I am trying to open from my keyboard extension. I am having custom keyboard and I have add that keyboard from setting. On my custom keyboard there is one button “Show More”, and I want to open my app on this button click.
So I have tried following code :
let context = NSExtensionContext()
context.open(url! as URL, completionHandler: nil)
var responder = self as UIResponder?
while (responder != nil) {
if responder?.responds(to: Selector("openURL:")) == true {
responder?.perform(Selector("openURL:"), with: url)
}
responder = responder!.next
}It is working successfully, but as we know in swift
Selector("method_name:")#selector(classname.methodname(_:))if responder?.responds(to: #selector(UIApplication.openURL(_:))) == true {
responder?.perform(#selector(UIApplication.openURL(_:)), with: url)
}Also tried :
if responder?.responds(to: #selector(NSExtensionContext.open(_:))) == true {
responder?.perform(#selector(NSExtensionContext.open(_:)), with: url)
}I have also tried others possible ways, but no luck. If anyone know how to do, please let me know.
I referred this link, Julio Bailon’s answer : openURL not work in Action Extension
I want to be very clear: what you’re doing here is very much unsupported. Two points:
The
on NSExtensionContext is specifically documented for use on Today widgets only.open(_:completionHandler:)Trying to get around this by walking up the responder chain looking for and calling methods by their selector is not allowed.
While I realise that Apple can be rather opaque at times, the intent here is very clear: if we wanted
open(_:completionHandler:)If you’d like your keyboard extension to be able to open your app, you should file an enhancement request for a supported way to do that. Personally, I think that’s a reasonable request, but I don’t get to make the call.
Please post your bug number, just for the record.
Share and Enjoy
