uiactivityindicatorview

I have an annoying problem with displaying UITableViewCell with UIActivityIndicatorView inside. My tableView delegate loads portions of data. The last cell always indicates loading process while new portion is not loaded. Loading starts in tableView: willDisplayCell: forRowAtIndexPath: .So in iOS 5 (or iOS 5 simulator) it works perfectly, but in iOS 6 (or iOS 6 simulator) UIActivityIndicatorView displays only for the first time. Maybe something was deprecated since iOS 6 or it's iOS 6 bug? Here is my dataSource: - (UITableViewCell*)tableView:(UITableView*)tableView cellForRowAtIndexPath:

How would I go about showing an activity Indicator and a white background while the data in my collectionView loads? I currently have this: let activityView = UIActivityIndicatorView(activityIndicatorStyle: .whiteLarge) override func viewDidAppear(_ animated: Bool) { super.viewDidAppear(animated) self.view.addSubview(activityView) activityView.hidesWhenStopped = true activityView.center = self.view.center activityView.startAnimating() DispatchQueue.global(qos: DispatchQoS.QoSClass.background).async { fetchPosts() } DispatchQueue.main.async { UIView.animate(withDuration: 1, delay: 1,

I am trying to manage the activity indicator from my App Delegate, that way any of my views can put the indicator up. So, I am adding it as a subview to 'window' and start/stop as follows: - (void)didStartActivity { if( activityIndicator == nil ) { activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge]; activityIndicator.hidesWhenStopped = YES; activityIndicator.center = window.center; activityIndicator.transform = CGAffineTransformScale(CGAffineTransformIdentity, 6.0, 6.0); } NSLog(@"%s: starting the activityIndicator", _

I'm playing with some JSON parsing in iOS and i wanted to add a spinner, this works wel but i can't stop the spinner and i would like to understand why. [spinner stopAnimating] is called in the async block and i believe thats where the problem is, maybe because i can't call the method on spinner in the block? i've logged the spinner obj and the output is: <UIActivityIndicatorView: 0x76905f0; frame = (150 230; 20 20); layer = <CALayer: 0x768ffb0>> Maybe somebody can make me understand how to deal with this async methods in objective-c. I'm a absolute beginner. The code: - (void)viewDidLoad{

I'm getting this warning for every nib file that contains a UIActivityIndicator . The warning states: Unsupported Configuration: Hides when stopped but is neither hidden or animating What am i doing wrong? This means, You have set Hides when stopped . So there must be two states only, Hidden Animating But you have set neither Hidden nor Animating. See the image: It must be Hidden or Animating , If you have Checked Hides when stopped . You have selected hide when stopped option but you are never hiding activityindicator. set you setting as in attached image 来源： https://stackoverflow.com

Well, I am looking for a way to change my spinner image and use a custom image Any suggestion? I have created a subclass of UIActivityIndicatorView that allows you to set a custom image. Felix Lamouroux You could simply use a UIImageView and add an animation that rotates the view's layer indefinitely. You can achieve this using CoreAnimation. There are plenty of tutorials for this out there. If you wish to start and stop the animation you can create a simple subclass of UIImageView that adds and removes said animation. Here's a link for the animation: Basic keyframe animation (rotation) 来源：

How can I get an indication to main UI thread in an iPhone app IOS program, when background task has completed? Background I'm trying to setup a loading indicator per the concept at How to add a UIActivityIndicator to a splash screen in a iphone application? was going to in AppDelete use "performSelectorInBackground" to load up the model data what I need therefore is in the RootViewController some way of telling when the data has finished loading in the background so that it can (a) update the tableview with the data and (b) remove any activity indicator I'm assuming way to do things here is
