*注意：需要iOS8以上，调用前判断一下； 另外证书需要打开获取健康数据功能，自己百度。
获取健康数据，每天运动步数，实时获取。*

这是哥哥我研究了几天英文文档才弄出来的（英文不好，痛苦死了），第一次写博客，就贡献了。
补充使用方法：
//倒入头文件 #import "HealthManager.h"
[[HealthManager shareInstance] getKilocalorieUnit:[HealthManager predicateForSamplesToday] quantityType:[HKQuantityType quantityTypeForIdentifier:HKQuantityTypeIdentifierActiveEnergyBurned] completionHandler:^(double value, NSError *error) {
if(error)
{
DebugLog(@"error = %@",[error.userInfo objectForKey:NSLocalizedDescriptionKey]);
}
else
{
DebugLog(@"获取到的卡路里 ＝ %.2lf",value);
}
}];
[[HealthManager shareInstance] getRealTimeStepCountCompletionHandler:^(double value, NSError *error) {
NSLog(@"当天行走步数 = %.2lf",value);
}];
其中对错误处理不够完善，项目刚开始，没多少时间去看，自己解决哈。
