I am confused too. All of a sudden there are additional classes with code. How were they created and what is in the code? I wish I could read the code but with the black background it makes it very hard to see the words so I cannot transcribe it. Source code would be very helpful.

Very hard to follow along and without the missing steps it takes a great tutorial generally useless.

Thanks anyhow Mohammad

@tree502 The AddCustomerViewController and CustomerViewController are simply view controller files. AddCustomerViewController is a subclass of UITableViewController since it uses static UITableCells. After creating these files you simply select the scene from the Storyboard and assign it a particular view controller.

@azamsharp Exactly!!!!! how to assign storyboard to the view controller. That's what I came to this video for but you have skipped it....

[azamsharp]

@robertlam18 Hi, Just select the Storyboard story. When you select it a blue rectangle will appear on all the edges. Now, in the properties windows (window in the right pane) set the class to your custom view controller. Simple!

@murraypoopchin i uploaded a zip of my Xcode project, as far as i was able to get given the current video, to my minus.com account. min.us/mmHvrGrlr#1o

Followed video's code, filling in blanks as best I could. Why is self.firstNameTextField is returning null?

NSLog says:

- newCustomer created: -Customer: 0x6c137b0-

- [self] set to -AddCustomerViewController: 0xca01320-

- self.firstNameTextField set to (null)

inside -save method: NSLog(a"newCustomer created: %a", newCustomer); NSLog(a"self set to %a", self ); NSLog(a"self.firstNameTextFiel­d set to %a", self.firstNameTextField );

@iapple8037 try putting this in Customer.h:

@property (nonatomic, copy) NSString *firstName;

@property (nonatomic, copy) NSString *lastName;

and this in Customer.m:

@synthesize firstName, lastName;

@robertlam18

- In Storyboards, select the Customers Table View (so blue border shows up around it)

- In the Xcode interface, in the right pane window (the Utilities pane) click on Identity Inspector icon at the top

- Under Custom Class click the drop down menu button, it should now show your AddCustomerViewController and CustomerViewController classes

- for Customers Table View choose CustomerViewController from the drop down

- repeat for Add Customer Table View

[murraypoopchin]

- File > New File

- choose "Cocoa Touch" > "UIViewController subclass", click NEXT

- AddCustomerViewController for Class name

- UITableViewController for Subclass Of

- uncheck create "Targeted for iPad" and With .XIB file for user interface"

- click NEXT, click CREATE (saves your class files in the same directory as the rest of your classes)

- this generates a AddCustomerViewController.h and AddCustomerViewController.m file for you

- repeat for CustomerViewController

You are a teacher who is in my dream. thank you so much Mohammad.

[robertlam18]

you are just typing away without explaining what the object or function is and where it came from e.g. segue.identifier. did you create this ?

[robertlam18]

went through it several times but still don't understand how to pass variable between views.
