• 🔗 iOS Example Project

Interface

is very simple!

public class HKLSegmentedControl : UISegmentedControl {

/// The object that acts as the delegate of the segmented control.
public weak var delegate: HKLSegmentedControlDelegate?

/// Current highlighted segment index you touch. If you don't touch it,
///  The value is same with that of <code>selectedSegmentIndex</code> property.
public private(set) var highlightedSegmentIndex: Int
}

public protocol HKLSegmentedControlDelegate: class {

/// Called when start touching the segmented control.
///
/// This is optional.
///
/// - Parameters:
///   - control: The HKLSegmentedControl object you touched.
///   - highlightedSegmentIndex: Current segment index you touched.
func segmentedControl(_ control:HKLSegmentedControl, didBeginTouch index:Int)


/// Called when the touched segment is changed.
///
/// This method is only called when you are touching the segmented control.
/// It is not called if you touch up it. To handle touch end event, use default "Value Changed" event.
/// This is optional.
///
/// - Parameters:
///   - control: The HKLSegmentedControl object you touched.
///   - index: Current segment index you are touching.
func segmentedControl(_ control: HKLSegmentedControl, didChangedIndex index: Int)
}

Receive update events

Use segmentedControl(_:didChangedIndex:) delegate method.

@interface ViewController () <HKLSegmentedControlDelegate>
@property (weak, nonatomic) IBOutlet HKLSegmentedControl *segment;
@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    _segment.delegate = self;
}

// Receive dynamic update events
- (void)segmentedControl:(HKLSegmentedControl *)control didChangedHighlightedIndex:(NSInteger)highlightedSegmentIndex {
    // Do anything!
}

// Can receive Value Changed(=touch up inside) event.
- (IBAction)selected:(id)sender {
}
@end
