Nick try to put the fillMode property of the animation also
something like
alphaAnimation.fillMode = kCAFillModeForwards;
and removeOnCompletion to NO;
no matter what key you put when adding the animation to the layer, the imprtant
is the key you use when creating the animation, so "opacity"
Great that did the trick :-)

My view is "backed layered" - the checkbox "Needs CA Layer" is selected for
both the main view of the window, and for this theView.

Chase,
thank you for your responses.
I actually tested both your code and the code of Gustavo. For me the result
was the same - the opacity changes back to 1.0 when the animation had
finished and then i hide it, which still causes blinking...
Before the animation starts, i need to set the opacity

Did you try making that change in your code? If yes, is your view layer
backed?
I work mainly on iOS so I could be missing something but the code worked
without blinking for me on 10.6.
What is happening, as I think I understand it, is that by setting the opacity
of your view's layer to 0.
In your Xcode text window, hold down the option key and double click on
NSString. You will be given the option of viewing an overview of the
class. Click on the icon in the upper right side of the window that looks
like a book. This will show you a view of the documentation for NSString.
When l
Chase,
the animation itself worked and works - either with your code or with
Gustavo's.
But after the animation finishes, the opaqueness of the view again becomes
1.0 again. Then the "animationDidStop" gets called and the view disappears.
But before disappearing, it annoyingly blinks (so, the opaq

Change your code to look like this:

Gustavo,
thanks for the response.
Unfortunately, this idea makes the view to blink..
The view fades away, but then when alpha reaches 0.0 it becomes 1.0
(and the view becomes opaque again for a little while) and after that
the view becomes hidden as that callback is being called.

Dear Nick and all,
Thanks so much for your replies!
I have got the reason of the exception. When sending a message successfully,
SendMessage is returned without unlocking. The structure, try/catch/finally,
is a good solution to the potential problem.

Nitpick: the caller of -initWithCleanupBlock: should not be
responsible for the memory management of the block. Rather,
-initWithCleanupBlock: should copy

Dear all,
I am implementing a TCP client to send messages with BSD sockets. A BOOL
variable, isConnected, is used to detect if the TCP connection is built.
Since the client must be accessed by multiple threads, a NSLock,
isConnectedLock is used.
