???????? notification.alertAction = @"打开";? //提示框按钮

??????? //notification.hasAction = NO; //是否显示额外的按钮，为no时alertAction消失



?????? // NSDictionary *infoDict = [NSDictionary dictionaryWithObject:@"someValue" forKey:@"someKey"];

??????? //notification.userInfo = infoDict; //添加额外的信息

???????

??????? [[UIApplication sharedApplication] scheduleLocalNotification:notification];?????
