JXCategoryTitleView的使用

最近写项目，遇到了一个vc下面有多个vc 指示器可以点击切换，也可也左右滑动进行切换，解除了JXCategoryTitleView  感觉很好用；

一般要求主vc遵循JXCategoryViewDelegate、JXCategoryListContainerViewDelegate两个协议 子vc遵循JXCategoryListContentViewDelegate

必写属性

//指示器view
@property (nonatomic, strong) JXCategoryTitleView *categoryView;
//正文view
@property (nonatomic, strong) JXCategoryListContainerView *listContainerView;
//vc数组 直接添加成vc可使得代码更加简洁
@property (strong, nonatomic) NSArray <__kindof UIViewController *> *controllers;

遵循协议 则相对应的代理方法必写

#pragma mark - JXCategoryListContentViewDelegate
- (UIView *)listView{
    return self.view;
}

#pragma mark - JXCategoryListContainerViewDelegate
- (id<JXCategoryListContentViewDelegate>)listContainerView:(JXCategoryListContainerView *)listContainerView initListForIndex:(NSInteger)index{
    __kindof UIViewController *vc  = self.controllers[index];
    return vc;
}
 
- (NSInteger)numberOfListsInlistContainerView:(JXCategoryListContainerView *)listContainerView {
    return self.controllers.count;
}

#pragma mark - JXCategoryViewDelegate
// 点击选中或者滚动选中都会调用该方法。适用于只关心选中事件，不关心具体是点击还是滚动选中的。
- (void)categoryView:(JXCategoryBaseView *)categoryView didSelectedItemAtIndex:(NSInteger)index { 
    //侧滑手势处理
    self.navigationController.interactivePopGestureRecognizer.enabled = (index == 0);
}
 
- (BOOL)categoryCollectionView:(JXCategoryCollectionView *)collectionView gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {
    if (collectionView.contentOffset.x <= 0) {
        if ([otherGestureRecognizer.delegate isKindOfClass:NSClassFromString(@"_FDFullscreenPopGestureRecognizerDelegate")]) {
            return YES;
        }
    }
    return NO;
}

若需要对指示器特殊处理 则对categoryview 自行写view

#pragma mark - 懒加载
- (JXCategoryTitleView *)categoryView{
    if (!_categoryView) {
        _categoryView = [[JXCategoryTitleView alloc] init];
        _categoryView.backgroundColor = [UIColor colorWithHexString:@"#F3F3F3"];
        _categoryView.layer.cornerRadius = 16;
        _categoryView.clipsToBounds = YES;
        _categoryView.delegate = self;
        _categoryView.titles = @[@"今天",@"7天",@"30天"];
        _categoryView.defaultSelectedIndex = 0;
        _categoryView.titleSelectedColor = [UIColor colorWithHexString:@"#161619"];
        _categoryView.titleColor = [UIColor colorWithHexString:@"#A3A3A3"];
        _categoryView.titleFont = [UIFont systemFontOfSize:12 weight:UIFontWeightMedium];
 
        JXCategoryIndicatorBackgroundView *backgroundView = [[JXCategoryIndicatorBackgroundView alloc] init];
        backgroundView.size = CGSizeMake(52, 28);
        backgroundView.indicatorColor = UIColor.whiteColor;
        backgroundView.indicatorHeight = 28;
        backgroundView.indicatorWidth = 52;
        backgroundView.indicatorCornerRadius = 14;
 
        _categoryView.indicators = @[backgroundView];
        _categoryView.listContainer = self.listContainerView;
       
    }
    return _categoryView;
}
