iOS 获取健康里的信息(步数和公里数)
//第一步
打开项目--点击capabilities 将HealthKit 打开 如下图
//第二步
1.首先新建一个类 -- 继承NSObject
在.h中
#define HKVersion [[[UIDevice currentDevice] systemVersion] doubleValue]
#define CustomHealthErrorDomain @"com.sdqt.healthError"
@interface HealthKitManage : NSObject
@property (nonatomic, strong) HKHealthStore *healthStore;

- (void)getDistance:(void(^)(double value, NSError *error))completion;
- (void)getStepCount:(void(^)(double value, NSError *error))completion;
+(id)shareInstance
{
static id manager ;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
manager = [[[self class] alloc] init];
});
return manager;
}
- (void)authorizeHealthKit:(void(^)(BOOL success, NSError *error))compltion

}//3.调用单例 -- 在你需要的地方调用两个方法
1.获取每日步数的方法
- (void)onClickBtn1
{
HealthKitManage *manage = [HealthKitManage shareInstance];
[manage authorizeHealthKit:^(BOOL success, NSError *error) {
if (success) {
[manage getStepCount:^(double value, NSError *error) {
dispatch_async(dispatch_get_main_queue(), ^{
//在此处可以获取步数 ---- value
nslog(@"%f",value);
});
}];
}
else {
NSLog(@"fail");
}
}];
}2.获取公里数的方法
- (void)onClickBtn2
{
HealthKitManage *manage = [HealthKitManage shareInstance];
[manage authorizeHealthKit:^(BOOL success, NSError *error) {
if (success) {
[manage getDistance:^(double value, NSError *error) {
dispatch_async(dispatch_get_main_queue(), ^{
获得公里数 : value
});
}];
}
else {
NSLog(@"fail");
}
}];
}
[self onClickBtn1];
[self onClickBtn2];
