UIAlertView and UIAlertController IOS 9 - uialertview

Question

I'm editing a project IOS8 to IOS 9, I have difficulty in finding UIAlertView that in IOS 9 tells me he is "DEPRECATED"
I have now replaced UIAlertView with UIAlertController but I find other errors,
can anyone help me solve this problem?
Thank You!
This is my code
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control {
Annotation *myAnnotation = (Annotation *)view.annotation;
CLLocationCoordinate2D currentUserCoords = CLLocationCoordinate2DMake(myMapView.userLocation.coordinate.latitude, myMapView.userLocation.coordinate.longitude);
CLLocationCoordinate2D coord = CLLocationCoordinate2DMake(myAnnotation.coordinate.latitude, myAnnotation.coordinate.longitude);
if ((CLLocationCoordinate2DIsValid(coord))&&(CLLocationCoordinate2DIsValid(currentUserCoords))) {
Annotation *ann = (Annotation *)view.annotation;
selectedCoords = ann.coordinate;
NSString *strTitle = #"GPS";
NSString *strMess = #"Close and open in maps?";
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:strTitle
message:strMess
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"OK", nil];
[alert show];
}
else {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Attention"
message:#"It was not possible to determine the current location.\nPlease check in: /nSettings> Privacy> Location"
delegate:self
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
}
}
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation {
if ([annotation isKindOfClass:[MKUserLocation class]])
return nil;
MKPinAnnotationView *pinView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:#"pinView"];
if (!pinView) {
pinView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:#"pinView"];
pinView.pinColor = MKPinAnnotationColorRed;
pinView.animatesDrop = YES;
pinView.canShowCallout = YES;
pinView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeInfoLight];
if ([UIDevice currentDevice].systemVersion.intValue >= 7)
pinView.tintColor = [UIColor colorWithRed:0.743 green:0.609 blue:0.432 alpha:1.000];
} else {
pinView.annotation = annotation;
}
return pinView;
}
I tried to replace UIAlertView with UIAlertController.

Unlike UIAlertView, UIAlertController declaration is little different and straightforward.
Here is a sample declaration -
UIAlertController *alert = [UIAlertController alertControllerWithTitle:#"Any Title" message:#"Any Message" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *anyAction = [UIAlertAction actionWithTitle:#"ActionName" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
//Any relevant method you want to call
}];
//Adding the alert action
[alert addAction:anyAction];
//Presenting the AlertController
[self presentViewController:alert animated:YES completion:nil];
