iOS Question [Solved] Need help converting Swift code to B4i Native Object.

[LWGShane]

Swift Code:

var messageVC = MFMessageComposeviewController()
messageVC.body = b
messageVC.recipients = r
messageVC.messageComposeDelegate = self;
self.presentViewController(messageVC, animation: false, completion: nill)

NativeObject Code:

Sub Class_Globals
    Private MC As NativeObject
    Private ThePage As Page
End Sub

'Initializes the object. You can add parameters to this method if needed.
Public Sub Initialize (P As Page)
    ThePage = P
End Sub

Public Sub CreateMessage (TNumber As String, TMessage As String)
    MC.Initialize("MFMessageComposeViewController")
    MC.SetField("body", TMessage)
    MC.SetField("recipients", TNumber)
End Sub

Public Sub ShowDialog
    MC.SetField("messageComposeDelegate", ThePage)
    Dim PNO As NativeObject = ThePage
    PNO.RunMethod("presentViewController", Array(MC, False, Null))
End Sub

However, when I run this, I get the following error:

Spoiler: Error

You should use MessageComposer from the iPhone library.

@Erel - Thank you. I didn't realize the Phone library had those built in.

However, out of curiosity, how would I set fields like "body" with NativeObject? I would like to know just to have the knowledge.

It should have been:

MC = MC.Initialize("MFMessageComposeViewController").RunMethod("new")
