Ok so yesterday I had some trouble with this error, turned out I just needed to be patient and read through more of the book. This time I have got to the end of the project and I am getting this error at a different point.
I have isolated the line of code causing the issue but I’m not sure what the issue is!
htmlString=[htmlString stringByAppendingString: appDelegate.savedNumber];
Debug console is saying:
2012-08-09 13:06:47.235 tester[1357:c07] * Terminating app due to uncaught exception ‘NSInvalidArgumentException’, reason: ‘* -[__NSCFConstantString stringByAppendingString:]: nil argument’

terminate called throwing an exception
Anyone have any ideas? 🙂
It is because appDelegate.savedNumber is nil (does not set) . And why it is nil this is another question.
