Re: RunLoop and callback function

Hi Thierry,

Hmmm. You are trying to mismatch C callback with Objective-C message. You
cannot do this. This is the same thing with C++: you cannot use member
function as callback. So code the below is the way it should work:

void PowerSourcesHaveChanged(void *info)
{
NSLog(@"ca a changi...");
[(YourClassName *)info doThisPlease];
}

-(void)initializePowerSourceChanges
{
CFRunLoopSourceRef CFrls;

// Create and add RunLoopSource

// Here I pass my context instead of NULL!
CFrls =
IOPSNotificationCreateRunLoopSource(PowerSourcesHaveChanged, self);
if(CFrls) {
CFRunLoopAddSource(CFRunLoopGetCurrent(), CFrls,
kCFRunLoopDefaultMode);
CFRelease(CFrls);
}
}

Eric
