在 Objective-C 中调用 C 函数从 Nib 唤醒

我必须在 Objective-C 类中实现一个 C 函数，该函数通常会被调用int main（在它自己的文件中）。由于我不熟悉拼接代码，我需要知道如何在awakefromnib or applicationDidFinishLaunching来自可可部分。或者如果有更好的方法可以做到这一点，我正在倾听。

这是一个没有太技术性的示例：

// Cocoa Imports

#import "AppDelegate.h"
...

// C Inlcudes
#include <stdio.h> 

// (int main had to change to something else obviously)

int dos () { 
printf ("I'm a C program\n"); 
}

// (back to cocoa)

@implementation AppDelegate

@synthesize window;

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{

//[This is where I need my C function above to execute]

它的调用方式与 C 中的调用方式相同，您可以调用任何您喜欢的 C 函数：

// Cocoa Imports

#import "AppDelegate.h"
...

// C Inlcudes
#include <stdio.h> 

// (int main had to change to something else obviously)

int dos (const char *filename)
{ 
    printf ("I was passed '%s'\n", filename); 
}

// (back to cocoa)

@implementation AppDelegate

@synthesize window;

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
    dos("/path/to/some/file");
}
