Swift: Make an image in background of label

I want to put label into an image that is a red rectangle with corner radius (in condition that the image size must to be equal or slightly higher than the label one). For that I found a similar question. I tested this:

theLabel.backgroundColor = UIColor(patternImage: UIImage(named: "blah")!)

But I have problems with the image size. So I tested the second answer:

UILabel *myLabel=[[UILabel alloc] initWithFrame:CGRectMake(0, 0, 320, 20)];

UIImage *img = [UIImage imageNamed:@"a.png"];
CGSize imgSize = myLabel.frame.size;

UIGraphicsBeginImageContext( imgSize );
[img drawInRect:CGRectMake(0,0,imgSize.width,imgSize.height)];
UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

myLabel.backgroundColor = [UIColor colorWithPatternImage:newImage];

Having the last version of Xcode (Xcode 8.0) the CGRectMake is unavailable.

Can anyone help me please?

Try this code: Tested in Swift 3.

Answer 1:

override func viewDidLoad() {
    super.viewDidLoad()

    let label = UILabel()
    label.frame = CGRect(x:0, y:0, width:imageView.frame.width , height:imageView.frame.height)
    label.text = "Some Title"
    label.textAlignment = .center
    label.textColor = .yellow
    label.font = UIFont(name: "HelveticaNeue-medium", size: CGFloat(20))
    imageView.addSubview(label)
}

Output:

enter image description here

Answer 2: Updated

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    imageView.layer.cornerRadius = 10
    imageView.layer.masksToBounds = true

    let label = UILabel()
    label.frame = CGRect(x:0, y:0, width:imageView.frame.width , height:imageView.frame.height)
    label.text = "Some Title"
    label.textAlignment = .center
    label.textColor = .yellow
    label.layer.borderColor  = UIColor.red.cgColor
    label.layer.cornerRadius = 10
    label.layer.masksToBounds = true
    label.layer.borderWidth = 5
    label.font = UIFont(name: "HelveticaNeue-medium", size: CGFloat(26))

    imageView.addSubview(label)
}

Note: You need to workout the image size and label font size.

Output:

Your objective c code in question is changed into swift 3.0 

var myLabel = UILabel(frame: CGRect(x: 0, y: 0, width: 200, height: 21))

var img = UIImage(named:"a")

var imgSize : CGSize =  myLabel.frame.size

UIGraphicsBeginImageContext(CGSize(width: newWidth, height: newHeight))

image.draw(in: CGRect(x: 0, y: 0, width: newWidth, height: newHeight))

let newImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()

myLabel.backgroundColor = UIColor(patternImage: newImage)
