You can try with following methods. It will help you to draw text in UIView at the bottom right corner with the help of following attributes.

• NSFontAttributeName - Font name with size
• NSStrokeWidthAttributeName - Stroke Width
• NSStrokeColorAttributeName - Text Color

Objective-C - Draw text in the UIView and return as UIImage.

    -(UIImage *) imageWithView:(UIView *)view text:(NSString *)text {

        UIGraphicsBeginImageContextWithOptions(view.bounds.size, view.opaque, 0.0);

        [view.layer renderInContext:UIGraphicsGetCurrentContext()];

        // Setup the font specific variables
        NSDictionary *attributes = @{
                NSFontAttributeName   : [UIFont fontWithName:@"Helvetica" size:12],
                NSStrokeWidthAttributeName    : @(0), 
                NSStrokeColorAttributeName    : [UIColor blackColor]
        };
        // Draw text with CGPoint and attributes
        [text drawAtPoint:CGPointMake(view.frame.origin.x+10 , view.frame.size.height-25) withAttributes:attributes];

        UIImage * img = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();

        return img;
    }`

Swift - Draw text in the UIView and return as UIImage.

    func imageWithView(view : UIView, text : NSString) -> UIImage {

        UIGraphicsBeginImageContextWithOptions(view.bounds.size, view.opaque, 0.0);
        view.layer.renderInContext(UIGraphicsGetCurrentContext()!);
        // Setup the font specific variables
        let attributes :[String:AnyObject] = [
            NSFontAttributeName : UIFont(name: "Helvetica", size: 12)!,
            NSStrokeWidthAttributeName : 0,
            NSForegroundColorAttributeName : UIColor.blackColor()
        ]
        // Draw text with CGPoint and attributes
        text.drawAtPoint(CGPointMake(view.frame.origin.x+10, view.frame.size.height-25), withAttributes: attributes);
        let img:UIImage = UIGraphicsGetImageFromCurrentImageContext();

        UIGraphicsEndImageContext();
        return img;
    }`
