我正在开发一个带推送通知的应用，我希望延迟推送通知权限的出现，直到用户第三次进入我的应用程序。所以他应该对我的应用感兴趣，然后我想问他的许可。 我有办法做到这一点吗？ 我搜索了很多方法，比如这里： 重置推送应用的通知设置 但我没有得到任何有用的答案。 请帮助。 谢谢

推荐答案

维护一个在中递增的userDefault - （BOOL）应用程序：（UIApplication * ）application didFinishLaunchingWithOptions：（NSDictionary *）launchOptions {}method

Maintain one userDefault which increments in "- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {}" method

如果userDefault大于3，则寻求Notification的许可

if the userDefault is greater than 3,then seek for permission of Notification

if NSUserDefaults.standardUserDefaults().objectForKey("launchCount")?.integerValue >= 3{ if UIApplication.sharedApplication().respondsToSelector("isRegisteredForRemoteNotifications") { UIApplication.sharedApplication().registerUserNotificationSettings( UIUserNotificationSettings( forTypes: [.Alert, .Badge, .Sound], categories: nil)) UIApplication.sharedApplication().registerForRemoteNotifications() } }
