有没有什么方法可以获取当前位置，而无需在我的应用程序中使用CLLocationManager委托

Question

I want to provide one method in my library that returns the current location.But I am not able to do that, because location will update and get in CLLocationManager delegate methods.So is there is any way to return back user with location after calling a method in my library.

Thanks in Advance.

Answer 1

You can add a block parameter to your library method that will be called when it receives a location update. That block can then be saved in a property (or into an array if multiple objects could be waiting at the same time).

ps You really should use CLLocationManager . Any other method of determining the location will be less accurate / just as (if not more) time consuming.

You can define a block like (depending on how many locations you want to pass):

typedef void(^LocationUpdateBlock)(CLLocation *location);

Then you add a public interface for the interested classes to register (simple version):

property (copy, nonatomic) LocationUpdateBlock locationUpdateBlock;

Then in your delegate method:

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
    if (self.locationUpdateBlock != nil) {
        self.locationUpdateBlock([locations lastObject]);
    }
}
