iOS8本地通知异常

在iOS8系统开发使用本地通知时，会出现如下的相关提示语：

1 Attempting to schedule a local notification
2 with an alert but haven't received permission from the user to display alerts
3 with a sound but haven't received permission from the user to play sounds

……

原因在于iOS8系统变更了注册方法，需要在ApplicationDelegate里面注册通知才可以,如下代码：

// iOS8注册本地通知

if ([UIApplication instancesRespondToSelector:@selector(registerUserNotificationSettings:)])

{

    [application registerUserNotificationSettings:[UIUserNotificationSettingssettingsForTypes:UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSoundcategories:nil]];

}
