[Tmptblview addgesturerecognizer:longpress];

[Longpress release];

[Tmptblview release];

}

How to implement long-press events

-(void) handletableviewcelllongpressed: (Uilongpressgesturerecognizer *) Gesturerecognizer {

if (gesturerecognizer.state = = Uigesturerecognizerstatebegan) {

NSLog (@ "Uigesturerecognizerstatebegan");

}

if (gesturerecognizer.state = = uigesturerecognizerstatechanged) {

NSLog (@ "uigesturerecognizerstatechanged");

}

if (gesturerecognizer.state = = uigesturerecognizerstateended) {

NSLog (@ "uigesturerecognizerstateended");

}

}
