Ios 将边框添加到UISegmentedControl
如何将带有颜色的边框设置为Ios 将边框添加到UISegmentedControl,ios,swift,iphone,uikit,Ios,Swift,Iphone,Uikit,如何将带有颜色的边框设置为UISegmentedControl 默认情况下,我会得到以下信息(不正确): 我试过了,但什么也没发生 UISegmentedControl.appearance().layer.borderWidth=1.0 UISegmentedControl.appearance().layer.cornerRadius=5.0 UISegmentedControl.appearance().layer.borderColor=UIColor.white.cgColor UI
UISegmentedControl
默认情况下,我会得到以下信息(不正确):
我试过了,但什么也没发生
UISegmentedControl.appearance().layer.borderWidth=1.0
UISegmentedControl.appearance().layer.cornerRadius=5.0
UISegmentedControl.appearance().layer.borderColor=UIColor.white.cgColor
UISegmentedControl.appearance().layer.masksToBounds=true
我希望实现此边界(正确):
我使用此功能更改分段控件:
func setSegmentedControlStyle(_ sgControl: UISegmentedControl, withColor: UIColor, normalTextColor: UIColor, withCornorRadius: CGFloat) {
let sgcTitleAttributes = [NSAttributedString.Key.font: UIFont.nunitoSansRegularFontOfSize(15.0)!,
NSAttributedString.Key.foregroundColor: normalTextColor] as [NSAttributedString.Key : Any]
let sgcSelectedStateTitleAttributes = [NSAttributedString.Key.font: UIFont.nunitoSansRegularFontOfSize(15.0)!,
NSAttributedString.Key.foregroundColor: _WHITE_COLOR] as [NSAttributedString.Key : Any]
if #available(iOS 13.0, *) {
sgControl.backgroundColor = UIColor.clear
let tintColorImage = UIImage(color: .clear, size: CGSize(width: 1, height: sgControl.frame.height))
let selectedTintColorImage = UIImage(color: withColor, size: CGSize(width: 1, height: sgControl.frame.height))
sgControl.setBackgroundImage(tintColorImage, for: .normal, barMetrics: .default)
sgControl.setDividerImage(tintColorImage, forLeftSegmentState: .normal, rightSegmentState: .normal, barMetrics: .default)
sgControl.setBackgroundImage(selectedTintColorImage, for: .selected, barMetrics: .default)
sgControl.selectedSegmentTintColor = withColor
} else {
sgControl.tintColor = withColor
}
sgControl.layer.cornerRadius = withCornorRadius
sgControl.layer.borderWidth = 1.0
sgControl.layer.borderColor = withColor.cgColor
sgControl.layer.masksToBounds = true
sgControl.setTitleTextAttributes(sgcTitleAttributes, for: .normal)
sgControl.setTitleTextAttributes(sgcSelectedStateTitleAttributes, for: .selected)
}
extension UIImage {
convenience init(color: UIColor, size: CGSize) {
UIGraphicsBeginImageContextWithOptions(size, false, 1)
color.set()
let ctx = UIGraphicsGetCurrentContext()!
ctx.fill(CGRect(origin: .zero, size: size))
let image = UIGraphicsGetImageFromCurrentImageContext()!
UIGraphicsEndImageContext()
self.init(data: image.pngData()!)!
}
}
你可以根据自己的需要进行调整

很乐意帮忙 当你尝试那个密码的时候,你得到了什么?@koen什么都没有发生,这并不意味着什么。您能发布正确和错误的图片吗?@koen请再次检查更新的问题,该问题看起来像是标准的
UISegmentedControl
。如何设置控件,是否可以添加该代码?这只会添加边框。是否可以添加内联边框以及前面提到的问题检查setDividerImage…创建彩色图像并将其传递到此处
