JXCategoryView的使用总结
一、初始化
-(JXCategoryTitleView *)categoryView{
if (!_categoryView) {
_categoryView = [[JXCategoryTitleView alloc] init];
_categoryView.delegate = self;
_categoryView.titleDataSource = self;
_categoryView.averageCellSpacingEnabled = NO; //是否平均分配项目之间的间距
_categoryView.contentEdgeInsetLeft = 24; //靠左显示的边距
_categoryView.titleLabelVerticalOffset = -5; //标题向上偏移
_categoryView.cellSpacing = 32; //固定分类项之前的间距
_categoryView.titles = @[];
_categoryView.defaultSelectedIndex = 0; //默认选中
_categoryView.titleColor = RGBA(119, 119, 119, 1); //默认文字颜色
_categoryView.titleSelectedColor = RGBA(51, 51, 51, 1); //文字选择颜色
_categoryView.backgroundColor = [UIColor clearColor];
_categoryView.titleFont = AppFont(16);
_categoryView.titleSelectedFont = AppBoldFont(16);
//底部指示器
JXCategoryIndicatorLineView *lineView = [[JXCategoryIndicatorLineView alloc] init];
lineView.verticalMargin = 10; //默认底部,越大越向上偏移
lineView.indicatorHeight = 3; //指示器高度
lineView.indicatorCornerRadius = 0; //是否倒圆角
lineView.indicatorColor = RGBA(72, 142, 255, 1); //指示器颜色
lineView.indicatorWidth = 24; //指示器宽度
lineView.scrollStyle = JXCategoryIndicatorScrollStyleSameAsUserScroll; //指示器滚动样式
_categoryView.indicators = @[lineView];
}
return _categoryView;
}
二、关联listContainerView
- listContainerView 创建
-(JXCategoryListContainerView *)listContainerView{
if (!_listContainerView) {
_listContainerView = [[JXCategoryListContainerView alloc] initWithType:JXCategoryListContainerType_ScrollView delegate:self];
_listContainerView.scrollView.scrollEnabled = YES;
}
return _listContainerView;
}
- 与categoryView 建立关联
self.categoryView.listContainer = self.listContainerView;
- 实现
listContainerView
代理
//子控制器数组
- (NSArray<__kindof UIViewController *> *)controllers{
return @[
self.VC1,
self.VC2,
];
}
#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;
}
//定义scrollerview处理手势冲突
- (Class)scrollViewClassInlistContainerView:(JXCategoryListContainerView *)listContainerView{
return [ServiceScrollView class];
}
三、titles 重载
可以在初始化时指定titles
属性赋值, 如果需要动态显示titles, 则可以在处理后,通过 reloadData
进行重载
- 初始化时指定
_categoryView.titles = @[@"项目1",@"项目2"];
- 动态处理
NSArray *titles;
if (xxx) {
titles = @[@"项目1",@"项目2"];
}else {
titles = @[@"礼物1",@"礼物2"];
}
_categoryView.titles = titles;
[_categoryView reloadData];
四、设置指定项被选中
[self.categoryView selectItemAtIndex:0];
五、代理方法
#pragma mark - JXCategoryViewDelegate -
//点击选中的情况才会调用该方法
- (void)categoryView:(JXCategoryBaseView *)categoryView didClickSelectedItemAtIndex:(NSInteger)index {
}
六、listContentView
需实现 listView 方法
@protocol JXCategoryListContentViewDelegate <NSObject>
/**
如果列表是VC,就返回VC.view
如果列表是View,就返回View自己
@return 返回列表视图
*/
- (UIView *)listView;
@optional
/**
可选实现,列表将要显示的时候调用
*/
- (void)listWillAppear;
/**
可选实现,列表显示的时候调用
*/
- (void)listDidAppear;
/**
可选实现,列表将要消失的时候调用
*/
- (void)listWillDisappear;
.....
根据协议声明来看, listView
方法需要协议的实现者必须 实现才可以。 因为它是 @required
(不指定,则为默认)声明的
#pragma mark - JXCategoryListContainerViewDelegate -
- (id<JXCategoryListContentViewDelegate>)listContainerView:(JXCategoryListContainerView *)listContainerView initListForIndex:(NSInteger)index{
__kindof UIViewController *vc = self.controllers[index];
return vc;
}
- (id<JXCategoryListContentViewDelegate>)listContainerView:(JXCategoryListContainerView *)listContainerView initListForIndex:(NSInteger)index
这个回调需要返回实现了 JXCategoryListContentViewDelegate
的对象(一般是viewController)
@implementation MyContentViewController
//实现 JXCategoryListContentViewDelegate 的代理方法
- (UIView *)listView{
return self.view;
}
@end
