Open a view when calloutAccessoryControlTapped triggered - xcode

Question

How can I open a view when I clicked on annotation's button with a navigation button to go back to my mapkit and pass some parameters to the view?
Regards

Answer 1

I have found a solution. Inside:
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation
Add:
UIButton *btn = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[btn addTarget:self action:#selector(pinTouched:) forControlEvents:UIControlEventTouchUpInside];
Then have a function to open the desired view:
-(void)pinTouched:(UIButton *)sender
{
myView.transform = CGAffineTransformMakeScale(.01, .01);
[self.view addSubview:myView];
}

-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id)annotation {
...
...
...
//important
//otherwise calloutAccessoryControlTapped not called
pin.canShowCallout = YES;
pin.calloutOffset = CGPointMake(-10, -10);
UIImageView *leftIconView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"some.png"]];
leftIconView.backgroundColor = [UIColor clearColor];
leftIconView.contentMode = UIViewContentModeScaleAspectFit;
leftIconView.frame = CGRectMake(0, 0, 40, 40);
pin.leftCalloutAccessoryView = leftIconView;
....
....
return pin;
}
-(void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control {
// annotation tapped
float viewWidth = 100;
float viewHeight = 300;
float viewX = 50;
float viewY = 50;
CGRect viewRect = CGRectMake(viewX,viewY, viewWidth, viewHeight);
UIView *viewSub = [[UIView alloc] initWithFrame:viewRect];
viewSub.backgroundColor = [UIColor redColor];
viewSub.tag = 666;
[self.view addSubview:viewSub];
[self.view bringSubviewToFront:viewSub];
}
