Python/Kivy环境在IOS上写入iCloud文档的数据

使用Python/Kivy为iOS/iPhone环境。

应用程序本身运行良好，Python/Kivy->toolchain.py->XCode->iPhone操作。

我希望通过iCloud为多个平台共享应用程序数据，因此希望将数据写入iCloud文档存储。我可以做好使用iCloud的所有准备(绑定标识符、AppID、供应配置文件，并成功地激活了XCode上的iCloud和iCloud文档)。然后，我在互联网上没有找到示例代码，也没有找到如何使用Python/Kivy将数据写入iCloud文档存储或将数据从存储复制到iCloud文档存储的书籍。也许，如果我可以使用Python/Kivy使函数等价于以下SWIFT代码，我就能够解决这个问题。

<Swift code>
let manager = NSFileManager()
let manager.copyItemAtPath(srcPath, toPath: toPath, error: nil)

有没有办法使用Python/Kivy将数据写入iCloud或将数据从用户存储复制到iCloud存储？下面是一个示例代码，我想添加这样的函数。

<Python>
from kivy.app import App
import os
import pickle

setting_in = {'parameter1': 'abcde', 'parameter2': 'fghij'}
setting_out = {}
def readsetting(read_settingfilename):
    setting1 = {}
    if os.path.exists(read_settingfilename):
        try:   
            with open(read_settingfilename, 'rb') as f1:                 
                try:           
                    setting1 = pickle.load(f1)                         
                except pickle.UnpicklingError:        
                    print('Read error!')         
                else:
                    print('********** File' + read_settingfilename + 'was read!! **********')    
        except IOError:  
            print('File' + read_settingfilename + 'could not be opened for reading')          
        else:
            pass

    return setting1

def writesetting(write_settingfilename, setting1):
    try: 
        with open(write_settingfilename, 'wb') as f: 
            try:
                pickle.dump(setting1,f) 
            except pickle.PicklingError:
                print('File output error!') 
                outputflag = 1
            else:
                print('********** File created!! **********')    
                outputflag = 0
    except IOError:
        print('File' + write_settingfilename + 'could not be opened for writing') 
        outputflag = 1
    return outputflag

DATAPATH = App().user_data_dir + 'test/'
if os.path.isdir(DATAPATH) == False:
    os.mkdir(DATAPATH)

datafilename = 'test.dat' 
writesetting(DATAPATH + datafilename, setting_in)
setting_out = readsetting(DATAPATH + datafilename)
print(setting_out)
