如何徽章文件和文件夹使用可可 [英] How to badge file and folder using cocoa

问题描述

我想用一些颜色（图像）徽章文件和文件夹，任何想法如何可以实现
我试图与图标服务，它工作的文件，但它不工作的文件夹。

我看到此行为正常工作 Dropbox （10.4，10.5和10.6 ） - 任何想法如何可以做到这一点？

以下是非常接近一个为我，但它不能正常工作。

除了图标服务之外还有其他解决方案吗？ p>

我很感激任何帮助。

解决方案

以下函数是我为问题找到的解决方案

  BOOL AddBadgeToItem（NSString * path，NSData * tag）
 
 {
 FSCatalogInfo info; 
 FSRef par; 
 FSRef ref; 
 Boolean dir = false; 
 
 if（tag&（FSPathMakeRef（[path fileSystemRepresentation]，& par，& dir）== noErr））
 {
 HFSUniStr255 fork = {0， {0}}; 
 sint16 refnum = kResFileNotOpened; 
 FSGetResourceForkName（& fork）; 
 
 if（dir）
 {
 
 NSString * name = @Icon\r; 
 memset（& info，0，sizeof（info））; 
（（FileInfo *）（& info.finderInfo）） - > finderFlags = kIsInvisible; 
 
 OSErr error = FSCreateResourceFile（& par，[name lengthOfBytesUsingEncoding：NSUTF16LittleEndianStringEncoding]，（UniChar *）[name cStringUsingEncoding：NSUTF16LittleEndianStringEncoding]，kFSCatInfoFinderXInfo，& info，fork.length，fork.unicode，& ; ref，NULL）; 
 
 if（error == dupFNErr）
 {
 //文件已存在;准备尝试打开它
 const char * iconFileSystemPath = [[path stringByAppendingPathComponent：@\000I\000c\000o\000n\000\r] fileSystemRepresentation]; 
 
 OSStatus status = FSPathMakeRef（（const UInt8 *）iconFileSystemPath，& ref，NULL）; 
 if（status！= noErr）
 {
 fprintf（stderr，error：FSPathMakeRef（））返回％d的文件\％s\\\\
 ）status，iconFileSystemPath）; 
 
} 
} else if（error！= noErr）
 {
 return NO; 
} 
 
} 
 else 
 {
 BlockMoveData（& par，& ref，sizeof（FSRef））; 
 if（FSCreateResourceFork（& ref，fork.length，fork.unicode，0）！= noErr）
 {
 // test 
 
 if（FSOpenResourceFile & ref，fork.length，fork.unicode，fsRdWrPerm，& refnum）！= noErr）{
 return NO; 
} 
 if（refnum！= kResFileNotOpened）{
 
 UpdateResFile（refnum）; 
 CloseResFile（refnum）; 
 
 if（FSGetCatalogInfo（& par，kFSCatInfoFinderXInfo，& info，NULL，NULL，NULL）== noErr）{
（（ExtendedFileInfo *）（& info.extFinderInfo）） - > extendedFinderFlags = kExtendedFlagsAreInvalid; 
 FSSetCatalogInfo（& par，kFSCatInfoFinderXInfo，& info）; 
} 
} 
 
 //测试结束
 return NO; 
} 
} 
 OSErr errorr = FSOpenResourceFile（& ref，fork.length，fork.unicode，fsRdWrPerm，& refnum）; 
 if（errorr！= noErr）{
 return NO; 
} 
如果（refnum！= kResFileNotOpened）{
 CustomBadgeResource * cbr; 
 
 int len = [tag length]; 
 Handle h = NewHandle（len）; 
 if（h）{
 BlockMoveData（[tag bytes]，* h，len）; 
 AddResource（h，kIconFamilyType，128，\p）; 
 WriteResource（h）; 
 ReleaseResource（h）; 
} 
 
 h = NewHandle（sizeof（CustomBadgeResource））; 
 if（h）{
 cbr =（CustomBadgeResource *）* h; 
 memset（cbr，0，sizeof（CustomBadgeResource））; 
 cbr-> version = kCustomBadgeResourceVersion; 
 cbr-> customBadgeResourceID = 128; 
 AddResource（h，kCustomBadgeResourceType，kCustomBadgeResourceID，\p）; 
 WriteResource（h）; 
 ReleaseResource（h）; 
} 
 
 UpdateResFile（refnum）; 
 CloseResFile（refnum）; 
 
 if（FSGetCatalogInfo（& par，kFSCatInfoFinderXInfo，& info，NULL，NULL，NULL）== noErr）{
（（ExtendedFileInfo *）（& info.extFinderInfo）） - > extendedFinderFlags = kExtendedFlagHasCustomBadge; 
 FSSetCatalogInfo（& par，kFSCatInfoFinderXInfo，& info）; 
} 
} 
} 
 return NO; 
} 
  

I want to badge file and folder with some color(image), any idea how it can be achieved I tried with icon service, it work for files but it is not working with folders.

I saw this behavior working Dropbox (10.4, 10.5 and 10.6)- any idea how can this be done?

The following was very close one for me, but it is not working as expected. http://www.cimgf.com/2008/06/16/cocoa-tutorial-custom-folder-icons/

Is there any other solution other then icon service?

I appreciate any kind of help.

解决方案

The following function is the solution I found for the problem

BOOL AddBadgeToItem(NSString* path,NSData* tag)

{   
    FSCatalogInfo info;
    FSRef par;
    FSRef ref;
    Boolean dir = false;

    if (tag&&(FSPathMakeRef([path fileSystemRepresentation],&par,&dir)==noErr)) 
    {
        HFSUniStr255 fork = {0,{0}};
        sint16 refnum = kResFileNotOpened;
        FSGetResourceForkName(&fork);

        if (dir) 
        {

            NSString *name = @"Icon\r";
            memset(&info,0,sizeof(info));
            ((FileInfo*)(&info.finderInfo))->finderFlags = kIsInvisible;

            OSErr error = FSCreateResourceFile(&par,[name lengthOfBytesUsingEncoding:NSUTF16LittleEndianStringEncoding],(UniChar*)[name cStringUsingEncoding:NSUTF16LittleEndianStringEncoding],kFSCatInfoFinderXInfo,&info,fork.length, fork.unicode,&ref,NULL);

            if( error == dupFNErr )
            {
                // file already exists; prepare to try to open it
                const char *iconFileSystemPath = [[path stringByAppendingPathComponent:@"\000I\000c\000o\000n\000\r"] fileSystemRepresentation];

                OSStatus status = FSPathMakeRef((const UInt8 *)iconFileSystemPath, &ref, NULL);
                if (status != noErr)
                {
                    fprintf(stderr, "error: FSPathMakeRef() returned %d for file \"%s\"\n", (int)status, iconFileSystemPath);

                }

            CustomBadgeResource* cbr;

            int len = [tag length]; 
            Handle h = NewHandle(len);
