某个页面去除导航条平移手势

       因为公用一个Navigation，所以在Navigation上加了手势Pop页面 ，现针对单个页面进行手势移除如下

        id traget =self.navigationController.interactivePopGestureRecognizer.delegate;

        UIPanGestureRecognizer * pan = [[UIPanGestureRecognizeralloc]initWithTarget:tragetaction:nil];

        [view addGestureRecognizer:pan];
