App works - still has some issues to be smoothed out, but basic functionality is available:

• Add items (and persist)
• Edit items (and persist)
• Reorder items
• Delete items (Note: includes two types - swipe in non-edit mode and delete in edit mode)

Also included CocoaPods.

I'd also like to refactor the code to move the button logic to utility methods.

John,

This submission was very borderline. You need to start earlier. Or, if you don't have the time, I recommend you follow the class as an observer.

Your finishEdit: method should not be implemented like that. This is an extremely brute force mechanism and would have major performance issues in production. As I mentioned in the hints in the assignment description, you need to be tracking the UITextField delegate methods and keep your underlying array up to date. Also, you didn't implement persistence in this app.

Please implement the saving/restoring todo items by Friday. Use either NSUserDefaults or file I/O, NSArray has a built-in helper to load/save itself to disk. NSUserDefaults is a very commonly used tool, you should practice using it.

The next level is to be able to implement the multi-line to do item. It's an illustration of what it takes to really fine tune a UI. It's an intermediate level task. Not incredibly difficult, but may take you as long as the rest of the assignment.

Here's my checklist of things I'm looking at when I'm reviewing this project.

• Is the Objective-C code styling consistent with standards?
• Did you create a custom cell or use tableview prototypes? Either approach is fine.
• In your custom cell, did you configure the Auto Layout properties? Or, if you didn't use AutoLayout, did you set the autoresizingMask to UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth.
• How did you sync the UITextField changes with the underlying array of todo items? There are many options:
  • Set the view controller to be the delegate of each UITextField. Track the index of the UITextField using the tag property or objc_getAssociatedObject/objc_setAssociatedObject.
  • Set the cell to be the delegate of the UITextField and create a custom cell delegate.
• How was persistence implemented?
  • NSUserDefaults
  • File system
