Salesforce Mobile iOS SDK | Retrieve the list of objects from salesforce

Salesforce Mobile:

Retrieve the list of objects from salesforce in iOS native mobile app

Description: Using the salesforce mobile iOS-native SDK we can retrieve the list of objects using “requestForDescribeGlobal” SDK method. This method will return the data of all the objects from your salesforce org.

Code:

In your viewDidLoad method make a request to salesforce  
- (void)viewDidLoad
{
    [super viewDidLoad];
    self.title = @"App Title";
    SFRestRequest* request = [[SFRestAPI sharedInstance] requestForDescribeGlobal];
    NSLog(@"request:didLoadResponse: #request: %@", request);
    [[SFRestAPI sharedInstance] send:request delegate:self];
}

To get the result response you can use didLoadResponse Method as:

- (void)request:(SFRestRequest *)request didLoadResponse:(id)jsonResponse {
   NSArray *records = [jsonResponse objectForKey:@"sobjects"];
   NSLog(@"request:didLoadResponse: #records: %lu", (unsigned long)records.count);
   self.dataRows = records;
    dispatch_async(dispatch_get_main_queue(), ^{
        [self.tableView reloadData];
    });
}

Now if you check your console log this will return the no of records found in salesforce i.e number of objects in your salesforce org.

To Populate these records in a list view you can add code as:

- (UITableViewCell *)tableView:(UITableView *)tableView_ cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{
     static NSString *CellIdentifier = @"CellIdentifier";
     UITableViewCell *cell = [tableView_ dequeueReusableCellWithIdentifier:CellIdentifier];
     if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier];
    }
    
    // Configure the cell to show the data.
    NSDictionary *obj = [dataRows objectAtIndex:indexPath.row];
    NSString *fileId = obj[@"id"];
    NSInteger tag = [fileId hash];
    
    cell.textLabel.text =  obj[@"name"];
    cell.detailTextLabel.text = obj[@"label"];    
    }];
    
    return cell;
}

This will populate the list with all the objects of your salesforce org with name and label.
