Trapping for Hide Keyboard on iOS?

Yes, use a native input control (see page 70 of the 6.0 iOS release notes). When the user taps in the control the keyboard shows (or you can have it show when the control is initially created or made visible). You can specify that your keyboard has a "Done" key - hitting that will hide the keyboard and you can also trap for that (using inputReturnKey) and do whatever you need to with the contents of the control.

This creates a control (this is for a control that is used in a search feature):

local searchInputID

on showSearch
  if "searchinput" is not in iphoneControls()  then
    iphoneControlCreate "input","searchinput"
    put the result into searchInputID
    iphoneControlSet searchInputID, "rect", the rect of btn "shadowfield"
    iphoneControlSet searchInputID, "textcolor", "gray"
    iphoneControlSet searchInputID, "autofit", "true"
    iphoneControlSet searchInputID, "autoclear", "true"
    iphoneControlSet searchInputID, "clearButtonMode", "always"
    iphoneControlSet searchInputID, "borderstyle", "rounded"
    iphoneControlSet searchInputID, "autoCorrectionType", "yes"
    iphoneControlSet searchInputID, "enabled", "true"
    iphoneControlSet searchInputID, "returnKeyType", "search"
    iphoneControlSet searchInputID, "keyboardType", "search"
    iphoneControlSet searchInputID, "visible", "true"
    iphoneControlSet searchInputID, "text", "Search"
  end if	
end showsearch

Here's how you trap for the return (or "done" key):

on inputReturnKey
  if iphonecontroltarget() = "searchinput" then
    put iphoneControlGet (searchInputID, "text") into seachString -- or put it into a field in your case
    searchFor seachString -- or just store the text in a field  
  end if
end inputReturnKey

You can even do stuff when the use first focuses on the control:

on inputBeginEditing
  if iphonecontroltarget() = "searchinput" then
    iphoneControlSet searchInputID, "textcolor", "black"
  end if
end inputBeginEditing

Hope that helps.
