Truncate a string - objective-c

Question

I have a NSTableView that shows the path of files in one column. When the user resizes the tableview I want the pathname (e.g. /Users/name/testfile.m) to be resized, but I want the end of the pathname (e.g. ...name/testfile.m) to be visible and not the start (e.g. /Users/test/te...) of the path as happens by default. I wrote a function that successfully does what I want to do, but the tableview flickers while redrawing as the user scales the tableview. I think there must be a better, more elegant algorithm for doing this, but I have looked into the documentation for NSString and on Stackoverflow and I cant find anything that gives a better solution. If anyone has a more elegant solution to this problem that would be greatly appreciated. Thanks! Cheers, Trond
My current function:
-(NSString *) truncateString:(NSString *) myString withFontSize:(int) myFontSize withMaxWidth:(NSInteger) maxWidth
{
// Get the width of the current string for a given font
NSFont *font = [NSFont systemFontOfSize:myFontSize];
CGSize textSize = NSSizeToCGSize([myString sizeWithAttributes:[NSDictionary dictionaryWithObject:font forKey: NSFontAttributeName]]);
NSInteger lenURL =(int)textSize.width;
// Prepare for new truncated string
NSString *myStringShort;
NSMutableString *truncatedString = [[myString mutableCopy] autorelease];
// If the available width is smaller than the string, start truncating from first character
if (lenURL > maxWidth)
{
// Get range for first character in string
NSRange range = {0, 1};
while ([truncatedString sizeWithAttributes:[NSDictionary dictionaryWithObject:font forKey: NSFontAttributeName]].width > MAX(TKstringPad,maxWidth))
{
// Delete character at start of string
[truncatedString deleteCharactersInRange:range];
}
myStringShort = [NSString stringWithFormat:#"...%#",truncatedString];
}
else
{
myStringShort=myString;
}
return myStringShort;
}

The typical approach would be simply:
[tableViewCell setLineBreakMode:NSLineBreakByTruncatingHead];
As Dondragmer noted, this property may also be set in Xcode's NIB editor.
