UPDATE 2:
Here is the existing code within maps, but it is like the annotations get all out of order with the pins. One time a pin will be green, the next time I run it, the same pin is red. Where is the disconnect coming from?
-(void) viewWillAppear:(BOOL)animated {
self.annotationArray = [[NSMutableArray alloc] init];
CLLocationCoordinate2D coord = {.latitude = 15.8700320, .longitude = 100.9925410};
MKCoordinateSpan span = {.latitudeDelta = 3, .longitudeDelta = 3};
MKCoordinateRegion region = {coord, span};
[mapViewUI setRegion:region];
PFQuery *query = [PFQuery queryWithClassName:@"Share"];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (!error) {
self.mapViewData = objects;
for (int i=0;i<[objects count];i++)
{
// Question * q = [[Question alloc]init];
PFObject * obj = [self.mapViewData objectAtIndex:i];
NSLog(@"%@", obj);
self.theObject = obj;
NSString *string = obj[@"WhereAt"];
NSArray *stringArray = [string componentsSeparatedByString: @","];
CLLocationDegrees myLatitude = [[stringArray objectAtIndex:0] doubleValue];
CLLocationDegrees myLongitude = [[stringArray objectAtIndex:1] doubleValue];
CLLocationCoordinate2D coord2 = {.latitude = myLatitude, .longitude = myLongitude};
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
dateFormatter.dateFormat = @"MMM dd, yyyy";
MKPointAnnotation *annotation2 = [[MKPointAnnotation alloc] init];
[annotation2 setCoordinate:coord2];
[annotation2 setTitle:obj[@"FamilyName"]];
[annotation2 setSubtitle:obj[@"Result"]];
[mapViewUI addAnnotation:annotation2];
}
} else {
// Log details of the failure
NSLog(@"Error: %@ %@", error, [error userInfo]);
}
}];
}
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation {
if (annotation == mapViewUI.userLocation)
{
return nil;
}
else
{
NSUInteger index = [[mapView annotations] indexOfObject:annotation];
PFObject *objectForCurrentAnnotation = [self.mapViewData objectAtIndex:index];
MKPinAnnotationView *annotationView = [[MKPinAnnotationView alloc] init];
annotationView.enabled = YES;
annotationView.canShowCallout = YES;
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
dateFormatter.dateFormat = @"MMM dd, yyyy";
NSString *theResult = objectForCurrentAnnotation[@"Result"];
NSLog(@"Result is %@", theResult);
if ([theResult isEqualToString:@"Accepted Bible"]) {
NSLog(@"Accepted");
annotationView.pinTintColor = [UIColor greenColor];
}
else if ([theResult isEqualToString:@"Requested Different Material"]) {
NSLog(@"Different");
annotationView.pinTintColor = [UIColor blackColor];
}
else if ([theResult isEqualToString:@"Not Home"]) {
NSLog(@"Not Home");
annotationView.pinTintColor = [UIColor yellowColor];
}
else if ([theResult isEqualToString:@"Rejected Bible"]) {
NSLog(@"Rejected");
annotationView.pinTintColor = [UIColor redColor];
}
return annotationView;
}
return nil;
}
UPDATE:
I see now that the issue is that self.theObject is set one time, so it just pulls data from that for everything not handled by Annotations. I guess the issue now is, how can I get it to show for each object instead of whatever the last one set was?
My app uses Parse.com and PFObjects. The app queries the PFObject to get all the data for each entry in the row, pulls out the coordinates for a given location for that entry, along with various bits of data, and adds an annotation for each of those. When I set the MKAnnotationView for this so that I can have multiple colored pins outside of what Apple generally lets you easily do, I run into issues. The image and some of the data for the annotation sets each pin to whatever the last one called was. The title and subtitle are fine, but not the color or callout image. Here is my code, what is going on wrong here?
