Displaying an array in Xcode and parse.com

Question

Im currently using following code to display an array inside of an UItextView / label / textfield :

  PFQuery *query = [PFQuery queryWithClassName:@"appMsg"];
    [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
        if (!error) {
            // The find succeeded.
            NSLog(@"Successfully retrieved %d scores.", objects.count);
            // Do something with the found objects
            for (PFObject *object in objects) {
                NSString *besked = object[@"besked"];
                msgRecieved0.text = besked;
                NSLog(@"Object values %@",[objects valueForKey:@"besked"]);

            }
        } else {
            // Log details of the failure
            NSLog(@"Error: %@ %@", error, [error userInfo]);
        }
    }];

i have tried to set the NSString to :

NSArray *besked = object[@"besked"];
                msgRecieved0.text = besked[0];
                msgRecieved1.text = besked[1];
                msgRecieved2.text = besked[2];

But again i get an error.

i have tried all i know, and i don't know what i should do to display a "list" of the arrays. I would like to show the first 10 values coming from the array

Have you put breakpoints in? Is besked storing the correct string? — Dehli

There should be n breakpoints. beaked is stored as a string. — Tyler

When just running: NSLog(@"Object values %@",[objects valueForKey:@"besked"]); I'm able to get all the values. — Tyler

PFObject will not respond to Dictionary style element addressing. You must use keyValue coding style code.

Instead of NSString *besked = object[@"besked"];, try this:

NSString *besked = [object objectForKey:@"besked"];

Edit - This might be what you need, if the Parse object is an array.

NSArray* besked = [object objectForKey:@"besked"];
NSString*  str0 = [besked objectAtIndex:0];
NSString*  str1 = [besked objectAtIndex:1];
NSString*  str2 = [besked objectAtIndex:2];

expected method to read array element not found on object op type "NSString *"

What does "besked" store in your Parse database?

random messages like : how are you?, leaving for football, see you later ;), etc.

Then you cannot do: NSArray *besked = object[@"besked"]; it must be what I wrote.
