A beautiful and easy-to-use progress HUD for your iOS.

Hello, I'm facing an issue with progress hud, it would run second time in any VC and hang the app on a physical device. but seems fine in the simulator.

Simulator: iPhone 7 iOS 13 Device: iPhone 7 iOS 13

I use KRProgressHUD.show(withMessage: "Loading...") to show a loading indicator, but occasionally the loading indicator (spinner) is not displayed .Ref image. Reproduced in iOS 10 devices .

Hi, on api call I'm showing loader and on success I'm showing Success view but its not getting display, I tried too many times. Xcode version - 11 pod version - 3.4.2

Not compile with Xcode 10 Swift 4.2 DeplymentTarget iOS 10.0 Cocoapods 1.5.3

Errors: /Users/.../Pods/KRActivityIndicatorView/KRActivityIndicatorView/Classes/KRActivityIndicatorView.swift:111:62: 'kCAMediaTimingFunctionLinear' has been renamed to 'CAMediaTimingFunctionName.linear' /QuartzCore.kCAMediaTimingFunctionLinear:3:12: 'kCAMediaTimingFunctionLinear' was obsoleted in Swift 3

Hi, fist of all thank you very much for KRActivityIndicator. it's work fine and very nice activity indicator. but while keyboard is open and show indicator, app is going crash.

Thanks Jaymin Patel.

I tried the KTProgressHUD with good internet connection and slow internet connection. And I'm putting the loader before making the API call. And in good internet connection, the loader is showing perfectly. But in low internet connection, the screen gets freezes but loader is not showing. Can you please help me this?

I have a UITabBarController with more than 5 controllers inside it, which in result puts some of them under the special "More" menu item:

And if one of these controllers hidden under "More" calls for example KRProgressHUD.show(withMessage: "test") the app will crash with EXC_BAD_ACCESS:

While controllers outside of "More" work as expected.

Tested on the iPhone 6 with iOS 11.2.2 KRProgressHUD version: 3.2.0

Hello,

Thank you for your work on this pod :)

I'm currently using it to show that the application is calling a REST server so I usually begin() the spinner and when I get the reply from the server I dismiss() it.

However, I have some specific situations where the REST call can be avoided and thus, what I end up doing is begin() the spinner and, a bit down the code, I dismiss it.

What ends up happening is that the spinner goes away but the white box where it spins (and the whole dark layer) don't disappear.

Any idea is this is a bug or if I'm doing something incorrectly.

(ultimately I could devise some logic to stop showing the spinner in the first place but I would like to avoid that, if possible).

Thank you1

There is only one problem with your library. What if I just want to lock a specific ViewController with the ProgressHUD? E.g.: If I have a TabBarController that I can navigate through the tabs. Currently your library only supports showing in fullscreen mode, locking all the windows bellow it. Do you think that supporting presentation in a ViewController based root would be a good idea? If yes, I'm thinking about creating a pull request. :)

After some digging through your code, I found that you have a sharedView() class func, but somehow i cannot call it by KRProgressHUD.sharedView(). Therefore, I don't see any ways to move the view.

Hi, When I using library 'SwiftPasscodeLock'(I take passcode lock presenter from there) HUD is not showing. Can you help me figure out why?

My AppDelegate where I have PinCodeLockPresenter class.

Hi.

When i dismiss KRProgressHUD the rootViewController is still set to KRProgressHUDViewController. Is there any work-around to inherit my old value before setting it? If I check the dismiss method this is done: if self.presentingViewController != nil { self.hudViewController.willMove(toParent: nil) self.hudViewController.view.removeFromSuperview() self.hudViewController.removeFromParent() self.presentingViewController = nil self.window.rootViewController = self.hudViewController }

so at the end the rootViewController is set again to self.hudViewController.

If some UIAlertView is added while ProgressHUD is loading. after that if we call KRProgressHUD.dismiss() than it will also dismiss the default UIAlertView

I have tab bar and for each view controller i have to show progress but it only work on first view controller . i am using KRProgressHUD.showOn(self).show() for each view controller but its not working.

Hello I'm using this code KRProgressHUD.set(duration: 2).set(font: fontRegular(size: 14)).showInfo(withMessage: "Error")

but only show message once and not working again
