Hi,
I'm using CocoaHTTPServer to upload files from computer to iOS devices. But
the result NSData received from the browser is multipart form data, which is
really hard to parse manually. I know I can write a parser from scratch,
however, it's time consuming and bug prone. I'm wondering wether there's a
sophisticated library/framework for this. Any help would be appreciated.
Thanks in advance.

Use of Application nib file template
One of the file templates for iOS UI is Application, described as, An Interface Builder document suitable for creating an iOS application, including an application delegate and window. Problem is, I don't see how to use it. I tried making it the main nib file (via info.plist), but my app throws an exception in UIApplicationMain(), without logging any information indicating what's wrong. In the past, I've had nib files for the main window (main nib via Info.plist), and the file's owner is the application, indicating it's already created.

Subclassing IKImageView
Hello, I want to modify IKImageView so that it erases with the window background color. By default it erases with medium gray which looks awful. I tried implementing -drawRect but this is only called when the window opens. It isn't even called when the image is set to nil. Can one set the erase color of an NSView?

NSURL’s now deprecated -propertyForKey: method existed long before any of
those NSURL*Key constants did, so it’s difficult to imagine what could have
been passed to it other than HTTP response header field names.
At any rate, this should do what you want:
NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:url];
req.HTTPMethod = @HEAD;
[req setValue:@ forHTTPHeaderField:@Accept-Encoding];
void (^completionBlock)(NSURLResponse *resp, NSData *data, NSError *error) =

Re: Drag and drop in collectionview
If you are just trying to rearrange things in your list, you do not need to
get involved with the pasteboard. Rearranging arrays (or ordered sets) is a
little tricky, especially if you want to drag a dispersed collection to a
specific location which is in or after the extent of the selection. You have
to figure out how first removing the objects affects your insertion index,
then insert them back in at the modified row index. Note that if you are
using table bindings, you want to operate on the original array which your
array controller manages, then let the bindings update the table.
I just did this (in a viewController) last night for an NSOrderedSet using the
following:
- (void) moveSelectedObjectsToRow:(NSUInteger)row {
NSIndexSet *indexes = [(NSArrayController*)self.representedObject
selectionIndexes];
NSRange rangeAbove = NSMakeRange(0, row); // Range of all objects above
row in table.
NSUInteger numAbove = [indexes countOfIndexesInRange:rangeAbove]; // Num
selected above row in table.
NSUInteger newRow = row - numAbove; // Where we move selection to.
[self.parentBase moveSublistObjectsAtIndexes:indexes toIndex:newRow]; //
Replace this for Arrays.
}
Using an array instead of an orderedSet, the last line will be different. At
that point, you need to move the selected objects from the array into a temp
array, then reinsert at ³newRow². None of this involves the pasteboard.
I wish they would include a method to do this, but even the ³move² method in
NSMutableOrderedSet does not do what is typically wanted, at least without
doing the above yourself.
Follow up : Reading some more, I've found that I could just use a custom
representation for my objects, containing their index in the model array, to
write to the pasteboard, and then use that index to perform to move when the
dragging session is accepted. On 28 Jan 2012, at 13:35, Luc Van Bogaert
wrote: I'm implementing drag and drop for a NSCollectionView. The idea is
to rearrange objects in the collection by dragging them to another location.
Having read the docs for NSCollectionViewDelegate and NSPasteboard, I still
have a few general questions about the concept.

NSLayoutManager's setDefaultAttachmentScaling: not working in custom PDF NSContexts.
I have an issue where using NSLayoutManager's
setDefaultAttachmentScaling:NSImageScaleProportionallyDown doesn't seem to work
if I setup my own NSGraphicsContext + CGPDFContext.
The problem is that large inline images are not scaled down when drawn like
they would be in an NSTextView. Text after the image is positioned as if it
was scaled though, so I end up with text that is drawn over an image.
Here's the abbreviated code for what I'm doing:
.. make a CGPDFContext ctx, wrap it up in a flipped NSGraphicsContext
.. load an NSTextStorage contents up with my RTFD file
NSLayoutManager *layoutManager = [[[NSLayoutManager alloc] init] autorelease];
[contents addLayoutManager:layoutManager];
[layoutManager setDefaultAttachmentScaling:NSImageScaleProportionallyDown];
BOOL clipped = NO;
do {
CGContextBeginPage(ctx, box);
CGContextTranslateCTM( ctx, 0, box.size.height);
CGContextScaleCTM(ctx, 1.0, -1.0 );
NSTextContainer *textContainer = [[[NSTextContainer alloc]
initWithContainerSize:box.size] autorelease];
[layoutManager addTextContainer:textContainer];
[layoutManager ensureLayoutForTextContainer:textContainer];
NSRange glyphRange = [layoutManager
glyphRangeForTextContainer:textContainer];
NSRange charRange = [layoutManager characterRangeForGlyphRange:glyphRange
actualGlyphRange:nil];
[layoutManager drawGlyphsForGlyphRange:glyphRange atPoint:NSZeroPoint];
clipped = (NSMaxRange(charRange) [contents length]);
CGContextEndPage(ctx);
}
while (clipped);
.. cleanup
I've got some very simple sample code which reproduces the behavior here:
http://gusmueller.com/stuff/NSLayoutImageScalingPDFProblem.zip
Can anyone shed some light on what I'm doing wrong?
This is on 10.7.2 btw.
thanks,
-gus

