Question

I’m pretty new to multithreaded programming & cocoa.

I’m going to need a lock to access/modify a NSMutableArray iVar. What’s the simpliest way to do it ?

And while I’m here, do you guys have some reading about multithreaded programming with Obj-c/Cocoa ?
Thx.

Answer 1

Using the @synchronized block:

@synchronized(MyArray)
{
    // thread safe code
}

This block is not recognized by Xcode at times, but trust me, it works!
