I'm trying to declare a function for showing alerts in my app. To avoid repeating work, i'm trying to use same function for all my app. I tried to do that by creating a class with function showNotification. but when i create an object of that class and call the method, nothing happens. How can i do that? class SharedPropertiesAndMetods : UIViewController { func showNotification(title: String, message: String) { let alertController = UIAlertController(title: title, message: message, preferredStyle: .alert) let defaultAction = UIAlertAction(title: "تائید", style: .default, handler: nil)

⼀、UISegmentedControl的使⽤ 分段控件。每个segment都能被点击，相当于集成了若干个button。 通常我们会点击不同的segment来切换不同的view。 1、常⽤⽅法和属性 initWithItems: //UISegmentedControl独有的初始化⽅法，⽤来创建多个分段 setTitle: forSegmentAtIndex: //为指定下标的分段设置title selectedSegmentAtIndex //（property）被选中的segment tintColor //（property）segmentedControl条的颜⾊（含每个segment的颜⾊） addTarget: action: forControlEvents://给UISegmentedControl添加事件， controlEvent //为UIControlEventValueChanged。 2、使用 RootViewController.m #import "RootViewController.h" #import "MessageViewController.h" #import "PhoneViewController.h" @interface RootViewController () @property ( nonatomic , retain )
