<div class =“post-text”itemprop =“text”>
  <P>
    你可以试试这个
  </p>
   <pre>
    <code>
      let str = "the email"

if str[str.count - 7] == "a"
{
    perform segueway? for aol.com
}
else if str[str.count - 9] == "g"
     {
         perform segueway? for gmail.com
}
else
{
     perform segueway? default?
}

</code>
  </pre>
  <P>
    你需要添加这个扩展名
  </p>
   <pre>
    <code>
      extension String {

var length: Int {
    return count
}

subscript (i: Int) -> String {
    return self[i ..< i + 1]
}

func substring(fromIndex: Int) -> String {
    return self[min(fromIndex, length) ..< length]
}

func substring(toIndex: Int) -> String {
    return self[0 ..< max(0, toIndex)]
}

subscript (r: Range<Int>) -> String {
    let range = Range(uncheckedBounds: (lower: max(0, min(length, r.lowerBound)),
                                        upper: min(length, max(0, r.upperBound))))
    let start = index(startIndex, offsetBy: range.lowerBound)
    let end = index(start, offsetBy: range.upperBound - range.lowerBound)
    return String(self[start ..< end])
}

}
