I have a MyOperation, subclass of NSOperation.
MyOperation does:
create an NSOperationQueue
add a few MyOperations to this queue
waitUntilAllOperationsAreFinished
(obviously this recursion stops at some point - I do not create an infinite
number of operations).
The good thing: this is very energy saving: cpu utilisation = 0%
The bad thing: nothing gets done.
Using Activity Monitor to sample my app I see:
"Dispatch Thread Soft Limit: 64 reached in 2152 of 2152 samples -- too many
dispatch threads blocked in synchronous operations"
Using trial and error, I managed to not create too many operations, so that
this blocking does not happen anymore.
But: Is there some way to find out programmatically at which point my app
should stop adding operations?
Either with NSOperationQueue or GCD.
