我安装了testFlight,将应用程序添加到iTunes连接,然后使用testFlight下载它.我的测试应用无法连接到互联网.但如果我通过电缆上传我的应用程序 - 互联网工作.

我从网站获取数据(HTML字符串).我想提取所有链接.我写函数(它有效),但它太慢了......

你能帮我优化一下吗？我可以使用哪些标准功能？功能逻辑:在文本中找到"http:.//"sting,然后读取字符串(购买字符)直到我不会得到"\"".

extension String {

subscript (i: Int) -> Character {
    return self[advance(self.startIndex, i)]
}

subscript (i: Int) -> String {
    return String(self[i] as Character)
}

subscript (r: Range<Int>) -> String {
    return substringWithRange(Range(start: advance(startIndex, r.startIndex), end: advance(startIndex, r.endIndex)))
}}



func extractAllLinks(text:String) -> Array<String>{
var stringArray = Array<String>()
var find = "http://" as String

for (var i = countElements(find); i<countElements(text); i++)
{
    var ch:Character = text[i - Int(countElements(find))]
    if (ch == find[0])
    {
        var j = 0
        while (ch == …

我在TableViewCell上有故事板segue,我用它在单击单击didSelectRowAt方法中转移到另一个VC .现在我做了双击TapGestureRecognizer以处理细胞上的轻微敲击.问题是,单击时,segue正在执行,双击不起作用.单击单元格,双击可正常工作.到目前为止我的代码可能以某种方式解决这个问题吗？或者我需要删除segue并单独处理单击和双击.谢谢你的任何建议

    view.addGestureRecognizer(doubleTap)
}

func handleDoubleTap(recognizer: UIGestureRecognizer) {
    let p = recognizer.location(in: tableView)
