一、访问“健康”正常的步骤：

1、在功能（capabilities）列表中打开HealthKit

capabilities
打开后，会创建一个后缀为entitlements的文件，它是个字典文件：
entitlements

2、在info.plist中添加相关键值：

NSHealthUpdateUsageDescription 请求更新健康数据
NSHealthShareUsageDescription 请求访问健康数据

info.plist

3、直接上代码：

 if ([HKHealthStore isHealthDataAvailable])  {

        // 步数
        HKQuantityType *stepCountType = [HKObjectType quantityTypeForIdentifier:HKQuantityTypeIdentifierStepCount];
        // 步行 + 跑步距离
        HKQuantityType *walkingRunningType = [HKObjectType quantityTypeForIdentifier:HKQuantityTypeIdentifierDistanceWalkingRunning];
        // 活动能量
        HKQuantityType *activeEnergyType = [HKObjectType quantityTypeForIdentifier:HKQuantityTypeIdentifierActiveEnergyBurned];

        // 睡眠分析
        HKCategoryType *sleepType = [HKObjectType categoryTypeForIdentifier:HKCategoryTypeIdentifierSleepAnalysis];

        // 出生日期
        HKCharacteristicType *birthdayType = [HKObjectType characteristicTypeForIdentifier:HKCharacteristicTypeIdentifierDateOfBirth];

        NSMutableSet<HKObjectType *> *readDataTypes = [NSMutableSet setWithObjects:birthdayType, sleepType, stepCountType, walkingRunningType, activeEnergyType, nil];
        NSMutableSet<HKSampleType *> *shareDataTypes = [NSMutableSet setWithObjects:stepCountType, walkingRunningType, activeEnergyType, sleepType, nil];

        if (@available(iOS 9.0, *)) {
            // 月经
            HKCategoryType *menstrualType = [HKObjectType categoryTypeForIdentifier:HKCategoryTypeIdentifierMenstrualFlow];

            [readDataTypes addObject:menstrualType];
            [shareDataTypes addObject:menstrualType];
        }

        HKHealthStore *healthStore = [[HKHealthStore alloc] init];
        [healthStore requestAuthorizationToShareTypes:shareDataTypes readTypes:readDataTypes completion:^(BOOL success, NSError * _Nullable error) {

            if (success) {

                // 操作数据
            } else {

               [self alertWithTitle:@"需要您授权访问健康中心" message:@"设置方法:打开手机设置->隐私->位置信息" okTitle:@"打开设置" cancelTitle:@"取消" okHandler:^(UIAlertAction *action) {
                  NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
                  if (@available(iOS 10.0, *)) {
                    [[UIApplication sharedApplication] openURL:url options:@{} completionHandler:nil];
                  } else {
                    if ([[UIApplication sharedApplication] canOpenURL:url]) {
                      [[UIApplication sharedApplication] openURL:url];
                    }
                  }
                }];
            }
        }];
    } else {

        NSError *error = [NSError errorWithDomain: @"com.project.healthkit" code:2 userInfo: [NSDictionary dictionaryWithObject:@"HealthKit is not available in this Device"                                                                      forKey:NSLocalizedDescriptionKey]];
    }

二、问题：

1、已经按以上步骤操作了，还是会出现崩溃：

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'NSHealthUpdateUsageDescription must be set in the app's Info.plist in order to request write authorization for the following types: HKQuantityTypeIdentifierActiveEnergyBurned, HKCategoryTypeIdentifierMenstrualFlow, HKQuantityTypeIdentifierDistanceWalkingRunning, HKCategoryTypeIdentifierSleepAnalysis, HKQuantityTypeIdentifierStepCount'

之前我也一直运行得没什么问题，忽然有一天就不行了，可能是更新Xcode的什么的吧，这个问题搞得很是头疼，各种尝试后，发现是修改描述的语言就OK了：

描述换成英文

对，就是把中文换成英文，坑爹了吧
