从Objective C代码调用Python函数

Question

我正在尝试从下面的Objective c代码调用python类函数，这是我的目标c函数。

-(void) hitPython
{
    Py_Initialize();
    NSLog(@"PyInit");
    const char *pypath = [[[NSBundle mainBundle] resourcePath] UTF8String];

    // import sys
    PyObject *sys = PyImport_Import(PyString_FromString("sys"));

    // sys.path.append(resourcePath)
    PyObject *sys_path_append = PyObject_GetAttrString(PyObject_GetAttrString(sys, "path"), "append");
    PyObject *resourcePath = PyTuple_New(1);
    PyTuple_SetItem(resourcePath, 0, PyString_FromString(pypath));
    PyObject_CallObject(sys_path_append, resourcePath);

    // import MyModule   # this is in my project folder
    PyObject *myModule = PyImport_Import(PyString_FromString("MyModule"));

    // MyModule.my_func()
    PyObject *my_func = PyObject_GetAttrString(myModule, "my_func");

    if (my_func && PyCallable_Check(my_func)){
        PyObject *result = PyObject_CallObject(my_func, NULL);
        if(result != NULL){
            NSLog(@"Result of call: %s", PyString_AsString(result));
        }
    }
}

运行代码时出现以下错误。

我从系统库中添加了python框架，但仍然发生相同的错误。
