I have a number of UITextField objects inside a (subclass of) UIView, which is
the content view for a (subclass of) UIScrollView.
When the user types into a text field, I dynamically change its size if
necessary and reset the content size of the content view. When needed, I also
scroll so that a rectangle matching the typing position of the active text
field is visible in the scroll area. So far, so good.
When the content size is larger than the visible space and the user moves to an
empty UITextField to type, the display scrolls right and left on each
character. The problem is that scrollRectToVisible:: is being called from a
UIFieldEditor object with a rectangle that is the size of the entire content
area rather than anything related to the current field or the location where
characters are being entered.
Here's a bit of the traceback:
#0 -[MultiLineScrollView scrollRectToVisible:animated:] (self=0x4d2b810,
_cmd=0x6cddd5, rect={origin = {x = 0, y = 0}, size = {width = 1119, height =
740}}, animated=1 '\001')
#1 0x0035dd84 in -[UIFieldEditor scrollSelectionToVisible:] ()
#2 0x0035bc18 in -[UIFieldEditor webViewDidChange:] ()
#3 0x0001f6c1 in _nsnote_callback ()
#4 0x00d84f99 in __CFXNotificationPost_old ()
#5 0x00d0433a in _CFXNotificationPostNotification ()
#6 0x00015266 in -[NSNotificationCenter postNotificationName:object:userInfo:]
()
#7 0x00d1d67d in __invoking___ ()
#8 0x00d1d551 in -[NSInvocation invoke] ()
#9 0x0211982a in SendDelegateMessage ()
#10 0x01f6636f in WebEditorClient::respondToChangedContents ()
#11 0x02166fdc in WebCore::Editor::appliedEditing ()
I suppose I could set up a flag to ignore the call if I've already scrolled the
current text field or if the height suggests that it's *not* a text field, but
I'm interested in finding a way to handle this that isn't fighting with the
framework if at all possible.
(Also, strictly out of curiosity, what are WebCore, WebView, and
WebEditorClient things doing in a
UITextField?)_______________________________________________
