问题 I'm trying to display an Activity Indicator View in my app to users while a url is being loaded into a WebView. I've tried toying with activity.startAnimating/activity.stopAnimating and tried placing them in functions, etc. but have not had any luck. The best I have been able to get is the Activity Indicator to appear and animate, but then not stop animating or hide once my url is loaded, so it continues spinning on top of the web page. In other situations, when trying to move around activity

UIActivityIndicatorView not showing until after loading done

阅读更多关于 UIActivityIndicatorView not showing until after loading done

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 unlikely to make work), or a way to load the pictures after the indicator has appeared, or a way to

I have added a refresh UIBarButtonItem to my navigation bar on my iPhone app. When the user taps the button I'd like the refresh button to change to the animated activity indicator and once the operation (in this case a download) is complete switch the activity indicator back to the refresh button. I have added the refresh button using IB. Then on the button tap I create a new activity indicator and keep an pointer to the original refresh button. Like so: refreshButtonItem = self.navigationItem.leftBarButtonItem; if (activityButtonItem == nil) { activityIndicator = [[UIActivityIndicatorView

How do I put a UIActivityIndicatorView in a UIAlertController?

问题 We're moving away from MBProgressHUD because it's too glitchy in our app, and doesn't have features such as blocking user input or providing a Cancel button. So, I've attempted to implement Swipesight's How to display activity indicator in center of UIAlertController?, and I ran into improper positioning of the indicator: It is green because our app's tint is green.
