分享的弹出视图
首先在需要显示的ViewController中懒加载一个JSShareView
lazy var shareVc:JSShareView = { let shareView = JSShareView.init(title: "选择分享方式", imageArray: ["share_qq","share_qzone","share_wechat","share_weibo","share_wxtimeline"], textArray: ["QQ","Qzone","Wechat","Weibo","朋友圈"]) return shareView }()
然后需要显示，调用下面的方法
self.shareVc.show()
点击的回调调用下面的方法
self.shareVc.itemClickBlock = { (index) in
print("点击了")
print(index)
}
