如何开始

下载 MultipleTabs 并尝试使用包含的 iPhone/iPad 示例应用。

查看文档以全面了解 MultipleTabs 中所有可用功能。

MultipleTabs 不包含任何外部依赖项。

其他安装方式

通过 Git 克隆源代码。

将 MultipleTabs 文件夹添加到您的项目（或工作空间）中。

快速入门

导入框架

import MultipleTabs

创建一个新类并从 MultipleTabsViewController 继承

class ViewController: MultipleTabsViewController {

在 viewDidLoad 中注册您将用于每个标签的 collectionViewCells，并声明您的 dataSource MultipleTabsViewControllerDataSource

override func viewDidLoad() {
  super.viewDidLoad()
    
  register(type: Cell1.self, identifier: "Cell1")
  register(type: Cell2.self, identifier: "Cell2")
  dataSource = self
}

dataSource 应该实现 3 个回调方法

extension ViewController: MultipleTabsViewControllerDataSource {
  
  /// The number of tabs you want
  func numberOfTabs() -> Int {
    return 2
  }
  
  /// The title for each tab
  func title(forTabIndex index: Int) -> String {
    return "Title"
  }
  
  /// Return the container cell you want for the tabIndex
  func cell(forTabIndex index: Int) -> UICollectionViewCell {
    
    let cell: UICollectionViewCell
    
    if index == 0 {
      cell = dequeue(identifier: "Cell1", index: index)
    }
    else {
      cell = dequeue(identifier: "Cell2", index: index)
    }
    
    return cell
  }
}

定制

有一些可供定制的选项，但所有这些都具有默认值

  /// The height for the titles bar
  public var titlesHeight: CGFloat = 50
  
  /// The color for the bottom selected border of the tab
  public var titleBorderColor: UIColor = .black
  
  /// The height for the bottom selected border of the tab
  public var titleBorderHeight: CGFloat = 5
  
  /// The color for the title label when selected
  public var titleSelectedColor: UIColor = .black
  
  /// The color for the title label when unselected
  public var titleUnselectedColor: UIColor = .darkGray
  
  /// The font for the title label when selected
  public var titleSelectedFont: UIFont = .boldSystemFont(ofSize: 14)
  
  /// The font for the title label when unselected
  public var titleUnselectedFont: UIFont = .systemFont(ofSize: 14)
  
  /// The multiplier for the size of the bottom selected border compared of the width of the tab title
  public var borderWidthMultiplier: CGFloat = 0.8

其他

有一些其他 dataSource 回调可用

  /// Called just before cell will be displayed
  @objc optional func willDisplay(cell: UICollectionViewCell, forTabIndex index: Int)
  
  /// Called just after cell has been displayed
  @objc optional func didEndDisplaying(cell: UICollectionViewCell, forTabIndex index: Int)

要求

• MultipleTabs 与 iOS 9 及更高版本兼容。
• MultipleTabs 使用自动引用计数（ARC）。
• 包含在源代码中的示例应用需要 iOS 9。
