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];
