Overlays are not captured in MKMapView ScreenShot taken programmatically

I have been trying to take screenshot on MKMapView on which i am drawing user location draw a path using the BreadCrumbs classes CrumbPath and CrumbPathView overlay and overlay view classes.

Here is the code i am using to get the screen Shot:

if ([[UIScreen mainScreen] respondsToSelector:@selector(scale)])
    UIGraphicsBeginImageContextWithOptions(self.view.frame.size, NO, [UIScreen mainScreen].scale);

else
    UIGraphicsBeginImageContext(self.view.frame.size);

[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage * viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIImage * croppedImage = [Utils cropImage:viewImage withFrame:_map.frame];    
UIGraphicsEndImageContext();
UIImageWriteToSavedPhotosAlbum(croppedImage, nil, nil, nil);

ScreenShot i am trying to get Should look like this:

enter image description here

But the ScreenShot i get looks like this:

enter image description here

Use this my custom method it return image of current view..

- (UIImage *)captureView {

   //hide controls if needed
    CGRect rect = [self.view bounds];

    UIGraphicsBeginImageContext(rect.size);
    CGContextRef context = UIGraphicsGetCurrentContext();
    [self.view.layer renderInContext:context];   
    UIImage *img = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return img;

}
