User are allowed to select multiple recipes and share them on Facebook in the following ways: To give you a better idea of how multiple selection works, we’ll continue to tweak the Recipe app. To enable multiple selection, the trick is to set the property to YES. The allowsMultipleSelection property of UICollectionView class controls whether multiple items can be selected simultaneously. However, user is allowed to select single item by default. UICollectionView supports both single and multiple selection. This dismissViewControllerAnimated method tells the view controller to dismiss.

Therefore, we add a line of code to deselect the selected item once the image is displayed in the modal view controller.ĭon’t forget to add the import statement at the very beginning of RecipeCollectionViewController.m, otherwise, your code won’t compile properly: In collection view, when user taps on a collection cell, the cell changes to the highlighted state and then to the selected state. Therefore, we’ll pick the first index path and retrieve the selected image (Line 5-6). As for this example, we only have single item selection. Each of the index path corresponds to a particular selected item.

The reason is that UICollectionView supports multiple selection that we’ll cover in the next section.

You may wonder why there are multiple index paths returned. The UICollectionView class provides the indexPathsForSelectedItems method that returns the index paths for the selected items. Note: If you forget how segue works, it is highly recommended to check out our segue tutorial before proceeding. Your View Controller should look similar to the below one: Set the name of the button item as “Close”. Lastly, add a navigation bar to the top of view and assign it with a Bar Button Item. Then add an Image View to it and set the width and height to 320 and 200 respectively. Go to Storyboard, drag a View Controller from Object library. To begin, let’s design the view controller for displaying the recipe photo. When user taps any of the recipe photo, the app will bring up a modal view to display the photo in higher resolution.

If you find any problem opening/compiling the project, please upgrade your Xcode to the latest version.įirst, we’ll improve the Recipe app to handle single selection. Please note that the Xcode project is created using Xcode 4.6 and tested on iOS 6.

To spare you from setting up the Xcode project, you can download this Xcode template.

However, it’ll give you an idea of how to interact with collection view. The interface of the app is very simple and will not win any design award. Users are allowed to select multiple photos and share them on Facebook.

We’ll also implement Facebook sharing in the app in order to show you multiple item selection.When user taps a recipe photo, the app will bring up a modal view and display the photo in larger size. To demonstrate how you can handle single selection, we’ll improve the Recipe app.To provide you with a working example of how the item selection works, we’ll continue to improve the Recipe app. But to give you a better idea, we’ll show how to interact with the collection items such as the ways to handle single and multiple item selection. However, we haven’t covered how to interact with the collection view cell.Īs mentioned before, the Collection View works in a way pretty much like Table View. You should already know how to display items using UICollectionView. In the past two tutorials, we covered the basics of UICollectionView and header/footer customization.
