HealthKit获取健康数据

使用：

#import "HealthKitManage.h"
 
// 获取步数
-(void)getHealthStep
{
 
    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);
                @weakify(self);
                dispatch_async(dispatch_get_main_queue(), ^{
                    NSString *JSSting = [NSString stringWithFormat:@"getHealthStep('%f')",value];
                    //注入js
                    @strongify(self);
                    [self.webView evaluateJavaScript:JSSting completionHandler:^(id _Nullable response, NSError * _Nullable error)
                     {
                         if (error)
                         {
                             NSLog(@"错误：response->%@ error->%@",response,error);
                         }
                     }];
                });
 
            }];
        }
        else {
            NSLog(@"fail");
        }
    }];
}
