Here's the block of surrounding code:
NSFont *ageStarTextFont = [NSFont fontWithName:@"Arial Bold"
size:KRLesserDimensionOfRect(transientDrawingRect)/3];
NSMutableDictionary *txtAttributes = [NSMutableDictionary
dictionaryWithObject:ageStarTextFont
forKey:NSFontAttributeName];
/* Add a white outline attribute for readability */
// NSColor *textStrokeColor = [[NSColor whiteColor]
colorWithAlphaComponent:0.7];
[txtAttributes setObject:[NSNumber numberWithFloat:-6.0]
forKey:NSStrokeWidthAttributeName];
[txtAttributes setObject:textStrokeColor
forKey:NSStrokeColorAttributeName];
/* Draw the string for the age star in the grid */
NSString *ageStarInfo = [portent.ageStar stringValue];
[ageStarInfo drawCenteredInRect: centerBox
withAttributes: txtAttributes];
Any ideas?
Thanks,
Kevin

be careful with clang, sometimes is missing point,
your problem is coming not from this @"Arial Bold",
give the complete stack and explain what is the condition of the leak
False/positive: I have an extensive use of perf tools since years and
I didn't see that since a while
the leak can be deeper than your app === give the complete stack-
trace

Whoops, I thought that I'd also mention that I've run the code
though the
clang static analyzer and it doesn't report that there are any
bugs. I'm
also happy to post more code if it will help.
Thanks again!

Hi everyone, I'm auditing my app and the both the "leaks" command
line
tool and the Instruments tool are both reporting that I have
NSString leaks.
All of the leaks are coming from code similar to the following:
NSFont *ageStarTextFont = [NSFont fontWithName:@"Arial Bold"
size:KRLesserDimensionOfRect(transientDrawingRect)/3];
I'm guessing that the string in question is the @"Arial Bold"
since it
that is the only string on that line, but from what I understand a
string
created like that doesn't require a -release message. Could these
be false
positives generated by the leaks tool, or is there something that
I'm
missing?
Thanks for any pointers!
