The replacement I've seen for checking whether the current queue is "correct"
for the code in which it's running looks something like this (for a complete
implementation example, see GCDAsyncSocket):
static char *kMYObjectIsOnItsOwnQueueKey = "Whatever":
- (instancetype)init
{
if ((self = [super init])) {
// ...
_myQueue = dispatch_queue_create(...);
dispatch_queue_set_specific(_myQueue,
kMYObjectIsOnItsOwnQueueKey, (__bridge void *)self, NULL);
}
return self;
}
- (BOOL)isExecutingOnMyQueue
{
return dispatch_get_specific(kMYObjectIsOnItsOwnQueueKey) == (__bridge
void *)self;
}
