1.文字底部加陰影
我們可以給UILabel加一個(gè)分類(lèi)擴(kuò)充方法
@objc
extension UILabel {
// 文字底部加陰影
@objc
func qy_bottomShadow(){
guard let text = text else {
return
}
let attrString = NSMutableAttributedString(string: text)
let shadow = NSShadow()
shadow.shadowColor = UIColor(red:0.47,green:0.41,blue:0.65,alpha:1)
shadow.shadowBlurRadius = 1
shadow.shadowOffset = CGSize(width: 0, height: 2)
let attribute: [NSAttributedString.Key : Any] = [.shadow: shadow]
attrString.addAttributes(attribute,
range: NSRange(location: 0, length: attrString.length))
attributedText = attrString
}
}
2.文字底部加陰影 + 文字描邊
@objc
extension UILabel {
// 文字底部加陰影 + 文字描邊
@objc
func qy_bottomShadowAndStroke() {
guard let text = text else {
return
}
let attrString = NSMutableAttributedString(string: text)
let shadow = NSShadow()
shadow.shadowColor = UIColor(red:0.47,green:0.41,blue:0.65,alpha:1)
shadow.shadowBlurRadius = 1
shadow.shadowOffset = CGSize(width: 0, height: 2)
let attribute: [NSAttributedString.Key : Any] = [
.shadow: shadow,
.strokeColor:UIColor(red: 0.7,green: 0.63,blue: 0.95,alpha: 1),
.strokeWidth: -6
]
attrString.addAttributes(attribute, range: NSRange(location: 0, length: attrString.length))
attributedText = attrString
}
}
