IOS 今天学到太多的知识了，赶快记录下来

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 = 78
        UIApplication.sharedApplication().scheduleLocalNotification(localNotification)
        
        UITabBar.appearance().tintColor = UIColor(red: 227.0/255.0, green: 28.0/255.0, blue: 31.0/255.0, alpha: 1)
        UITabBar.appearance().barTintColor = UIColor(red: 0, green: 0, blue: 0, alpha: 1)
        
        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![0].tabBarItem.badgeValue = String(100)
        self.viewControllers![1].tabBarItem.badgeValue = "..."
        self.viewControllers![2].tabBarItem.badgeValue = "s"
        self.viewControllers![3].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 ---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

import UIKit   @UIApplicationMain class 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 ---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

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()     } }
