Property title Copy attribute does not match property inherited from MKAnnotation

copy, properties, title

Solution

Change:

@property (nonatomic, retain) NSString *Title;

into:

@property (nonatomic, copy) NSString *title;

Problem

These are the lines that are invoking a warning: @property (nonatomic, retain) NSString *Title; @property (nonatomic, retain) NSString *Subtitle; My Warning is:property 'title' 'copy' attribute does not match the property inherited from 'MKAnnotation' Any ideas? Thanks in advance! ``` #import <Foundation/Foundation.h> #import <MapKit/MapKit.h> @interface MapAnnotation : NSObject <MKAnnotation> { CLLocationCoordinate2D coordinate; NSString *title; NSString *subtitle; int listIndex; } @property (nonatomic) CLLocationCoordinate2D coordinate; @property (nonatomic, retain) NSString *Title; @property (nonatomic, retain) NSString *Subtitle; @property (nonatomic) int listIndex; @end ```
