Re: [iPhone] Custom -sizeWithFont: and CGContextRef question
On Jul 16, 2009, at 1:30 PM, Michael Hoy wrote:
Hello all,
For various reasons I'd like to implement a method similar in
function to NSString's -sizeWithFont: (UIKit addition). The
difference is it takes a CGFontRef. Here's a rough idea of the code
(a slight adaptation of Timothy Ritchey's TTFontCell code, and I
apologize because I can't find a link to it right now):
- (CGSize)sizeWithFont:(CGFontRef)font ofSize:(CGFloat)size
withKerning:(CGFloat)kerning {
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetFont(context, font);
CGContextSetFontSize(context, fontSize);
CGContextSetCharacterSpacing(context, kerning);
}
The code works — however, it can only be called within a UIView's
drawRect: method, for a valid context to be returned in
UIGraphicsGetCurrentContext();
This method is only useful really if it can be called *before* the
drawing code, for laying out views and such. I know that I need to
create a CGContextRef and push it on the UIGraphics stack. My
question is, what might be the best way to do this? I see I can use
CGPDFContextCreate or CGBitmapContextCreate... which makes sense
here? All I need to do is determine the size of a string w/
specified font, not actually draw it.
Working directly from a CGFontRef is often not the Right Thing(tm) to
do primarily because Quartz 2D is not the best way to draw text.
Quartz 2D is really good at drawing glyphs but there's a long road
from characters to glyphs. On the text system, there are public APIs
to Core Text that which handle things like line layout, glyph
substitution, bidi text adjustments etc... On the iPhone you're
largely limited to what you can find in UIKit.
Can you elaborate on why you are working from a CGFontRef instead of
from a UIFont?
If you absolutely MUST work from the CGFont level, you are likely to
have to use routines like CGFontGetGlyphBBoxes and
CGFontGetGlyphAdvances to compute the size yourself.

Re: Cells selection in NSTableView
I need following functionality to be implemented in NSTableView.
Selecting Multiple cells of single column in
NSTableView.
I subclassed NSTableView and created class TestTableView.
I have done following 3 things.
...
3) I created custom class for NSTextFieldCell and overriden following
method
- (NSColor *)highlightColorWithFrame:(NSRect)cellFrame inView:(NSView
*)controlView
{
return nil;
}
Do not override -highlightColorWithFrame:inView:. Instead, override
-setHighlighted: and -setBackgroundStyle: with empty
implementations. Then override -drawWithFrame:inView:, and determine whether
the cell (center point) is inside any selected cell rectangle. If yes, then
-[super setHighlighted:YES], otherwise -[super setHighlighted:NO].

Re: Codesign from Buid Server
On 14 Jul 2009, at 21:12, Richard Holliday wrote: We have a TeamCity build server setup to produce automatic builds for our cocoa application. We also code sign our apps but this part has to be done on a dev box as the build agent (OS X 10.5) doesn’t recognize the certificate in the system keychain (there is no login keychain when the build agent runs the post-build signing script). Has anyone else setup a build server which code signs their apps? Yes. If so, was there a trick to getting the certificate / keychain to play nicely. **Don't** put certificates in the system keychain (I learned this the hard way). You can easily break Server Admin because servermgrd isn't picky about which certificate it uses from the system keychain (it just uses the first thing it comes across, it seems), but Server Admin will throw a wobbly (with some very unhelpful error messages) if the certificate it finds doesn't validate for whatever reason. Instead, why not create a separate keychain to contain your code signing identity. This means you can lock it with a password that you only give out to users who are supposed to be able to trigger the signing step; either that, or if you want anyone to be able to do it, it means you can stick the password in a script without worrying too much (obviously set the permissions on the script according to your requirements). Then you need to do security unlock-keychain path-to-keychain followed by codesign --keychain path-to-keychain -s code-signing-identity thing-to-sign Obviously the unlock-keychain command is going to prompt for the password, so you'll have to arrange to feed it something appropriate. Either that, or use the -p option to pass the password to it (remembering that this will show up in the process list, so you had better not want the password to be secret if you do that).

