ScrollView UIRefreshControl没有调用函数

Question

我在iOS 10的swift 3中向滚动视图添加了refreshControl，但是未调用添加的函数。

这是我的代码。

let rc = UIRefreshControl()
rc.addTarget(self, action: #selector(refresh), for: UIControlEvents.valueChanged)
if #available(iOS 10.0, *) {
    scrollView.refreshControl = rc
}

...

@objc func refresh(_ sender: AnyObject) {
    let response = serverHelper.send(word: JSONParser.getAllGamesForPlayer(player: localPlayer))
    let games = JSONParser.parseToArrayDic(string: response)
    print("All games \(games)")
    addAllGameButtons(games: games)
    sender.endRefreshing()
}

I want that the refreshContol is calling the refresh function. But the function is never called. What I'm doing wrong here?

EDIT

The refreshControl is working, but the problem is, that I have to scroll down to the end of the screen so that the function gets called. My scrollView has a high of 1200 px. Anyone who knows how to solve this?

当我的视图控制器size: freeform在故事板上的像素为1500px 时，我遇到了这个错误。当我将其更改为固定大小并推断时，刷新开始按预期工作。

看起来像是苹果方面的错误，刷新控件，值更改距离是在从Xib / Storyboard加载视图时设置的，但在为设备布局时未更新。
