uiactivityindicatorview

问题 I used to have a "Please wait" dialog in my app for long time. It was quite simple thing using UIActivityIndicatorView and adding it to UIAlertView . However iOS8 introduced UIAlertController . Is it possible to add anything to it to have similiar effect? Is there another way of doing such thing with iOS8? I have searched a lot of sites and still have no idea how it can be done with the new API. I would appreciate any answers - links to libs, tutorials etc., which could be helpful. Regards,

问题 I have a button on the currently navigated to viewcontroller, connected to an IBAction. In the IBAction I create a UIActivityIndicatorView as usual, with [self.view addSubView], then load some pictures. I've tried setNeedsDisplay on the indicator view, the view controller, and the window, but it still loads the pictures before showing the indicator, which of course is quite useless to me. So I'm looking for a way to either force an instant redraw (which when I think a little more about it is

问题 I am trying to get my first spinner to work, and I can't seem to get it to show up on the screen. I tried dragging the UIActivityIndicatorView on the storyboard to my screen, but then when I tried to connect it to my header file via the storyboard, it didn't seem to respond. (what are the correct steps there?) So I did it manually. I added this line to my .h file: @property (weak, nonatomic) IBOutlet UIActivityIndicatorView *aSpinner; and then I added these lines to my .m file

问题 i didn't really know how to title this question, but here's a thing that really kills me: In my app i have a UITableView, UISegmentedControl and UINavigationBar. Once UISegmentedControl gets one of its segments selected i want to show a UIActivityIndicatorView on the UINavigationBar and then parse an xml file and present the results in a table. Everything works almost as i want it to, except one thing, the activity indicator view gets added to the uinavigationbar after the parser finishes,

问题 i know this is a very common question, i read most of the questions asked in stackoverflow but still couldn't figure out how to remove the uiactivityindicatorview from the view. please find below the code @implementation FeedBackViewController @synthesize m_activity,webView; -(void)viewDidLoad{ [super viewDidLoad]; [webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://equinox.library.pitt.edu/limesurvey/index.php?sid=87435&lang=en"]]]; } - (void)dealloc { [m_activity

问题 In my main code(in order to show UIActivityIndicatorView) I'm calling a function, foo() on a background thread. What happens to the functions called by foo() in turn? Will those functions also be called and executed in the same background thread? 回答1: Yes, it will also be called in that same background thread. It's actually pretty easy: everything you call will be run in the same thread as the caller, unless you explicitly use methods to create a new thread and run a method there or cause a

问题 I have a view controller with an UIActivityIndicatorView, and a button which triggers synchronisation. Synchronisation is performed in a separate class, usually in the background. The synchronisation can be triggered from different parts of my app, and my view controller is notified of the synchronisation events. Now, when I click the button, the UIActivityIndicatorView does not become visible nor animated. Here is my code in viewDiDLoad: self.syncNowActivityIndicatorView.hidesWhenStopped =
