Question

In my app, I use a UIPopoverController and I use the presentPopoverFromRect API. What I am doing now is just setting it to the frame of my whole UISegmentedControl. However I want to be more precise than this. Is there any way to get the frame of a specific index in the UISegmentedControl?

Thanks!

Answer 1

If the segments are equal, why not just divide the width of the control by the number of the selected segment (+1 because numbering starts at 0)?
EDIT: Like this

-(void)showPopover:(id)sender {
    if ((UISegmentedControl*)sender.selectedSegmentIndex == 0)
        [self.popover presentPopoverFromRect:CGRectMake(self.segmentedControl.frame.size.width/6, self.segmentedControl.frame.origin.y, aWidth, aHeight)]
}

It’s over 6 (I’m assuming a 3 segment implementation), because you have to get the center of the segment, and 3 would put it on the lines. And if you do some simple math here (let’s assume the whole control is 60 px wide), then 60/3 yeilds 20. Because each segment is 20 px wide, the width of 60 over six yields the correct answer 10.
