EasyAlertControllers
感谢DOAlertController的作者，因为这个库已经很长时间没有更新，不能用于swift 4.0或更高版本，也没有适应iPhoneX系列设备。在这里，我更新了一个新的版本来解决上述问题。
特性
- 自定义Alert/Action Sheet样式
- 适配最新Swift版本
- 适配所有设备类型（包括iPhoneX系列设备）。
安装
CocoaPods
使用CocoaPods安装EasySegmentedControl是最简单的方法。
pod 'EasyAlertControllers'
旧式方法
- 将
EasyAlertControllers.swift添加到您的项目中。
使用
所有样式
- 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)
present(alertCotroller, animated: true, completion: nil)
}
- 其他Alert（显示带两个自定义按钮的警报）
func showOtherAlert(_: IndexPath) {
let title = "Other Alert"
let message = "A message should be a short, complete sentence."
let cancelButtonTitle = "Cancel"
let otherButtonTitleOne = "Choice One"
let otherButtonTitleTwo = "Choice Two"
let destructiveButtonTitle = "Destructive"
let alertController = EasyAlertControllers(title: title, message: message, preferredStyle: .alert)
// Create the actions.
let cancelAction = EasyAlertAction(title: cancelButtonTitle, style: .cancel) { action in
NSLog("The \"Other\" alert's cancel action occured.")
}
let otherButtonOneAction = EasyAlertAction(title: otherButtonTitleOne, style: .default) { action in
NSLog("The \"Other\" alert's other button one action occured.")
}
let otherButtonTwoAction = EasyAlertAction(title: otherButtonTitleTwo, style: .default) { action in
NSLog("The \"Other\" alert's other button two action occured.")
}
let destructiveButtonAction = EasyAlertAction(title: destructiveButtonTitle, style: .destructive) { action in
NSLog("The \"Other\" alert's destructive button action occured.")
}
// Add the actions.
alertController.addAction(cancelAction)
alertController.addAction(otherButtonOneAction)
alertController.addAction(otherButtonTwoAction)
alertController.addAction(destructiveButtonAction)
present(alertController, animated: true, completion: nil)
}
- TextEntryAlert
func showTextEntryAlert(_: IndexPath) {
let title = "Text Entry Alert"
let message = "A message should be a short, complete sentence."
let cancelButtonTitle = "Cancel"
let otherButtonTitle = "OK"
let alertController = EasyAlertControllers(title: title, message: message, preferredStyle: .alert)
// Add the text field for text entry.
alertController.addTextFieldWithConfigurationHandler { textField in
// If you need to customize the text field, you can do so here.
}
// Create the actions.
let cancelAction = EasyAlertAction(title: cancelButtonTitle, style: .cancel) { action in
NSLog("The \"Text Entry\" alert's cancel action occured.")
}
let otherAction = EasyAlertAction(title: otherButtonTitle, style: .default) { action in
NSLog("The \"Text Entry\" alert's other action occured.")
}
// Add the actions.
alertController.addAction(cancelAction)
alertController.addAction(otherAction)
present(alertController, animated: true, completion: nil)
}
- SecureTextEntryAlert
func showSecureTextEntryAlert(_: IndexPath) {
let title = "Secure Text Entry Alert"
let message = "A message should be a short, complete sentence."
let cancelButtonTitle = "Cancel"
let otherButtonTitle = "OK"
let alertController = EasyAlertControllers(title: title, message: message, preferredStyle: .alert)
// Add the text field for the secure text entry.
alertController.addTextFieldWithConfigurationHandler { textField in
// Listen for changes to the text field's text so that we can toggle the current
// action's enabled property based on whether the user has entered a sufficiently
// secure entry.
NotificationCenter.default.addObserver(self, selector: #selector(self.handleTextFieldTextDidChangeNotification(_:)), name:UITextField.textDidChangeNotification, object: textField)
textField?.isSecureTextEntry = true
}
// Stop listening for text change notifications on the text field. This closure will be called in the two action handlers.
let removeTextFieldObserver: () -> Void = {
NotificationCenter.default.removeObserver(self, name: UITextField.textDidChangeNotification, object: alertController.textFields!.first)
}
// Create the actions.
let cancelAction = EasyAlertAction(title: cancelButtonTitle, style: .cancel) { action in
NSLog("The \"Secure Text Entry\" alert's cancel action occured.")
removeTextFieldObserver()
}
let otherAction = EasyAlertAction(title: otherButtonTitle, style: .default) { action in
NSLog("The \"Secure Text Entry\" alert's other action occured.")
removeTextFieldObserver()
}
// The text field initially has no text in the text field, so we'll disable it.
otherAction.enabled = false
// Hold onto the secure text alert action to toggle the enabled/disabled state when the text changed.
secureTextAlertAction = otherAction
// Add the actions.
alertController.addAction(cancelAction)
alertController.addAction(otherAction)
present(alertController, animated: true, completion: nil)
