Re: The cost of using objects rather than plain C variables
Hi! Sorry for this late answer, I was a bit swamped lately. NSData wouldn't let you, but NSMutableData would, with methods like appendBytes:length:, appendData:, increaseLengthBy:, etc. The underlying buffer might have to move around if it cannot be extended in place, just as it would if you use C realloc() calls. In fact, I overlooked that completely. I just fear building a buffer from zero to something like 400,000 * 3 * 4 bytes = just under 5 MiB would imply too many moves as you mention. Now, I am anyway moving towards a binary file that would be fed directly into the buffer rather than needing decoding, and partitioning it into several chunks in order to optimize the number of triangles displayed. I think I’ll use NSData to store these chunks. Thanks to all for the precious help!

If you know how large your data will be and want to avoid the realloc cost, you can just create your mutable data using -initWithCapacity: . And even if the size end up to be larger than your initial capacity, the mutable data will do the right thing and increase the capacity.

Problem saving document with my doc icon
OS x Lion 10.7.5, Xcode 4.6.3
In my Document based app I am having trouble saving a document with my document
icon.
The Finder still shows the file with the folder icon.
Here is my code:
- (NSFileWrapper *)fileWrapperOfType:(NSString *)typeName
error:(NSError *__autoreleasing *)outError{
if ([self documentFileWrapper] == nil) {
NSFileWrapper * documentFileWrapper = [[NSFileWrapper alloc]
initDirectoryWithFileWrappers:nil];
// Get the main bundle for the app.
NSBundle *mainBundle = [NSBundle mainBundle];
if (mainBundle != NULL) {
// Get the Document Icon
NSString* theIconName = [mainBundle pathForResource:@GMG
ofType:@icns];
NSImage* theDocumentIcon = [[NSImage alloc]
initWithContentsOfFile:theIconName];
// NOTE: theDocumentIcon actually contains 5 BitMapRepresentations.
// I think I am supposed to extract one of them and use it ???
// If so how? Which one to choose?
// The .icns file has sizes of 256 x356, 128 x 128, 48 x 48, 32 x 32, and 16 x
16 (high res will be added later}.
// This file was created using Grab to get an image and IconMaker to make the
icons from it.
// Preview displays the icons and the Inspector seems to indicate it's correct.
[documentFileWrapper setIcon:theDocumentIcon];
}
[self setDocumentFileWrapper:documentFileWrapper];
}
// add several FileWrappers for images, text, and metaData (as a plist).
. . . .
[[self documentFileWrapper] addFileWrapper:imageFileWrapper];
. . . .
[[self documentFileWrapper] addFileWrapper:metaDataFileWrapper];
return [self documentFileWrapper];
}
// This all works as expected except for the document icon.
The myApp-Info.plist has Icon file set to GMG.icns and the Document Type Item
0 Icon File Name set to GMG.icns
TIA for your help
Peter

The Finder still shows the file with the folder icon. You don't need any code to accomplish this. Just make sure your Info.plist has a documentTypes entry for the filename extension you’re using for your bundle, and that the entry notes that it’s a bundle, and points to a valid icon file. —Jens ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

realizeClass crash

Look for those which are neither Apple's nor part of your app. A little explanation. I think Ken is suspecting that this one user has some kind of code-injecting system hack, which is misbehaving, installed on this one Mac. Since this crash is occurring in a base-class +initialize method, that's worth considering in this case. There wouldn't likely be any user data involved at that early stage. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
