A custom "modal" alert view for iOS 7 and 8 written in Swift, with a couple basic themes and support for custom icons and fonts. Inspired by and modeled after vikmeup's SCLAlertView.
The most minimal alert just has a title.
JSSAlertView().show(
self, // the parent view controller of the alert
title: "I'm an alert" // the alert's title
)You'll always want to first pass a reference to the view controller that you wish to add the overlay and alert subviews to.
Besides the default show() method you can call any of four alert themes: info(), success(), warning(), and danger().
JSSAlertView().success(
self,
title: "Great success",
text: "This is the built-in .success style"
)You can customize button text, add a custom icon and customize the alert color.
var customIcon:UIImage! // your custom icon UIImage
var customColor:UIColor! // base color for the alert
JSSAlertView().show(
self,
title: "Another alert",
text: "An alert with more customizations.",
buttonText: "Right on",
color: customColor,
iconImage: customIcon)You can also provide a callback function to run after the alert is dismissed, specify custom fonts and change the alert's text color from dark to light.
func myCallback() {
// this'll run after the alert is dismissed
}
var alertview = JSSAlertView().show(self,
title: "Yet another alert",
text: "Callbacks, fonts and text colors"
)
alertview.addAction(myCallback) // Method to run after dismissal
alertview.setTitleFont("ClearSans-Bold") // Title font
alertview.setTextFont("ClearSans") // Alert body text font
alertview.setButtonFont("ClearSans-Light") // Button text font
alertview.setTextTheme(.Light) // can be .Light or .DarkFinally, two-button alerts with a cancel button on the left are possible by passing in some cancelButtonText. The button on the left side of the alert will reflect that text and simply dismiss the alert when tapped, with an optional cancel callback. The right-hand button will also dismiss the alert as usual, with the appropriate close callback if present.
func myCancelCallback() {
// this'll run if cancel is pressed after the alert is dismissed
}
var alertview = JSSAlertView().show(
self,
title: "I'm an alert",
text: "An alert with two buttons. Dismiss by tapping the left, and do something else by tapping the right.",
buttonText: "OK",
cancelButtonText: "Cancel" // This tells JSSAlertView to create a two-button alert
)
alertview.addCancelAction(myCancelCallback)See the included example project for more!
Just add the JSSAlertView.swift file to your Xcode project. Maybe one day I'll make it available through CocoaPods.
