1,首先在项目里导入KKColorListPicker的源码(整个文件夹,在项目上有键“Add Files To XXX”).
2,手工创建桥接头文件bridge.h来包含需要引用的Objective-C头文件,内容如下:
//KKColorsSchemeType.h已经包含在KKColorListViewController.h
#import "KKColorListViewController.h"
#import "KKColor.h"
3,选择项目,在Build Setting -> Swift Compiler-Code generation -> Objective-C Bridging Header设置里添加bridge.h,如下图所示:
(直接把bridge.h拖进去)

import UIKit
class ViewController: UIViewController,KKColorListViewControllerDelegate {
var viewColor:KKColorListViewController!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
//初始化颜色选择面板
//这个颜色选择面板是用OC开发,我们导入头文件后就能在Swift里调用了
viewColor = KKColorListViewController(schemeType:KKColorsSchemeType.crayola)
//此类实现了颜色选择面板的代理协议,并重载了选择颜色和关闭2个回调函数
viewColor.delegate = self
//创建一个按钮
let button:UIButton = UIButton(type: .system)
//设置按钮位置和大小
button.frame=CGRect(x: 10, y: 50, width: 100, height: 30)
//设置按钮文字
button.setTitle("选择背景色", for:UIControlState.normal)
button.addTarget(self, action: #selector(btnClick(_ :)), for: .touchUpInside)
self.view.addSubview(button);
}
func btnClick(_ :UIButton)
{
//显示颜色选择面板
self.present(viewColor, animated: true, completion: nil)
}
func colorListController(_ controller:KKColorListViewController,didSelect color:KKColor)

//关闭颜色选择器视图

//用户在颜色选择器视图里点击了关闭
func colorListPickerDidComplete(_ controller:KKColorListViewController)
