Last time, we talk about how to create a Push segue animation without UINavigation controller. The problem I want to solve is that I want to use horizontal sliding effect as ViewController transition without using UINavigation. However, there is no horizontal sliding effect in model segue. Therefore, I have to use custom style segue and define a custom segue. With the custom style segue, we can easily switch ViewControllers without any pain.
In this IOS tutorial, I will show you a new way to apply Push segue by using UINavigationController, but hide the navigation bar. This approach is more clean, nice and easy to understand. It is also very easy for you to use in your own project. Because we are using a normal UINavigator, all view transition are implemented by UINavigationController functions including pushViewController and popViewControllerAnimated.
My working environment is Mac OS X Mavericks with Xcode 5.0.2. Deployment target is 7.0. Target device is iPhone. You can also use this source code in your iPad project. Read more
This is the forth iphone programming tutorial in the iPhone Rss Reader app example. In this iphone source code example, I will improve the xml parser to get more data from rss feed xml, and store them in a new value object class. When user clicks the rss title in the table view, I will use push segue to switch to a UIWebView, which will show the rss content inside.
This tutorial will update the storyboard to add a new UIViewController, and all data in this UIWebView example is generated by the previous iphone example source code. Hence, I recommend you to review the whole example tutorials as well.

Latest Update: A better way to implement push segue animation without UINavigation bar
Apple provides three styles of Storyboard Segue, push segue, modal segue and custom segue. Push segue is a predefined segue with a horizontal sliding animation. To make it works, we have to integrate our view controller with UINavigationController. Sometimes, we don’t want to have a UINavigation Bar, but want to use push segue between viewcontroller transition. We may find that it won’t work. Alternatively, we can use modal segue instead. In modal style, there are four transitions including Cover Vertical, Flip Horizontal, Cross Dissolve and Partial Curl. However, there is no horizontal sliding animation effect. Hence, we have to use custom style segue. Here is a video to show you how we can create a horizontal sliding animation transition by custom segue.
