For posterity, if anyone needs the answer to this, I discovered that I need to
also over-ride needsPanelToBecomeKey to return YES so that a mouse-click can
give focus to the control. I found this in the ClockControl example, I'd not
seen that method before.

Hi All,
Just curious, why does this work (compiles and runs):
displayLink = [NSClassFromString(@"CADisplayLink") displayLinkWithTarget:
tapped selector:@selector(respond:)];
But this doesn't link because the CADisplayLink class is missing:
displayLink = [CADisplayLink

Open the view that contains the matrix in IB. Then, open the matrix. The first
cell should be called "Prototype Button Cell (Radio)" or something like that.
Select that prototype cell. Select "Tools -> Identity Inspector". The class
identity lets you select which class this cell should be.

helloo. Can someone explain please, when an NSView's call -drawRect
(being called manually - not by a framework) actually initiates
redrawing of the frame and displaying everything that it had drawn,
and when this call "doesn't initiate a thing"?
in some Apple samples is see that often to display
Thank you
But there is no way to call "drawRect" manually? Maybe to call it
manually and then tell NSView that it had processed that method?
I just found out why in Apple sample code CIVideoDemoGL drawRect could
be called directly - because the drawing job was delegated to the
OpenGL, and drawn by

You may bypass the message queue by calling [theView display] but be
aware not to draw too many times.

Rather than do this, it's better to learn how the framework actually
works, and behave accordingly.
Don't fight the framework.

Hi All,
I have a RTSP stream of H.264 video and I would like to decode the video
stream. I am aware of ffmpeg but I was wondering if there are any
alternatives to decoding the stream on iOS 4.x
Thanks, Andy

After using Xcode/Obj-C/Cocoa to make an iPhone project (a custom phone-book
app for my employer), I've come to the following conclusion(s), and maybe some
of you have, also:
1) There needs to be a way to 'wrap' the .h, .m, and .xib file all into one
nice 'package' (a .xhm file, maybe?), though

Most of this doesn't have anything to do with Cocoa so I will be brief
and respond only to the relevant portions.

Are CGPDFDocument and PDFDocument toll-free bridged? If not, how can I get a
PDFDocument from a CGPDFDocumentRef?
I need to use the lower level API to extract graphic entities from a PDF, but
I'd like to use PDFKit up-front to implement a page chooser.

We have a network-dependent app that will suffer from lengthy delays if
connectivity is poor. We've found that if the user quits the app during a
long network activity, the app will often crash upon its next launch.
Why? It shouldn't be retaining any state between launches.
Thanks for any insig
