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
UIScrollView * guidePageView= [[UIScrollView alloc]initWithFrame:[UIScreen mainScreen].bounds];
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
