ios - 位置经理提供什么作为其最近的值(value)

Question

我问了一个关于如何从这里获取旧位置的问题:

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations 

我得到了回复

You should create and use a mutable array of previous locations that were updated from previous calls to "locationManager: didUpdateLocations:". Link

现在我对 Location Awareness guide 中的那个感到困惑Apple 是这样说的:

If a location update has already been delivered, you can also get the most recent location data directly from the CLLocationManager object without waiting for a new event to be delivered.

我不明白这一点。请帮帮我。

Answer 1

如果你看Apple's documentation for CLLocationManager, you'll see it has a property you can access that's named "location" .

此属性包含最后报告的位置数据。

每当新位置得到解决和报告时，该属性大概应该更新。

不过，一般来说，您会希望通过委托(delegate)方法传递的更新让您的用户了解当前位置的最新信息。
