit

备注：可以不用勾选Capabilities （1.clinical Healtg Records;2.Background Delivery）
2.info.plist加上隐私权限
NSHealthShareUsageDescription
NSHealthUpdateUsageDescription
3.这个时候会自动生成一个EntitlementsFile
4.这个时候就可以着手代码部分。
新建一个HealthManager类

#import <Foundation/Foundation.h>

NS_ASSUME_NONNULL_BEGIN

//当前健康数据授权的状态
typedef NS_ENUM(NSInteger ,SMHealthAuthorizationStatus){
    SMHealthAuthorizationStatusNotDetermined = 0,
    SMHealthAuthorizationStatusSharingDenied,
    SMHealthAuthorizationStatusSharingAuthorized,
    SMHealthAuthorizationStatusUnsupport,
};

@interface SMHealthManager : NSObject
//@property (nonatomic ,assign)HKAuthorizationStatus stauts;


+ (instancetype)defaultManager;

/**
 请求用户授权
 @param compltion 回调
 */
- (void)requestHealthKitAuthorization:(void(^)(BOOL success, NSError *error))compltion;
 

//获取当天步数
- (void)getStepCount:(void (^)(double stepCount, NSError *error))queryResultBlock;


/**
 获取用户心率
 @param completion 回调   出错时 value = @"--"
 */
- (void)fetchUserHeartRate:(void(^)(NSString *value, NSError *error))completion;
/**
 检查设备是否支持健康数据
 @return yes 支持
 */
- (BOOL)isHealthDataAvailable;
 

//返回当前权限状态
-(SMHealthAuthorizationStatus)appleHealthAuthorizationStatus;
@end

备注：HealthKit授权只是单个项目的，比如步数是步数的授权，心率是心率的授权，因为每次传入的type值是不一样的
tips:
授权页面有 allow 和 notallow的只会弹出一次，如不允许后，下次想打开授权就必须进入到设置页面

//跳转到健康数据设置页面
 [[UIApplication sharedApplication]openURL:[NSURL URLWithString:@"x-apple-health://app/"] options:@{} completionHandler:^(BOOL success) {
                }];

授权页面，写数据关闭时候，读数据打开，其实相当于未授权；
授权页面，写数据打开时候，读数据关闭，其实相当于无数据；
未完待续。。。
