Customize the alerts once for everyone

[MattiaConfalonieri]

Hi, There is a away to customize the alerts once for everyone and not in every single call, Title font, color, action color and font ?

Yes sure. You can implement a method in your VC subclass, or create an extension, and add something like that:

func showAlert(_ title: String, message: String, buttonTitle: String, buttonCancel:String, headerImage: UIImage? = nil, completion: @escaping () -> (), cancel: @escaping () -> ()){
        let alertController = PMAlertController(title: title, description: message, image: headerImage, style: .alert)
        alertController.view.layer.cornerRadius = 6
        alertController.alertMaskBackground.backgroundColor = UIColor.black
        alertController.alertMaskBackground.alpha = 0.2
        alertController.alertTitle.textColor = Colors.Gray.darkestGray
        alertController.alertTitle.font = UIFont(name: "HelveticaNeue-Bold", size: 17.0)
        alertController.alertDescription.font = UIFont(name: "HelveticaNeue", size: 15.0)
        alertController.headerViewHeightConstraint.constant = headerImage != nil ? 100.0 : 0.0

        let cancelAction = PMAlertAction(title: buttonCancel, style: .cancel, action: {
            cancel()
        })
        cancelAction.setTitleColor(Colors.Brand.primary, for: .normal)
        cancelAction.titleLabel?.font = UIFont(name: "HelveticaNeue-Medium", size: 17.0)
        alertController.addAction(cancelAction)

        let okAction = PMAlertAction(title: buttonTitle, style: .default, action: {
            completion()
        })
        okAction.setTitleColor(Colors.Brand.primary, for: .normal)
        okAction.titleLabel?.font = UIFont(name: "HelveticaNeue-Medium", size: 17.0)
        alertController.addAction(okAction)

        self.present(alertController, animated: true, completion: nil)
    }

Thanks very much, is perfect.

PS : just a correction for future visitors, in your example

alertController.view.layer.cornerRadius = 6

Should be

alertController.alertView.layer.cornerRadius = 12

When I try to override viewDidLoad in a custom class, I get an error that the nib could not be loaded (using Cocoapods).

Please, open a new issue with your problem and show me your code ;)
