Hi list,
I've been tidying up a codebase which can now make use of block-based APIs and
all is working quite nicely. However, in several places I have controllers
which I want to setup and launch and then clean up when they're done. What I
used to do was like this:
- (void)startImport
{
MyImportController *controller = [[MyImportController alloc] init];
[controller setCallbackTarget:self];
[controller start];
}
- (void)importDone:(MyImportController *)aController
{
// This method called from the controller
}
But what I've changed that to is this:
MyImportController *controller = nil;
CleanupBlock cleanup = ^{
[controller release];
// Other stuff
};
controller = [[MyImportController alloc] initWithCleanupBlock:[[cleanup copy]
autorelease]];
[controller start];
// The controller calls cleanup() when it's done
It doesn't exhibit any problems that I can see, but the static analyzer
complains that I'm leaking the controller object in the second example. Am I
actually doing something wrong here? If not, is there a way to make analyzer
recognise this?
- Ben
