Just watch out - as with every language, there is a lot of bad code out there. While I agree with the notion of reading others' code (personally that helps me a lot to learn a new language), I'd go through the Apple-provided sample code before venturing into code of random apps.

Unfortunately, much of the Apple sample code is also pretty terrible.

Here's one heuristic: if you see any Objective C++ files (*.mm) in the project, you can probably ignore it as an example of good style.

Disagree. Some good libraries are C++, so linking to them requires you to use Obj-C++ (at very least, changing the name to *.mm).

Yeah, I meant things like sample code for plain C frameworks, where the author has just decided "hey, why not do this in Obj-C++ instead of Obj-C." As I recall, many of the AudioToolbox examples are like this.

Didn't mean to imply that there's no place for Obj-C++, just that it's not good style if you don't actually need it (like to wrap a C++ lib).

The number of iOS examples using Objective-C++ is pretty minimal, IIRC.
