Close app from home screen button
-
Hi, i open with a script an ui-View with Nav-Controller. In the Nav-Controller there is an Exit Button. This button should close the app (script running in Pythonista). Temporaly it only close the script and not the Pythonista app.
-
@kami in iOS, we never can close an app... It is still in memory until you manually remove it.
-
ok, i think we have a terminology problem...
you wrote a script, which you are calling an app. we thought you meant the app called Pythonista.
can you share your script, or a scaled down example?
I suspect part of your problem is that there is an issue whereby when you run a script from the home screen, it runs the script twice. so, when you close your view, there is another copy just behind it....someone had a workaround for that... see TPO's workarounds here:
https://forum.omz-software.com/topic/5440/prevent-duplicate-launch-from-shortcut/7basically, until this bug is fixed, you need to check if your script is already running before launching it. i think there is another approach where you search through the gc.garbage for ui.View's that are on_screen, and close those .

Hi,
you are right. I wrote a script. And it opens twice. I now implemented the AppSingleLaunch module. In Pythonista directly everything runs fine. But if i add a Homebutton the Mainview opens but if i try to switch with the navigationview to another view the script always tells that nav view and the loaded view is not defined.
Can you help me?

@kami, just a reminder that you can avoid the double launch by opening the script with Apple Shortcuts, and you can place the shortcut on the home screen.
-
For the not defined variables, the issue is that globals are being cleared. @shinyformica recently resolved a similar issue .
https://forum.omz-software.com/topic/5440/prevent-duplicate-launch-from-shortcut/12
You have to implement the don't-clear-globals bit in pythonista_startup.

Hi,
thanks a lot. This works fine and now there is no missing nav or v element. There are also no double views. But there is still the Problem, that when i run the script from the home shortcut button and close it. Pythonista is still active in the background and i can not restart the app from the home shortcut but. I have to close manually pythonista from the ios screen and then i can restart the script.
This is no my problem.
Thanks a lot.

@kami, not sure which of the options discussed in this thread you ended up using, but I launch the script from a Apple Shortcuts shortcut on the home screen. The shortcut uses a ”pythonista3” URL, and I can launch it repeatedly without restarting Pythonista.
-
@mikael I think it depends of what your script does. I have a script that displays a MKMapView with 1200 customized pin's and I need to remove Pythonista at each run.
-
-
@cvp, do I understand correctly that the need to relaunch Pythonista depends on how your script is launched?
-
I suspect that the script is the impressive https://github.com/cvpe/Pythonista-scripts/blob/master/contacts on map.py and that memory is being allocated but not being released.
-
-
@ccc No, no. The script showing my contacts on a map is not a big script and I don't have 1200 contacts (happily). It is a very big script (at least for me) of 7500 lines written for a friend who is "radio amateur" and showing the 1200 contacts he has realized with other people in the world. Each pin has an associated DetailCalloutAccessoryView with address, flag and other informations.
And, seeing the two rows of menu buttons, you can imagine that the program offers a lot of functionalities -
@cvp, oh my goodness, that looks cool!

Hi,
thanks a lot for all the answer. But this doesn't solve my problem. So for now i made a simple example for everyone which will show my problem. I created a python script like this:
import ui import os def close(sender): v.close() os.abort() v = ui.load_view() v.present('sheet')
and a pyui:
[ { "nodes" : [ { "nodes" : [ ], "frame" : "{{95, 162}, {80, 55}}", "class" : "Button", "attributes" : { "action" : "close", "frame" : "{{95, 217}, {80, 32}}", "title" : "Button", "uuid" : "B05F9F96-41D2-41C1-B4E1-C27F68D5CD4A", "class" : "Button", "name" : "button1", "font_size" : 15 }, "selected" : true } ], "frame" : "{{0, 0}, {270, 466}}", "class" : "View", "attributes" : { "enabled" : true, "background_color" : "RGBA(1.000000,1.000000,1.000000,1.000000)", "tint_color" : "RGBA(0.000000,0.478000,1.000000,1.000000)", "border_color" : "RGBA(0.000000,0.000000,0.000000,1.000000)", "flex" : "" }, "selected" : false } ]
With this script and UI i just add a Button on the Home screen like it is described in Pythonista.
Then i close all app on my iphone. I press the button and the App is opening twice. I press the Button in the UI and it closes. I see the normal Iphone homescren. If i now press the Home screen Button of the App (the shortcut), i only see a screen from Pythonista with a complete green background. I have to close manually from the IOS all pythonista screen and after this i can normally start the shortcut of the script again. So how can help me with this.
Thanks a lot.

@kami, just to rule out potential issues, can you confirm that you tried launching your script via a home screen icon that you created with the Apple Shortcuts app?
I used this simple script, called test-launch.py:
import ui, os class SuperClose(ui.View): def will_close(self): os.abort() v = SuperClose(background_color='red') v.present()
And this URL in the Shorcuts app:
pythonista3://test-launch?action=run
And the script is launched only once and Pythonista goes away when I close the view.
