首先要如下图所示 在Xcode中打开HealthKit功能
需要导入头文件
#import
#import
这里我用一个单例类来实验
//HealthKitManage.h
#import
@interface HealthKitManage : NSObject
+(id)shareInstance;

/*

*/
- (NSSet *)dataTypesToWrite;
/*
* @brief 读权限
* @return 集合
*/
- (NSSet *)dataTypesRead;
//获取步数
- (void)getStepCount:(void(^)(double value, NSError *error))completion;
//获取公里数
- (void)getDistance:(void(^)(double value, NSError *error))completion;
/*
* @brief 当天时间段
*
* @return 时间段
*/
+ (NSPredicate *)predicateForSamplesToday;
@end

static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{

});
return manager;
}

@end
使用的时候这样使用就行了
HealthKitManage *manage = [HealthKitManage shareInstance];
[manage authorizeHealthKit:^(BOOL success, NSError *error) {
if (success) {
NSLog(@"success");
[manage getStepCount:^(double value, NSError *error) {
NSLog(@"1count-->%.0f", value);
NSLog(@"1error-->%@", error.localizedDescription);
dispatch_async(dispatch_get_main_queue(), ^{
stepLabel.text = [NSString stringWithFormat:@"步数：%.0f步", value];
distanceLabel.text = [NSString stringWithFormat:@"公里数：%.2f公里", value];
});
}];
}
else {
NSLog(@"fail");
}
这样就获取了走路的数据。
