entityMap|blocks|key|7sgo0|text|这对我在iOS+11上很有效：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5lohk|override+func+viewDidLoad()+{
++++self.tableView.refreshControl+=+refreshControl
++++self.tableView.addSubview(refreshControl)
}|code-block|syntax|javascript|4di2v|而且，您不需要显式地告诉刷新控件开始刷新，因此这就足够了：|7p3hn|func+refresh(_+sender:+Any)+{
++++Metric.sendEvent("RefreshFeed")

}|14h74|还要确保在VNetwork.getFeeds(userId)+{+feeds+in的回调中，您处于主线程上。|offset|length|style|CODE|dfts1^0|0|0|0|0|5|10|0^^$0|$]|1|@$2|3|4|5|6|7|8|S|9|@]|A|@]|B|$]]|$2|C|4|D|6|E|8|T|9|@]|A|@]|B|$F|G]]|$2|H|4|I|6|7|8|U|9|@]|A|@]|B|$]]|$2|J|4|K|6|E|8|V|9|@]|A|@]|B|$F|G]]|$2|L|4|M|6|7|8|W|9|@$N|X|O|Y|P|Q]]|A|@]|B|$]]|$2|R|4|-4|6|7|8|Z|9|@]|A|@]|B|$]]]]

This works for me on iOS 11:

<pre><code>override func viewDidLoad() {
 self.tableView.refreshControl = refreshControl
 self.tableView.addSubview(refreshControl)
}
</code></pre>

Also, you don't need to explicitly tell the refresh control to begin refreshing, so this is enough:

<pre><code>func refresh(_ sender: Any) {
 Metric.sendEvent("RefreshFeed")
 self.getFeeds(self.user.id)
}
</code></pre>

Also make sure that in the callback for <code>VNetwork.getFeeds(userId) { feeds in</code> you are on the main thread.

entityMap|blocks|key|7bb5u|text|使用self.tableView.refreshControl+=+refreshControl，您可以直接将refreshControl添加到表视图中，也不必调用self.refreshControl.beginRefreshing()|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|e7g0q|lazy+var+refreshControl:+UIRefreshControl+=+{

with <code>self.tableView.refreshControl = refreshControl</code>you can add the refreshControl directly to the tableview, also you don't have to call <code>self.refreshControl.beginRefreshing()</code>

<pre><code>lazy var refreshControl: UIRefreshControl = {
 let refreshControl = UIRefreshControl()
 refreshControl.addTarget(self, action:
 #selector(VFeedVC.refresh(_:)),
 for: .valueChanged)
 return refreshControl
}()
override func viewDidLoad() {

self.tableView.refreshControl = refreshControl
self.tableView.addSubview(refreshControl)
}
func refresh(_ sender: Any) {
 Metric.sendEvent("RefreshFeed")
 self.getFeeds(self.user.id)
}

func getFeeds(_ userId: Int) {
 VNetwork.getFeeds(userId) { feeds in
 self.feeds = feeds
 self.tableView.isHidden = self.feeds.count == 0
 self.configureCells()
 self.refreshControl.endRefreshing()
 self.tableView.reloadData()
 }
}
</code></pre>

entityMap|blocks|key|1t9k8|text|试试看，这是我的工作。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|ckp94|var+refreshControl:+UIRefreshControl!

override+func+viewDidLoad()+{
++++++++refreshControl+=+UIRefreshControl()
++++++++refreshControl.tintColor+=+UIColor.white

Try this it's work for me.

<pre><code>var refreshControl: UIRefreshControl!

override func viewDidLoad() {
 refreshControl = UIRefreshControl()
 refreshControl.tintColor = UIColor.white
 self.tblPartyList.addSubview(refreshControl)
 refreshControl.addTarget(self, action:#selector(handleRefresh(_:)), for: UIControlEvents.valueChanged)
}
@objc func handleRefresh(_ refreshControl: UIRefreshControl) {

}
</code></pre>

entityMap|blocks|key|3m9nc|text|将refreshControl.endRefreshing()放在tableView.reloadData()之后，如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4vppb|tableView.reloadData()
DispatchQueue.main.async+{
++++self.refreshControl.endRefreshing()
}|code-block|syntax|javascript|1jdg3^0|0|0^^$0|$]|1|@$2|3|4|5|6|7|8|I|9|@]|A|@]|B|$]]|$2|C|4|D|6|E|8|J|9|@]|A|@]|B|$F|G]]|$2|H|4|-4|6|7|8|K|9|@]|A|@]|B|$]]]]

Put refreshControl.endRefreshing() After tableView.reloadData() like this:

<pre><code>tableView.reloadData()
DispatchQueue.main.async {
 self.refreshControl.endRefreshing()
}
</code></pre>

The refresh wheel stops at 95% full, and the refresh will only work if from the very top of the screen you reach the bottom.

<pre><code>lazy var refreshControl: UIRefreshControl = {
 let refreshControl = UIRefreshControl()
 refreshControl.addTarget(self, action:
 #selector(VFeedVC.refresh(_:)),
 for: .valueChanged)
 return refreshControl
}()

override func viewDidLoad() {
 self.tableView.addSubview(refreshControl)
}

func refresh(_ sender: Any) {
 Metric.sendEvent("RefreshFeed")
 self.refreshControl.beginRefreshing()
 self.getFeeds(self.user.id)
}

func getFeeds(_ userId: Int) {
 VNetwork.getFeeds(userId) { feeds in
 self.feeds = feeds
 self.tableView.isHidden = self.feeds.count == 0
 self.configureCells()
 self.refreshControl.endRefreshing()
 self.tableView.reloadData()
 }
}
</code></pre>
