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()])
