Multiple UITableView on a single UIView

I'm trying to put 2 TableViews on a single UIView. I've implemented the methods needed. I've tested the apps with breakpoints and the project fails at this method.

I have 2 tableviews : radios_tv and presets_tv Two arrays from the delegate from which count is obtained: array_radios and array_presets array_radios contains 10 elements. array_presets contains 30 elements.

I've tested for the part:

if (tableView == self.presets_tv) {
    return appDelegate.array_presets.count; //Contains 30 elements in the array_radios
}

Everything is ok if I put return anything below 10. But the project fails with a SIGABRT error if the return is greater than 10 and in my case, as the array_presets contains 30 elements, 开发者_开发知识库it fails.

Below is my code:

    - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
MyApplicationAppDelegate *appDelegate = (MyApplicationAppDelegate *)[[UIApplication sharedApplication] delegate];

if (tableView == self.radios_tv){
    return appDelegate.array_radios.count; //Contains 10 elements in the array_radios
} 

if (tableView == self.presets_tv) {
    return appDelegate.array_presets.count; //Contains 30 elements in the array_radios
}
}

Here is my cellForAtRowIndex

   // Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

static NSString *CellIdentifier = @"Cell";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}

// Configure the cell...
// Set up the cell
MyAppAppDelegate *appDelegate = (MyAppAppDelegate *)[[UIApplication sharedApplication] delegate];
if (tableView == radios_tv) { //radio_tv is an IBOutleet UITableView
    sqlClass *aRadio = (sqlClass *)[appDelegate.array_radios objectAtIndex:indexPath.row];
    [cell setText:aRadio.r_name];
    return cell;
}
    if (tableView == presets_tv) { //preset_tv is an IBOutlet UITableView

    }

}

Can you help me please.

I hope I didn't misunderstand you here but.

Why don't you specify a different delegate for every UITableView? I'm assuming you're using something like "radios_tv.delegate = self" when you're also doing "presets_tv.delegate = self".

You'd have to use different actual delegate objects. Maybe you could create a new class from NSObject conforming to the UITableViewProtocol, instantiate them in your view controller and assign them as delegates respectively when creating the table views.
