I'm using JSON-Framework in my project successfully to decode JSON send from a server.
Now I need to do it the other way around and I'm facing problems as the data to be sent is a NSMutableArray fetched from CoreData.
When using
NSString* jsonString = [menuItems JSONRepresentation]
I get the message "JSON serialisation not supported for MenuItems".
Do I need to convert the NSMutableArray to some other format so the JSON-Framework can serialize it?
Thanks for any help,
Miguel
I finally solved it, but I'm not sure if it's the best/most elegant way to do it.
NSMutableArray* items = [[NSMutableArray alloc] init];
for (MenuItems* item in menuItems) {
[items addObject:[NSArray arrayWithObjects:item.id,[item.modified description],nil]];
}
NSString *post = [NSString stringWithFormat:@"currentData=%@",
[items JSONRepresentation]];
Explanation:
I first thought that the problem was the NSMutableArray, but then realized that it was the contents of it. So I just get the information I need out of it and saved it as NSArray which JSON-Framework does accept :-)
