UISwipeGestureRecognizer的一些问题

今天做一个页面的  版本更新的导航显示页

层次是这样，最底下一个UIScrollView，   然后在UIScrollView  上放  uiimageView

需求是滑动到最后一页，继续往右滑动的话  就退出导航状态

用的是UISwipeGestureRecognizer  滑动状态

设置的函数一直没有调用  

后面搜了下   感觉是跟UIScrollView  的滑动冲突了 

加上代理方法

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {

    return YES; // Recognizers of this class are the first priority

}

问题就解决了   

目前理解来说   是两个空间冲突了   希望有人遇到这种情况吗   或者说出自己的看法

附上代码

imageArray为一个数组，

        "http://data.and.com.cn/image/index/1.png",

        "data.and.com.cn/image/index/2.png",

        "data.and.com.cn/image/index/3.png"

-(void)setImageArray:(NSArray *)imageArray{

    _imageArray = imageArray;

    

    //设置引导视图的scrollview

    self.guidePageView = guidePageView;

    guidePageView.userInteractionEnabled = YES;

    guidePageView.contentSize = CGSizeMake(ScreenWidth*imageArray.count, ScreenHeight);

    guidePageView.bounces = NO;

    guidePageView.pagingEnabled = YES;

    guidePageView.showsHorizontalScrollIndicator = NO;

    self.guidePageView.delegate = self;

    [self.view addSubview:guidePageView];

    

    //添加在引导视图上的多张引导图片

    for (int i=0; i<imageArray.count; i++) {

        UIImageView *imageView = [[UIImageView alloc]initWithFrame:CGRectMake(ScreenWidth*i, 0, ScreenWidth, ScreenHeight)];

//        NSData *imgData = [NSData dataWithContentsOfURL:[NSURL URLWithString:imageArray[i]]]; //得到图像数据

        }else{

        }

        [self.guidePageView addSubview:imageView];

        

        if (i == imageArray.count - 1) {

            imageView.userInteractionEnabled = YES;

            UISwipeGestureRecognizer *swipeGR = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipe)];

        }

    }

    

    if (imageArray.count > 1) {

        //设置引导页上的页面控制器

        UIPageControl * imagePageControl = [[UIPageControl alloc]initWithFrame:CGRectMake(0, ScreenHeight - 70, ScreenWidth, 50)];

        self.imagePageControl = imagePageControl;

        imagePageControl.currentPage = 0;

        imagePageControl.numberOfPages = imageArray.count;

        imagePageControl.pageIndicatorTintColor = [UIColor lightGrayColor];

        imagePageControl.currentPageIndicatorTintColor = [UIColor redColor];

        [self.view addSubview:self.imagePageControl];

    }

    

    UIButton * btn = [[UIButton alloc] init];

    btn.frame = CGRectMake(ScreenWidth - 65, 20, 55, 35);

    [btn setBackgroundImage:[UIImage imageNamed:@"tiaoguoicon"] forState:UIControlStateNormal];

    [btn addTarget:self action:@selector(swipe) forControlEvents:UIControlEventTouchUpInside];

    [self.view addSubview:btn];

    

}

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {

    return YES; // Recognizers of this class are the first priority

}

//最后一张图片的手势识别

-(void)swipe{

    if ([self.delegate respondsToSelector:@selector(toRootVC)]) {

        [self.delegate toRootVC];

    }

}

- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollview {

    int page = scrollview.contentOffset.x / scrollview.frame.size.width;
