To manage the keyboard that pops up during input, don't forget to make the controller a delegate of the text fields and then insert the following code right before @end of your source file.
- (BOOL)textFieldShouldReturn:(UITextField *)theTextField { [theTextField resignFirstResponder]; return YES; }Once your app is working, compress the project folder and rename the zip file lab2-idnumber.zip. Submit that zip file via moodle.