NSCollection view item not receiving mouse events after redisplay
Hi everyone, I already tried to look for this one on Google, but had no luck. I have in my app a NSCollectionView that displays a sort of calendar of events, represented by custom views. In these views I make the delete X button appear on mouseEntered: and mouseMoved: events. Everything works fine until I delete one of the items. The item disappears and the NSCollectionView moves other items to fill the gap, so another item moves under the mouse pointer. My problem is that this item does not receive mouseMoved events anymore. I have to move the mouse pointer out of the view and then in again to make it work again. I hope I explained it well! Does anybody have some suggestions? Thank you very much.

RE: missing vertical scroll bar

I believe the recipe you want involves shoe-horning the scrollViewRect into its

For an example, look at the DocumentWindowController's resizeWindowForViewSize
method in TextEdit (shown below).
HTH,

- (void)resizeWindowForViewSize:(NSSize)size
{
NSWindow *window = [self window];
NSRect origWindowFrame = [window frame];
if (![[self document] hasMultiplePages])
{
size.width += (defaultTextPadding() * 2.0);
}
NSRect scrollViewRect = [[window contentView] frame];
scrollViewRect.size = [[scrollView class] frameSizeForContentSize:size
hasHorizontalScroller:[scrollView
hasHorizontalScroller]
hasVerticalScroller:[scrollView hasVerticalScroller]
borderType:[scrollView borderType]];
NSRect newFrame = [window frameRectForContentRect:scrollViewRect];
newFrame.origin = NSMakePoint(origWindowFrame.origin.x,
NSMaxY(origWindowFrame) -
newFrame.size.height);
[window setFrame:newFrame display:YES];

Re: iTunes COM interface for Windows; need the equivalent for
I doubt Apple is going to port Cocoa/CoreData to Windows just for iTunes database� Not that I disagree, but what makes you think Cocoa doesn't already work on Windows? Openstep worked on Windows before it worked on Mac OS X. Cocoa is derived from Openstep. Project Builder (the predecessor to Xcode) is a nifty Cocoa application that Apple delivered for the Windows flavor of Web Objects as recently as September 17, 2003. If Cocoa apps from 2003 work on Windows, why would modern Cocoa not compile and run on Windows if Apple wanted it to?

Re: Finding an available port for chat
but there will be persons like myself with draconian isp who block gobs of ports and make it hard to for chat apps to work. There are a lot of very good reasons for a Draconian policy like that. :) how can I, in a reasonably economic way, find an open port to talk on? Are you trying to specify a specific port on your machine you know will get past the ISP's filtering? Or are you just trying to find a random high-numbered port that the ISP will unlikely have blocked? Or are you trying to get around the blocking in general. If you drop down to Berkeley sockets layer, you can specify a port for your server, or you can pass 0 as the port and the server will (somewhat) randomly choose a high numbered port for you. If you think lots of potential users are going to suffer port filtering, you could set up a server somewhere else on the Internet and have both users connect to that. For example, user's A and B connect to each other by connecting to a third machine C. That way neither user A or B need to have their machine open up a server on their machine.

NSTextView without NSScrollView
Is there a way to have an NSTextView that is not enclosed in an NSScrollView? IB doesn't seem to want to let me. It would be for displaying static rich text (certain things are harder, or maybe even impossible, to do with NSTextField). I know I can turn off drawing of the NSScrollView border, but it throws off the layout, because there's a margin around the text, at least on the left. -- James W.

Re: [iPhone] Custom -sizeWithFont: and CGContextRef question
Custom fonts. It's the only way to do it. UIFont does not support

