其中desiredAccuracy属性表示精确度，有5种选择如下:

       desiredAccuracy属性

              描述

kCLLocationAccuracyBest

精确度最佳

kCLLocationAccuracynearestTenMeters

精确度10m以内

kCLLocationAccuracyHundredMeters

精确度100m以内

kCLLocationAccuracyKilometer

精确度1000m以内

kCLLocationAccuracyThreeKilometers

精确度3000m以内

NOTE:精确度越高，用点越多，就要根据实际情况而定。
