Modifying HelloRepo to display node information

#import "AlfrescoDocumentFolderService.h"

            

So your #imports look like the following:

#import <UIKit/UIKit.h>

#import "AlfrescoSession.h"
#import "AlfrescoNode.h"
#import "AlfrescoDocumentFolderService.h"

            

The SkyVaultDocumentFolderService class needs to be included as this service will be used to retrieve information about the selected node.

              
@property (strong, nonatomic) SkyVaultDocumentFolderService *documentFolderService;              
              
            

The DocumentTableViewController.h code should now be as follows:

              
#import <UIKit/UIKit.h>

#import "AlfrescoSession.h"
#import "AlfrescoNode.h"
#import "AlfrescoDocumentFolderService.h"

@interface DocumentTableViewController : UITableViewController

@property (strong, nonatomic) SkyVaultNode *node;
@property (strong, nonatomic) id<AlfrescoSession> session;
@property (strong, nonatomic) SkyVaultDocumentFolderService *documentFolderService;

- (id)initWithSession:(id<AlfrescoSession>)createdSession andNode:(AlfrescoNode *)nodeToBeDisplayed;

@end              
              
            

You are not going to need this method as it is a callback used when a row is selected. In this view you don't need to carry out any specific actions if a row is selected, you are just going to view information about the node selected in the previous view.

              
#pragma mark - Table view delegate

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    // Navigation logic may go here. Create and push another view controller.
    /*
     <#DetailViewController#> *detailViewController = [[<#DetailViewController#> alloc] initWithNibName:@"<#Nib name#>" bundle:nil];
     // ...
     // Pass the selected object to the new view controller.
     [self.navigationController pushViewController:detailViewController animated:YES];
     */
}
              
              
            

              
    // Uncomment the following line to preserve selection between presentations.
    // self.clearsSelectionOnViewWillAppear = NO;
 
    // Uncomment the following line to display an Edit button in the navigation bar for this view controller.
    // self.navigationItem.rightBarButtonItem = self.editButtonItem;              
              
            

This code will not be required for the purposes of this tutorial. The application does not need to deal with row selections in this particular view, and no table items will be edited.

The - (void)viewDidLoad method should now match the following code:

              
 - (void)viewDidLoad
{
    [super viewDidLoad];

}             
              
            

              
- (void)viewDidLoad
{
    [super viewDidLoad];
    self.title = @"Node Details";

}              
            

This will change the text in the navigation controller to indicate the nature of the current view.

              
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    
    // Configure the cell...
    if (cell == nil)
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
        
        // SECTION 0 - Summary
        
        if (indexPath.section == 0) {
            
            switch (indexPath.row) {
                case 0:
                    cell.textLabel.text = self.node.name;
                    break;
                    
                case 1:
                    if (self.node.isDocument == TRUE)
                    {
                        cell.textLabel.text = @"isDocument == TRUE";
                    }
                    else if (self.node.isFolder == TRUE)
                    {
                        cell.textLabel.text = @"isFolder == TRUE";
                    }
                    else
                    {
                        cell.textLabel.text = @"Not document or folder.";
                    }
                    break;
                    
                case 2:
                    cell.textLabel.text = @"Latest version label will go here";
                    break;
                    
                default:
                    break;
            }
            
        }
        
        
        // SECTION 1 - General
        
        if (indexPath.section == 1)
        {
            cell.textLabel.text = @"General info will go here.";
        }
        
        // SECTION 2 - Comments
        
        
        if (indexPath.section == 2)
        {
            cell.textLabel.text = @"Comments will go here.";
        }
        
        
        // SECTION 3 - Tags
        
        if (indexPath.section == 3)
        {
            cell.textLabel.text = @"Tags will go here.";
        }
        
        // SECTION 4 - Versions
        
        if (indexPath.section == 4)
        {
            cell.textLabel.text = @"Versions will go here.";
        }
        
    }
    
    return cell;
}


            

This code sets the cell text depending on which row is being drawn. Note that for the general, comments, tags, and versions sections you just set placeholder text. More useful code will be added for these sections in later tutorials.

For now, focus on the following snippet for the summary section:

              
        if (indexPath.section == 0) {
            
            switch (indexPath.row) {
                case 0:
                    cell.textLabel.text = self.node.name;
                    break;
                    
                case 1:
                    if (self.node.isDocument == TRUE)
                    {
                        cell.textLabel.text = @"isDocument == TRUE";
                    }
                    else if (self.node.isFolder == TRUE)
                    {
                        cell.textLabel.text = @"isFolder == TRUE";
                    }
                    else
                    {
                        cell.textLabel.text = @"Not document or folder.";
                    }
                    break;
                    
                case 2:
                    cell.textLabel.text = @"Latest version label will go here";
                    break;
                    
                default:
                    break;
            }
            
        }              
              
            

There are three rows in this section. The first row (case 0) will display the node name. The second row (case 1) will display whether the node is a document, a folder, or something else. The third row (case 2) will be used to display the version label for the latest version of the document, but currently is a placeholder - this feature will be added in a later tutorial.
