查找两点之间距离的新方法
我使用以下代码来查找两点之间的距离：
CLLocation *location1 = [[CLLocation alloc] initWithLatitude:28.3636 longitude:-77.1212];
CLLocation *location2 = [[CLLocation alloc] initWithLatitude:42.353297 longitude:-71.578858];
float target = [location1 getDistanceFrom:location2];
但现在 getDistanceFrom 已被 Apple 弃用。
我应该尝试什么来执行相同的任务？
I was using following code to find distance between 2 points:
CLLocation *location1 = [[CLLocation alloc] initWithLatitude:28.3636 longitude:-77.1212];
CLLocation *location2 = [[CLLocation alloc] initWithLatitude:42.353297 longitude:-71.578858];
float target = [location1 getDistanceFrom:location2];
But now getDistanceFrom is deprecated by Apple.
What should I try to perform same task?

那么
-distanceFromLocation:怎么样？甚至在-getDistanceFrom:的文档中明确提到它是用作替换的方法。How about
-distanceFromLocation:instead? It's even explicitly mentioned in the documentation on-getDistanceFrom:as the method to use as a replacement.您想使用“距离位置：”。有关更多信息，请参阅文档： http://developer .apple.com/library/ios/documentation/CoreLocation/Reference/CLLocation_Class/CLLocation/CLLocation.html
You want to use 'distanceFromLocation:'. See the documentation for more: http://developer.apple.com/library/ios/documentation/CoreLocation/Reference/CLLocation_Class/CLLocation/CLLocation.html
