Python for ios解释器

本文介绍了Python for ios解释器的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

可能重复： iOS上的Python或Ruby解释器

我只是发现这个应用程序 pypad 和 python for ios

I just discovered this apps pypad and python for ios

他们喜欢翻译编辑

那么你会推荐哪个app

So which app would you recomend

但最重要的是，这个解释器是如何工作的，我在哪里可以看到一个如何使用obj c的例子和python开始工作togheter？

But most importantly, how does this interpreter work, and where can i see an example of how the obj c and python get to work togheter?

谢谢！

推荐答案

我我是适用于iOS的Python 的唯一创建者，所以这当然是我推荐的，但是个人决定的一个很好的指标是评论&安培;每个应用程序的评级。我花了几周的时间才弄清楚如何将python正确地集成到这个App的Objective-c中，但这里是让你入门的最佳资源（请记住，ObjC只是C的超集）：

I am the sole creator of Python for iOS so that is of course what I would recommend, but a good indicator for your personal decision is the reviews & ratings of each App. It took me weeks to figure out how to properly integrate python into Objective-c for this App but here is the best resource to get you started (keep in mind that ObjC is just a superset of C):

docs.python/c-api/

此外，这是一个调用 myModule 。等价的python将是：

Also, here is an example of calling a function defined in myModule. The equivient python would be:

import myModule pValue = myModule.doSomething() print pValue

在Objective-c中：

In Objective-c:

#include <Python.h> - (void)example { PyObject *pName, *pModule, *pDict, *pFunc, *pArgs, *pValue; NSString *nsString; // Initialize the Python Interpreter Py_Initialize(); // Build the name object pName = PyString_FromString("myModule"); // Load the module object pModule = PyImport_Import(pName); // pDict is a borrowed reference pDict = PyModule_GetDict(pModule); // pFunc is also a borrowed reference pFunc = PyDict_GetItemString(pDict, "doSomething"); if (PyCallable_Check(pFunc)) { pValue = PyObject_CallObject(pFunc, NULL); if (pValue != NULL) { if (PyObject_IsInstance(pValue, (PyObject *)&PyUnicode_Type)) { nsString = [NSString stringWithCharacters:((PyUnicodeObject *)pValue)->str length:((PyUnicodeObject *) pValue)->length]; } else if (PyObject_IsInstance(pValue, (PyObject *)&PyBytes_Type)) { nsString = [NSString stringWithUTF8String:((PyBytesObject *)pValue)->ob_sval]; } else { /* Handle a return value that is neither a PyUnicode_Type nor a PyBytes_Type */ } Py_XDECREF(pValue); } else { PyErr_Print(); } } else { PyErr_Print(); } // Clean up Py_XDECREF(pModule); Py_XDECREF(pName); // Finish the Python Interpreter Py_Finalize(); NSLog(@"%@", nsString); }
