I have created a modified version of dropboxlogin.py that generates short-lived access tokens. So far, it seems to work with dropbox version 6.4.0 that is provided with Pythonista.

First run will authorize your application and store a long-lived refresh token in your device keychain.

# simple test app
import dropboxlogin
dropbox_client = dropboxlogin.get_client()
print('Getting account info...')
account_info = dropbox_client.users_get_current_account()
print('linked account:', account_info)

I was able to update dropbox to the latest version with this work around script which downloads the dropbox wheel and unzips the contents in site-packages. I had to use Stash pip to install the requests, six and stone. I'm still testing to see if it is better to stick with the original Pythonista dropbox version or to use the upgraded versions of dropbox, requests and six.

# workaround to install latest dropbox in pythonista
# install requirements using stash pip
# pip install requests
# pip install six
# pip install stone

import sys, os
import requests
from zipfile import ZipFile

sitepath = os.path.expanduser('~/Documents/site-packages-3')
os.chdir(sitepath)
from zipfile import ZipFile
url = 'https://files.pythonhosted.org/packages/ef/64'
url += '/2ef3c03ac039f9e5f29c0f557dc3f276241ef3c1627903a5f6a8c289cf24/'
url += 'dropbox-11.7.0-py3-none-any.whl'
dest_path = './dropbox.zip'
r = requests.get(url)

with open(dest_path, 'wb') as f:
    f.write(r.content)
    print('download complete...')

with ZipFile(dest_path, 'r') as zip:
    # extracting all the files
    print('Extracting all the files now...')
    zip.extractall()
    print('Done!')

os.remove(dest_path)

I installed dropbox version 11.7.0 a year ago and I appears to still be working today.

This code works on my iPhone 12.

I added @ui.in_background to def select_author(sender)

I will also test the Lock code.

import ui
#
def show_list_dialog(items=None, *args, **kwargs):
    items = items or []
    tbl = ui.TableView(**kwargs)
    tbl.data_source = ui.ListDataSource(items)
    my_sel = {'value': None}
    class MyTableViewDelegate (object):
        def tableview_did_select(self, tableview, section, row):
            print('items:', tableview.data_source.items)
            print('section, row:', section, row)
            my_sel['value'] = tableview.data_source.items[row]
            tableview.close()
            print('in delegate: my_sel',my_sel['value'])
    tbl.delegate = MyTableViewDelegate()
    tbl.present(style='sheet')
    tbl.wait_modal()
    print('after wait: ', my_sel['value'])
    return my_sel['value']
#

    selected_author = show_list_dialog(author_unique, frame=f, name='Select an Author')
    print('list dialog returned:', selected_author)
    global author_result
    author_result.text = str(selected_author)
    return

@

@felciano There appear to be 2 issues.

• Dropbox version 11.7.0 crashes when using the appex module.
• The keychain module does not work with the appex module.

You will need to use Dropbox 6.4.0 and you will need to store your refresh_token somewhere else besides keychain.

You can modify dropboxlogin like this:

#refresh_token = keychain.get_password('dropbox', 'refresh_token')
refresh_token = "your_refresh_token"

You can then remove the dropbox folders from site-packages-3 or try this script which removes site-packages-3 from sys.path when running from a share sheet and temporarily reverts back to dropbox 6.4.0.

import sys
import appex
import console

print('file', appex.get_file_path())

def test():
    print(sys.path[1])
    if appex.is_running_extension():  # if share sheet  
        sys.path.remove(sys.path[1])  # remove site-packages-3 from sys.path  
    import dropbox
    print('dropbox version', str(dropbox.__version__))

    import dropboxlogin
    dropbox_client = dropboxlogin.get_client()
    print('Getting account info...')
    account_info = dropbox_client.users_get_current_account()
    print('linked account:', account_info)
    
test()
    

If you are just trying to upload a file from a share sheet, this script does not use the dropbox module:

import sys, os, json, shutil
import appex
import console
import keychain
import requests
from requests.auth import HTTPBasicAuth

app_key = "your_app_key"
app_secret = "your_app_secret"
refresh_token = "your_refresh_token"

def dropbox_token(refresh_token):
    data = {'refresh_token': refresh_token, 'grant_type': 'refresh_token'}
    try:
        r = requests.post('https://api.dropbox.com/oauth2/token', data=data,
            auth = HTTPBasicAuth(app_key, app_secret))
        result = r.json()
    except:
        print(str(sys.exc_info()))
        return { 'refresh_token': None, 'access_token': None, 'error': {'.tag': str(sys.exc_info())} }

    #print('dbx:', result)
    return result
    
def upload_file(source_filename, path):
    with open(source_filename, 'rb') as f:
        data = f.read()

    parms = {}
    parms['path'] =  path
    parms['mode'] =  'overwrite'
    print (json.dumps(parms))
    headers = {'Authorization': 'Bearer %s' % (access_token,),'Dropbox-API-Arg': json.dumps(parms),'Content-Type': 'application/octet-stream' }
    url = 'https://content.dropboxapi.com/2/files/upload'
    try:
        r = requests.post(url, stream=True, headers=headers, data=data)
    except:
        print("Exception requests: %s" % str(sys.exc_info()))
    result = r.json()
    return result
    
local_path = os.path.expanduser('~/Documents/tmp')
access_token = dropbox_token(refresh_token)['access_token']

files = appex.get_file_paths()
if files != None and files != []:
    for i in range(len(files)):
        print('Input path: %s' % files[i])
        basename = os.path.basename(files[i])
        filename=os.path.join(local_path, basename)
        shutil.copy(files[i], filename)
        upload_file(basename, '/remote/dropbox/path/' + basename)

@ccc This link is for Microsoft OneDrive. My Dropbox space is limited.

