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
