IOS8 UILocalNotification 和之前的变化

ios的本地消息需要用户允许后才可以使用

代码如下

UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound categories:nil];

    [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
