Getting Started with Entry List Screenlet

Like Guestbook List Screenlet, you’ll create Entry List Screenlet in its own folder inside your app’s project. Create this folder now:

1. In the Finder, create the EntryListScreenlet folder inside your root project folder (on the same level as the GuestbookListScreenlet folder).

2. Drag and drop the EntryListScreenlet folder from the Finder into your Xcode project, under the root project (on the same level as the GuestbookListScreenlet folder). In the dialog that appears, select Copy items if needed, Create groups, and the Liferay Guestbook target. Then click Finish. The EntryListScreenlet folder now appears in your project.

   

   Figure 1: After adding the `EntryListScreenlet` folder, your project should look something like this.

Now you’re ready to begin!

Creating the Model Class

Recall that you need a model class to represent entities retrieved from Liferay DXP. The model class you’ll create for guestbook entries, EntryModel, creates EntryModel objects that represent guestbook entries retrieved from the Guestbook portlet.

Create the following EntryModel class alongside the GuestbookModel class in the model folder:

1. In the Project navigator, right-click the model folder and select New File. In the dialog that appears, fill out each screen as follows:

   • Select iOS → Source → Cocoa Touch Class, and click Next.
   • Name the class EntryModel, set it to extend NSObject, select Swift for the language, and click Next.
   • Make sure the model folder and group is selected, as well as the Liferay Guestbook target (these should be selected by default). Click Create.

   The new class now opens in the editor.

2. Replace the class file’s contents with this code:

   import UIKit
   
   @objc public class EntryModel: NSObject {
   
       public let attributes: [String:AnyObject]
   
       public var entryId: Int64 {
           return attributes["entryId"]?.int64Value ?? 0
       }
   
       public var groupId: Int64 {
           return attributes["groupId"]?.int64Value ?? 0
       }
   
       public var companyId: Int64 {
           return attributes["companyId"]?.int64Value ?? 0
       }
   
       public var userId: Int64 {
           return attributes["userId"]?.int64Value ?? 0
       }
   
       public var userName: String {
           return attributes["userName"] as? String ?? ""
       }
   
       public var createDate: Int64 {
           return attributes["createDate"]?.int64Value ?? 0
       }
   
       public var modifiedDate: Int64 {
           return attributes["modifiedDate"]?.int64Value ?? 0
       }
   
       public var name: String {
           return attributes["name"] as? String ?? ""
       }
   
       public var email: String {
           return attributes["email"] as? String ?? ""
       }
   
       public var message: String {
           return attributes["message"] as? String ?? ""
       }
   
       public var guestbookId: Int64 {
           return attributes["guestbookId"]?.int64Value ?? 0
       }
   
       //MARK: Initializer
   
       public init(attributes: [String:AnyObject]) {
           self.attributes = attributes
       }
   
   }
   

Besides working with entries instead of guestbooks, this class is almost identical to GuestbookModel. For an explanation of the code, see the article on getting started with Guestbook List Screenlet.

Next, you’ll create the Screenlet’s UI.
