If you want the loans in a table, you should read up on UITableView and Cell Styles
you'll add your table, then indicate the number of sections, rows in each section, the content for each cell (row), and what to do if one of the rows is touched:
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
//after turning latestLoans into a property
return self.latestLoans.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
}
cell.textLabel.text=[[self.latestLoans objectAtIndex:indexPath.row] objectForKey:#"name"];
cell.detailTextLabel.text=[[self.latestLoans objectAtIndex:indexPath.row] objectForKey:#"loan_amount"];
}
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
//do something with the row that was selected, like load a table of detailed information
}
