I have this code: NSMethodSignature *ms = [ self methodSignatureForSelector: @selector(someMethod:) ]; NSInvocation *inv = [NSInvocation invocationWithMethodSignature: ms ]; [ inv retainArguments ]; [ inv setSelector: @selector(someMethod:) ]; [ inv setTarget: self ]; [ inv setArgument: &a atIndex: 2 ];
NSInvocationOperation *ivo = [ [ NSInvocationOperation alloc ] initWithInvocation: inv ]; [ self.operationQueue addOperation: ivo ]; Works fine. But the documentation says: "An operation object is responsible for calling [isCanceled] periodically and stopping itself if the method returns YES." But how do I check for "isCanceled" from within someMethod: ? Is there something like: +[ NSOperation theOperationThisCodeIsRunningIn ]? I tried (inside of someMethod:): NSThread *currentThread = [ NSThread currentThread ]; if ( [ currentThread isCancelled ] ) NSLog(@"%s Cancelled",__FUNCTION__); But this has no effect. 10.7.3 Kind regards, Gerriet. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
