MKAnnotation random order in MKMapView - iphone

Question

I have a table view with an ordered list of objects, ordered by distance between me and the object. I need to show annotations in a map to show to the user the position of the objects but i need to show in the same order than table´s order because then i need to get with one has been pressed to show info of each object.
The problem is that when I put the annotations in the map each time I put them the tag number of the annotation is different. Is like the map added the annotations in a random order.
I have an annotations array and then I add that array to the map:
MKPointAnnotation* tallerAnnotation = [[MKPointAnnotation alloc] init];
[tallerAnnotation setCoordinate:CLLocationCoordinate2DMake([taller getLatitudTaller], [taller getLongitudTaller])];
[tallerAnnotation setTitle:[taller getNombre]];
[tallerAnnotation setSubtitle:[taller getDomicilio]];
[annotations addObject:tallerAnnotation];
And then add the array to the map:
[mapa addAnnotations:annotations];
Here is the code where I custom the annotation:
- (MKAnnotationView *) mapView: (MKMapView *) mapa viewForAnnotation: (id <MKAnnotation>) annotation_ {
MKPinAnnotationView *pin = (MKPinAnnotationView *) [self.mapa dequeueReusableAnnotationViewWithIdentifier: #"YourPinId"];
if (pin == nil) {
pin = [[MKPinAnnotationView alloc] initWithAnnotation:annotation_ reuseIdentifier: #"YourPinId"];
}
else {
pin.annotation = annotation_;
}
if ([[annotation_ title]isEqualToString:#"Tu posición"])
pin.pinColor = MKPinAnnotationColorRed;
else
{
[pin setCanShowCallout:YES];
pin.pinColor = MKPinAnnotationColorGreen;
UIButton *rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[rightButton addTarget:self action:#selector(getInfoTalleres:) forControlEvents:UIControlEventTouchUpInside];
[rightButton setTag:posicionActualTaller];
pin.rightCalloutAccessoryView = rightButton;
UILabel *l1=[[UILabel alloc] init];
l1.frame=CGRectMake(0, 5, 50, 15);
l1.backgroundColor = [UIColor clearColor];
l1.textColor = [UIColor whiteColor];
l1.font=[UIFont fontWithName:#"Arial Rounded MT Bold" size:(10.0)];
l1.text=[[[mainDelegate getTalleres]objectAtIndex: posicionActualTaller]getDistancia];
posicionActualTaller +=1;
UIView *leftCAV = [[UIView alloc] initWithFrame:CGRectMake(0,0,50,15)];
[leftCAV addSubview : l1];
pin.leftCalloutAccessoryView = leftCAV;
}
pin.animatesDrop = YES;
return pin;
}
I would like to do something like this:
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
NSLog(#"Tag del taller = %i",[control tag]);
[mainDelegate setTallerActual:[[mainDelegate getTalleres]objectAtIndex:[control tag]]];
[self detalleTaller];
}
[control tag] has differents values each time I enter into map view so that way it´s impossible do something like [objects objectAtIndex:[control tag]];
Please I need help.
Thanks in advance.
Ok finally I have found a solution.
When I create the
UIButton *rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[rightButton addTarget:self action:#selector(getInfoTalleres:) forControlEvents:UIControlEventTouchUpInside];
for the annotation I assign the annotation title to the button this way:
[rightButton setTitle:[annotation_ subtitle] forState:UIControlStateNormal];
Then:
-(void)getInfoTalleres:(UIButton* )sender
{
for (int i = 0; i < [[mainDelegate getTalleres]count]; i++)
{
if ([[sender currentTitle] isEqualToString:[[[mainDelegate getTalleres]objectAtIndex:i]getDomicilio]])
{
[mainDelegate setTallerActual:[[mainDelegate getTalleres]objectAtIndex:i]];
[self detalleTaller];
break;
}
}
}
Hope somebody can use this solution.
Thanks a lot Cocoa.
Regards.
