I have noticed a possible bug in the UI editor of Pythonista. The issue is choosing an image for a button using the button's attribute image select option in the UI editor.
As I was designing a UI with the editor, I would try out different button images for a single button to see how they looked. I was trying to pick the best icon for the job. While going back and forth between running the app and and changing the icon, I noticed the icon stop changing and responding to selections in the buttons attributes. I could choose a new icon but the image change would not reflect after changing the icon 8 or 9 times. I also deleted the button and tried making a new button but the issue seemed globally within the app.
Things I tried was restarting the app(deleting from multitasking), rebooting the phone, and trying a new script.The new script removed the issue but had the same problem eventually. This is not a big deal but wanted to make sure I voiced it.
This is probably a bug. Were you changing this in the UI editor, or in the script? If the UI editor, try changing it in your program.
It happened in the editor. I will try it in the program. I noticed that it happens when the button title is blank only.
