Usage

Basic usage without any buttons:

CDAlertView(title: "Awesome Title", message: "Well explained message!", type: .notification).show()

NOTE: You can use it without buttons. Touch outside of the popup or move it will disappear it if there is no action button. If there is an action button, only pressing button will disappear it.

To add new buttons:

let alert = CDAlertView(title: "Awesome Title", message: "Are you in?!", type: .notification)
let doneAction = CDAlertViewAction(title: "Sure! 💪")
alert.add(action: doneAction)
let nevermindAction = CDAlertViewAction(title: "Nevermind 😑")
alert.add(action: nevermindAction)
alert.show()

To enable text field in popup:

alert.isTextFieldHidden = false

Custom view is also supported. If you want to use custom view, you are responsible for the height of custom view. Custom view is used in UIStackView.

let myCustomView = UIVIew(frame: myFrame)
// Don't forget to handle height of `myCustomView`
alert.customView = myCustomView

CDAlertView types:

public enum CDAlertViewType {
    case error, warning, success, notification, alarm, noImage, custom(image:UIImage)
}

Initialization

Advanced Alert Initialization

To use it with your custom icon, initialize without type (or with .empty) and set your icon and background color:

let alert = CDAlertView(title: "Awesome Title", message: "Well explained message!", type: .custom(image: UIImage(named:"YourAwesomeImage")))
alert.circleFillColor = UIColor.yourAmazingColor

Hide Alert with your animation

let alert = CDAlertView(title: "Awesome Title", message: "Well explained message!", type: .success)
alert.hideAnimations = { (center, transform, alpha) in
    transform = CGAffineTransform(scaleX: 3, y: 3)
    alpha = 0
}
alert.hideAnimationDuration = 0.88
alert.show()

Hide Alert with timer

let alert = CDAlertView(title: "Awesome Title", message: "Well explained message!", type: .success)
alert.autoHideTime = 4.5 // This will hide alert box after 4.5 seconds
