Understand and use data models, validation and consistency checks
Apple's Core Data Framework is a collection of classes and concepts
relating to the management of object counts and their persistence. The
problem faced to the beginners and experienced programmers is that you
can not incorporate bit by bit, but you have to understand that from the
beginning the whole thing. This training video satisfied with its steep learning curve this purpose and leads you to experience quick success.
This
video tutorial will start with an application that still does not use
Core Data, but the interplay between UITablerView, NSMutableArray and
NSMutableDictionaries explained using the example of a grouped-do list.
You will learn concepts such as NSPredicate and NSSortDescriptor already
know, the building blocks play an important role in connection with the Core Data framework.
Then
you will examine together with your trainer, piece by piece, the
individual concepts and classes, will see how Xcode supports you in
creating a data model and the possibilities of validation and consistency checks up to generate Objective-C classes exist.
In addition to the processing of the data model with the standard tools of Xcode demonstrates this tutorial how you can create on the XML level, new data models, how you can read any errors in order to generate meaningful dialogue and instructions for app users, such as versioned data models and migrate and how the data is physically stored.

What is Core Data?
Learn
first principle, structure and description of the object model of the
Core Data framework for OS X and iOS know you better.
Building an application
The basic structure of a new application based on an Empty Application template without the use of Core Data is shown. Here, a storyboard will be adjusted according to individual requirements.
Create a data model
The Model View Controller is an important part of software development in iOS. The data model contains a method that returns a binding instance, is working with the entire application.
Entities
Individual
groups are referred to as entities in Core Data, which have several
different attributes. These are to be compared with classes in
object-oriented programming.
Attributes
For
the definition of the type of an attribute in Core Data are many
different options available. These include various numeric values and
string, binary and convertible types.
Better understand Core Data
SQL
statements, which involve communication between Core Data and SQLite
are indicating. When processing records should always be working with
versioned data models in order to prevent to any problems.
Changes to the data model and rates
Existing records can be updated or deleted at any time. The use of versioned data models prevents problems with changes to the original data model. Relationships make it possible to bind data to an already existing object.
Expand generated classes
Already
generated classes can be expanded in Core Data in different ways. These
include the adding methods and deriving a class and the use of
Categories.
Example application based on Core Data
The sample application is created through the construction of the data model,
the implementation of helper methods and the design of graphical user
interface on Core Data base and then provided with records.
Add Storyboard
The
application is added to a storyboard for the design of the graphical
user interface. This is provided with two table view controllers, which
can be adjusted as desired.
Simply create objects
Get
to know an easy way to generate Core Data with a new record and save
it. This option is not recommended for professional use.
Search and validation
The
application adds a search bar to search for individual records. For
this, various filter conditions are established. Additionally be added
to the compulsory completion of certain fields and to define a minimum
and maximum length for the text some validations.
Edit data model using XML
The definition of a Core Data data model is also stored in an XML file which can be edited at any time using a text editor.
The project files are missing!
