scrollview 中的 Refreshcontrol 在 swift 中不起作用
Refreshcontrol in scrollview is not working in swift
问:
我的观点中有一个可滚动的内容。我想在其中添加拉动以刷新。我尝试添加,但没有触发操作。
我尝试了很多方法并重新搜索,但没有一种对我有用。我将 iOS 10 作为最低部署目标。
尝试 1:
let refreshControl = UIRefreshControl()
self.scl_view.alwaysBounceVertical = true
refreshControl.addTarget(self, action: #selector(pullToRefresh(_:)), for: .valueChanged)
scl_view.addSubview(refreshControl)
尝试 2:
let refreshControl = UIRefreshControl()
self.scl_view.alwaysBounceVertical = true
refreshControl.addTarget(self, action: #selector(pullToRefresh(_:)), for: .valueChanged)
scl_view.refreshControl = refreshControl
MARK:- 刷新控制
@objc func pullToRefresh(_ refreshControl: UIRefreshControl) {
// Update your conntent here
self.setupData()
//refreshControl.endRefreshing()
}

选择 TablViewController 转到检查器 查找刷新选择已启用 转到“文档大纲”,然后选择“刷新控件” 控制拖动或右键单击(按住)拖动到控制器文件并调用函数以刷新数据
它在 TableView 上不可用

var refreshControl = UIRefreshControl()
override func viewDidLoad() {
super.viewDidLoad()
collectionView.delegate = self
collectionView.dataSource = self
// Add Refresh Control to collection View
if #available(iOS 10.0, *) {
collectionView.refreshControl = refreshControl
} else {
collectionView.addSubview(refreshControl)
}
refreshControl.tintColor = UIColor(red:0.25, green:0.72, blue:0.85, alpha:1.0)
// Configure Refresh Control
refreshControl.addTarget(self, action: #selector(fetchData(_:)), for: .valueChanged)
}
@objc private func fetchData(_ sender: Any) {
DispatchQueue.main.async {
//Fuction which you want to call
self.refreshControl.endRefreshing()
}
}
