Using multiple UITableViews in a XIB - ios

Question

I have created a custom widget as a XIB file where I have multiple UITableViews and a UIButton. In the corresponding swift file which is the owner of this XIB, I have outlets to these TableViews.
I have added this widget to a view inside a view in a UIViewController. Now in the corresponding swift file of this controller, I need to assign dataSource and delegate to each of the tableviews, and an action to the button.
I have been looking online for long, and seems like #IBInspectable vars are the way to go, but seems like I cannot make a var which of type UITableView,UITableViewDelegate or UITableViewDatasource as #IBInspectable.
So how do I use the tableviews and the button? Can anyone direct me to the correct documentation, example, or explain?

No need to use an #IBInspectable. You can simply use each table source within the UITableViewDelegate methods conditionally. Here's one way to go about doing this:
First within your storyboard's UITableViewController, add a prototype cell, then within that prototype cell add a UITableView with its own prototype cell.
Then set both the inner and outer table view cell's reuse identifiers like so:
Outer table view cell:
Inner table view cell:
Then link that inner tableview's data source and delegate to the UITableViewController's own data source and delegate:
Then within your UITableViewController class, you can set your tables' elements conditionally, for example:
- (void)viewDidLoad {
[super viewDidLoad];
dataSource1 = [NSArray arrayWithObjects:#"1", #"2", #"3", #"4", #"5", #"6", #"7", nil];
dataSource2 = [NSArray arrayWithObjects:#"a", #"b", #"c", nil];
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
if (tableView == self.tableView) {
return 80;
} else {
return 20;
}
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
if (tableView == self.tableView) {
return dataSource1.count;
} else {
return dataSource2.count;
}
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell;
if (tableView == self.tableView) {
cell = [tableView dequeueReusableCellWithIdentifier:#"reuseIdentifier" forIndexPath:indexPath];
} else {
cell = [tableView dequeueReusableCellWithIdentifier:#"reuseIdentifier2" forIndexPath:indexPath];
}
// Configure the cell...
if (tableView == self.tableView) {
cell.textLabel.text = [dataSource1 objectAtIndex:indexPath.row];
} else {
cell.textLabel.text = [dataSource2 objectAtIndex:indexPath.row];
cell.backgroundColor = [UIColor blueColor];
}
cell.textLabel.backgroundColor = [UIColor clearColor];
return cell;
}
Which in this case produces the following result:
