adding UIlabel to camera overlay view uiimagepickercontroller Xcode objc

I want to add some UILabels on top of my UIImagePickerController's custom OverlayView but can't seem to get it working.

Here is my code.

-(IBAction)getPhoto:(id)sender{
picker = [[UIImagePickerController alloc] init];

picker.allowsEditing = NO;

picker.sourceType =  UIImagePickerControllerSourceTypeCamera ;
picker.showsCameraControls = NO;
self.picker.navigationBarHidden = YES;
self.picker.toolbarHidden = YES;

OverlayView = [[OverlayView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width,1024)];
UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(OverlayView.frame.size.height/2, OverlayView.frame.size.width/2, 30, 100)];
label.textColor = [UIColor whiteColor];
label.text = @"find Me";
[self.OverlayView addSubview:label];
[self.OverlayView bringSubviewToFront:label];
picker.cameraOverlayView = OverlayView;
CGSize screenSize = [[UIScreen mainScreen] bounds].size;   // 320 x 568

float scale = screenSize.height / screenSize.width*3/4;  // screen height divided by the pickerController height ... or:  568 / ( 320*4/3 )

CGAffineTransform translate=CGAffineTransformMakeTranslation(0,(screenSize.height - screenSize.width*4/3)*0.5);
CGAffineTransform fullScreen=CGAffineTransformMakeScale(scale, scale);
picker.cameraViewTransform =CGAffineTransformConcat(fullScreen, translate);
[self presentViewController: picker animated:YES completion:NULL];

}

the overview shows up and it is full screen but no label any ideas

Your label is just offscreen, check its frame

You can place it for instance like that, at least it will be visible

self.overlayView = [[OverlayView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(self.overlayView.frame.size.width/2, self.overlayView.frame.size.height/2, 30, 100)];
