While doing some cleanup of memory problems on our software, I
discovered that HIThemeGetTextDimensions seemed to be leaking memory.
(At minimum, it seemed to be allocating a CFString and a CFDictionary and
never fully releasing them). This seems to be an old Carbon-era function
which is poorly documented and has been a probably even before I found
that it was leaking. (We have a multi-threaded application and it seems it
doesn't work properly unless run on the main thread, which never made any
real sense). Is there a more modern and well-behaved alternative to this? I
can't seem to find one.
(Code in which it's used)
-(IBAction) textsize:(id) view
{
CGFloat cgwidth;
HIThemeTextInfo textinfo;
textinfo.version = 1;
textinfo.state = kThemeStateActive;
textinfo.fontID = kThemeSystemFont;
textinfo.horizontalFlushness = kHIThemeTextHorizontalFlushLeft;
textinfo.verticalFlushness = kHIThemeTextVerticalFlushCenter;
textinfo.options = 0;
textinfo.truncationPosition = kHIThemeTextTruncationNone;
textinfo.truncationMaxLines = 1;
HIThemeGetTextDimensions(itsString,0,&textinfo,&cgwidth,NULL,NULL);
itsWidth = cgwidth;
}
Best regards,
