JSONModel：MKAnnotation和CLLocationCoordinate2D

Question

I am using JSONModel ( https://github.com/icanzilb/JSONModel ) inorder to handle my JSON data. I just have problem related to adding a CLLocationCoordinate2D property in my JSONModel Subclass, in order to respond to the MKAnnotation protocol. Since the incoming JSON dosen't contain a coordinate field, but seperated fields with Lat & Lon, and since CLLocationCoordinate2D isn't an object, JSONModel want let me ignore protocol.

This is my code:

@protocol Store @end
@interface Store : JSONModel <MKAnnotation>

@property (nonatomic, copy, readonly) NSString *Name;
@property (nonatomic, copy, readonly) NSNumber *Longitude;
@property (nonatomic, copy, readonly) NSNumber *Latitude;

//Can be ignored since it is not an object type. 
@property (nonatomic, assign) CLLocationCoordinate2D <Ignore> coordinate;
@end

How can I ignore the coordinate property?

Just check the documentation

http://cocoadocs.org/docsets/JSONModel/0.11.0/Classes/JSONModel.html#//api/name/propertyIsIgnored:

Here's the code for your model:

+ (BOOL)propertyIsIgnored:(NSString *)propertyName
{
  if ([propertyName isEqualToString:@"coordinate"]) {
    return YES;
  }
  return NO;
}

Edit: Although what I would do if I were you is to have a custom transformer for the coordinate property that would read the 2 incoming json keys and produce a location struct for you automatically. Just an idea...
