Manually

Usage

Showing alert

SwiftAlertView.show(title: "Title", message: "Message", buttonTitles: "Cancel", "OK")

Customization

SwiftAlertView.show(title: "Title",
                    message: "Message",
                    buttonTitles: "OK", "Cancel") { alert in
    alert.backgroundColor = .yellow
    alert.cancelButtonIndex = 1
    alert.buttonTitleColor = .blue
}

Handle button clicked events

SwiftAlertView.show(title: "Title",
                    message: "Message",
                    buttonTitles: "Cancel", "OK") {
    $0.style = .dark
}
.onButtonClicked { _, buttonIndex in
    print("Button Clicked At Index \(buttonIndex)")
}

Add text fields

SwiftAlertView.show(title: "Sign in", buttonTitles: "Cancel", "Sign In") { alertView in
    alertView.addTextField { textField in
        textField.placeholder = "Username"
    }
    alertView.addTextField { textField in
        textField.placeholder = "Password"
    }
    alertView.isEnabledValidationLabel = true
    alertView.isDismissOnActionButtonClicked = false
}
.onActionButtonClicked { alertView, buttonIndex in
    let username = alert.textField(at: 0)?.text ?? ""
    if username.isEmpty {
        alertView.validationLabel.text = "Username is incorrect"
    } else {
        alertView.dismiss()
    }
}
.onTextChanged { _, text, textFieldIndex in
    if textFieldIndex == 0 {
        print("Username text changed: ", text ?? "")
    }
}

You can show alert with custom content view

// with xib file
SwiftAlertView.show(nibName: "CustomView", buttonTitles: "OK")

// with custom UIView
SwiftAlertView.show(contentView: customView, buttonTitles: "OK")

Programmatically creating an alert

Initialize an alert

let alertView = SwiftAlertView(title: "Title", message: "Message", buttonTitles: "Cancel", "Button 1", "Button 2", "Button 3")

let alertView = SwiftAlertView(contentView: customView, buttonTitles: "OK")

let alertView = SwiftAlertView(nibName: "CustomView", buttonTitles: "OK")

Show or dismiss

// Show at center of screen
alertView.show()

// Show at center of a view
alertView.show(in: view)

// Programmatically dismiss the alert view
alertView.dismiss()

Handle button clicked event


alertView.onButtonClicked { _, buttonIndex in
    print("Button Clicked At Index \(buttonIndex)")
}
alertView.onActionButtonClicked { _, buttonIndex in
    print("Action Button Clicked At Index \(buttonIndex)")
}

If you don't want to use closures, make your view controller conform SwiftAlertViewDelegate and use delegate methods:

alertView.delegate = self

func alertView(_ alertView: SwiftAlertView, clickedButtonAtIndex buttonIndex: Int) {
    println("Button Clicked At Index \(buttonIndex)")
}

func didPresentAlertView(_ alertView: SwiftAlertView) {
    println("Did Present Alert View")
}

func didDismissAlertView(_ alertView: SwiftAlertView) {
    println("Did Dismiss Alert View")
}

Customization

SwiftAlertView can be customized with the following properties:

public var style: Style = .auto // default is based on system color

public var titleLabel: UILabel! // access titleLabel to customize the title font, color
public var messageLabel: UILabel! // access messageLabel to customize the message font, color

public var dimAlpha: CGFloat = 0.4
