MultiSelectSegmentedControl - multiple selection segmented control
A subclass of UISegmentedControl that supports selection multiple segments.
No need for images - works with the builtin styles of UISegmentedControl.
Usage
Drag a UISegmentedControl into your view in Interface Builder.
Set its class to MultiSelectSegmentedControl.
Set an outlet for it, perhaps calling it something creative such as myMultiSeg.
Set the selected segments:
myMultiSeg.selectedSegmentIndexes = [NSIndexSet indexSetWithIndex:1];Get the selected segment indices:
NSIndexSet *selectedIndices = myMultiSeg.selectedSegmentIndexes;Get the selected segment titles:
NSLog(@"These items are selected: %@", [myMultiSeg.selectedSegmentTitles componentsJoinedByString:@","]);If you want to be notified of changes to the control's value, make sure your ViewController conforms to the delegate protocol:
@interface MyViewController : UIViewController <MultiSelectSegmentedControlDelegate>...and set the delegate, perhaps in your viewDidLoad method:
myMultiSeg.delegate = self;You are notified of changes through the following method:
-(void)multiSelect:(MultiSelectSegmentedControl *)multiSelectSegmentedControl didChangeValue:(BOOL)selected atIndex:(NSUInteger)index {
if (selected) {
NSLog(@"multiSelect with tag %i selected button at index: %i", multiSelectSegmentedControl.tag, index);
} else {
NSLog(@"multiSelect with tag %i deselected button at index: %i", multiSelectSegmentedControl.tag, index);
}
NSLog(@"selected: '%@'", [multiSelectSegmentedControl.selectedSegmentTitles componentsJoinedByString:@","]);
}
