I found the following configuration useful when logging to an NSTextView
instance
[[_textView layoutManager] setBackgroundLayoutEnabled:YES];
[[_textView layoutManager] setAllowsNonContiguousLayout:YES];
I also add the following in an NSTextView subclass to append a string and
scroll it visible.
- (void)addStringAndScrollToVisible:(NSString *)string
{
NSRange endRange;
@try{
endRange.location = [[self textStorage] length];
endRange.length = 0;
[self replaceCharactersInRange:endRange withString:string];
endRange.length = [string length];
// note that this method can be very slow for large amounts of
text.
//depending on how the textview is configured
[self scrollRangeToVisible:endRange];
} @catch (NSException *e){
NSLog(@"Exception scrolling NSTextView: %@", [e name]);
}
}
