Question

I am created two buttons that are right next to each other to mimic a segmented control. I am doing this to customize the appearance beyond what the UIKit allows. I decided to use the selected property to keep a button pressed. I have two images that one for each state normal and selected.

The problem is that when I select a button, the button highlights and turns dark, because of the hightlight state. I decided to use the selected image for the highlight state too, but it flashes, any ideas or suggestions.

- (void)leftSegmentPressed:(id)sender
{
    if ([sender isSelected]) {
        [sender setSelected:NO];
    }
    else {
        [sender setSelected:YES];
    }
}

Answer 1

For the “selected” button, disable it and manually switch the image for the state.

- (void) viewDidLoad
{
    [rightSegmentButton setImage:[UIImage imageNamed:@"unselected.png"] forState:UIControlStateNormal];
    [rightSegmentButton setImage:[UIImage imageNamed:@"selected.png"] forState:UIControlStateDisabled];
    [leftSegmentButton setImage:[UIImage imageNamed:@"unselected.png"] forState:UIControlStateNormal];
    [leftSegmentButton setImage:[UIImage imageNamed:@"selected.png"] forState:UIControlStateDisabled];
}

- (void)leftSegmentPressed:(id)sender
{
    sender.enabled = NO;
    rightSegmentButton.enabled = YES;
}

- (void)rightSegmentPressed:(id)sender
{
    sender.enabled = NO;
    leftSegmentButton.enabled = YES;
}
