This framework allows you to display a grid of views.

Its API is very similar to the API of UITableView : it can reuses/recycle cells to avoid too much allocations and it uses tiling to avoid having a too big memory footprint.

You can configure its properties like rowHeight, columnCount, ...

• Add the OHGridView project to your Xcode4 workspace
• Go to your application project's Build Phases (select your application project in the Project Navigator, then select the "Build Phases" tab), expand the "Link binariy with libraries" section and click on the "+" button to add libOHGridView that should be proposed in the list now
• In your application project's Build Settings (select your application project in the Project Navigator, then select the "Build Settings" tab), add ${SRCROOT}/../OHGridView — or whatever the path to the OHGridView folder is, relative to your project root ${SRCROOT} — to the "User Header Search Path" setting so you can #import "OHGridView.h".

Once you have added added the OHGridView.xcodeproj to your workspace and configured your application project like described above, you can simply #import "OHGridView.h" in your source and then implement the methods of the OHGridViewDataSource protocol, like you would do for a UITableView:

-(NSUInteger)numberOfItemsInGridView:(OHGridView *)aGridView;
-(OHGridViewCell*)gridView:(OHGridView *)aGridView cellAtIndexPath:(NSIndexPath *)indexPath;

You can also implement the GridViewDelegate protocol especially to handle when a cell is tapped:

-(void)gridView:(OHGridView *)aGridView didSelectCellAtIndexPath:(NSIndexPath *)indexPath;

See the "GridViewExample" project for a basic usage example (including changing the number of columns used when the iPhone orientation changes)

OHGridView is compatible with both ARC and non-ARC projects.

In fact, as OHGridView is provided as a separated project, it has its own build settings (that's the advantage of integrating it as a separate project in your workspace, compared to directly add the OHGridView.h/OHGridView.m files to your application project). As a consequence, the build settings of your own application, including the activation of ARC or not, won't affect OHGridView project's build settings and the OHGridView building operation.

Moreover, as a matter of fact, the OHGridView project itself can be both compiled with ARC turned on or off, thanks to #if precompiler directives.

• This means that even if it is not the recommanded way to include OHGridViewin your application, including the files directly in your own xcodeproj will still work, whatever the ARC setting is for your project.
• This also means that even if the OHGridView project is currently configured to be compiled with ARC turned on, you may turn this setting off if you prefer (for whatever reason) have the OHGridView.m file being compiled without ARC.

In short, whether your project uses ARC or not won't matter, you can use OHGridView in any case.
