run a simple python script in ios
提问by Matt3o12
I want to run a python script on ios. I don't want to write the whole Application in Python just a little part of it.
我想在 ios 上运行一个 python 脚本。我不想用 Python 编写整个应用程序，只是其中的一小部分。
I have tried to understand PyObjC but it is not that easy.
我试图理解 PyObjC，但这并不容易。
Could you give me an example, please? I would like to save the result for the following method in a NSStringvariable.
请你给我举个例子好吗？我想将以下方法的结果保存在一个NSString变量中。
def doSomething():
someInfos = "test"
return someInfos

Here is an example of calling a function defined in myModule. The equivient python would be:
下面是一个调用 中定义的函数的例子myModule。等效的蟒蛇将是：
import myModule
pValue = myModule.doSomething()
print pValue
In Objective-c:
在 Objective-c 中：
#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);
}
