Question

I got a simple question :

In a tableView, i’m displaying a list of customCells. These cells contain labels, SegmentedControllers….

The labels, segmentedController and other cells attributes are declared in a specific class.

How could I, in the class where the list it updated, detect if the segmented controller of the cells are modified? In this class, when I do something like :

if (cell.segmentedControl == 1) { DO MY THINGS }

…nothing ever happens.

Has anybody an advice? 🙂

First of all, I’m pretty sure you need to use

(cell.segmentedControl.selectedSegmentIndex == 1)

with regards to knowing when it’s been changed, use an IBAction connected to your cell class, set up a delegate on your view controller that will get a call back from the cell class when a cell control is clicked.

EDIT ———————–
In your cell’s class .h add

@property (nonatomic, weak) id<NSObject> delegate;

In the cell’s class .m

@synthesize delegate = _delegate;

- (IBAction)segmentControlChanged
{
    if ([self.delegate respondsToSelector:@selector(segmentChanged:)]) {
        [self.delegate performSelector:@selector(segmentChanged:) withObject:self];
    }
}

In your ViewController that has the table, in the cellForRowAtIndexPath method, add

cellname.delegate = self

and add the method

-(void)segmentChanged {
  // Put code here to refresh your data source
[self.tableView reloadData];
}
