I really need some more help! I am trying to pass an array from one view controller to another. I think the latter being a 'child' view controller? My code is as follows: MainViewController.h: <pre><code>#import <UIKit/UIKit.h> #import <AudioToolbox/AudioToolbox.h> #import <AVFoundation/AVFoundation.h> @interface HelloWorldIOS4ViewController : UIViewController <UITableViewDelegate, UITableViewDataSource, UITextFieldDelegate, AVAudioPlayerDelegate> { NSMutableArray *countProductCode; UIPopoverController *detailViewPopover; } @property (nonatomic, retain) NSMutableArray *countProductCode; @property (nonatomic, retain) UIPopoverController *detailViewPopover; - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data; ... @end </code></pre> MainViewController.m <pre><code>#import "HelloWorldIOS4ViewController.h" #import "JSON.h" #import "PopoverContentViewController.h" @implementation HelloWorldIOS4ViewController @synthesize detailViewPopover; @synthesize countProductCode; - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { NSString *jsonString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; NSDictionary *results = [jsonString JSONValue]; NSLog(@"RETURN: %@", results); [countProductCode removeAllObjects]; NSArray *products = [results objectForKey:@"items"]; for (NSDictionary *row in products) { NSString *code = [row objectForKey:@"ic"]; [countProductCode addObject:code]; } PopoverContentViewController.countProductCodes = countProductCode; } </code></pre> PopoverViewController.h: <pre><code>@interface PopoverContentViewController : UITableViewController { NSMutableArray *countProductCodes; } @property (nonatomic, retain) NSMutableArray *countProductCodes; @end </code></pre> PopoverViewController.m: <pre><code>#import "PopoverContentViewController.h" #import "HelloWorldIOS4ViewController.h" @implementation PopoverContentViewController @synthesize countProductCodes; ... </code></pre> I have cut a lot out, but I know from a load of NSLog's dotted around that I get the data back etc, but I cannot pass the array <code>countProductCode</code> to the <code>PopoverViewController's</code> <code>countProductCodes</code> array. I keep getting <blockquote> "Accessing unknown 'setCountProductCodes:' class method" </blockquote> errors. This may be something really silly that I'm doing but it's driving me crazy! Can anyone help please? Thanks James

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
