Question

I am trying to populate a UITableView with data for a specific user (his projects) from a webservice, after the user as logged into the app.

for example:

tableData = [[NSMutableDictionary alloc] initWithCapacity:DICTIONARY_INITIAL_CAPACITY];
//CURRENT PROJECT
 //get the information from the server
 NSArray *currentProject = [[IHMObjectFinderServices sharedIHMObjectFinderServices]     getCurrentProjectAsArray:connectedUserId];
 if(![currentProject isEqual:[NSNull null]]) {
     //put the info in a dictionnary
     NSMutableDictionary *currentProjectDictionary = [[NSMutableDictionary alloc] initWithCapacity:PROJECT_DICTIONARY_CAPACITY];
     [currentProjectDictionary setObject:[currentProject objectAtIndex:INDEX_PROJECT_NAME] forKey:KEY_PROJECT_NAME];
     [currentProjectDictionary setObject:[currentProject objectAtIndex:INDEX_PROJECT_MANAGER] forKey:KEY_PROJECT_MANAGER];
     [currentProjectDictionary setObject:[currentProject objectAtIndex:INDEX_PROJECT_TAG] forKey:KEY_PROJECT_TAG];
     NSArray *activitiesForProject = [NSArray arrayWithArray:[[IHMObjectFinderServices sharedIHMObjectFinderServices] getAvailableActivities:[currentProjectDictionary valueForKey:KEY_PROJECT_TAG]]];
     [currentProjectDictionary setObject:activitiesForProject forKey:KEY_PROJECT_ACTIVITIES];

     [tableData setObject:currentProjectDictionary forKey:KEY_CURRENT_PROJECT];

At the moment, my table loads in viewDidLoad method, so the problem is that the user is not yet connected when the table is constructed.

I have read about the reloadData method but I am not sure how to proceed to load the table only once, once the user has logged in. Could someone explain to me what is the correct procedure for this ?

Thanks for your help,
Michael

Answer 1

There should be some kind of call back method when the data for the tableView is available. Just put your reloadData in it.

- (void)dataIsAvailable
{
     // ... your code to set the tableData ...

     [self.tableView reloadData];
}
