APPLE CERCA UI Automation

- In iOS 5.0 UIPickerView doesn't send its
pickerView:didSelectRow:inComponent:delegate message due to a programatic selection. - Starting in iOS 5 beta 3, the
exclusiveTouchproperty ofUIControlhas returned to its original default value ofNO. - Returning
nilfrom thetableView:viewForHeaderInSection:method (or its footer equivalent) is no longer sufficient to hide a header. You must overridetableView:heightForHeaderInSection:and return0.0to hide a header. - In the iOS 5 beta, the
UITableViewclass has two methods to move one cell from one row to another with defined parameters. These APIs are:moveSection:toSection:moveRowAtIndexPath:toIndexPath:
- Using the
UIWebViewclass in Interface Builder, setting transparent background color is possible in iOS 5. Developers compiling against the new SDK can check their XIB for theUIWebViewtransparent setting. - In the iOS 5 beta, the
UINavigationBar,UIToolbar, andUITabBarimplementations have changed so that thedrawRect:method is not called on instances of these classes unless it is implemented in a subclass. Apps that have re-implementeddrawRect:in a category on any of these classes will find that thedrawRect:method isn't called. UIKit does link-checking to keep the method from being called in apps linked before iOS 5 but does not support this design on iOS 5 or later. Apps can either:- Use the customization API for bars that in iOS 5 and later, which is the preferred way.
- Subclass
UINavigationBar(or the other bar classes) and overridedrawRect:in the subclass.
- The
indexPathForRow:inSection:,section, androwmethods ofNSIndexPathnow useNSIntegerinstead ofNSUInteger, so that these types match with methods defined onUITableView. - We have changed the behavior of
scrollToRowAtIndexPath:atScrollPosition:animated:such thatUITableViewScrollPositionTopandUITableViewScrollPositionBottomnow adjust for the top and bottom portions of thecontentInsetproperty. - NEW: In releases prior to iOS 5.0, the
UIPopoverControllerclass would unconditionally set the autoresizing masks of view controllers which were the content view controller of the popover controller. It would also unconditionally set the autoresizing masks of the views of view controllers pushed on to aUINavigationControllerobject which was the content view controller of the popover controller.In iOS 5.0, theUIPopoverControllerclass will no longer do this for applications linked on iOS 5.0 or later. Developers should ensure that the autoresizing masks of views are set properly to allow for arbitrary resizing within any container, not just popovers. A mask of(UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight)would not be unreasonable. - The completion handler for
saveToURL:forSaveOperation:completionHandler:is now being called outside of the coordinated write block, where it used to be called inside. - FIXED: The
autosaveWithCompletionHandler:method will now only be called for period-based saves and it is safe to return without saving. Documents must save, though, if thesaveToURL:forSaveOperation:completionHandler:method is invoked.
