AQGridview Not Calling Datasource Methods

Question

I am trying to implement AQGridView based upon the ImageDemo in the /examples folder. I have a view controller with the following declaration:

@interface ImageDemoViewController : UIViewController <AQGridViewDelegate,   AQGridViewDataSource, ImageDemoCellChooserDelegate>
{
...

None of the datasource methods in my view controller such as

- (NSUInteger) numberOfItemsInGridView: (AQGridView *) aGridView
{
return ( [images count] );
}

are being called. Here is where I setup the gridview making my view controller the delegate for the gridview.

- (void)viewDidLoad
{
[super viewDidLoad];   
self.gridView.autoresizingMask = UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight;
self.gridView.autoresizesSubviews = YES;
self.gridView.delegate = self;
self.gridView.dataSource = self;

images=[[NSMutableArray alloc]init];
[images addObject:@"http://t3.gstatic.com/images?q=tbn:ANd9GcTOXAzFMoK441mcn9V0OemVe_dtAuCpGjBkLrv4rffyOjYIo45BEw"];
[self.gridView reloadData];
}

If I set a breakpoint on

[self.gridView reloadData];

the line is executed but reloadData method in AQGridView is not called. The only difference from the ImageDemo is I do not have a .xib file for the view controller. Have I forgotten to hook up something, resulting in the datasource methods not being called?

If there's no XIB, then who's creating the gridView? If it's never created, then it would be NIL, and you'd have the behavior you describe. (If that's it, then just adding: self.gridview = [AQGridView alloc] initWithFrame: ...]; should suffice.

The gridview is created programmatically in the view controller. – ChrisP Jun 24 '11 at 00:41
Sorry to be picky, but have you checked with the debugger or NSLog that self.gridView is a valid AQGridView at the point you're calling reloadData? There's no delegate concept at that point, just a straight method call. If it's valid, then there's no way that [x y] doesn't call the method y of object x. – mackworth Jun 24 '11 at 15:54

Maybe you could try implementing this:

- (void)LoadSearch
{
    NSURL *test1 = [NSURL URLWithString:@"http://www.4ddraws.com/search_iphone.asp"];
    NSURLRequest *test = [NSURLRequest requestWithURL:test1];
    [web4D setScalesPageToFit:(YES)];
    [web4D loadRequest:test];

}

Had the same problem. Solved by replacing the view with the AQGridView.
~~[self.view addSubview:self.gridView]~~

 self.view = self.gridView;

Full method:

- (void) viewDidLoad
{
    [super viewDidLoad];

    self.gridView = [[AQGridView alloc] init];
    self.gridView.autoresizingMask = UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight;
    self.gridView.autoresizesSubviews = YES;
    self.gridView.delegate = self;
    self.gridView.dataSource = self;

    self.view = self.gridView;

    [self.gridView reloadData];
}

I found the reload data part was the critical piece here. – Jason C. Howlin May 05 '13 at 20:30 — Jason C. Howlin, May 05 '13 at 20:30
