Thanks! This helped me a lot. I love how simple most things are with Cocoa, but they’re not always easy to find for the first time.

This is awesome. I’m going to redirect the log file to my webserver directory and remotely view it on another machine.

No more sucky Xcode 4 console window.

Comment on Performing a block of code on a given thread by Alan Bird

Since I’m using this with iOS without ARC, I made the following change to automatically handle the autorelease pool in background threads:

+ (void)MCSM_performBlockInBackground:(void (^)())block{
[NSThread performSelectorInBackground:@selector(MCSM_runBlockInBackground:)
withObject:[[block copy] autorelease]];
}

+ (void)MCSM_runBlockInBackground:(void (^)())block{
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
block();
[pool release];
}

Thank you very much. This is one of the most useful tips I’ve seen in a long time!

Comment on Retrieving the currently being played music track by Spencer MacDonald

If you cannot get the value using MPMediaItemPropertyBeatsPerMinute it means that it hasn’t been set in iTunes.

The only other way to get it would be to analyse the audio file yourself, which would be a lot of complex code.

Thanks,

I think this is quite specific to Apple though. Usually a new release is not so stable (especially when it’s a major release). Apple does a great job of maintaining a consistent software quality.

I think that they will only pick on CPU, but dropping the iPad 2 by $100 so it is a “low cost” iPad would make sense.

I wonder if we’ll see both an A6 and A5S CPU??

That would explain the rumours indicating both – although so would prototype units.

But it would allow them to create a larger differentiation between models, to have a quad-core model at the top, dual-core in the middle, and 8Gb version of the old iPad 2 at the bottom (primary use – businesses and schools who want a cheaper iPad w/out much need for personal media).
