iOS 6 CLLocationManager最后位置

Question

So, as of iOS 6, -locationManager:didUpdateToLocation:fromLocation: is deprecated.

Apple suggests, instead, using -locationManager:didUpdateLocations: , which provides anywhere from one to a series of recent location changes. However, in the incredibly likely chance it provides a locations array of length 1, there appears to be no way to access the fromLocation:(CLLocation *)oldLocation parameter of old.

Is there a way to get at this information without using deprecated methods?

Answer 1

您只需要将一个属性设置为locationManager：didUpdateLocations：返回的值，就可以将其用作fromLocation，然后再次调用该方法，并将其返回的值用作toLocation。

Answer 2

正如rdelmar所说，如果您需要先前的位置，则只需将从locationManager:didUpdateLocations:收到的最后一个位置存储在一个ivar或属性中，如果locationManager:didUpdateLocations:返回一个只有一个值的数组，请获取先前保存的值在您的ivar /属性中，并将其用于您的“旧”位置。
