use my bellow method...

- (UIImage *)captureView {

     //hide controls if needed
    CGRect rect = [signetureView bounds];//use your signature view's Rect means Frame;

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

}

you can call this above method like bellow...

UIImage *tempImageSave=[self captureView];

Try this hope will help you.

 - (UIImage *) getUIImageWithmyView:(UImyView *)myView
    {
        UIGraphicsBeginImageContextWithOptions(myView.bounds.size, myView.opaque, 0.0);
        [myView.layer renderInContext:UIGraphicsGetCurrentContext()];

        UIImage * myImage = UIGraphicsGetImageFromCurrentImageContext();

        UIGraphicsEndImageContext();

        return myImage;
    }
