Example

简单封装的下拉列表，支持多段显示

代码

创建视图

XCDropdownSegment *segment = [[XCDropdownSegment alloc] initWithFrame:CGRectMake(0, 64, SCREEN_WIDTH, SCREEN_HEIGHT-64)];
segment.dataSource = self;
segment.delegate   = self;
[self.view addSubview:segment];
    
if (1 == self.sectionCount)
{
    [segment updateConfigure:^(XCDropdownSegmentConfigure *confi) {
        confi.headerSelectedTitleColor = [UIColor redColor];
        confi.rowHeight = 40;
    }];
}

<XCDropdownSegmentDataSource.h> 数据源方法

- (NSArray<NSString *> *)titlesOfHeaderInDropdownSegment:(XCDropdownSegment *)dropdownSegment

段头标题显示的文字，可以是多段，需要一个数组返回

- (NSArray<NSString *> *)titlesOfHeaderInDropdownSegment:(XCDropdownSegment *)dropdownSegment
{
	return @[@"第一段", @"第二段", @"第三段"];
}

- (NSArray<NSString *> *)dropdownSegment:(XCDropdownSegment *)dropdownSegment titlesInSection:(NSInteger)section

每段显示的文字数组，可以根据不同的 section 来返回不同的内容

- (NSArray<NSString *> *)dropdownSegment:(XCDropdownSegment *)dropdownSegment titlesInSection:(NSInteger)section
{
    return @[
             @"三：001",
             @"三：002",
             @"三：003",
             @"三：004",
             @"三：005"
             ];
}

<XCDropdownSegmentDelegate.h> 代理方法

- (void)dropdownSegment:(XCDropdownSegment *)dropdownSegment didSelectHeaderInSection:(NSInteger)section

点击第 section 段的头部的回调

- (void)dropdownSegment:(XCDropdownSegment *)dropdownSegment didSelectRow:(NSInteger)row inSection:(NSInteger)section
