我如何在iOS的Health Kit中编写Blood Type

Question

I have a HKHealthStore object properly set up, and I am now trying to write user characteristics (ie Date of Birth, Biological Sex, Blood Type and Fitzpatrick Skin Type). I can't find that type in HKQuantityTypeForIdentifier . How do I write blood type to HealthKit in Objective-C ? I am trying the following:

int Dateofbirth=20-10-1995;

NSLog(@“%d”, Dateofbirth);

sex=gender;

BloodType= A+ve;

Fitzpatrick Skin Type= something;

HKQuantityType* bodytemp = [HKQuantityType quantityTypeForIdentifier: HKQuantityTypeIdentifier];

Answer 1

You may have to use characteristicTypeForIdentifier: with HKBloodType .

https://developer.apple.com/library/ios/documentation/HealthKit/Reference/HKObjectType_Class/index.html#//apple_ref/occ/clm/HKObjectType/characteristicTypeForIdentifier :

Constants from Blood type:

typedef enum : NSInteger {
   HKBloodTypeNotSet = 0,
   HKBloodTypeAPositive,
   HKBloodTypeANegative,
   HKBloodTypeBPositive,
   HKBloodTypeBNegative,
   HKBloodTypeABPositive,
   HKBloodTypeABNegative,
   HKBloodTypeOPositive,
   HKBloodTypeONegative,
} HKBloodType;

Answer 2

There is no API to modify user characteristics. The user must update the characteristics themselves in Health.
