iPhone4(s) - 我对区域监控功能的发现
在我的测试中,我发现我在iPhone4S上的测试区域监控结果有点低于标准。
话虽如此,这就是我的测试中发生的情况:
我尝试通过在开车时为同一位置设置警报来进行测试。有时,警报会立即响起,但大多数情况下不会。我一直想知道这个功能的准确性。该功能可以节省电量,这很好,但如果设备不能及时收到更新,那又有什么用呢。它违背了目的。在这种情况下,用户将对应用程序给予差评 - 因为他们必须切换到耗电的 startUpdatingLocation
因为我开车四处测试,并且由于未及时收到更新,所以我相信,警报不会响起。我的50.0m半径是不是太小了?我可以增加它 - 但用户会很快收到警报!
该功能依赖于用户的设备从一个信号塔传递到下一个信号塔。因此,如果用户碰巧位于没有足够手机信号塔的区域,他/她是否会运气不佳(无法使用此功能)?
想法?建议? 问候....
In my testing, I have found that the results of my tesing regionMonitoring on iPhone4S has been a little under par.
That being said, here's what's happening in my testing:
I try to test by setting an alert for the same location when I drive. Sometimes, the alert goes off right on the dime, but most of the time it does not. I have been wondering about the accuracy of this feature. The feature saves power, which is great, but what good is it if timely updates are not received by the device. It defeats the purpose. In this case the users are going to give bad reviews to the app - because they'll have to switch to startUpdatingLocation which is power hungry
Since I drive around for testing, and because the updates are not received - in time, I believe, the alert does not go off. Is my 50.0m radius too small? I can increase it - but the user will be alerted a little too soon!
The feature relies on user's device being passed by one cell-tower to the next. Therefore, is the user out of luck (for using this feature) if he/she happens to be in area where there are not enough cell towers?
Thoughts? Suggestions?
Regards....

即使对于手持设备上的 GPS 来说,50 米也是相当激进的。尝试先撒一个更广泛的网,然后在目标位置 500-1000m 范围内切换到更积极的位置监控。
50 meters is pretty aggressive even for GPS on a handheld. Try throwing up a wider net first, then switch to more aggressive location monitoring when you were say, within 500-1000m of the target location.
