- 导入python.framework： https://github.com/pybee/Python-iOS-support/releases
- 设置homepath： Py_SetPythonHome(pythonHome);
#pragma mark - private
- (void)p_setupHomePath {
BOOL isEvn = [self configPythonEnvironment];
if (!isEvn) {
return;
}
const char * frameworkPath = [[NSString stringWithFormat:@"%@/Resources",[self p_pythonFrameworkPath]] UTF8String];
wchar_t *pythonHome = _Py_char2wchar(frameworkPath, NULL);
Py_SetPythonHome(pythonHome);
}
- (NSString*)p_pythonFrameworkPath{
NSString *documantPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES).lastObject;
NSString *newFrameworkPath = [documantPath stringByAppendingPathComponent:@"Python.framework"];
return newFrameworkPath;
}
-(BOOL)configPythonEnvironment
{
NSBundle *mainBundle = [NSBundle mainBundle];
NSString *bundlePath = [mainBundle pathForResource:@"PythonEnvironment" ofType:@"bundle"];
BOOL isExist = [[NSFileManager defaultManager] fileExistsAtPath:bundlePath];
if(!isExist) {
return NO;
}
NSBundle *bundle = [NSBundle bundleWithPath:bundlePath];
NSString *PythonPath = [bundle pathForResource:@"Python" ofType:@"framework"];
isExist = [[NSFileManager defaultManager] fileExistsAtPath:PythonPath];
if (!isExist) {
return NO;
}
NSString *newFrameworkPath = [self p_pythonFrameworkPath];
if ([[NSFileManager defaultManager] fileExistsAtPath:newFrameworkPath]) {
return YES;
}
NSError * error;
[[NSFileManager defaultManager] copyItemAtPath:PythonPath toPath:newFrameworkPath error:&error];
if (error) {
return NO;
}
return YES;;
}
注意这里的PythonEnvironment. bundle ，是对python.framework解压后，添加一些自己需要的第三方库
- 初始化，运行python代码：
Py_Initialize();
PyRun_SimpleString("print('hello world')");
- 运行py脚本
dispatch_queue_t queue = dispatch_queue_create(0, DISPATCH_QUEUE_CONCURRENT);
dispatch_async(queue, ^{
//run python scipt
NSString *scriptPath = [[NSBundle mainBundle] pathForResource:@"Test" ofType:@"py"];
FILE *mainFile = fopen([scriptPath UTF8String], "r");
PyRun_SimpleFile(mainFile, (char *)[[scriptPath lastPathComponent] UTF8String]) ;
});
- 释放解释器
Py_Finalize();
最后的代码：
#import "PythonRunner.h"
#import <Python/Python.h>
@implementation PythonRunner
+(Boolean)run{
BOOL isEvn = [self configPythonEnvironment];
if(!isEvn){
return false;
}
[PythonRunner p_setupHomePath];
Py_Initialize();
//run simple python code
PyRun_SimpleString("print ('hello')");//say hello see debug output :)
dispatch_queue_t queue = dispatch_queue_create(0, DISPATCH_QUEUE_CONCURRENT);
dispatch_async(queue, ^{
//run python scipt
NSString *scriptPath = [[NSBundle mainBundle] pathForResource:@"Test" ofType:@"py"];
FILE *mainFile = fopen([scriptPath UTF8String], "r");
PyRun_SimpleFile(mainFile, (char *)[[scriptPath lastPathComponent] UTF8String]) ;
});
return true;
}
