I'm using NSOperationQueue's addOperationWithBlock. From within the block, how do I check to see if I'm supposed to cancel the operation? Or access any NSOperation properties/methods?
[myOperationQueue addOperationWithBlock: ^{
while ( /* long running loop */ )
{
// how to determine here if I need to cancel?
// for that matter, access any NSOperation properties/methods?
}
}];
Is the better way to do this to use a NSBlockOperation?
