uirefreshcontrol

问题 I have been looking around but couldn't find anything good about this. I would like to customize the default UIRefeshControl with different loader, etc. So far I can only change tintColor & attributedTitle properties and most code I found are just basically creating a new "pulltorefresh" effect but what I want is to just use the UIRefreshControl and customize it a bit. Is this possible? 回答1: You can't add different loader without accessing private APIs, but you can add background image:

问题 In my application I use refresh control with collection view. UICollectionView *collectionView = [[UICollectionView alloc] initWithFrame:[UIScreen mainScreen].bounds]; collectionView.alwaysBounceVertical = YES; ... [self.view addSubview:collectionView]; UIRefreshControl *refreshControl = [UIRefreshControl new]; [collectionView addSubview:refreshControl]; iOS7 has some nasty bug that when you pull collection view down and don't release your finger when refreshing begins, vertical contentOffset

问题 Is it possibile add UIRefreshControl at the bottom of the UITableView ? I would use it to load more data. Please, Any suggest? 回答1: I believe there won't be any simple solution to this problem.

问题 I am trying to show a refresh control right when the view loads to show that I am getting getting data from Parse. The refresh control works as it should when the app is running, but I cannot get it to fire programmatically from anywhere in my app. This is the code that does not appear to run: override func viewDidAppear(animated: Bool) { self.refresher.beginRefreshing() } Not only does this not run, but having the code in the app changes the attributes of the refresh control. When I have

问题 In UIRefreshControl in iOS App, I think the default setting is that when I pull down UITableView(UISrollView) by about "100px", refresh begins. I would like to make the above value smaller.(for example, "50px") Is this possible? If possible, please tell me sample codes. 回答1: Try this: // definition extension UIRefreshControl { func refreshManually() { beginRefreshing() sendActions(for: .valueChanged) } } // usage var isRefreshingManually = false func scrollViewDidScroll(_ scrollView:

问题 Every time I pull to refresh the TableView, the UIRefreshControl appears to be glitchy. Below is the code I am using. Any Ideas? In AppDelegate: UINavigationBar.appearance().isTranslucent = false UINavigationBar.appearance().barTintColor = UIColor.red UINavigationBar.appearance().tintColor = UIColor.white In UITableViewController: self.tableView.refreshControl = UIRefreshControl() if #available(iOS 11.0, *) { self.navigationController?.navigationBar.prefersLargeTitles = false } else { //

问题 You can add UIRefreshControl to UICollectionView (or any UIScrollView for that matter) by adding it to collection's subviews: UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init]; [refreshControl addTarget:self action:@selector(handleRefresh:) forControlEvents:UIControlEventValueChanged]; [self.collectionView addSubview:refreshControl]; This doesn't work when collection view layout has UICollectionViewScrollDirectionHorizontal. I tried overriding layoutSubviews to put refresh

问题 I have a UIRefreshControl in a UITableViewController . Is there any way I can detect if a user begins to drag the View down to refresh the content? I do not mean the beginRefreshing method. I want to be able to detect when a user begins to drag down - like when the circle fills up before the beginRefreshing method is called. Is this possible? 回答1: As you have implemented UITableViewDelegate protocol you can also implement UIScrollViewDelegate which is called on scroll or drag. Objective C -

问题 I'd like to ask you how can I show UIActivityControl under TV cells. This is how it's showed right now. Thanks (self.tableView.refreshControl = self.refresh_control doesn't work ) Code: override func viewDidLoad() { super.viewDidLoad() self.refresh_control = UIRefreshControl() self.refresh_control.attributedTitle = NSAttributedString(string: "Aktualizace") self.refresh_control.addTarget(self, action: "refresh:", forControlEvents: UIControlEvents.ValueChanged) self.view.addSubview(self.refresh
