实现了大部分Path 2.0 特效
注（iOS5 only），文章最后有源码下载
tableview添加手势检测代码

 

- (void)awakeFromNib{

 UIPanGestureRecognizer* recognizer;

    // handleSwipeFrom 是偵測到手势，所要呼叫的方法

    recognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(handlePanFrom:)];

    // 不同的 Recognizer 有不同的实体变数

    // 例如 SwipeGesture 可以指定方向

    // 而 TapGesture 則可以指定次數

    //recognizer.direction = UISwipeGestureRecognizerDirectionLeft | UISwipeGestureRecognizerDirectionRight;

    recognizer.delegate = self;

    [_tableView addGestureRecognizer:recognizer];

    [recognizer release];

}

 

- (BOOL)gestureRecognizerShouldBegin:(UIPanGestureRecognizer *)gestureRecognizer

{

    CGPoint translation = [gestureRecognizer translationInView:[[UIApplication sharedApplication] keyWindow]];

     

    // Check for horizontal gesture

    if (sqrt(translation.x * translation.x) / sqrt(translation.y * translation.y) > 1)

    {

        return YES;

    }

     

    return NO;

}

 

- (void)handlePanFrom:(UIPanGestureRecognizer*)recognizer {

 

    if (recognizer.state == UIGestureRecognizerStateBegan) {

        ;

    }

    else if (recognizer.state == UIGestureRecognizerStateChanged) {

        CGFloat xOffSet = [recognizer translationInView:[[UIApplication sharedApplication] keyWindow]].x;

         

        AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];

        if (xOffSet < 0) {

            [appDelegate makeRightViewVisible];

        }

        else if (xOffSet > 0) {

            [appDelegate makeLeftViewVisible];

        }

         

        self.navigationController.view.frame = CGRectMake(xOffSet,

                                                          self.navigationController.view.frame.origin.y,

                                                          self.navigationController.view.frame.size.width,

    }

    else if (recognizer.state == UIGestureRecognizerStateEnded) {

        if (self.navigationController.view.frame.origin.x < -kTriggerOffSet)

            [self moveToLeftSide];

        // animate to right side

        else if (self.navigationController.view.frame.origin.x > kTriggerOffSet)
