I want to make a Bold/Underline/Italic toolbar like you see on Pages (iPhone/iPad). They use what appears to be a UISegmentedControl.
But they can have both Bold/Underline selected at the same time, which doesn't seem to be possible with the current UISegmentedControl. The closest thing I can find is "momentary", which makes the UISegmentedControl like a button array.
The NSSegmentedControl (Mac version) seems to have this ability by setting [cell setTrackingMode:NSSegmentSwitchTrackingSelectAny]. It also has NSSegmentSwitchTrackingMomentary, similar to UISegmentedControl (which uses a BOOL).
Is there a way to sub-class the UISegmentedControl to add this ability? Is there any good third party toolbars controls that do this? What Apple's Pages doing?
