Load Image from URL
-
I am making a dumb little program to learn how to use Pythonista. I am trying to something that changes the text/image when you tap the forward or back buttons. I cannot get the image to view. Does anybody see what I am doing wrong? Thanks.
import ui page_count = 1 # text for each page page1_text = 'This app introduces the game of baseball.\nUse the navigtion arrows to change pages.' page2_text = 'Page 2' page3_text = 'Page 3' # images for each page page1_img = 'http://www.talmageboston.com/files/2016/04/Baseball-Grass.jpg' def update_page(page_text, page_img): if page_count == 1: page_text.text = page1_text page_img.load_from_url(page1_img) v = ui.load_view() page_text = v['textview1'] page_img = v['imageview1'] v.present('sheet') while True: update_page(page_text, page_img)

You're right for the default name.
I've tried without the "while true" and the picture is displayedThe load_view is asynchronous and you infinite loop doesn't let enough time for loading the URL.
Why do you put this while loop?
-
Not sure. I commented out the line, but it still does not load for me.

Strange, for me, it's ok
Did you move the next line left?

Does the textview object not hide the imageview object?

Here is the UI file looks like:
The imageview is above the textview.Here is what my output looks like:

I just got the same problem, picture does not appear any more.
Remove Pythonista app from tasks list (4/5 fingers up, slide app up) and restart Pythonista

It works, thanks. Do you know why I needed to restart the app?

No, sorry but @omz is watching you 😅
You'll receive an explanation.
Perhaps, the site where you get your picture does not respond immediately if you make too much requests from an app, I have had this kind of problems on Google site.In reality, when your picture is not displayed, the script seems locked because even the close button does not response.
