Examples

Setup a camera in a few lines.

 let camera = Camera()

 override func viewDidLoad() {
     super.viewDidLoad()
     
     camera.previewLayer?.frame = view.bounds
     view.layer.addSublayer(camera.previewLayer!)
     
 }
 
 func buttonTapped() {
     camera.captureImage()
 }

Easily crop, mask, or resize an image

 let image = UIImage(named: "myImage")
 
 let croppedImage = image.cropToBounds(CGRect(x: 10, y: 10, width: 10, height: 10))
 let maskedImage = image.maskWithImage(anotherImage)
 let resizedImage = image.resizeImage(CGSize(width: 10, height: 10))

Find all faces in an image

 let image = UIImage(named: "myImage")!
 let ci = CIImage(CGImage: image.CGImage!)

 let faces = ci.faceRects()

Quickly setup a view with a nib.

 class View: NibView {
 
   @IBOutlet weak var button: UIButton!
 
   override var nibName: String {
       return "ViewNibName"
   }
 
   override func configure() {
       super.configure()
       button.backgroundColor = UIColor.blueColor()
   }

 }

Add a label with a top, middle, or bottom vertical alignment.

  var label = VerticallyAlignedLabel()
  label.verticalAlignment = .Top

You can check for valid input in a text field. Below the field checks for any input at all (length > 0). The label's border is set to green once it is considered valid.

  class ViewController: UIViewController, InputTextFieldValidityDelegate {

   var field = InputTextField()
  
   override func viewDidLoad() {
       super.viewDidLoad()
      
       field.setValidChecker { (input) -> Bool in
           return input.length > 0
       }
    }

   func inputDidBecomeValid(field: InputTextField) {
         print("valid")
         field.layer.borderColor = UIColor.greenColor().CGColor
         field.layer.borderWidth = 1
    }
  
    func inputDidBecomeInvalid(field: InputTextField) {
        print("invalid")
        field.layer.borderWidth = 0
    }

  }
