swift 的 UIAlertController使用
1.弹出带有取消和确定以及标题的alertController,并且附带UITextField @IBAction func testAlert(sender: AnyObject) {
let alertController = UIAlertController(title: "提示",message: "哈哈哈,你懂的",preferredStyle:UIAlertControllerStyle.Alert);
let cancelAction = UIAlertAction(title: "取消",style: UIAlertActionStyle.Cancel) { (action : UIAlertAction) -> Void in
print("点击了取消按钮");
}
let confirmAction = UIAlertAction(title: "确定",style: UIAlertActionStyle.Default) { (action :UIAlertAction) -> Void in
print("点击了确定按钮");
}
alertController.addAction(cancelAction); alertController.addAction(confirmAction);
alertController.addTextFieldWithConfigurationHandler { (textField : UITextField) -> Void in
//配合textField的代理方法使用 textField.placeholder = "请输入密码"; textField.secureTextEntry = true; textField.tag = 111; textField.delegate = self;
}
self.presentViewController(alertController,animated: true) { () -> Void in
print("已经弹出");
};
