How to use nsxmlparser in Iphone SDk?

-
Image
NSXMLParser is a forward only reader or an event driven parser. What it means is, an event is raised whenever the parser comes across a start of an element, value, CDATA and so on. The delegate of NSXMLParser can then implement these events to capture XML data. Some of the events are raised multiple times like the start of an element, value of an element and so on. Since NSXMLParser is known as an event driven parser, we can only read data at the present node and cannot go back. The iPhone only supports  NSXMLParser  and not  NSXMLDocument , which loads the whole XML tree in memory. Books Application To understand how to use an instance of NSXMLParser, let’s create a simple navigation based application where we will list the title of the book in the table view and upon selecting a title, display the detail information in a detail view. Click  here  to see the sample XML file, used in this application. Create a new application in XCode by selecting Navig...

About Xcode 4 features

Image
Xcode 4 is the latest iteration of Apple’s integrated development environment (IDE), a complete tool set for building Mac OS X and iOS applications. The Xcode IDE includes a powerful source editor, a sophisticated graphical UI editor , and many other features fromhighly customization builds to support for source code repository management. Xcode can help you identify mistakes in both syntax and logic, and will even suggest fixes. Xcode 4 features a single window, called the  work space window , that holds most of the data you need. A second window, called the  Organizer window , is used for organizing your projects and reading documentation. For iOS projects, the Organizer window is also used to manage  devices. Xcode 4 has many features to make your job easier.          Xcode 4 has a single-window interface for all major workflows (you can have multiple workspace windows and multiple tabs per window)....

Blocks in iPhone?

-
As a programmer, you’re used to data types like   String , which is a variable type for text. We also are aware of things like   int ,   float , and   double , which are variable types to store numeric values. Finally, we know about things like   NSObject , which is a foundation level class that allows us to bundle various collections of both data types and methods (a.k.a. functions). Blocks bring something significantly different to the table, providing a data type for executable code storage. If that doesn’t make sense to you, don’t worry: blocks can be tough. Their purpose and function becomes much more clear upon seeing examples of their use. One of the most popular types of patterns in which blocks are used is for providing “completion blocks” to objects who perform some kind of asynchronous operation. The following is an example of a method signature provided in my UIView that takes advantage of accepting a completion block from a user: + (void)animat...
