如何获得iphone中重要位置更新的准确性？

Question

如何知道iPhone中重要位置更新的准确性？作为标准位置，人们可以根据可设置的参数来设置精度等级，但重要的位置精度无法为精度设置，但如何读取接收位置更新的精度？

Answer 1

类CLLocationManager有一个准确性参数，称为desiredAccuracy它是类CLLocationAccuracy。但保持！它不是一类，它是一个typedef double所以这里的常量

extern const CLLocationAccuracy kCLLocationAccuracyBestForNavigation __OSX_AVAILABLE_STARTING(__MAC_10_7,__IPHONE_4_0); 
extern const CLLocationAccuracy kCLLocationAccuracyBest; 
extern const CLLocationAccuracy kCLLocationAccuracyNearestTenMeters; 
extern const CLLocationAccuracy kCLLocationAccuracyHundredMeters; 
extern const CLLocationAccuracy kCLLocationAccuracyKilometer; 
extern const CLLocationAccuracy kCLLocationAccuracyThreeKilometers; 

我建议你做的是你的位置管理的精度分配到一个新的变量它，它像下面的比较：

CLLocationAccuracy locationAccuracy = self.locationManager.desiredAccuracy; 

if (locationAccuracy == kCLLocationAccuracyBest) { 

    NSLog(@"It is the kCLLocationAccuracyBest my life is complete!"); 
} 
else if (/*other comparisons stuff here*/) { 

} 

此外，你必须输入：

#import <CoreLocation/CLLocation.h>
