Hi all,
Does these two things mean the same?
[myObject valueForString:@"param"] == [NSNull nul] ? @"X":@"Y"
[myObject valueForString:@"param"] ? @"X":@"Y"
Thanks.

No.
First, I assume you mean -valueForKey:, not -valueForString:, plus it's +null,
not

NSBrowser is a subclass of NSControl, which happens to have a target and action
mechanism. Have you tried hooking up your browser's target and action?

Not true. A timer may fire some time after its fire date for any number of
reasons, but "no event to wake the run l

Timers will cause a runloop to fire (depending on run mode of course)
without any other source having to fire.

@interface TimerTest : NSObject
@end
@implementation TimerTest
- (void)runTest {
NSLog(@"Test Thread Running");

Here's what I got from that documentation:
- An NSTimer is a run loop source.
- NSRunLoop monitors its sources for events, provided that the run loop is
running in the mode that the source is scheduled in.
- If the run loop is processing an event from a different source and a timer
fires, then

Ah, I think this is where my brain went all funny, because the NSRunLoop
documentation mentions multiple times that "A timer is not considered an

In an NSPanel I have an NSComboBox and an NSTableView.
I make a selection in the NSComboBox , it has focus, its action method
is called.
I use the mouse wheel to scroll the table view. I click an entry in
the table view, the combo box action is called.
Correct since the combo box has focu

I have a number of BSD static libs that link with my Cocoa apps. I

Can I build BSD static libs using iPhone sdks as my base sdk?

Speaking of static libs, whatever happened to libstdc++-static.a in iOS? Some
of legacy code I'm using still seems to require it when linking. My hack-o
solution is to keep dragging the old (I think from XCode 3.1) static libs along
for the simulator and device sysroots.
