iOS Question [Solved] textview links

[monic]

I'm using a TextView and trying to put a hyperlink in the view it works perfect when used on iphone 5c iOS 10 but I've tested it on a iPhone 7 and its not working.

Are their any additional steps that are needed in later builds of iOS?

Sub Linkify(tv As TextView)
   Dim no As NativeObject = tv
   no.SetField("editable", False)
   no.SetField("dataDetectorTypes", 0xffffffff)
End Sub

Example:

May I suggest an alternative ?

Have a look at this https://www.b4x.com/android/forum/threads/csbuilder-attributedstrings-builder.79153/ and the section on "Clickable links"

Also, I might be stating the obvious but look at https://www.b4x.com/android/forum/threads/ats-app-transport-security.74281/ - You could have a problem here also (Especially with HTTP vs HTTPS in your link)

Enjoy.

Hi thanks for your fast suggestion the csbuilder would solve the issue of making the links clickable but not detectable the field
dataDetectorTypes must have changed between versions?

The ATS isn't a issue in the project i just made a small example to show the issue between different versions.

I used below code

Dim cs As CSBuilder
cs.Initialize
cs.Alignment("ALIGN_RIGHT")
cs    =    Miniature.MarkPatternCSbuilder(lbldesc,cs,lbldesc.Text,1)
lbldesc.AttributedText    =    cs.PopAll

Sub MarkPatternCSbuilder(Textview2 As TextView,CS As CSBuilder,Input As String, GroupNumber As Int) As CSBuilder
   
   Pattern   =   "((([a-zA-Z0-9\~\!\@\#\$\%\^\&\*\(\)_\-\=\+\\\/\?\.\:\;\'\,])+)|(http(s)?://([\w+?\.\w+])+([a-zA-Z0-9\~\!\@\#\$\%\^\&\*\(\)_\-\=\+\\\/\?\.\:\;\'\,\s]*)?))"
   
   Dim lastMatchEnd As Int = 0
   Dim m As Matcher = Regex.Matcher(Pattern, Input)
   
   Do While m.Find
       
       Dim currentStart As Int = m.GetStart(GroupNumber)
       Dim temp As String
       temp   =   Input.SubString2(lastMatchEnd, currentStart)
       CS.Append(temp)
       lastMatchEnd = m.GetEnd(GroupNumber)

       Dim temp As String
       temp   =   m.Group(GroupNumber)
       
       If Regex.IsMatch("(http(s)?://([\w+?\.\w+])+([a-zA-Z0-9\~\!\@\#\$\%\^\&\*\(\)_\-\=\+\\\/\?\.\:\;\'\,]*)?)",temp) Then
           CS.Color(Colors.RGB(91,35,179))
           CS.Alignment("ALIGN_LEFT")
           CS.Link(temp)
           CS.Append(temp)
           CS.Pop.Pop
       
       Else If Regex.IsMatch("([a-zA-Z0-9\~\!\@\#\$\%\^\&\*\(\)_\-\=\+\\\/\?\.\:\;\'\,\s])+",temp) Then
           CS.Color(Textview2.TextColor)
           CS.Font(Textview2.Font)
           CS.Alignment("ALIGN_LEFT")
           CS.Append(temp)
           CS.Pop.Pop
           
       Else
           CS.Color(Textview2.TextColor)
           CS.Font(Textview2.Font)
           CS.Alignment("ALIGN_RIGHT")
           CS.Append(temp)
           CS.Pop.Pop
           
       End If
   Loop
   
   If lastMatchEnd < Input.Length Then
       CS.Font(Textview2.Font)
       CS.Append(Input.SubString(lastMatchEnd)).Pop
   End If
   
   Return CS
   
End Sub

The most inconsistent thing is the original code snippet works on the simulator using latest iOS but not the real device.

As written above you should use CSBuilder.

Code to find all links and mark them: https://www.b4x.com/android/forum/threads/hyperlink-click-capture.92468/#post-584854

Note that in B4i you need to use non-editable TextView.
