iOS 怎么在程序关闭的时候移除所有本地通知

除了其他人的答案：

- (void)applicationWillTerminate:(UIApplication *)application {
   // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}

还可以监听通知：

       [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(willTerminate:) name:UIApplicationWillTerminateNotification object:nil];

APPdelegate 中有代理方法，applicationWillTerminate:
这里面去移除监听

- (void)applicationWillTerminate:(UIApplication *)application {
    // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}

在appdelegate的析构中移除