Sensitivity of swipe gesture
Somewhat off-topic for Cocoa -- but In Lion 10.7, the swipe gesture is a nice feature of the mouse. However I find that frequently the mouse wants to swipe pages when I just want to scroll the page. When that happens the page has to settle down before anything else can be done. Kind of annoying. Is there any sensitivity preference or whatever for the swipe gesture?

iCloud On OSX - Cannot save changes
On iOS iCloud is easy. On OSX I don't know what the problem is. Ok.. First I had a document on my computer. The using the setUbiquidous method I moved it to iCloud. It is on iCloud, and readable. But thats the problem. I have read only access to it from the Mac App. When I open the document I use : self.document = [[NTPDocument alloc]initWithContentsOfURL:iCloudURL ofType:@MyDataType error:err]; NTPDocument is my subclass of NSDocument. and only implements the dataOfType and readFromData. It also returns YES for autosaves in place. And that's hitch #1. When It attempts to autosave I get an error window in the app that it could not auto save the document because I do not have permission. When I try the saveToURL:ofType:forSaveOperation:completionHandler: I get an Unimplemented core routine error (code -4) I have absolutely no clue what this means and cannot for the life of me find the information in the documentation on how to open the file for read/write access. I cannot find a flag or entitlement anywhere that I am missing for allowing me to write to the icloud document... I have attempted to just use [self.document saveDocument:nil] out of desperation but nothing saves, and no error. The main thing being that no matter what way I try to save, my document is never asked to encode the document data. I'm at a loss... Is there possibly an example of working code? Or some part of the documentation that I've not found? I foolishly thought this would be a simple matter of porting my iOS code...

{
return [NSArray arrayWithObjects:(id)kUTTypeJPEG, (id)kUTTypePNG,
(id)kUTTypeTIFF, nil];
}
- (NSArray *)fileTypeNames
{
return [NSArray arrayWithObjects:@JPEG, @PNG, @TIFF, nil];
}
The popup should display the names, but I want the selected item bound to
fileType which is one of the UTIs. By my reading of the documentation, this
_should be very simple_.
Bind:
content - fileTypes*
contentValues - fileTypeNames
selectedObject - fileType
So content provides the list of objects, contentValues provides the
corresponding titles for each object, selectedObject determines which object is
selected. Sounds simple, never works. I've never been able to figure it out. It
seems that if contents provides an array of *strings*, those strings are use as
the titles *no matter what*.
The documentation for content says: Unless contentValues is also bound, the
titles of the items in the NSPopUpButton are derived by invoking description
for each of the content objects, the documentation for contentValues says An
array of strings that are displayed as the items in the NSPopUpButton, but no
matter what on earth I try, it will not work. If I have content bound to, say,
an array of dictionaries, the popup uses contentValues to display the titles.
So what gives? This should be dead simple and for the life of me I can't figure
it out.
Thanks.
*(The docs say content should be bound to an array controller — Not sure why
it says that. An array appears to work the same as an array controller when I
try it. I've tried creating an array controller bound to fileTypes and binding
the popup's content to the ac.arrangedObjects but it still doesn't change the
title situation.)

If I have content bound to, say, an array of dictionaries, the popup uses contentValues to display the titles. I dunno, but I think the bindings should be like this: content - fileTypeNames contentObjects - fileTypes selectedObject - fileType The issue of 'content' providing titles instead of 'contentValue' if it contains strings -- that sounds like a bug, or one of those bug-like design decisions. If the documentation says 'content' should be an array controller, I'd be inclined to do it, but who can tell. If you just want to bind to an an array, you can bind to contentValues instead, and leave 'content' unbound (but in that case you don't get to bind 'contentObjects'). ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
