HUD is not working inside extensions

[ramunasjurgilas]

When using HUD inside extension (as I am using in Share extension) it crashes.

[PGLongo]

Please can you print the log and your code? Thanks

@ramunasjurgilas You cannot use PKHUD in an extension. The reason is that PKHUD tries to access UIApplication.shared which is forbidden in app extensions.

There is a fork by @Fab1n you can use: https://github.com/teamoutbank/PKHUD
In the fork the HUD is view-based instead of window-based. Just use the main view of the app extension as the base-view for the HUD.
Unfortunately it is not up to date with the version of @pkluz and it has not been ported to Swift 3 yet.

@pkluz Any chance that the view-based implementation by @Fab1n gets merged into the original PKHUD? https://github.com/teamoutbank/PKHUD/pull/1

@PGLongo Error happens because it uses UIApplication, but in share extensions it is not accessible/forbidden as @domhof wrote.

Error it self happens the 5th line.

internal class Window: UIWindow {
    internal let frameView: FrameView
    internal init(frameView: FrameView = FrameView()) {
        self.frameView = frameView
        super.init(frame: UIApplication.shared.delegate!.window!!.bounds) // 5th line
        commonInit()
    }
}

@domhof Thanks for comment.

@ramunasjurgilas If you want you can use my fork of PKHUD https://github.com/domhof/PKHUD. It is based on @pkluz s fork, but updated to 4.0.0 for Swift 3 support.

[PGLongo]

@domhof I've seen your fork. Any idea on how fix this problem without breaking the compatibility?

[ramunasjurgilas]

@domhof Thanks for the URL. I did look into commits and looks that this one is for Swift 3.0. Is it right?

[Fab1n]

Hey guys. Our fork is view based AND compatible with macOS. If you take the branch feature/ob-additions you will get all goodness AND Swift 3 support! As the name oft the branch tells you, we made all changes additional on top of the official pkhud master. So it should be very simple to merge

[Fab1n]

And we hope to get this into the official master. Would be an improvement

[pkluz]

+1 on getting them merged nicely.

@Fab1n it would be great if you could make a PR.

[Fab1n]

Here it is
#125

Hope this gets pulled in soon

[PGLongo]

I can make some test this Friday.

[PGLongo]

I've merge only 1 commit of that PR. Today I will check and merge others PR and then release a new pod version.

[PGLongo]

Released the new version. Try update your pod to 4.1.0 and then let me know.

Thanks

hi, I try to using 4.2.0 on my share extension podfile, and got the error like the attachment.

is this issue is already fix on the latest version ?

[Fab1n]

Sorry no, currently it is not possible to use that from an extension. You should propose a pullRequest or open a ticket for that. Maybe there is one already

[PGLongo]

I'm looking into it but it's very difficult for me at the moment to fix this.

If you have the time you could try the following:

1. Remove WindowRootViewController because it seems unused
2. Add an Other Swift Flags as follow

#if PKHUD_SHARED_EXTENSION
   guard null != view else {
    //throw Exception
 } 
#else
   let view: UIView = view ?? viewToPresentOn ?? UIApplication.shared.keyWindow!
#endif
