IOS UIActivityViewController分享内容

基本分享

        //设定分享内容
        let textShare = "text"
        let imageShare = UIImage(named: "aaa")
        let urlShare = URL(string: "http://www.baidu.com")
        let activityItems = [textShare,imageShare as Any,urlShare as Any]
        //弹出分享框
        let activityViewController = UIActivityViewController(activityItems: activityItems, applicationActivities:nil)
        present(activityViewController, animated: true, completion: nil)
        //分享结束后的回调
        activityViewController.completionWithItemsHandler = {(_ activityType: UIActivityType?, _ completed: Bool, _ returnedItems: [Any]?, _ activityError: Error?) -> Void in
            print(completed ? "成功" : "失败")
        }
        /**

UIActivityViewController分享到不同服务都有一定的局限性，比如说facebook无法分享文本且图片和url不能同时分享

自定义分享

新建一个类继承UIActivity并重写以下方法

import UIKit

class CustomActicity: UIActivity {
    
    //分享的标题
    override var activityTitle: String?{
        return "标题"
    }
    
    //分享的LOGO
    override var activityImage: UIImage?{
        return UIImage.init(named: "aaa")
    }

    //提供的服务类型的标识符
    override var activityType: UIActivityType?{
        return UIActivityType.init(CustomActicity.description())
    }
    
    //分享类型 .action .share
    override class var activityCategory: UIActivityCategory {
        return .share
    }
    
    ///操作
    override func prepare(withActivityItems activityItems: [Any]) {
        print(activityItems)
    }
    ///是否允许进行分享
    override func canPerform(withActivityItems activityItems: [Any]) -> Bool {
        return true
    }
    
}

使用：

 let activityViewController = UIActivityViewController(activityItems: activityItems, applicationActivities: [CustomActicity()])
