这是我的AppDelegate（由Xcode 8.3，iOS10中的开发人员制作），它完美地发送通知，但我想在我的iPhone仪表板上添加徽章。
我尝试添加application.applicationBadgeNumber = XX，但XX永远不会更新，无论是否有5个新通知或者没有（此时应删除徽章），它都会保留在XX上。
如何正确制作徽章图标流以显示应用中是否有新通知？

适用于iOS 10：
您需要在AppDelegate中实施UserNotifications。
import UserNotifications
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { (granted, error) in
if error != nil {
//
}
}
return true
}
然后你可以这样做：
let content = UNMutableNotificationContent()
content.badge = 10 // your badge count
适用于较旧的iOS：
let badgeCount: Int = 123
let application = UIApplication.sharedApplication()
if #available(iOS 7.0, *) {
application.applicationIconBadgeNumber = badgeCount
}
if #available(iOS 8.0, *) {
application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: [.Badge], categories: nil))
application.applicationIconBadgeNumber = badgeCount
}
if #available(iOS 9.0, *) {
application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: [.Badge], categories: nil))
application.applicationIconBadgeNumber = badgeCount
}
