Answer 1

I have been using the following code to add a text to UIImage, hopefully it will help

UIImage *img = [self drawText:@"Your String"
                                inImage:[UIImage imageNamed:@"empty_image.png"]
                                atPoint:CGPointMake(15, 25)];



-(UIImage*) drawText:(NSString*) text
             inImage:(UIImage*)  image
             atPoint:(CGPoint)   point
{

    NSMutableAttributedString *textStyle = [[NSMutableParagraphStyle defaultParagraphStyle] mutableCopy];
    textStyle = [[NSMutableAttributedString alloc] initWithString:[NSString stringWithFormat:@"%@",text]];

    // text color
    [textStyle addAttribute:NSForegroundColorAttributeName value:[UIColor blackColor] range:NSMakeRange(0, textStyle.length)];

    // text font
    [textStyle addAttribute:NSFontAttributeName  value:[UIFont systemFontOfSize:20.0] range:NSMakeRange(0, textStyle.length)];

    UIGraphicsBeginImageContext(image.size);
    [image drawInRect:CGRectMake(0,0,image.size.width,image.size.height)];
    CGRect rect = CGRectMake(point.x, point.y, image.size.width, image.size.height);
    [[UIColor whiteColor] set];

    // add text onto the image
    [textStyle drawInRect:CGRectIntegral(rect)];

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

    return newImage;
}