The original link is a more permanent and reliable alias to this URL.

https://onedrive.live.com/?authkey=!AC94lHutmY315L4&id=98B88F62EF7BB2B3!125&cid=98B88F62EF7BB2B3

Ok. Now I see how to include source.

import requests
import urllib
import os
import ui
import json

def list_folder(folder_path='/'):
    headers = {'Authorization': 'Bearer %s' % (TOKEN,),'Content-Type': 'application/json' }
    if folder_path == '/': folder_path = ''
    data = {'path':folder_path}
    r = requests.post('https://api.dropboxapi.com/2/files/list_folder', headers=headers, data=json.dumps(data))
    result = r.json()
    return result.get('entries', None)

def download_file(path, dest_filename, progress=None):
    data = {'path':path}
    headers = {'Authorization': 'Bearer %s' % (TOKEN,),'Dropbox-API-Arg': json.dumps(data)}
    url = 'https://content.dropboxapi.com/2/files/download'
    r = requests.post(url, stream=True, headers=headers)

You also need to replace 'path' with 'path_dislpay' in twice in def load_folder.

@ui.in_background
    def load_folder(self):
        infos = list_folder(self.path)
        items = []
        if self.path != '/':
            items.append({'title': '..', 'image': 'ionicons-arrow-up-c-32', 'up': True})
        if not infos:
            import console
            console.alert('Error', 'Could not load folder. Please check if you entered the access token correctly.', 'OK', hide_cancel_button=True)
            self.status_label.hidden = True
            return
        for info in infos:
            path = info.get('path_display')
            name = os.path.split(path)[1]
            if name.startswith('.'):
                continue
            is_dir = info.get('is_dir', False)
            item = {'title': name, 'image': 'ionicons-folder-32' if is_dir else 'ionicons-ios7-download-outline-32', 'accessory_type': 'disclosure_indicator' if is_dir else 'none', 'is_dir': is_dir, 'path': info['path_display']}

Is there a new build number? Using this link https://testflight.apple.com/v1/app/1085978097?build=102223475, I get an error message "This build is not longer available"

@vkcatfish This works on an iPad if your ok with just hiding the minutes. It would require some adjustments on an iPhone.

import ui
from datetime import datetime

def date_changed(sender):
    print(sender.date)
    print(sender.date.strftime("%Y-%m-%d %H:%M"))
    print(sender.date.strftime("%Y-%m-%d %I %p"))

v = ui.DatePicker()
v.name = 'Date Picker'
v.frame = (0,0,400,200)
v.background_color = 'lightgray'
v.mode = ui.DATE_PICKER_MODE_DATE_AND_TIME
v.action = date_changed
#v.date = datetime.strptime('2022-11-30 14:11', "%Y-%m-%d %H:%M")
dtm = datetime.now()
v.date = datetime(dtm.year, dtm.month, dtm.day, dtm.hour)
hi = ui.View()
x = 250

@gojyuan Have you tried using the @ui.in_background decorator?

@ui.in_background
def button_tapped(sender):
    items = ['A', 'B', 'C', 'D']
    result = list_dialog(title='Select item', items=items)
    print('list dialog returned:', result)

I installed dropbox version 11.7.0 a year ago and I appears to still be working today.

@cvp No problem. I thought maybe your question was intended for @mikeno.

@cvp I bought Pyto in 2019. I am currently running Pyto 17.1.1 I have tested barometer.py on iPhone 12 mini and iPad mini 4th gen.

@cvp Correct. After my morning brain fog cleared, that is what you said in your last edit. :-)

I dropped the 2nd parameter (error) because it caused an exception: "item 2 in argtypes has no from_param method", so I tried running without the error parameter.

After reading the last comment by @JonB I now understand the proper use of @Block witch can be called directly.

This works for me.

    nspressure = ObjCInstance(_data).pressure
    global pressure
    pressure = py_from_ns(nspressure)

"""

def get_pressure():
    CMAltimeter = ObjCClass('CMAltimeter')
    NSOperationQueue = ObjCClass('NSOperationQueue')
    if not CMAltimeter.isRelativeAltitudeAvailable():
        print('This device has no barometer.')
        return
    altimeter = CMAltimeter.new()
    main_q = NSOperationQueue.mainQueue
    #altimeter.startRelativeAltitudeUpdatesToQueue_withHandler_(main_q, handler_block)
    altimeter.startRelativeAltitudeUpdatesToQueue_withHandler_(main_q, handler)
    print('Started altitude updates.')
    try:
        while pressure is None:
            pass
    finally:
        altimeter.stopRelativeAltitudeUpdates()
        print('Updates stopped.')
        return pressure

if __name__ == '__main__':
    result = get_pressure()
    print(result)
    del pressure

@mikeno This code works for me with the latest version of pyto.
