EasyAlertControllers

Thanks for the author of DOAlertController, Because this library has not been updated for a long time, it can not be used in the latest version of swift 4.0 or above, and it has not adapted to the iPhoneX series devices. Here I update a new version to solve the above problems.

Features

• Customized Alert/Action Sheet style
• Adapted to the latest swift version
• Adapted to all device types(includes iPhoneX series devices).

Installation

CocoaPods

The easiest way of installing EasySegmentedControl is via CocoaPods.

pod 'EasyAlertControllers'

Old-fashioned way

• Add EasyAlertControllers.swift to your project.

Usage

All styles

• SimpleAlert

func showSimpleAlert(_: IndexPath) {
        let title = "Simple Alert"
        let message = "A message should be a short, complete sentence."
        let cancelButtonTitle = "OK"
        let alertController = EasyAlertControllers(title: title, message: message, preferredStyle: .alert)
        // Create the action.
        let cancelAction = EasyAlertAction(title: cancelButtonTitle, style: .cancel) { action in
            NSLog("The simple alert's cancel action occured.")
        }
        // Add the action.
        alertController.addAction(cancelAction)
        present(alertController, animated: true, completion: nil)
    }

• OkayCancelAlert

func showOkayCancelAlert(_: IndexPath) {
        let title = "Okay/Cancel Alert"
        let message = "A message should be a short, complete sentence."
        let cancelButtonTitle = "Cancel"
        let otherButtonTitle = "OK"
        let alertCotroller = EasyAlertControllers(title: title, message: message, preferredStyle: .alert)
        // Create the actions.
        let cancelAction = EasyAlertAction(title: cancelButtonTitle, style: .cancel) { action in
            NSLog("The \"Okay/Cancel\" alert's cancel action occured.")
        }
        let otherAction = EasyAlertAction(title: otherButtonTitle, style: .default) { action in
            NSLog("The \"Okay/Cancel\" alert's other action occured.")
        }
        // Add the actions.
        alertCotroller.addAction(cancelAction)
        alertCotroller.addAction(otherAction)

    }

        }
        // Stop listening for text change notifications on the text field. This closure will be called in the two action handlers.
