iOS 手势冲突（JXCategoryView 滚动手势与侧滑）

此处我使用的是 FDFullscreenPopGesture
解决后的效果图

在这里插入图片描述

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

/**
 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 UICollectionView 在里面实现手势的控制，让它兼容多种手势共存

1、新建 HJCollectionView 继承自 UICollectionView, 添加UIGestureRecognizerDelegate 代理

HJCollectionView.h

@interface HJCollectionView : UICollectionView<UIGestureRecognizerDelegate>

@end

2 .HJCollectionView.m

#import "HJCollectionView.h"

@implementation HJCollectionView

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {
    if (self.contentOffset.x <= 0) {
        return YES;
    }
    return NO;
}

@end

3. 在使用 JXCategoryView 的控制器中实现 JXCategoryListContainerViewDelegate

#import "FAMineCouponVC.h"

#import "FAMyCouponVC.h"
 
#import <HJUIKit/HJCollectionView.h>
#import <JXCategoryView/JXCategoryView.h>
   
@interface FAMineCouponVC ()<JXCategoryViewDelegate, JXCategoryListContainerViewDelegate>

@property (nonatomic, strong) NSArray *titles;
@property (nonatomic, strong) JXCategoryTitleView *categoryView;
@property (nonatomic, strong) JXCategoryListContainerView *listContainerView;

@end

@implementation FAMineCouponVC

// MARK: - 1.interface

// MARK: - 2.lift cycle
- (void)viewDidLoad {
    [super viewDidLoad];
     
    self.navigationItem.title = @"优惠劵";
     
    [self.view addSubview:self.categoryView];
    [self.categoryView mas_makeConstraints:^(MASConstraintMaker *make) {
        make.left.top.right.equalTo(self.view);
        make.height.mas_equalTo(40);
    }];
    [self.view addSubview:self.listContainerView];
    [self.listContainerView mas_makeConstraints:^(MASConstraintMaker *make) {
        make.top.equalTo(self.categoryView.mas_bottom);
        make.left.bottom.right.equalTo(self.view);
    }];
}

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];

    // 处于第一个item的时候，才允许屏幕边缘手势返回
    self.navigationController.interactivePopGestureRecognizer.enabled = (self.categoryView.selectedIndex == 0);
}

- (void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];

    // 离开页面的时候，需要恢复屏幕边缘手势，不能影响其他页面
    self.navigationController.interactivePopGestureRecognizer.enabled = YES;
}
// MARK: - 3.private methods
 
// MARK: - 4.event response

// MARK: - 5.getter
// 分页菜单视图
- (NSArray *)titles {
    return @[@"未使用", @"已使用", @"已过期"];
}

- (JXCategoryTitleView *)categoryView {
    if (!_categoryView) {
        JXCategoryTitleView * newView = [[JXCategoryTitleView alloc] init];
        newView.titleColor = RGBC(85);
        newView.titleSelectedColor = KTextColor;
        newView.delegate = self;
        newView.titles = self.titles;
        // !!!: 将列表容器视图关联到 categoryView
        newView.listContainer = self.listContainerView;
        
        JXCategoryIndicatorLineView * lineView = [[JXCategoryIndicatorLineView alloc] init];
        lineView.indicatorColor = KTextColor;
        lineView.indicatorWidth = 27;
        newView.indicators = @[lineView];
        
        _categoryView = newView;
    }
    return _categoryView;
} 
 
// 列表容器视图
- (JXCategoryListContainerView *)listContainerView {
    if (!_listContainerView) {
        JXCategoryListContainerView * newView = [[JXCategoryListContainerView alloc] initWithType:JXCategoryListContainerType_CollectionView delegate:self];
        _listContainerView = newView;
    }
    return _listContainerView;
}
// MARK: - JXCategoryViewDelegate
- (void)categoryView:(JXCategoryBaseView *)categoryView didSelectedItemAtIndex:(NSInteger)index {
    NSLog(@"%@", NSStringFromSelector(_cmd));
    
    // 侧滑手势处理
    self.navigationController.interactivePopGestureRecognizer.enabled = (index == 0);
}

// MARK: - JXCategoryListContainerViewDelegate
- (NSInteger)numberOfListsInlistContainerView:(JXCategoryListContainerView *)listContainerView {
    return self.titles.count;
}
// MARK: JXCategoryListContentViewDelegate
- (id<JXCategoryListContentViewDelegate>)listContainerView:(JXCategoryListContainerView *)listContainerView initListForIndex:(NSInteger)index {
    FAMyCouponVC * list = [[FAMyCouponVC alloc] init];
    list.status = index;
    return list;
}

- (Class)scrollViewClassInlistContainerView:(JXCategoryListContainerView *)listContainerView {
    return [HJCollectionView class];
}

@end

4.在子viewController中实现 jx的代理方法，也就是我上面的FAMyCouponVC

// MARK: JXCategoryListContentViewDelegate
- (UIView *)listView {
    return self.view;
}
