Hello,
In my app I need to determine if some app if properly codesigned. To do this I
just invoke "/usr/bin/codesign" and analyse return value. To invoke it I use
NSTask and launch it in background thread. Everything works fine excepts
strange crash I get sometimes from our customers. While NST

You're thinking of kAudioUnitProperty_MaximumFramesPerSlice
(http://developer.apple.com/library/ios/#qa/qa1606/_index.html). You have to
set that to 4096 frames per slice for every audio unit that's not the remoteIO
unit.

You'd have to guess (by reading the first few bytes of the file, seeing what
they are and how they're laid out, etc), or use the
initWithContentsOfFile:usedEncoding:error: variant to let NSString guess for
you.

Obviously, there are sometimes overlaps between encodings when you're
trying to guess.

Hi Laurent-
I have an app that collects a lot of text off the web; my string creation
algorithm is something like the following:
1. Attempt to create an NSString with NSUTF8StringEncoding.
2. If the string is nil, attempt to create the string using the encoding
returned from the server.

Hank,
I have tried with by setting "kAudioUnitProperty_MaximumFramesPerSlice"
property as 4096 for Mixer and EQ Audio Units. Now audio playback did not stop
when the device goes to sleep mode.
But i hear glitches along with Audio.
I have looked at apple sample code MixerHost. it play
I believe Audio units need 44100 Hz, but I'm not sure about that. Regardless,
decoding mp3 with an AudioConverter should not introduce any glitches at that
rate - any iOS device should be able to handle that without issues.
The 4096 is the right value for any iOS device. Without seeing your code
Hank,
I have included the key methods which decodes and renders the audio
data.
i uses the following structures to hold the data
typedef struct
{
UInt32 mDataByteSize;
UInt32 mNumOfPackets;
UInt32 mPacketOffset;
UInt32 mNumOfChannels;
UInt32 mBytesPerPacket;
char *
I though I was following a good example ... I do not get the results I expect.
I have a view controller.
To this I have added a second view and wired it up through its IBOutlet.
In viewDidLoad:
[[self view] addSubview:m_projectSelector];
m_projectSelector.hidden=NO;
When the parent view is hidden, all the stuff contained in it will be invisible
as well. So you might like to try sibling views instead of hierarchical views?

I believe I understand the difference between properties and instance
variables, and the effect of using properties as opposed to instance
variables viz a viz KVO and memory management.
What I can't understand is why you would access instance variable
Speed is generally not something to be concerned about WRT property accessors.
If you want to bypass the property accessor behavior when accessing an ivar,
then access it directly.
Somewhere in Apple's docs I read a suggestion that IBOutlets be released in
-dealloc by direct access, and release

And it's worth mentioning that you can always do @synthesize foo=_foo;

This is a wild guess but it worked for me with Core Text on the iPad a long
time ago. One or several of these can probably work for you.
