Hi
I am new to programming with Objective-C and Cocoa and tried to
create a simple test application using what I had learned about
strings from a NSString documentation PDF I had read.
The application is a really simple one. The interface consists of
two NSTextFields and a NSTextView (txtInput, txtFinne and txtOutput)
and a button (btnKlikk). When the user clicks the button the
application uses an NSScanner to get the part of txtInput up to where
it finds txtFinne. The output is then sent to txtOutput.
When the button is hit repeatedly the new information is added at the
bottom of the txtOutput textfield so I tried to do a selectText
before inserting the new text to get rid of the old contents before
adding the new, but I just get the following error and can't think of
a solution:

#import "SPECommunicator.h"
@implementation SPECommunicator
- (IBAction)btnKlikk:(id)sender
{
NSLog(@"%@", @"Knappen ble klikket...");
//Henter det som skal søkes gjennom
test = [txtInput stringValue];
//henter det som skal søkes etter
hva = [txtFinne stringValue];
//setter scanneren til å skanne gjennom teksten som har kommet inn
theScanner = [NSScanner scannerWithString:test];
[txtOutput selectText:self];
//scanner teksten inn i variabelen resultat
[theScanner scanUpToString:hva intoString: &resultat];
//kjører ut resultatet
[txtOutput insertText:[@"Her er originalteksten:\n"
stringByAppendingFormat:@"'%@'\n\nScannet frem til '%@:'\n'%@'\n\n",
test, hva, resultat]];
}
@end
What might be wrong?
