Apple Mach-O Linker error (APActivityIcon)

Question

I've a problem! Sorry I'm new to programming and I dont know what to do. I implemented some code, to customize my ActivitiViewController. I created a new class, which I linked to my code:

  - (IBAction)share:(id)sender
 {
     Class avcClass = NSClassFromString(@"UIActivityViewController");
     if (avcClass) {

         APActivityProvider *ActivityProvider = [[APActivityProvider alloc] init];
         UIImage *ImageAtt = [UIImage imageNamed:@"MyApp Icon 512x512.png"];
         NSArray *Items = @[ActivityProvider, ImageAtt];


         APActivityIcon *ca = [[APActivityIcon alloc] init];
         NSArray *Acts = @[ca];

         UIActivityViewController *ActivityView = [[UIActivityViewController alloc]
                                                    initWithActivityItems:Items
                                                    applicationActivities:Acts];
         [ActivityView setExcludedActivityTypes:
          @[UIActivityTypeAssignToContact,
          UIActivityTypeCopyToPasteboard,
          UIActivityTypePrint,
          UIActivityTypeSaveToCameraRoll,
          UIActivityTypePostToWeibo]];

         [self presentViewController:ActivityView animated:YES completion:nil];
         [ActivityView setCompletionHandler:^(NSString *act, BOOL done)
          {
              NSString *ServiceMsg = nil;
              if ( [act isEqualToString:UIActivityTypeMail] )           ServiceMsg = @"Mail sended!";
              if ( [act isEqualToString:UIActivityTypePostToTwitter] )  ServiceMsg = @"Post on twitter, ok!";
              if ( [act isEqualToString:UIActivityTypePostToFacebook] ) ServiceMsg = @"Post on facebook, ok!";
              if ( [act isEqualToString:UIActivityTypeMessage] )        ServiceMsg = @"SMS sended!";
              if ( done )
              {
                  UIAlertView *Alert = [[UIAlertView alloc] initWithTitle:ServiceMsg message:@"" delegate:nil cancelButtonTitle:@"ok" otherButtonTitles:nil];
                  [Alert show];


          }}];

.........However, I run the code, but I still get an error! My two files I created are named APActivityProvider. So now I get that error and dont know how to treat this. Whats the error of my architecture?

Any tipps, suggestions or solutions?

Thanks

Have you imported APActivityIcon.h? Is activity icon part of the correct target? (Check the file inspector on the left hand side, there should be checkboxes for your targets. Select your APActivityIcon.m, and check in the file inspector its targets). The error seems to suggest it cannot find it. — WDUK
