I have a TextView which can be messed up via buttons (e.g. set a new font) but
which should keep showing the same range.
Like:
- (void)applyNewFont: (UIFont *)f
{
NSRange visibleCharacterRange = self.textView.visibleRange;
self.textView.font = f;
[ self.textView scrollRangeToVisible: visibleCharacterRange];
}
The problem: I cannot find anything like visibleRange or visibleRect.
Any workarounds?
Gerriet.
P.S. On OS X I would do:
NSRect visibleRect = [ self.textView visibleRect ];
NSRange visibleGlyphRange = [ layoutManager glyphRangeForBoundingRect:
visibleRect inTextContainer: textContainer ];
NSRange visibleCharacterRange = [ layoutManager characterRangeForGlyphRange:
visibleGlyphRange actualGlyphRange: NULL ] ;
