ios - 仅在 iOS 9 上崩溃 : [MKPlacemark initWithCoordinate:]: unrecognized selector

Question

代码:

-(void)getRouteDirections{
    MKDirectionsRequest *request = [[MKDirectionsRequest alloc] init];
    [request setSource:[MKMapItem mapItemForCurrentLocation]];

    // It crashes on this line:      
    MKPlacemark * placemark = [[MKPlacemark alloc]initWithCoordinate:_location.coordinate];
}

异常(exception):

-[MKPlacemark initWithCoordinate:]: unrecognized selector sent to instance

仅在 iOS 9 上崩溃。我该如何解决这个问题？

来自Larme的回答评论:

- (instancetype)initWithCoordinate:(CLLocationCoordinate2D)coordinate;自 iOS10 起可用。

对于 iOS 9 或更早版本，initWithCoordinate:addressDictionary:自 iOS 3 起可用。
