Random idea (untested, just spouting here)
What about initing a barButtonItem with a custom view (that view being a
UIButton that has the target/action set on the appropriate touch down inside
[the end zone! - sorry, couldn't resist]), and then setting the target/action

I struggled this too, but without solution. It seems that toolbar 'buttons'
aren't real buttons -- they're class UIBarButtonItem from UIBarItem from
NSObject. Since they're not really buttons, there doesn't appear any way to

That's not guaranteed to always give you the same NSData either. Maybe
it works now for your small test case, bu
Hi All.
I'm working on accessibility in an app, and would like to have a view pop up on
screen and immediately become the focused item so that its text will be spoken.
There seems to be no call to "becomeAccessibilityFocus" like there is
"becomeFirstResponder".
Is there a way to do this?
Any

I'm doing an iPhone 4.1 app and I have a toolbar at the bottom with bar
buttons. The problem is that I need to set one of the bar buttons to "Touch
Down" instead of the default "Touch Up Inside" but IB doesn't show any touch
options for toolbar buttons (it does for buttons not in the toolbar).

I have changed the contentView of my NSWindow to be a NSView which return YES
for isFlipped.
If I place a NSButton in the contentView of a window, I can do the following:
NSRect r = [view frame];
NSPoint origin;
origin = [view convertPoint:NSZeroPoint toView:[[view wind
In the array controller I added an outlet for the data source of the second
table view:
IBOutlet ZZSecondArrayController *dataSource;
and connected it to the Array Controller for the second table view.
Then I changed the line that gave the compiler warning message to:

I'm getting a compiler warning message at the following line of code:
NSArray *selectedObjects = [[secondTableView dataSource] selectedObjects
];
The warning message is <'selectedObjects' not found in protocol>.
Can someone suggest what I need to do to remove the warning?
