Remove UISegmentedControl separators completely. (iphone)

Question

Is there a way to completely remove the line separating the two segments in a UISegmentedControl?

Setting the segmentedControlStyle is not helping.

Answer 1

You can remove all background, border and separators from a UISegmentedControl by setting a black image. Or you can set custom colours.

The below example removes all borders/seperators, and sets the background to be white with 0.2 alpha, and the selected segment to be white with alpha 1.0

[self.segmentedControl setBackgroundImage:[self imageWithColor:[UIColor colorWithWhite:1.0 alpha:0.2]] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
[self.segmentedControl setBackgroundImage:[self imageWithColor:[UIColor colorWithWhite:1.0 alpha:1.0]] forState:UIControlStateSelected  barMetrics:UIBarMetricsDefault];

- (UIImage *)imageWithColor:(UIColor *)color {
    CGRect rect = CGRectMake(0.0f, 0.0f, 1.0f, 1.0f);
    UIGraphicsBeginImageContext(rect.size);
    CGContextRef context = UIGraphicsGetCurrentContext();

    CGContextSetFillColorWithColor(context, [color CGColor]);
    CGContextFillRect(context, rect);

    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return image;
}
