This worked once I did the same for one of the four other library classes that SplitsTestSet used. As my projects use all the classes the library provides, I'll stick to the -ObjC linker flag solution; adding code to solve what seems to be a problem with over-enthusiastic link optimisation is anathema to me. However, this solution would definitely be worth using if I was using only a tiny fraction of a large library. > Also try looking at the binary using the ‘nm’ tool to check whether the class > symbols exist in the app. Yes, this made it crystal clear - thanks for pointing me at 'nm' and helping me understand the solutions.

You didn't show the relevant code. (Your code above performs a couple of
unnecessary copies).
On Lion 10.7.2, using Xcode 4.2.1 with default Foundation Template, this works
for me:
int main (int argc, const char * argv[])
{
@autoreleasepool {
CFStringRef input = CFSTR("\n"
"Links/lets&dance.jpg\n"
"0\n"
"\n"
"\n"
"Links/doubles_1/lets&dance.jpg\n"
"0\n"
"");
NSLog(@"input:\n%@\n\n", input);
CFStringRef firstOut = CFXMLCreateStringByEscapingEntities(
kCFAllocatorDefault,
input,
NULL);
NSLog(@"output:\n%@\n\n", (id)firstOut);
NSString* format = @"\n"
@"4_2\n"
@"%@\n"
@"";
NSString* second = [NSString stringWithFormat:format, (id)firstOut];
CFStringRef secondOut = CFXMLCreateStringByEscapingEntities(
kCFAllocatorDefault,
(CFStringRef)second,
NULL);
NSLog(@"secondOut:\n%@\n\n", (id)secondOut);
CFRelease(firstOut);
CFRelease(secondOut);
}
return 0;
}

Re: NSViewController KVO compliance
Unfortunately, if the doc doesn’t mention it specifically, don’t assume that it is and always will be, even with evidence. You can check the headers to see (and if there is a mismatch, mention it in a bug) File a bug asking for clarification. which you have. This goes for all hopefully-KVO compliant properties. Sending a bug that says please document all KVO-compliant properties isn’t necessary (or really helpful) because that’s in progress as we come across them. But on a per class basis, if you’re not sure about a property, go and file the bug. And a single bug for multiple properties in a class is fine, so Kyle didn’t need to knock himself out. :-) But thanks for filing.

NSBeep() is being called by -beginSheet:modalForWindow:... . Compiler
optimization ("tail-call optimization") means that the -beginSheet:... frame is
absent from the stack trace.
-beginSheet:... calls NSBeep() in some error case. I don't understand the code
myself, but I'd guess that it's complaining because there's already a sheet
open on that window. Perhaps you're calling -beginSheet: twice, and the first
call works and the second call just beeps.
You should file a bug report asking for -beginSheet:... to log a real error
message or throw an exception instead of beeping.

NSComboBoxCell drop down programmatically
Is it possible to simulate that a user clciks an arrow in NSComboBoxCell in NSTableView? I mean to do this programmatically? I have an application that have the requirement that the line of the NSComboBoxCell is to be selected, and the have the comboboxcell drop down. the selection part of it was easy, but i can't find any method to make the combo cell to open.___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

NSToolbar breaks auto layout constraints of NSSplitView in window
I have a .xib file that uses auto layout. I setup a window with a sidebar using NSSplitView and NSOutlineView. Everything was working well with resizing the window until I added a NSToolbar. Things continued to look good when I resized the window in IB but not when the app is run. When the window's height is resized, the split view is no longer pinned to the top of its superview. I tried the same thing in a window of another .xib file and got the same result except that this time it was the bottom of the split view that was no longer pinned. Adding user defined constraints did not correct the problem. Removing the toolbar results in proper behavior again. Has anyone else experienced this problem? Am I missing something obvious? Any ideas for a workaround? Thanks for your help. using Xcode 4.2.1.

Alternate Framework location
Hello, I've been reading through the developer docs and I'm not sure I can do what I want so I thought I would ask. I have created a Foundation tool and I have created a private framework. All works great if I install my framework in /Library/Frameworks. What I would like to know is, can I install my framework in /usr/local/frameworks as an example and have my foundation tool automatically find it? I would assume I would have to add a search path or something but I'm not sure where.

If the framework will always be installed in /usr/local/frameworks, then this is easy enough: you can set the framework's install path to any path when it is built. When something is linked against that framework, the framework's install path is stored in the tool so that it can find the framework at runtime. There are some magic values you can use in the path to help out; see the end of the dyld man page: http://developer.apple.com/library/mac/documentation/Darwin/Reference/Manpages/man1/dyld.1.html If you want the tool to search in multiple places at run time for the framework, that's harder. There are a couple of ways to arrange for that, but the easiest way is for the tool to actually live inside the framework (or at a known location relative to it), use the @executable_path or @rpath variable to find it, and in bin you can put either a symlink or a shell script to invoke the tool at its installed location. The shell script could alternately find the framework using whatever algorithm you like and then set DYLD_FRAMEWORK_PATH before invoking the real tool. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
