self.navigationController.interactivePopGestureRecognizer.enabled = YES;

如果手动定制了返回按钮，这个功能将会失效，也就是自定义了navigationItem的leftBarButtonItem，那么这个手势就会失效。

1.重新设置手势的delegate

self.navigationController.interactivePopGestureRecognizer.delegate = (id)self;

实现代理

- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer

{

//关闭主界面的右滑返回

if (self.navigationController.viewControllers.count == 1)

{

return NO;

}

else

{

return YES;

}

}

2.当然你也可以自己响应这个手势的事件

[self.navigationController.interactivePopGestureRecognizer addTarget:self action:@selector(handleGesture:)];
