Pass object with NSNotificationCenter to other view

Question

I want to pass an object named country, that loads all the cit

Answer 1

For Swift You can pass dictionary with using the below code

NSNotificationCenter.defaultCenter().postNotificationName(aName: String, object anObject: AnyObject?, userInfo aUserInfo: [NSObject : AnyObject]?)

for example

NSNotificationCenter.defaultCenter().postNotificationName("OrderCancelled", object: nil, userInfo: ["success":true])

And read this dictionary from

 func updated(notification: NSNotification){

         notification.userInfo?["success"] as! Bool 
    }

Answer 2

Oooooo, so close. I have a feeling you do not understand what an NSDictionary is though.

Post your notification with this:

Country *country = [[[Country alloc] init] autorelease];
//Populate the country object however you want

NSDictionary *dictionary = [NSDictionary dictionaryWithObject:country forKey:@"Country"];

[[NSNotificationCenter defaultCenter] postNotificationName:@"citiesListComplete" object:nil userInfo:dictionary];

then get the country object like this:

- (void)checkMSG:(NSNotification *)note {

    Country *country = [[note userInfo] valueForKey:@"Country"];

    NSLog(@"Received Notification - Country = %@", country);
}

You don't need to convert your object into a NSDictionary. Instead, you need to send a NSDictionary with your object. This allows you to send lots of information, all based on keys in the NSDictionary, with your NSNotification.
