Unlike NSMutableString, NSTextView has not implemented a convenient method to append text to its existing text object.

You can append text to an NSTextView by creating a category on NSTextView and using code similar to that shown below:

@interface NSTextView(Controller)

• (void) appendString: (NSString *)str @end

@implementation NSTextView(Controller) -(void)appendString:(NSString *)str { int len = self textStorage] length]; [self replaceCharactersInRange:[[NSMakeRange(len,0)withString:str]; }

Invoke as usual, e.g., (a, b, and c are all declared integer variables)

[reportView appendString:[NSString stringWithFormat:@"%i.%i.%i", a, b, c]];
