In this tutorial, we edit user data and delete attributes. We save the modified NSManagedObject's attributes in Core Data, and we delete the objects too at the appropriate NSManagedObjectContext. 

Our goal to save User Entity’s Name (userName-string) and the type of the user, so the Type Entity’s Name (typeName-string), and FetchRequest in UITableViewController the user name and the type Relationship’s Name attribute.

Sometimes it's very useful to check, which UIFonts are already available, and which should be imported. In this little tutorial, I will show, how can you import your own custom Font, and how can you check the available fonts in your Xcode Project.  IOS 9.3 Xcode 7.3

First of all, in this tutorial we need to create Hobby Entity, and for this we need to change the Core Data model. After that, we can create and save hobbies to users. Finally, we learn to use SortDescriptor and NSPredicate. 

In this Xcode 6, IOS 8 Core Data Tutorial, we create first of all the ManagedObjectModel. First we create a SingleView Xcode project, and set the Core Data, Entities and Relationships. Finally we set the delete rules too.

When you need to change your Core Data Entities or structure, you have to add new model version before you send your App in AppStore. If you change just attributes or fetched templates, it’s not needed, you can do it without consequence. But if you want to add a new Entity, you have to migrate your persistent store to a new model version. You should also set mappings for the migration. In this tutorial, we add model versions, model mappings, and using Lightweight Migration.

In this tutorial we add model versions, model mappings, and using Lightweight Migration.In this tutorial we create 2 UIViewController With 1-1 UIButtons and Embed UINavigationController. After that we create Custom Segue, and send data to SecondViewController, finally we set the UnWindSegue too. This tutorial is a Basic Settings tutorial, which was made IOS 8 and Xcode 6.

This tutorial help to do basic settings, before we do specific exercises. I did this for help myself. :) At the next Tutorials, I will just link it, and not write again and again the basic settings at Storyboard, as creating new UIViewController, new CocoaTouch files, or embed UINavigationController and add UIBarButtonItems.

In this Xcode 6 and IOS 8 UITextField Animation tutorial, we create a fade in & out animation, and with 2 UITextField we create dimming and lighting CABasicAnimation when the Textfield become FirstResponder, and when the user end editing. It could be very useful if you would like to create a nice interface animation for a basic form. 

 After basic settings we set UINavigationBar colors and clear background image, and set our own separator line with an image. After that, we create Navigation Bar UIBarButtonItems programmatically and set their color too. Finally, we show and hide UINavigationBar at switching between ViewControllers, and hide StatusBar. These are very useful things, which can be present nice solutions.
