@interface CategoryDetailViewController : UIViewController<UITableViewDataSource,UITableViewDelegate,MKMapViewDelegate>
@property (weak, nonatomic) IBOutlet MKMapView *mapview;

@property (weak, nonatomic) IBOutlet UITableView *tableView;

Answer 1

Make sure that the MapKit.framework is added to your project.

To verify/add the MapKit framework to your project:

• Click on your project file in the left pane, then click on Build Phases.
• Open up the Link Binary with Libraries
• If you do not see the MapKit.framework, you'll want to add it by clicking on the plus sign.

In Swift using a newer version of Xcode, you only need to turn this capability on in the project settings and the error will go away.

Answer 3

It may sound simple but in the project folder of this app the mapkit files were copied,i removed it from this folder through finder and added the mapkit again.now its working.thanks for the comment by @Craig
