Default Chapter 3 - Page 46

I need help on the exercise on Creating Outlets and Actions.

Apparently, I followed all the instruction and when i executed the codes, i got this as part of the alert:

Hello!

Hello, <UITextField: 0x4922E0, frame..... ; text = 'Wei Meng - Lee"...

Any idea on what caused this?

Cheers

When allocating and defining your NSString
Code:
NSString *str = [[NSString alloc] initWithFormat:@"Hello, %@", txtName.text];
did you include the dot operator?

I can recreate your error if the line is
Code:
NSString *str = [[NSString alloc] initWithFormat:@"Hello, %@", txtName];
If this is not the error post your -(IBAction)btnClicked method in a response, in case a typo or error of omission has occurred. It will make it easier to rule out possible causes for the error.
