Text Water mark in xcode - ios

Question

hi all i have looked at answers to similar questions and none seem to work for me. I am trying to water mark an image from the camera (image in the below) and add an image and text as a water mark. The below is working perfectly for adding the image but have no idea how to do the text.
WmarkImage = [UIImage imageNamed:#"60.png"];
UIGraphicsBeginImageContext(image.size);
[image drawInRect:CGRectMake(0, 0, image.size.width, image.size.height)];
[WmarkImage drawInRect:CGRectMake(image.size.width - WmarkImage.size.width, image.size.height - WmarkImage.size.height, WmarkImage.size.width, WmarkImage.size.height)];
image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
[imageView setImage:image];

You should convert your text to image then merge them here is an code for this please check this.
NSString* kevin = #"Hello";
UIFont* font = [UIFont systemFontOfSize:12.0f];
CGSize size = [kevin sizeWithFont:font];
// Create a bitmap context into which the text will be rendered.
UIGraphicsBeginImageContext(size);
// Render the text
[kevin drawAtPoint:CGPointMake(0.0, 0.0) withFont:font];
// Retrieve the image
UIImage* image = UIGraphicsGetImageFromCurrentImageContext();
UIImage *MergedImage = [UIImage imageNamed:#"mark.png"];
CGSize newSize = CGSizeMake(200, 400);
UIGraphicsBeginImageContext( newSize );
// Use existing opacity as is
[MergedImage drawInRect:CGRectMake(0,0,newSize.width,newSize.height)];
// Apply supplied opacity if applicable
[image drawInRect:CGRectMake(0,0,newSize.width,newSize.height) blendMode:kCGBlendModeNormal alpha:0.8];
UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
UIImageView *imageView = [[UIImageView alloc]initWithFrame:CGRectMake(20, 20, 300, 400)];
[imageView setImage:newImage];
[self.view addSubview:imageView];

This might help..
CATextLayer *theTextLayer = [CATextLayer layer];
theTextLayer.string = #"Your Text here";
theTextLayer.font = #"Helvetica";
theTextLayer.fontSize = #"12"
theTextLayer.alignmentMode = kCAAlignmentCenter;
theTextLayer.bounds = CGRectMake(0, 0, 40, 40);//give whatever width or height you want
[imageview.layer addSubLayer:theTextLayer];
