iOS Question Absolute position of view

[daxydoggie]

Hi,

Is there an iOS (or B4i) version of https://www.b4x.com/android/forum/t...ates-of-view-using-getlocationonscreen.54020/ in order to find the location of a view in relation to the visible page/screen (not its parent).

Thanks,
Craig.

You can use this code:

Sub GetPageLeftAndTop(v As View) As Float()
   Dim tl(2) As Float
   Do While GetType(v) <> "B4IMainView"
     Dim no As NativeObject = v
     tl(0) = tl(0) + v.Left
     tl(1) = tl(1) + v.Top
     v = no.GetField("superview")
   Loop
   Return tl
End Sub

Dim LeftTop() As Float = GetPageLeftAndTop(Button1)
Log($"Left: ${LeftTop(0)} Top: ${LeftTop(1)}"$)
