如何以编程方式创建ICNS图标？

问题描述

OK这是我想要的：

• 取一些 NSImage s


• 将它们添加到 ICNS 文件


• 保存

这是我到目前为止做的（纯粹作为测试）：

   - （CGImageRef）refFromImage：（NSImage *）img 
 {
 CGImageSourceRef source; 
 
 source = CGImageSourceCreateWithData（（CFDataRef）[img TIFFRepresentation]，NULL）; 
 CGImageRef maskRef = CGImageSourceCreateImageAtIndex（source，0，NULL）; 
 
 return maskRef; 
} 
 
  - （void）awakeFromNib 
 {
 NSImage * img1 = [NSImage imageNamed：@image1]; 
 NSImage * img2 = [NSImage imageNamed：@image2]; 
 
 NSLog（@％@，img1）; 
 CGImageRef i1 = [self refFromImage：img1]; 
 CGImageRef i2 = [self refFromImage：img2]; 
 
 NSURL * fileURL = [NSURL fileURLWithPath：[@〜/ Documents / final.icnsstringByExpandingTildeInPath]]; 
 CGImageDestinationRef dr = CGImageDestinationCreateWithURL（（__ bridge CFURLRef）fileURL，kUTTypeAppleICNS，1，NULL）; 
 
 CGImageDestinationAddImage（dr，i1，NULL）; 
 CGImageDestinationAddImage（dr，i2，NULL）; 
 / *甚至尝试添加'multiple'次
 
 CGImageDestinationAddImage（dr，i1，NULL）; 
 CGImageDestinationAddImage（dr，i2，NULL）; 
 CGImageDestinationAddImage（dr，i1，NULL）; 
 CGImageDestinationAddImage（dr，i2，NULL）; 
 
 * / 
 
 CGImageDestinationFinalize（dr）; 
 
 CFRelease（dr）; 
} 
  

但是，它仍然会发生错误：

我的代码有什么问题？

我已经看过下面的答案， / p>

解决方案

您可以使用。

  NSImage * mImage = [NSImage alloc] initWithContentsOfFile：@/ Users / Username / Desktop / WhiteTiger.jpg]; 
 IconFamily * fam = [IconFamily iconFamilyWithThumbnailsOfImage：mImage]; 
 [fam writeToFile：@/ Users / Username / Desktop / WhiteTiger.icns]; 
  

OK this is what I want :

• Take some NSImages
• Add them to an ICNS file
• Save it

This is what I've done so far (purely as a test) :

- (CGImageRef)refFromImage:(NSImage*)img
{
    CGImageSourceRef source;

    source = CGImageSourceCreateWithData((CFDataRef)[img TIFFRepresentation], NULL);
    CGImageRef maskRef =  CGImageSourceCreateImageAtIndex(source, 0, NULL);

    return maskRef;
}

- (void)awakeFromNib
{
    NSImage* img1 = [NSImage imageNamed:@"image1"];
    NSImage* img2 = [NSImage imageNamed:@"image2"];

    NSLog(@"%@",img1);
    CGImageRef i1 = [self refFromImage:img1];
    CGImageRef i2 = [self refFromImage:img2];

    NSURL *fileURL = [NSURL fileURLWithPath:[@"~/Documents/final.icns" stringByExpandingTildeInPath]];
    CGImageDestinationRef dr = CGImageDestinationCreateWithURL((__bridge CFURLRef)fileURL, kUTTypeAppleICNS , 1, NULL);

    CGImageDestinationAddImage(dr, i1, NULL);
    CGImageDestinationAddImage(dr, i2, NULL);
    /* Even tried adding 'multiple' times

    CGImageDestinationAddImage(dr, i1, NULL);
    CGImageDestinationAddImage(dr, i2, NULL);
    CGImageDestinationAddImage(dr, i1, NULL);
    CGImageDestinationAddImage(dr, i2, NULL);

    */

    CGImageDestinationFinalize(dr);

    CFRelease(dr);
}

But, it still keeps throwing an error :

What's wrong with my code?

I've had a look at the answers below, but still nothing :

• Save CGImageRef to PNG file errors? (ARC Caused?)
• How exactly to make a CGImageRef from an image on disk

解决方案

You can use IconFamily.

NSImage *mImage = [[NSImage alloc] initWithContentsOfFile:@"/Users/Username/Desktop/WhiteTiger.jpg"];
IconFamily *fam = [IconFamily iconFamilyWithThumbnailsOfImage:mImage];
[fam writeToFile:@"/Users/Username/Desktop/WhiteTiger.icns"];