Hello all,
For various reasons I'd like to implement a method similar in
function to NSString's -sizeWithFont: (UIKit addition). The
difference is it takes a CGFontRef. Here's a rough idea of the code
(a slight adaptation of Timothy Ritchey's TTFontCell code, and I
apologize because I can't find a link to it right now):
- (CGSize)sizeWithFont:(CGFontRef)font ofSize:(CGFloat)size
withKerning:(CGFloat)kerning {
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetFont(context, font);
CGContextSetFontSize(context, fontSize);
CGContextSetCharacterSpacing(context, kerning);
}
The code works — however, it can only be called within a UIView's
drawRect: method, for a valid context to be returned in UIGraphics
GetCurrentContext();
This method is only useful really if it can be called *before* the
drawing code, for laying out views and such. I know that I need to
create a CGContextRef and push it on the UIGraphics stack. My
question is, what might be the best way to do this? I see I can use
CGPDFContextCreate or CGBitmapContextCreate... which makes sense
here? All I need to do is determine the size of a string w/
specified font, not actually draw it.
Working directly from a CGFontRef is often not the Right Thing(tm)
to do primarily because Quartz 2D is not the best way to draw text.
Quartz 2D is really good at drawing glyphs but there's a long road
from characters to glyphs. On the text system, there are public
APIs to Core Text that which handle things like line layout, glyph
substitution, bidi text adjustments etc... On the iPhone you're
largely limited to what you can find in UIKit.
Can you elaborate on why you are working from a CGFontRef instead of
from a UIFont?
If you absolutely MUST work from the CGFont level, you are likely to
have to use routines like CGFontGetGlyphBBoxes and
CGFontGetGlyphAdvances to compute the size yourself.

There are a lot of very good reasons for a Draconian policy like that. :) how can I, in a reasonably economic way, find an open port to talk on? Are you trying to specify a specific port on your machine you know will get past the ISP's filtering? Or are you just trying to find a random high-numbered port that the ISP will unlikely have blocked? Or are you trying to get around the blocking in general. If you drop down to Berkeley sockets layer, you can specify a port for your server, or you can pass 0 as the port and the server will (somewhat) randomly choose a high numbered port for you. If you think lots of potential users are going to suffer port filtering, you could set up a server somewhere else on the Internet and have both users connect to that. For example, user's A and B connect to each other by connecting to a third machine C. That way neither user A or B need to have their machine open up a server on their machine.

(As a nearly identical question asked less that a week ago - seriously, do some searching to turn up a wealth of suggestions and comments...): In general, this will only work if the two phones are on the same local network (such as on the wifi). If that's the case, you can just use Bonjour for discovery and it will handle assigning port number. Otherwise, for example, if the two devices are using 3G to connect to the internet, even if they are set up to accept connections, the cell network NAT will disallow incoming connections. More complicated approaches (google tcp hole punching or NAT Traversal) are needed for that (and I'm not sure that those techniques will work across cell networks). You can, however, have both devices connect to the same remote server, and have it forward packets between them, but that approach does not scale well. You're really going to have to do some more research on networking and peer-to-peer connections to understand the ramifications of trying to have one random device talk to another random device.

Public API for AirTunes?
Hi, I've been looking for a public API for AirTunes without success. Maybe I have the wrong name? Is it available under another name? There are a number of apps out now that use AirTunes (VLC, Rogue Amoeba's AirFoil, FireFly and others). Are they all hacking the daap? Daap is pretty well understood at this point and, given that it has been around since iTunes 4, it seems unlikely that Apple would break it, but I'm a little surprised so many released apps are using a private API.

[IB] - how to delete action or outlet?
Hi, All, I have no idea of how to remove an action or an outlet from AppController object, once added. For example, I've created appropriate modules AppController.h and .m, then wrote necessary code lines to declare an action stub and/or outlet. Then I open IB and drag necessary objects, like AppController, a text field or label or whatever else, connect them with AppController and look at the AppController's Info page. I see a header AppController.h and action (as well as outlet), I just created for it. OK. Now I'd like to remove that action and/or outlet. But I can't do it from IB, because - button is always gray unless I'll add a new (yet another) action or outlet. What to do now? I close IB, go to AppController.h and .m and remove the code. Then I open IB again, expecting to see previous action being disappeared... Oops... They're still in place, connected to nothing, but - button in appropriate panel is still gray. I can add a new action or outlet, but those, initially created, will be stay unremovable. Recently I've upgraded XCode to 3.1.3, but have still the same problem. Is this a bug or just my misunderstanding? Thanks. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

But no, the Kind entry shows Plain Text. For the file in question, is the file extension or file type code unique to your app? If other apps also describe the file type, then their kind string might be used in preference to yours. Before the advent of UTIs, the kind string was determined by the CFBundleTypeName value in an element of the CFBundleDocumentTypes array. If both are present, I don't know which takes precedence. Lastly, does a QuickLook Generator really export types, or should it be treated as only importing them?
