Swift5.0|Swift5.0 用正则表达式检测文本中的网页链接 Swift5.0用正则表达式检测文本中

获取方法如下：

import UIKitclass ViewController: UIViewController {override func viewDidLoad() { super.viewDidLoad()}override func touchesBegan(_ touches: Set, with event: UIEvent?) { let content = "三端拿到了卡机:\nhttp://www.baidu.com\n这是网址案件来看受打击了卡机了,dkajskldla:\n ahjahdkjhakhttp://www.baidu.com87647826478\n876238ahdkjandkanlk\nhttp://www.taobao.com这是网址\"http://www.baidu.cn\n\"卡号的快捷键啊https://www.iconfont.cn/collections/detail?cid=2301da"cj_getContentUrl(content: content) }fileprivate func cj_getContentUrl(content:String) { // 获取链接 var content = content.replacingOccurrences(of: "\n", with: "") content = (content.trimmingCharacters(in: .whitespaces)) let regulaStr = "((http[s]{0,1}|ftp)://[a-zA-Z0-9\\.\\-]+\\.([a-zA-Z]{2,4})(:\\d+)?(/[a-zA-Z0-9\\.\\-~!@#$%^&*+?:_/=<>]*)?)|(www.[a-zA-Z0-9\\.\\-]+\\.([a-zA-Z]{2,4})(:\\d+)?(/[a-zA-Z0-9\\.\\-~!@#$%^&*+?:_/=<>]*)?)" // 创建正则表达式对象 guard let regex = try?
