It may be easier to use a UIImageView and a separate `UILabel1 to display the text. I think you would have more control over the positioning.

- (UIImage *)burnTextIntoImage:(NSString *)text :(UIImage *)myImage {
UIImage *myImage = [UIImage imageNamed:@"promoicon.png"];
UIGraphicsBeginImageContext(myImage.size);
[myImage drawInRect:CGRectMake(0,0,myImage.size.width,myImage.size.height)];
UITextView *myText = [[UITextView alloc] init];
myText.font = [UIFont fontWithName:@"TrebuchetMS-Bold" size:15.0f];
myText.textColor = [UIColor whiteColor];
myText.text = NSLocalizedString(@"My Text", @"");
myText.backgroundColor = [UIColor clearColor];
CGSize maximumLabelSize = CGSizeMake(myImage.size.width,myImage.size.height);
CGSize expectedLabelSize = [myText.text sizeWithFont:myText.font constrainedToSize:maximumLabelSize lineBreakMode:NSLineBreakByWordWrapping];
myText.frame = CGRectMake((myImage.size.width / 2) - (expectedLabelSize.width / 2),(myImage.size.height / 2) - (expectedLabelSize.height / 2),myImage.size.width,myImage.size.height);
[[UIColor whiteColor] set];
[myText.text drawInRect:myText.frame withFont:myText.font];
UIImage *myNewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return myNewImage; }
