SDCAlertView started out as an alert that looked identical to UIAlertView, but had support for a custom content view. With the introduction of UIAlertController in iOS 8, the project was updated to the more modern API that UIAlertController brought.

Note: While UIAlertController supports the action sheet style alert (previously UIActionSheet), SDCAlertView/SDCAlertController do not support this.

• Most UIAlertController functionality
• Custom content views
• Preventing an alert from dismissing when the user taps a button
• Easy presentation/dismissal
• Attributed title label, message label, and buttons
• Alert appearance customization
• Usable from Swift and Objective-C
• Understandable button placement
• UI tests
• Carthage support
• Easy queueing of alerts
• Custom alert behavior

• Xcode 7 or higher
• iOS 8 or higher

If you want to use the library on iOS 7, please use version 2.5.4 (the latest 2.x release). SDCAlertView is not available on iOS 6.1 or below.

To install SDCAlertView using CocoaPods, please integrate it in your existing Podfile, or create a new Podfile:

platform :ios, '8.0'
use_frameworks!

target 'MyApp' do
  pod 'SDCAlertView', '~> 3.0'
end

Then run pod install.

SDCAlertView is written in Swift, but can be used in both Swift and Objective-C.

let alert = AlertController(title: "Title", message: "This is a message")
alert.addAction(AlertAction(title: "Cancel", style: .Default))
alert.addAction(AlertAction(title: "OK", style: .Preferred))
alert.present()

// or use the convenience method:

AlertController.showWithTitle("Title", message: "This is a message", actionTitle: "OK")

let spinner = UIActivityIndicatorView(activityIndicatorStyle: .Gray)
spinner.translatesAutoresizingMaskIntoConstraints = false
spinner.startAnimating()

let alert = AlertController(title: "Title", message: "Please wait...")
alert.contentView.addSubview(spinner)

spinner.centerXAnchor.constraintEqualToAnchor(alert.contentView.centerXAnchor).active = true
spinner.topAnchor.constraintEqualToAnchor(alert.contentView.topAnchor).active = true
spinner.bottomAnchor.constraintEqualToAnchor(alert.contentView.bottomAnchor).active = true

alert.present()

let alert = AlertController(title: "Title", message: "This is a message")
alert.addAction(AlertAction(title: "Dismiss", style: .Preferred))
alert.addAction(AlertAction(title: "Don't dismiss", style: .Default))
alert.setShouldDismissHandler { $0.title == "Dismiss" }
alert.present()

SDCAlertController is a normal view controller, so applying a tintColor to its view will color the buttons and any subviews you add to the contentView.

If you are looking for more customizations, create a type that conforms to VisualStyle and use setVisualStyle() on the AlertController instance. You can also subclass DefaultVisualStyle for a set of default values that you can then override as needed.
