Multiple UITableViews on one UIView

Question

I need to have two UITableViews on one UIView. I can make it work with one, here is the code:

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {

    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return [contentOne count];  // sets row count to number of items in array
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
    }

    NSString *firstValue = [[NSString alloc] initWithFormat: @"Row %i% %", indexPath.row+1 ];
    NSString *secondValue = [contentOne objectAtIndex:indexPath.row];

    NSString *cellValue = [firstValue stringByAppendingString: secondValue]; // appends two strings

    [cell.textLabel setText:cellValue];



    return cell;
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

}

I have tried several different methods. Anyone? If I could name each UITableView a different name that should do it but it will not let me edit tableView to anything else without crashing.

Answer 1

so you need some way to tell the two tableViews apart--you could either set the "tag" property to different values, or have a property on your view controller that points to each view

@property (nonatomic, retain) IBOutlet UITableView *tableView1;
@property (nonatomic, retain) IBOutlet UITableView *tableView2;

then hook these up to each view in interface builder...

then in your view controller methods you can do

(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    if (tableView == self.tableView1) {
        return 37;
    } else if (tableView == self.tableView2) {
        return 19;
    } else {
        // shouldn't get here, use an assert to check for this if you'd like
    }
}

Answer 2

Probably the easiest way of implementing this is to have two delegate and data source classes, one for each table view. That would reduce the number of if (tableview == tableview1) occurances in the view controller code.
