Question

I’ll try and make this quick:

I’ve an external class that parses the JSON from a webservice (the JSON itself is fine, I’ve done it locally now I’m making it web accessible) and then these values will be used for comparisons. However I can’t access the variables in every case. My intent is to parse them once and be able to access them whenever

The parser is being loaded from the the app delegate:

- (void)applicationDidFinishLaunching:(UIApplication *)application{ 
ld =[[ loader alloc] init];
[ld parse];
}

The contents of the connectingDidFinishLoading:

jsonString = [[NSString alloc] initWithData:re encoding:NSUTF8StringEncoding];

//NSLog(@"LOADER %@", jsonString);

SBJsonParser *parser = [SBJsonParser new];

se = (NSMutableDictionary *)[parser objectWithString:jsonString];

searchR = [se objectForKey:@"menu"]; 

s = [[[NSMutableArray alloc] initWithArray:[searchR objectForKey:@"tip1"] ] retain];

NSLog(@"TROLL2 %@", [s objectAtIndex:0  ]);

This comes back correct

However in the first page loaded at the end of the viewDidLoad:

    lt = [[loader alloc] init];
    NSLog(@"CALLED %@", [lt.s objectAtIndex:0] );

This comes back null, and before anyone asks, s is a property of the loader class.
Just wondering if I need a callback to ensure the class is properly loaded or am I just having a stupid day and calling it wrong from the first page

 Here's the `timestaps`:

 2011-07-28 13:59:07.371 [44330:40b] CALLED (null)

Thanks for your time reading this

Wouldn’t you have to access the app delegate rather than initialize a new one?

MyAppDelegate *delegate = (MyAppDelegate *)[[UIApplication sharedApplication] delegate];

NSLog(@"CALLED %@", [delegate.lt.s objectAtIndex:0] );
