Change border color of UISegmentedControl

Question

I need different border colour for both the sections.By default I am having white as border color.

Can anyone help me out with this?

Answer 1

A simple solution:

//Set default tint color. This will set text color and border color
[[UISegmentedControl appearance] setTintColor:[UIColor whiteColot]];
// Set background image for normal and selected state. This will appear on top of the border and cover the actual border.
[[UISegmentedControl appearance] setBackgroundImage:[UIImage imageNamed:@"btn-blue-shade-1"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
[[UISegmentedControl appearance] setBackgroundImage:[UIImage imageNamed:@"btn-blue-shade-2"] forState:UIControlStateSelected barMetrics:UIBarMetricsDefault];

try this

segment.layer.borderColor = [UIColor colorWithRed:<#(CGFloat)#> green:<#(CGFloat)#> blue:<#(CGFloat)#> alpha:<#(CGFloat)#>];
segment.layer.borderWidth = 1.0f;
segment.layer.cornerRadius = 5.0f;

In swift try this:

class MySegmentedControl: UISegmentedControl{

    override func awakeFromNib() {
       super.awakeFromNib()
       for selectView in subviews{
            selectView.layer.borderColor = borderColor?.CGColor
            selectView.layer.borderWidth = CGFloat(borderWidth)
            selectView.layer.cornerRadius = CGFloat(cornerRadius)
            selectView.layer.masksToBounds = true
       }
    }

}

its because, each Segment is a View, you can custom it However you want

Extension method code for the Segment Control.

This is working code with Latest Swift 3.0 [March 2017]

The Extension method is created, as the extension to the native segment control.

extension UISegmentedControl {
    func setSegmentStyle() {

        let segmentGrayColor = UIColor(red: 0.889415, green: 0.889436, blue:0.889424, alpha: 1.0 )

        setBackgroundImage(imageWithColor(color: backgroundColor!), for: .normal, barMetrics: .default)
        setBackgroundImage(imageWithColor(color: tintColor!), for: .selected, barMetrics: .default)
        setDividerImage(imageWithColor(color: segmentGrayColor), forLeftSegmentState: .normal, rightSegmentState: .normal, barMetrics: .default)
        let segAttributes: NSDictionary = [
        NSForegroundColorAttributeName: UIColor.gray,
        NSFontAttributeName: UIFont(name: "Merriweather-Regular", size: 14)!
    ]
        setTitleTextAttributes(segAttributes as [NSObject : AnyObject], for: UIControlState.normal)
        let segAttributesExtra: NSDictionary = [
        NSForegroundColorAttributeName: UIColor.white,
        NSFontAttributeName: UIFont(name: "Merriweather-Regular", size: 14)!
    ]
        setTitleTextAttributes(segAttributesExtra as [NSObject : AnyObject], for: UIControlState.selected)
        selectedSegmentIndex = -1
        self.layer.borderWidth = 1.0
        self.layer.cornerRadius = 5.0
        self.layer.borderColor = segmentGrayColor.cgColor
        self.layer.masksToBounds = true
    }

// create a 1x1 image with this color
    private func imageWithColor(color: UIColor) -> UIImage {
        let rect = CGRect(x: 0.0, y: 0.0, width:  1.0, height: 1.0)
        UIGraphicsBeginImageContext(rect.size)
        let context = UIGraphicsGetCurrentContext()
        context!.setFillColor(color.cgColor);
        context!.fill(rect);
        let image = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();
        return image!
    }
}

This extension can be used in anywhere of code where the UIsegment control is used.

myUISegment.setSegmentStyle()

This will apply all the styles that are applied to the segment control.

Note: Here in this sample I have removed default border, changed font, set different colors during normal , Selected mode, border explicitly made some colors.

Based on your requirement and colors you can change accordingly as green or any customized color which also shown in sample "segmentGrayColor"

Try like this.

NSArray *arri = [segment subviews];

// Change the tintColor of each subview within the array:

[[arri objectAtIndex:0] setTintColor:[UIColor redColor]];

[[arri objectAtIndex:1] setTintColor:[UIColor greenColor]];
