CocoaPods CocoaPods CocoaPods

Installation

CocoaPods:

pod 'AZDialogView'

Carthage:

github "Minitour/AZDialogViewController"

Manual:

Simply drag and drop the Sources folder to your project.

Usage

Create an instance of AZDialogViewController:

//init with optional parameters let dialog = AZDialogViewController(title: "Antonio Zaitoun", message: "minitour")

Customize:

//set the title color dialog.titleColor = .black //set the message color dialog.messageColor = .black //set the dialog background color dialog.alertBackgroundColor = .white //set the gesture dismiss direction dialog.dismissDirection = .bottom //allow dismiss by touching the background dialog.dismissWithOutsideTouch = true //show seperator under the title dialog.showSeparator = false //set the seperator color dialog.separatorColor = UIColor.blue //enable/disable drag dialog.allowDragGesture = false //enable rubber (bounce) effect dialog.rubberEnabled = true //set dialog image dialog.image = UIImage(named: "icon") //enable/disable backgroud blur dialog.blurBackground = true //set the background blur style dialog.blurEffectStyle = .dark //set the dialog offset (from center) dialog.contentOffset = self.view.frame.height / 2.0 - dialog.estimatedHeight / 2.0 - 16.0

Add Actions:

dialog.addAction(AZDialogAction(title: "Edit Name") { (dialog) -> (Void) in //add your actions here. dialog.dismiss() }) dialog.addAction(AZDialogAction(title: "Remove Friend") { (dialog) -> (Void) in //add your actions here. dialog.dismiss() }) dialog.addAction(AZDialogAction(title: "Block") { (dialog) -> (Void) in //add your actions here. dialog.dismiss() })

Add Image:

dialog.imageHandler = { (imageView) in imageView.image = UIImage(named: "your_image_here") imageView.contentMode = .scaleAspectFill return true //must return true, otherwise image won't show. }

Custom View

/* customViewSizeRatio is the precentage of the height in respect to the width of the view. i.e. if the width is 100 and we set customViewSizeRatio to be 0.2 then the height will be 20. The default value is 0.0. */ dialog.customViewSizeRatio = 0.2 //Add the subviews let container = dialog.container let indicator = UIActivityIndicatorView(activityIndicatorStyle: .gray) dialog.container.addSubview(indicator) //add constraints indicator.translatesAutoresizingMaskIntoConstraints = false indicator.centerXAnchor.constraint(equalTo: container.centerXAnchor).isActive = true indicator.centerYAnchor.constraint(equalTo: container.centerYAnchor).isActive = true indicator.startAnimating()

Present The dialog:

dialog.show(in: self) //or //Make sure to have animated set to false otherwise you'll see a delay. self.present(dialog, animated: false, completion: nil)

Show with completion

dialog.show(in: self) { dialog in // show and then change the offset dialog.contentOffset = self.view.frame.height / 2.0 - dialog.estimatedHeight / 2.0 + 15 }

Design

Change Dialog Width

This has been a requested feature and so I decided to add it. You can change the width of the dialog frame as a ratio in respect to the width of the main view. This can only be doing using the initalizer and the width cannot be modified afterwards.

let dialog = AZDialogViewController(title: "Switch Account", message: "My Message", widthRatio: 1.0)

This will display a dialog which has the same width as the the controller it is presented in.

The default value is 0.75

Customize Action Buttons Style:

dialog.buttonStyle = { (button,height,position) in button.setBackgroundImage(UIImage.imageWithColor(self.primaryColorDark), for: .highlighted) button.setTitleColor(UIColor.white, for: .highlighted) button.setTitleColor(self.primaryColor, for: .normal) button.layer.masksToBounds = true button.layer.borderColor = self.primaryColor.cgColor }

Use custom UIButton sub-class:

dialog.buttonInit = { index in //set a custom button only for the first index return index == 0 ? HighlightableButton() : nil }

Customize Tool Buttons:

dialog.rightToolStyle = { (button) in button.setImage(UIImage(named: "ic_share"), for: []) button.tintColor = .lightGray return true } dialog.rightToolAction = { (button) in print("Share function") } dialog.leftToolStyle = { (button) in button.setImage(UIImage(named: "ic_share"), for: []) button.tintColor = .lightGray return true } dialog.leftToolAction = { (button) in print("Share function") }

Customize Cancel Button Style:

dialog.cancelEnabled = true dialog.cancelButtonStyle = { (button,height) in button.tintColor = self.primaryColor button.setTitle("CANCEL", for: []) return true //must return true, otherwise cancel button won't show. }
