Add Textfield MDCAlertController IOS

Question

There is no method similar to the addtextfield method in Uialertcontroller. I haven't found any examples of how I can customize MDCAlertControllers. Anybody have an idea?

Answer 1

I think this is not possible. The docs say:

MDCAlertController class is intended to be used as-is and does not support subclassing. The view hierarchy for this class is private and must not be modified.

Answer 2

This is now possible by using accessoryView.
Simply set it to be your custom view and set the alert message to be blank.

alertController.accessoryView = myCustomView

Code example (using SnapKit for layout)

let title = "My title"        
let alertController = MDCAlertController(title: title, message: "")
let confirmAction = MDCAlertAction(title:"Confirm") { [weak self] _ in
    //your action here
}
let cancelAction = MDCAlertAction(title:"Cancel")

let width = UIScreen.main.bounds.width * 0.91
let testView = UIView()
let button = UIButton()
button.setTitle("Test", for: .normal)
testView.addSubview(button)
button.snp.makeConstraints { (make) in
    make.center.equalToSuperview()
}
testView.backgroundColor = .blue //just to show where the view is
testView.snp.makeConstraints { (make) in
    make.width.equalTo(width)
    make.height.equalTo(100)
}

alertController.accessoryView = testView
alertController.addAction(confirmAction)
alertController.addAction(cancelAction)
alertController.defaultTheming()

present(alertController, animated:true)

Result from above code
