Pythonista hangs on opening Photo Library

Hi,

i am using Pytonista on an Iphone 15 Pro (iOS 17.2.1) and Pythonista 3.4.

On a older Iphone XS (iOS 17.2.1) everything works fine. But on the new Iphone if i just press the Button form the UI. The Iphone App hangs a lot.

I i just run the "photos.pick_asset". It works fine. Could it be a problem with the Popup Function?

In the UI Script there is just a button which start the launchimg() function.

BR kami

import ui import photos

def launchimg(sender): assets = photos.pick_asset(assets=photos.get_assets(media_type='image'),title='Select Image2', multi=True) print (assets)

assets = photos.pick_asset(assets=photos.get_assets(media_type='image'),title='Select Image1', multi=True) print (assets)

v= ui.load_view('image') v.present()

How long does assets=photos.get_assets(media_type='image') take to run?

30sec - 60secs and more. But it is also the same problem if i run "assets = photos.capture_image()"

Does the following work if you leave out all of the ui code?

import photos

def launch_img(sender):
    print("Calling photos.get_assets(media_type='image')...")
    assets = photos.get_assets(media_type='image')
    print(f"{len(assets)} images found. -- Calling photos.pick_asset()")
    assets = photos.pick_asset(assets, title='Select images', multi=True)
    print(f"{len(assets)} images selected.")

if __name__ == "__main__":
    launch_img(None)

If not, does multi=False change things?

Hi, works fine with both True and False. The hanging just starts if i use a Button.

Cool... So first get the images from the user and then once that is finished you can do the ui work.

import photos
import ui

def launch_img(sender):
    print("Calling photos.get_assets(media_type='image')...")
    assets = photos.get_assets(media_type='image')
    print(f"{len(assets)} images found. -- Calling photos.pick_asset()")
    assets = photos.pick_asset(assets, title='Select images', multi=True)
    print(f"{len(assets)} images selected.")
    return assets

if __name__ == "__main__":
    assets = launch_img(None)
    if assets:
        view = ui.load_view('image')
        view.present()

No, sorry that is just a small example for the problem. The main app is much bigger and in this app i need to use a button. So the problem should be somewhere else. Because on my older iphone it is no Problem.

You probably need the @ui.in_background function decorator somewhere in your code as discussed at:

Hi, if i put @ui.in_background before every function it works fine. But why do i need this now and not in the past? Can i fix it any way else. Maybe globally?
