AttributedStringWrapper

AttributedStringWrapper is a simple packaging for NSAttributedString to make the developers easy to use 

Overview

AttributedStringWrapper is base on String extension, converted into RawRepresentable protocal in order to solve the question of Objective-C namespace. So it looks a bit strange, if you have a better way, please contact me

extension UILabel {
    convenience init(frame: CGRect = .zero, attributedText: String, textColor: UIColor, font: UIFont, lineSpacing: CGFloat) {
        self.init(frame: frame)
        let paragraphStyle = NSMutableParagraphStyle()
        paragraphStyle.lineSpacing = lineSpacing
        paragraphStyle.lineBreakMode = .byTruncatingTail
        let attrStr = NSAttributedString(string: attributedText, attributes: [NSParagraphStyleAttributeName: paragraphStyle,
                                                                              NSFontAttributeName: font,
                                                                              NSForegroundColorAttributeName: textColor])

        let attr = NSMutableAttributedString(string: content)
        let paragrap = NSParagraphStyle()
        paragrap.lineSpacing = 8.0
        paragrap.alignment = .center
        attr.addAttributes([NSParagraphStyle: paragrap], range: NSMakeRange(0, attr.length))

        shadow.shadowColor = UIColor.red
        shadow.shadowOffset = CGSize(width: 3, height: 3)

        attr.addAttributes([NSShadowAttributeName: NSShadow], range: NSMakeRange(0, attr.length))
        label6.attributedText = attr

After:

// 1. shadow: you can set range, default allRange
label1.attributedText = content.toAttributed.shadow {
    $0.shadowColor = UIColor.red
    $0.shadowOffset = CGSize(width: 3, height: 3)

// 2. paragraphStyle: you can set range, default allRange

let attrText2 = content.toAttributed.paragraph {
    $0.alignment = .center
    $0.lineSpacing = 8.0
}.font(UIFont.systemFont(ofSize: 15))

label2.attributedText = attrText2.rawValue
print(attrText2.getHeight(by: screenW - 20))


// 3. underLine:  you can set range, default allRange
label3.attributedText = content.toAttributed.underLine(style: [.styleDouble, .patternDot], color: UIColor.red).rawValue

// 4. font, foregroundColor
textField.attributedPlaceholder = "Please enter the phone number".toAttributed.font(.systemFont(ofSize: 15))
                                                                 .foregroundColor(.red).rawValue

// 5. Even you can do it
label6.attributedText = content.toAttributed
            .underLine(style: [.styleSingle, .patternDot], color: .red, range: NSMakeRange(0, 5))
            .font(.systemFont(ofSize: 18), range: NSMakeRange(5, 5))
            .backgroundColor(.blue, range: NSMakeRange(10, 5))
            .foregroundColor(.purple, range: NSMakeRange(15, 5))
            .baselineOffset(value: 5, range: NSMakeRange(20, 5))
            .obliqueness(angle: 0.5, range: NSMakeRange(25, 5))
            .kern(padding: 0.3, range: NSMakeRange(30, 5))
            .expansion(value: 0.3, range: NSMakeRange(35, 5))
            .stroke(color: .green, width: 3, range: NSMakeRange(40, 5))
            .textEffect(range: NSMakeRange(50, 5))
            .shadow{
                $0.shadowColor = UIColor.red
                $0.shadowOffset = CGSize(width: 3, height: 3)
                $0.shadowBlurRadius = 2.0
            }.rawValue

// 6. “+”
label7.attributedText = ("昵称: ".toAttributed.font(UIFont.systemFont(ofSize: 18)).foregroundColor(UIColor.red) +
                         "loopeer".toAttributed.font(UIFont.systemFont(ofSize: 13)).underLine(style: [.styleSingle])).rawValue
