实现以上红框内的效果，设置部分字体内容的颜色为红色，前面按钮可以点击，红色字体内容也可以点击：
1、导入YYText：
import YYText
2、定义YYLabel属性
var protocolLabel = YYLabel()
3、代码实现
func initUI() {
self.protocolLabel.font = UIFont.systemFont(ofSize: 12.0)
self.protocolLabel.textColor = UIColor.init(rgb: 0x161616)
self.protocolLabel.textAlignment = .center
self.protocolLabel.isUserInteractionEnabled = true
view.addSubview(self.protocolLabel)
self.protocolLabel.snp.makeConstraints { (make) in
make.top.equalTo(vercodeUnderLineView.snp.bottom).offset(15.cgFloat.pad(20).adaptHeight())
make.left.equalTo(vercodeUnderLineView)
make.right.equalToSuperview().offset(-45.cgFloat.pad(-211).adaptWidth())
}
self.protocolLabel.numberOfLines = 2
//设置协议
setAttribute(markup: "《AI美照馆用户协议及隐私政策》")
}
//MARK:设置协议
func setAttribute(markup:String) {
let iconImg =UIButton()
iconImg.setImage(UIImage(named:"ic_radio button_nor"), for: .normal)
iconImg.setImage(UIImage(named:"ic_radio button_nsel"), for: .selected)
iconImg.hitEdgeInsets=UIEdgeInsets(top:20, left:20, bottom:20, right:20)
//MARK:设置按钮点击事件
iconImg.rx.tap.subscribe(onNext: {_in
iconImg.isSelected=!iconImg.isSelected
}).disposed(by: disposeBag)
iconImg.frame=CGRect(x:0, y:0, width:15, height:15)
letatt =YYTextAttachment(content: iconImg)
att.contentMode= .left
lettext =String(format:" 点击登录即代表同意%@",markup)
let attributeStr =NSMutableAttributedString.yy_attachmentString(withContent: iconImg, contentMode: .left, attachmentSize:CGSize(width:15, height:15), alignTo:UIFont.systemFont(ofSize:12), alignment: .center)
attributeStr.yy_insertString(text, at:1)
//MARK:设置协议点击事件
attributeStr.yy_setTextHighlight(NSRange(location:11, length: markup.count), color:UIColor.init(rgb:0xF76F00), backgroundColor:nil) { (view, att, range, rect)in
print("跳转协议")
}
self.protocolLabel.attributedText = attributeStr
}
