Hi again,

I changed Jon's NSLog function to make it a little bit more efficient:

from objc_util import c, ns, c_void_p, c_void_p

_nslog = c.NSLog
_nslog.argtypes = [c_void_p, c_void_p]
_nslog.restype = None

def NSLog(msg):
    _nslog(ns('%@'), ns(str(msg)))

I think it would be nice if it could be added to the objc_util package directly, as it has been very useful to me.
Notice I cast the msg parameter into a string, that way you can pass anything you want to it and it will output that to the XCode console.

Cheers
Andre

Hello everyone,

Here is a reworked script that adds the comments at the top but preservers coding= comments.
It is not perfect, but it helped me succesfully submit an app to the Appstore, I hope it is of help to every one.

Hello everybody,

I found what was not working with the creation of my TableView using the PythonistaAppTemplate

When you use the following syntax it doesn't work:

tbl = ui.TableView(frame=(0, 0, 400, 600))

You have to do it in two lines and then it works, like so:

tbl = ui.TableView()
tbl.frame = (0, 0, 400, 600)

I hope this can be useful, it took me a long time to find out what was wrong.

Cheers
Andre

Thanks @mikashkin, I didn't think to look for them there :)
Andre

Thanks @ccc! now I can get those into PyCharm :-)
Andre

Hi Jon,

I think that is a very good question and a very interesting option to explore as it would avoid modifying the framework. I'll look into it as soon as I get a chance and report my findings back.

Cheers
Andre

Thank you so much Jon, that worked like a charm! Now I can debug within XCode.
I'm having difficulties with Custom ListViews that I hope to solve, they work fine within Pythonista but once they are on the simulator not anymore or the phone :(

Cheers
Andre

Hi everybody,

I am trying to debug a Pythonista script which I'm using with the PythonistaAppTemplate in XCode. I would like to use NSLog to output messages to the XCode console but I don't know how to access it. Can anybody help ?
Thanks in advance

Hi Mark,

Synchronator seems great, unfortunately I keep getting this error when I run it on Pythonista 3 using Python 3.5.
I used StaSh pip install to install the latest dropbox and requests to no avail, here is the stack trace, it seems to be a timeout problem :(

HI @JonB,

I'll look into the AudioEngine, but for now I am using sound.Player() with some success.. I'm trying to determine what is the smallest wav file I can generate that will loop correctly, it's a lot of trial and error.

Cheers
Andre

Thanks @ccc,

I had seen those examples, but what I need to do is produce sound, I managed some, the problem is as soon as I leave pythonista in the background the sound stops :(

Cheers
Andre

Hello everyone,

I'd like to write an app to do tone generation in real time and I know the way to do it without glitches would be through CoreAudio. After going trough some of the very old posts discussing it, it is not clear to me wether this could be possible with Pythonista 3.0. Any ideas ?
Thanks in advance

Cheers
Andre
