2 Solutions Collect From Internet About “How can I add a text on an image in iphone?”

I found two ways


    UIImageView *imageView = [[UIImageView alloc] init];
    imageView.frame = CGRectMake(0, 25, 200, 200);
    imageView.image = [UIImage imageNamed:@"Choice set.png"];

    UILabel *myLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 200, 20)];
    myLabel.text = @"Hello There";
    myLabel.textColor = [UIColor whiteColor];
    myLabel.backgroundColor = [UIColor blueColor];
    [imageView addSubview:myLabel];

    [self.view addSubview:imageView];

    [imageView release];
    [myLabel release];


Add text to UIImage

-(UIImage *)addText:(UIImage *)img text:(NSString *)text1{

   int w = img.size.width;
   int h = img.size.height;
   CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();
   CGContextRef context = CGBitmapContextCreate(NULL, w, h, 8, 4 * w, colorSpace, kCGImageAlphaPremultipliedFirst);
   CGContextDrawImage(context, CGRectMake(0, 0, w, h), img.CGImage);

   char* text= (char *)[text1 cStringUsingEncoding:NSASCIIStringEncoding];
   CGContextSelectFont(context, "Arial",20, kCGEncodingMacRoman);
   CGContextSetTextDrawingMode(context, kCGTextFill);
   CGContextSetRGBFillColor(context, 0, 0, 0, 1);
   CGContextShowTextAtPoint(context,10,10,text, strlen(text));
   CGImageRef imgCombined = CGBitmapContextCreateImage(context);


   UIImage *retImage = [UIImage imageWithCGImage:imgCombined];

   return retImage;

then call

UIImage *image = [UIImage imageNamed:@"myimage.png"];

imageView.image = [self addText:image text:@"Hello there"];

Just simple make label with clear background.

yourLabel.backgroundColor = [UIColor clearColor];
