100% agree with you, and that's what i would normally do. But
unfortunately, this time i must wait in the mainthread for the

Then use a while loop to run the runloop until your callback's been
invoked. The reason this is described as wrong is because it blocks
the main thread; but if you have to block the main thread, this is
the way to do it.
Excellent. I remember reading somewhere that because of changes in
10.6 to the way the runLoop works, it was a bad idea to do this. But
for now its working and until someone tells me otherwise, this'll do.
thx
According to the CFRunLoop reference (CFRunLoopRun() discussion to be
exact), it is perfectly valid to call a runloop recursively.
«Run loops can be run recursively. You can call CFRunLoopRun from
within any run loop callout and create nested run loop activations on
the current thread’s call stack.»
If you encounter any issue with this function (but look like it's not
the case), fill a radar.
