converting NSTimer running not on main runloop to GCD
- by Justin Galzic
I have a task that runs periodically and it was originally designed to run on a separate run loop than the main runloop using NSThread and NSTimer.
What's the best way to adapt this to take advantage of GCD?
Current code:
-(void)initiateSomeTask
{
[NSThread detachNewThreadSelector:@selector(startTimerTask)
toTarget:self withObject:nil];
}
-(void)startTimerTask
{
// We won't get back the main runloop since we're on a new thread
NSRunLoop *myRunLoop = [NSRunLoop currentRunLoop];
NSPort *myPort = [NSMachPort port];
[myRunLoop addPort:myPort forMode:NSDefaultRunLoopMode];
NSTimer *myTimer = [NSTimer timerWithTimeInterval:10 /* seconds */
target:self selector:@selector(doMyTaskMethod)
userInfo:nil repeats:YES];
[myRunLoop addTimer:myTimer forMode:NSRunLoopCommonModes];
[myRunLoop run];
}
Is there anything I can do besides replace detachNewThreadSelector with dispatch_async?
