swift——uiwebview的使用

首先，创建一个label：

agreeDeal = UILabel()

let tap = UITapGestureRecognizer.init(target: self, action: #selector(LoginViewController.showPrivatePolicy))

agreeDeal.addGestureRecognizer(tap)

agreeDeal.userInteractionEnabled = true

//富文本,不同字体颜色大小和颜色

let labelString = NSLocalizedString("Login_agree deal", comment: "") as NSString

let rang = labelString.rangeOfString("《")

let firstRang = NSMakeRange(0, rang.location)

let secondRang = NSMakeRange(rang.location, labelString.length - rang.location)

let labelText = NSMutableAttributedString(string: labelString as String as String)

labelText.addAttributes([NSForegroundColorAttributeName:UIColor.init(white: 1, alpha: 0.8),NSFontAttributeName:UIFont.boldSystemFontOfSize(12)], range: firstRang)

labelText.addAttributes([NSForegroundColorAttributeName:UIColor.redColor(),NSFontAttributeName:UIFont.boldSystemFontOfSize(12)], range: secondRang)

agreeDeal.attributedText = labelText

agreeDeal.textAlignment = .Center

agreeDeal.numberOfLines = 0

bottomView.addSubview(agreeDeal)

agreeDeal.snp_makeConstraints { (make) in

make.centerX.equalTo(bottomView)

make.width.equalTo(kscreenWidth)

make.top.equalTo(facebookBtn.snp_bottom).offset(10)

make.height.equalTo(50)

}

跳到下一个web view的界面：

import UIKit

import MBProgressHUD

private let url = "http://www.coollang.com/appcontent/responsibility?type=6"

class PrivatePolicyController: UIViewController,NavigationBackProtocol {

@IBOutlet weak var webView: UIWebView!

override func viewDidLoad() {

super.viewDidLoad()

configureNav()

loadWeb()

}

func configureNav()

{

let titleStr = NSLocalizedString("Login_Privacy Policy", comment: "隐私政策")

title = titleStr

leftNavigationItem()

}

func loadWeb(){

let webUrl = NSURL(string: url)

let request = NSURLRequest.init(URL: webUrl!, cachePolicy: .UseProtocolCachePolicy, timeoutInterval:requestOverTime)

webView.loadRequest(request)

webView.delegate = self

}

}

extension PrivatePolicyController:UIWebViewDelegate

{

func webViewDidStartLoad(webView: UIWebView) {

MBProgressHUD.showHUDAddedTo(webView, animated: true)

}

func webViewDidFinishLoad(webView: UIWebView) {

MBProgressHUD.hideHUDForView(webView, animated: true)

}

func webView(webView: UIWebView, didFailLoadWithError error: NSError?) {

MBProgressHUD.showTextWithMessageInBottom(error?.localizedDescription ?? "")

}

}
