Question

我正在创建一个UILocalNotification，我需要为此设置多个userInfo，我该怎么做？

    // Create a new notification

    UIApplication* app = [UIApplication sharedApplication];

    UILocalNotification *alarm = [[UILocalNotification alloc] init];

    alarm.fireDate = date;        
    alarm.timeZone = [NSTimeZone localTimeZone];
    alarm.alertBody = msg;        
    alarm.alertAction = @"View";            
    alarm.repeatInterval = NSYearCalendarUnit;
    alarm.soundName=@"happyBirthday.wav";
    alarm.applicationIconBadgeNumber = 1;    

   NSDictionary *userDict = [NSDictionary dictionaryWithObject:detailperson forKey:@"msg"];
   NSDictionary *userDictName = [NSDictionary dictionaryWithObject:detailperson2 forKey:@"name"];

   alarm.userInfo = userDict;
   alarm.userInfo = userDictName;

Answer 1

只要键完全不同，您就可以在字典中拥有多个对象：

NSDictionary *userDict = [NSDictionary dictionaryWithObjectsAndKeys:detailperson, @"msg", detailperson2, @"name", nil];

alarm.userInfo = userDict;

Answer 2

你需要使用combine两个字典与单个Dictionary结合，然后将该字典设置为用户信息。

        NSDictionary *dic=[NSDictionary dictionaryWithObjectsAndKeys:dic1,@"first",dic2,@"second", nil];

       alarm.userInfo=dic

将多个userInfo存储在本地通知中
