首先在加载UI的时候添加左右手势

//添加向右滑动的手势

 UISwipeGestureRecognizer *Recognizer;

    Recognizer = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(hanleSwipAction:)];

    [Recognizer setDirection:UISwipeGestureRecognizerDirectionRight];

//添加向左滑动的手势

    [self.view addGestureRecognizer:Recognizer];

    Recognizer = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(hanleSwipAction:)];

    [Recognizer setDirection:UISwipeGestureRecognizerDirectionLeft];

    [self.view addGestureRecognizer:Recognizer];

    

//滑动手势执行的动作(这里的数组模型是通过collectionView的item点击事件传入的)

-(void)hanleSwipAction:(UISwipeGestureRecognizer *)recognizer{

    if (recognizer.direction == UISwipeGestureRecognizerDirectionRight) {

        NSLog(@"向右滑动");

        if (self.curruntCount > 0) {

            self.curruntCount = self.curruntCount - 1;

            ExpertDetailPhoto *model = self.icons[self.curruntCount];

             self.pageNumLabel.text = [NSString stringWithFormat:@"%d/%lu",self.curruntCount + 1,(unsigned long)self.icons.count];

            [self.photoImageView sd_setImageWithURL:[NSURL URLWithString:model.img] placeholderImage:[UIImage imageNamed:@"ImageDefault"]];

            NSString *subtypeString;

            subtypeString = kCATransitionFromLeft;

           [self transitionWithType:@"pageCurl" WithSubtype:subtypeString ForView:self.view];

        }else{

            self.curruntCount = 0;

        }

    }else if(recognizer.direction == UISwipeGestureRecognizerDirectionLeft){

        NSLog(@"向左滑动");

        if (self.curruntCount < (int)(self.icons.count -1)) {

            self.curruntCount = self.curruntCount + 1;

            ExpertDetailPhoto *model = self.icons[self.curruntCount];

             self.pageNumLabel.text = [NSString stringWithFormat:@"%d/%lu",self.curruntCount + 1,(unsigned long)self.icons.count];

            [self.photoImageView sd_setImageWithURL:[NSURL URLWithString:model.img] placeholderImage:[UIImage imageNamed:@"ImageDefault"]];

            NSString *subtypeString;

            subtypeString = kCATransitionFromRight;

            [self transitionWithType:@"pageCurl" WithSubtype:subtypeString ForView:self.view];

        }else{

            self.curruntCount =(int)(self.icons.count - 1);

        }

    }

}

//执行动画的方法

- (void) transitionWithType:(NSString *) type WithSubtype:(NSString *) subtype ForView : (UIView *) view {

//实例化动画对象

    CATransition *animation = [CATransition animation];

//动画执行时间

    animation.duration = 0.5f;

//动画类型

    animation.type = type;

    if (subtype != nil) {

        animation.subtype = subtype;

    }

//动画执行过程效果(例:如淡进淡出)

    animation.timingFunction = UIViewAnimationOptionCurveEaseInOut;

//执行动画操作

    [view.layer addAnimation:animation forKey:@"animation"];

//view的layer层动画.

}
