I am using a UISegmentedControl inside a UIToolBar as button. I can\'t use a normal UIButtonBarItem, because I need to set the t
Swift 4
extension UIImage {
class func textEmbededImage(image: UIImage, string: String, color:UIColor, imageAlignment: Int = 0, segFont: UIFont? = nil) -> UIImage {
let font = segFont ?? UIFont.systemFont(ofSize: 16.0)
let expectedTextSize: CGSize = (string as NSString).size(withAttributes: [NSAttributedStringKey.font: font])
let width: CGFloat = expectedTextSize.width + image.size.width + 5.0
let height: CGFloat = max(expectedTextSize.height, image.size.width)
let size: CGSize = CGSize(width: width, height: height)
UIGraphicsBeginImageContextWithOptions(size, false, 0)
let context: CGContext = UIGraphicsGetCurrentContext()!
context.setFillColor(color.cgColor)
let fontTopPosition: CGFloat = (height - expectedTextSize.height) / 2.0
let textOrigin: CGFloat = (imageAlignment == 0) ? image.size.width + 5 : 0
let textPoint: CGPoint = CGPoint.init(x: textOrigin, y: fontTopPosition)
string.draw(at: textPoint, withAttributes: [NSAttributedStringKey.font: font])
let flipVertical: CGAffineTransform = CGAffineTransform(a: 1, b: 0, c: 0, d: -1, tx: 0, ty: size.height)
context.concatenate(flipVertical)
let alignment: CGFloat = (imageAlignment == 0) ? 0.0 : expectedTextSize.width + 5.0
context.draw(image.cgImage!, in: CGRect.init(x: alignment, y: ((height - image.size.height) / 2.0), width: image.size.width, height: image.size.height))
let newImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return newImage!
