iOS手势冲突(JXCategoryView滚动手势与侧滑、UITableView又划删除)

解决后的效果图 (待定上传)

JXCategoryListContainerViewDelegate 提供了一个可选的协议方法:

@optional
/**
 返回自定义UIScrollView或UICollectionView的Class
 某些特殊情况需要自己处理UIScrollView内部逻辑。比如项目用了FDFullscreenPopGesture,需要处理手势相关代理。

 @param listContainerView JXCategoryListContainerView
 @return 自定义UIScrollView实例
 */
- (Class)scrollViewClassInlistContainerView:(JXCategoryListContainerView *)listContainerView;

看到这个我就知道怎么弄了,咱们可以自定义一个自定义UIScrollView或UICollectionView 在里面实现手势的控制,我这里初始化[[JXCategoryListContainerView alloc] initWithType:JXCategoryListContainerType_ScrollView delegate:self]因此需要自定义一个UIScorllView来控制手势,让它兼容多种手势共存
1.ServiceScrollView.h

@interface ServiceScrollView : UIScrollView<UIGestureRecognizerDelegate>

@end

2.ServiceScrollView.m

@implementation ServiceScrollView

/**
 重载UIScrollView手势
 是否支持多手势触发,1.返回YES,则可以多个手势一起触发方法;2.返回NO则为互斥
 // called when the recognition of one of gestureRecognizer or otherGestureRecognizer would be blocked by the other
 // return YES to allow both to recognize simultaneously. the default implementation returns NO (by default no two gestures can be recognized simultaneously)
 //
 // note: returning YES is guaranteed to allow simultaneous recognition. returning NO is not guaranteed to prevent simultaneous recognition, as the other gesture's delegate may return YES
 */
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {
    if (gestureRecognizer.state != UIGestureRecognizerStatePossible) {
        return YES;
    } else {
        return NO;
    }
}

  1. 在使用JXCategoryView的控制器中实现JXCategoryListContainerViewDelegate
- (Class)scrollViewClassInlistContainerView:(JXCategoryListContainerView *)listContainerView
{
    return [ServiceScrollView class];
}
