Change font size of UISegmentedControl

Question

Can anyone please tell me how can I change the font type and size of UISegmentedControl?

Answer 1

Here is a Swift version of the accepted answer:

Swift 3:

let font = UIFont.systemFont(ofSize: 16)
segmentedControl.setTitleTextAttributes([NSFontAttributeName: font],
                                        for: .normal)

Swift 2.2:

let font = UIFont.systemFontOfSize(16)
segmentedControl.setTitleTextAttributes([NSFontAttributeName: font], 
    forState: UIControlState.Normal)

Answer 2

XCode 8.1, Swift 3

import UIKit
class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        UISegmentedControl.appearance().setTitleTextAttributes(NSDictionary(objects: [UIFont.systemFont(ofSize: 24.0)], 
        forKeys: [NSFontAttributeName as NSCopying]) as? [AnyHashable : Any], 
        for: UIControlState.normal)
    }
}

just change the number value (ofSize: 24.0)

Answer 3

 UISegmentedControl.appearance().setTitleTextAttributes(NSDictionary(objects: [UIFont.systemFont(ofSize: 16.0)],
                                                                        forKeys: [kCTFontAttributeName as! NSCopying]) as? [AnyHashable : Any],
                                                           for: UIControlState.normal)

Answer 5

In swift 5,

let font = UIFont.systemFont(ofSize: 16)
UISegmentedControl.appearance().setTitleTextAttributes([NSAttributedString.Key.font: font], for: .normal)

Answer 6

Use the Appearance API in iOS 5.0+:

[[UISegmentedControl appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIFont fontWithName:@"STHeitiSC-Medium" size:13.0], UITextAttributeFont, nil] forState:UIControlStateNormal];
