我正在使用 JTRevealSideBarDemoV2 来实现侧面板，如 facebook 和 Path 应用程序。我已经对它进行了各种配置，只是想在这个库中再添加一个功能。我想要的是在这个库中应用手势识别器控制，就像 facebook 一样。有人可以帮忙吗？

下载这个库的链接是：- https://www.cocoacontrols.com/controls/jtrevealsidebar

谢谢！

@wattson：- 这是我为实现手势识别器添加的代码。B但它的行为非常不正常。如果您已经下载了 JTRevealSideBarDemoV2 的代码，那么您可以分析我编写的代码。

代码是：

        (void)setUpGestures{
    UIPanGestureRecognizer *panRecognizer = [[UIPanGestureRecognizer alloc] 
  initWithTarget:self action:@selector(movePanel:)];
   [panRecognizer setMinimumNumberOfTouches:1];
    [panRecognizer setMaximumNumberOfTouches:1];
    [panRecognizer setDelegate:self];

      [self.view addGestureRecognizer:panRecognizer];
      }

     -(void)movePanel:(id)sender {
        [[[(UITapGestureRecognizer*)sender view] layer] removeAllAnimations];

         CGPoint translatedPoint = [(UIPanGestureRecognizer*)sender
        translationInView:self.view];
        CGPoint velocity = [(UIPanGestureRecognizer*)sender velocityInView:[sender view]];

       if([(UIPanGestureRecognizer*)sender state] == UIGestureRecognizerStateBegan) {
    //UIView *childView = nil;

    if(velocity.x > 0) {
        if (!JTRevealedStateRight) {
             [self revealLeftSidebar:(UIPanGestureRecognizer *)sender];
        }
    } else {
        if (!JTRevealedStateLeft) {
             [self revealRightSidebar:(UIPanGestureRecognizer *)sender];
        }

    }
    // Make sure the view you're working with is front and center.
    //[self.view sendSubviewToBack:];
    [[sender view] bringSubviewToFront:[(UIPanGestureRecognizer*)sender view]];
}

if([(UIPanGestureRecognizer*)sender state] == UIGestureRecognizerStateEnded) {

    if(velocity.x > 0) {
        // NSLog(@"gesture went right");
    } else {
        // NSLog(@"gesture went left");
    }

    if (!_showPanel) {
        [self revealLeftSidebar:(UIPanGestureRecognizer *)sender];
    } else {
        if (JTRevealedStateLeft) {
            [self revealRightSidebar:(UIPanGestureRecognizer *)sender];
        }  else if (JTRevealedStateRight) {
            [self revealLeftSidebar:(UIPanGestureRecognizer *)sender];
        }
    }
}

if([(UIPanGestureRecognizer*)sender state] == UIGestureRecognizerStateChanged) {
    if(velocity.x > 0) {
        // NSLog(@"gesture went right");
    } else {
        // NSLog(@"gesture went left");
    }

    // Are you more than halfway? If so, show the panel when done dragging by setting this
      value to YES (1).
    _showPanel = abs([sender view].center.x - self.view.frame.size.width/2) > 
      self.view.frame.size.width/2;

    // Allow dragging only in x-coordinates by only updating the x-coordinate with
     translation position.
    [sender view].center = CGPointMake([sender view].center.x + translatedPoint.x, [sender
      view].center.y);
    [(UIPanGestureRecognizer*)sender setTranslation:CGPointMake(0,0) inView:self.view];

    // If you needed to check for a change in direction, you could use this code to do so.
    if(velocity.x*_preVelocity.x + velocity.y*_preVelocity.y > 0) {
        // NSLog(@"same direction");
    } else {
        // NSLog(@"opposite direction");
    }

    _preVelocity = velocity;
}

}
