iOS Code Snippet A good thing for you MarkPatternCSbuilder

Hi
I could detect link or any thing with Regex in android and use it
But in B4i i had problem about convert my custom pattern to link
Now with below code you can convert any string with pattern to link

Sub MarkPatternCSbuilder(Input As String, Pattern As String, GroupNumber As Int) As CSBuilder
   Dim cs As CSBuilder
   cs.Initialize
   Dim lastMatchEnd As Int = 0
   Dim m As Matcher = Regex.Matcher(Pattern, Input)
   Do While m.Find
       Dim currentStart As Int = m.GetStart(GroupNumber)
       cs.Append(Input.SubString2(lastMatchEnd, currentStart))
       lastMatchEnd = m.GetEnd(GroupNumber)
       'apply styling here
       cs.Color(0xFF03FFFF)
       cs.Link(m.Group(GroupNumber))
       cs.Append(m.Group(GroupNumber))
       cs.Pop.Pop 'number should match number of stylings set.
   Loop
   If lastMatchEnd < Input.Length Then cs.Append(Input.SubString(lastMatchEnd))
   Return cs
End Sub

Example for detect hashtag:
Label1.AttributedText = MarkPatternCSbuilder(Label1.Text,"\B(#\w+)\b",1)
