微信,QQ中都有运动数据展示,在好友中的排名等,这里所提供的是通过修改健康中心的数据来达到刷数据的效果,让你成为数据中的运动达人,不过只是娱乐而已,而且微信只有第一次运行才会成功,其他时候都是读取手机本身的数据,而不对第三方修改的数据进行统计,QQ就没这个问题啦,当然数据修改不要超过100000步,太多了QQ也不认识了
获取健康中心的读写权限
// 设置请求的权限,这里我们只获取读取和写入步数
let stepType: HKQuantityType? = HKObjectType.quantityType(forIdentifier: .stepCount)
let dataTypesToRead = NSSet(objects: stepType as Any)
// 权限请求
self.healthStore?.requestAuthorization(toShare: dataTypesToRead as? Set<HKSampleType>, read: dataTypesToRead as? Set<HKObjectType>, completion: { [unowned self] (success, error) in
// 得到权限后就可以获取步数和写入了
if success {
self.fetchSumOfSamplesToday(for: stepType!, unit: HKUnit.count()) { (stepCount, error) in
// 获取到步数后,在主线程中更新数字
DispatchQueue.main.async {
self.stepsNumberLabel.text = "\(stepCount!)"
}
}
} else {
let alert = UIAlertController(title: "提示", message: "不给权限我还怎么给你瞎写步数呢,可以去设置界面打开权限", defaultActionButtonTitle: "确定", tintColor: UIColor.red)
alert.show()
}
})读取步数
