Mac下获取当前程序路径

1

NSString* getExePath()
{ 
    char buf[0] = {0}; 
    uint32_t size = 0;          
    _NSGetExecutablePath(buf,&size); 
    char* path = (char*)malloc(size+1); 
    path[size] = 0; 
    _NSGetExecutablePath(path,&size); 
    char* pCur = strrchr(path, '/'); 
    *pCur = 0; 
    NSString* nsPath = [NSString stringWithUTF8String:path];
    free(path);
    path = NULL;
    return nsPath;
}

执行命令脚本

void runSystemCommand(NSString *cmd)
{
    [[NSTask launchedTaskWithLaunchPath:@"/bin/sh"
                              arguments:@[@"-c", cmd]]
     waitUntilExit];
}
runSystemCommand(@"python /Users/1.py");
