TabBarController 修改tabbar的背景颜色和选中时候的颜色：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Override point for customization after application launch.        application.registerUserNotificationSettings(UIUserNotificationSettings(
            forTypes:UIUserNotificationType.Badge, categories: nil))        UIApplication.sharedApplication().cancelAllLocalNotifications()        let localNotification = UILocalNotification()
        localNotification.applicationIconBadgeNumber =
        UIApplication.sharedApplication().scheduleLocalNotification(localNotification)        UITabBar.appearance().tintColor = UIColor(red: 227.0/255.0, green: 28.0/255.0, blue: 31.0/255.0, alpha: )
        UITabBar.appearance().barTintColor = UIColor(red: , green: , blue: , alpha: )        return true
    }

设置 Tabbaritem 上的图章

class myTabBarController: UITabBarController, UITabBarControllerDelegate {    override func viewDidLoad() {
        super.viewDidLoad()        self.delegate = self        NSLog("Number of view controllers: \(self.viewControllers?.count)")        self.viewControllers![].tabBarItem.badgeValue = String()
        self.viewControllers![].tabBarItem.badgeValue = "..."
        self.viewControllers![].tabBarItem.badgeValue = "s"
        self.viewControllers![].tabBarItem.badgeValue = "-"        //self.viewControllers![0].tabBarItem.        // Do any additional setup after loading the view.
    }    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }    /*
    // MARK: - Navigation    // In a storyboard-based application, you will often want to do a little preparation before navigation
    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        // Get the new view controller using segue.destinationViewController.
        // Pass the selected object to the new view controller.
    }
    */}

Swift – 设置应用程序图标的提醒个数（右上角小红圈）

2015-07-22 10:20发布：hangge浏览：433

使用UILocalNotification除了可以实现本地消息的推送功能（可以设置推送内容，推送时间，提示音），还可以设置应用程序右上角的提醒个数。

下面演示如何设置，效果图如下： — AppDelegate.swift —

123456789101112131415161718192021222324252627282930 import UIKit @UIApplicationMainclass AppDelegate: UIResponder, UIApplicationDelegate { var window: UIWindow? func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { application.registerUserNotificationSettings(UIUserNotificationSettings( forTypes: UIUserNotificationType.Sound | UIUserNotificationType.Alert | UIUserNotificationType.Badge, categories: nil)) return true } func applicationWillResignActive(application: UIApplication) { } func applicationDidEnterBackground(application: UIApplication) { } func applicationWillEnterForeground(application: UIApplication) { } func applicationDidBecomeActive(application: UIApplication) { } func applicationWillTerminate(application: UIApplication) { }}

— ViewController.swift —

123456789101112131415161718192021222324252627 import UIKit class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() //发送通知消息 scheduleNotification(); } //发送通知消息 func scheduleNotification(){ //清除所有本地推送 UIApplication.sharedApplication().cancelAllLocalNotifications() //创建UILocalNotification来进行本地消息通知 var localNotification = UILocalNotification() //设置应用程序右上角的提醒个数 localNotification.applicationIconBadgeNumber = 78; UIApplication.sharedApplication().scheduleLocalNotification(localNotification) } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() }}
