为什么要写这么简单的东西呢？因为以后每个APP启动这是一个必须功能，总结出来后面就不用每个应用都去重新写

实现代码
import UIKit
let kPrivacyState = "kPrivacyState"
class WTPrivacyDialogViewController: UIViewController {
private var checkBtn: UIButton!
var actionBlock: ((Int) -> ())?
override func viewDidLoad() {
super.viewDidLoad()
view.backgroundColor = UIColor(red: 0, green: 0, blue: 0, alpha: 0.75)
setupUI()
}
func setupUI() {
let contentView = UIView()
contentView.backgroundColor = .white
contentView.layer.cornerRadius = 8
contentView.layer.masksToBounds = true
view.addSubview(contentView)
let titleLb = UILabel()
titleLb.text = "隐私条款提示"
titleLb.font = UIFont.boldSystemFont(ofSize: 18)
contentView.addSubview(titleLb)
let style = NSMutableParagraphStyle()
style.lineSpacing = 5
let aStr = NSMutableAttributedString(string: "为了更好的保护您的权益，同时遵守相关督管要求，我们将通过《隐私政策》向您说明我们会如何搜集、存储、保护和使用您的信息。", attributes: [NSAttributedString.Key.font : UIFont.systemFont(ofSize: 14), NSAttributedString.Key.foregroundColor : RGBA(r: 102, g: 102, b: 102, a: 1), NSAttributedString.Key.paragraphStyle: style])
let subtitleLb = UILabel()
subtitleLb.numberOfLines = 0
subtitleLb.textColor = RGBA(r: 102, g: 102, b: 102, a: 1)
subtitleLb.attributedText = aStr
subtitleLb.textAlignment = .center
contentView.addSubview(subtitleLb)
let button = UIButton(type:.custom)
button.setImage(UIImage(named: "checkbox-blank-circle-line"), for: .normal)
button.setImage(UIImage(named: "checkbox-circle-line"), for: .selected)
button.addTarget(self, action:#selector(checkAction(_:)), for:.touchUpInside)
checkBtn = button
contentView.addSubview(checkBtn)
let agreeStr = NSMutableAttributedString(string: "已查看并同意《隐私政策》", attributes: [NSAttributedString.Key.font : UIFont.systemFont(ofSize: 14), NSAttributedString.Key.foregroundColor : RGBA(r: 102, g: 102, b: 102, a: 1)])
agreeStr.yy_setTextHighlight(NSRange(location: 6, length: 6), color: .blue, backgroundColor: .clear) { containerView, text, range, rect in
let vc = WTPrivacyContentViewController()
vc.title = "隐私政策"
let nav = UINavigationController(rootViewController: vc)
self.present(nav, animated: false, completion: nil)
}
let agreeLb = YYLabel()
agreeLb.attributedText = agreeStr
contentView.addSubview(agreeLb)
let agreeBtn = UIButton(type: .custom)
agreeBtn.setTitle("同意", for: .normal)
agreeBtn.setTitleColor(.white, for: .normal)
agreeBtn.backgroundColor = .blue
agreeBtn.layer.cornerRadius = 18
agreeBtn.layer.masksToBounds = true
agreeBtn.addTarget(self, action:#selector(agreeAction(_:)), for:.touchUpInside)
contentView.addSubview(agreeBtn)
let regectBtn = UIButton(type: .custom)
regectBtn.addTarget(self, action:#selector(regectAction(_:)), for:.touchUpInside)
regectBtn.setTitle("不同意并退出app", for: .normal)
regectBtn.setTitleColor(.blue, for: .normal)
contentView.addSubview(regectBtn)
contentView.snp_makeConstraints { make in
make.centerY.equalTo(view)
make.right.equalTo(-20)
make.left.equalTo(20)
make.bottom.equalTo(regectBtn.snp_bottom).offset(24)
}
titleLb.snp_makeConstraints { make in
make.centerX.equalTo(contentView)
make.top.equalTo(20)
make.height.equalTo(26)
}
subtitleLb.snp_makeConstraints { make in
make.top.equalTo(titleLb.snp_bottom).offset(8)
make.right.equalTo(-24)
make.left.equalTo(24)
make.height.greaterThanOrEqualTo(60)
}
checkBtn.snp_makeConstraints { make in
make.top.equalTo(subtitleLb.snp_bottom).offset(24)
make.left.equalTo(24)
make.size.equalTo(CGSize(width: 20, height: 20))
}
agreeLb.snp_makeConstraints { make in
make.centerY.equalTo(checkBtn)
make.height.equalTo(20)
make.left.equalTo(checkBtn.snp_right).offset(2)
}
agreeBtn.snp_makeConstraints { make in
make.top.equalTo(checkBtn.snp_bottom).offset(20)
make.height.equalTo(36)
make.right.equalTo(-24)
make.left.equalTo(24)
}
regectBtn.snp_makeConstraints { make in
make.top.equalTo(agreeBtn.snp_bottom).offset(12)
make.height.equalTo(22)
make.centerX.equalTo(agreeBtn)
}
}
@objc func checkAction(_ button:UIButton){
button.isSelected = !button.isSelected
}
@objc func agreeAction(_ button:UIButton){
if !checkBtn.isSelected {
let hub = MBProgressHUD(view: view)
hub?.mode = .text
hub?.labelText = "请先勾选并同意隐私政策"
view.addSubview(hub!)
hub?.show(animated: true, whileExecuting: {
sleep(1)
}, completionBlock: {
hub?.removeFromSuperview()
})
return
}
UserDefaults.standard.setValue(true, forKey: kPrivacyState)
if let block = actionBlock {
block(0)
}
self.dismiss(animated: true, completion: nil)
}
@objc func regectAction(_ button:UIButton){
// 可以增加再次确认在退出
exit(0)
}
}
弹出隐私条款更新
let vc = IRCPrivacyDialogViewController()
vc.modalTransitionStyle = .crossDissolve
vc.modalPresentationStyle = .custom
vc.actionBlock = {index in
print("点击了按钮\(index)")
}
self.present(vc, animated: false, completion: nil)
小问题
这里遇到一个小问题，就是弹框中点击隐私政策后跳转问题
我这里使用prsent一个UINavigationController
let vc = WTPrivacyContentViewController()
vc.title = "隐私政策"
let nav = UINavigationController(rootViewController: vc)
self.present(nav, animated: false, completion: nil)
使用这种方式可以保持和原有导航栏一致，需要注意在WTPrivacyContentViewController中需要自定义返回按钮，使用dismiss方式返回
let goback = UIButton(type: .custom)
goback.setImage(UIImage(named: "goback_dark"), for: .normal)
goback.frame = CGRect(x: 0, y: 0, width: 32, height: 32)
goback.contentHorizontalAlignment = .left
goback.addTarget(self, action: #selector(backAction), for: .touchUpInside)
self.navigationItem.leftBarButtonItem = UIBarButtonItem(customView: goback)
@objc func backAction() {
if self.navigationController?.viewControllers.count > 1 {
self.popViewController(animated: true)
} else {
self.dismiss(animated: true, completion: nil)
}
}
其实代码实现还是没有xib实现快，看个人喜好吧，喜欢纯代码的就纯代码，喜欢xib的就用xib
我是大自然的搬砖工，希望能够帮到你，谢谢~
