Format Specifiers The format specifiers supported by the NSString formatting methods and CFString formatting functions follow the IEEE printf specification; the specifiers are summarized in Table 1. Note that you can also use the “n$” positional specifiers such as %1$@ %2$s. For more details, see the IEEE printf specification. You can also use these format specifiers with the NSLog function. Platform Dependencies OS X uses several data types—NSInteger, NSUInteger,CGFloat, and CFIndex—to provide a consistent means of representing values in 32- and 64-bit environments.
CodingGuidelinesForCocoa.pdf. ModalViewController presentModalViewController. Shake. Tools and Helpers. iPhone Dev Center - Apple Developer Connection. iPhone Dev Center: iPhone Application Programming Guide: Introdu. This document is the starting point for creating iOS apps.
It describes the fundamental architecture of iOS apps, including how the code you write fits together with the code provided by iOS. This document also offers practical guidance to help you make better choices during your design and planning phase and guides you to the other documents in the iOS developer library that contain more detailed information about how to address a specific task. The contents of this document apply to all iOS apps running on all types of iOS devices, including iPad, iPhone, and iPod touch.
At a Glance The starting point for any new app is identifying the design choices you need to make and understanding how those choices map to an appropriate implementation. Translate Your Initial Idea into an Implementation Plan Every great iOS app starts with a great idea, but translating that idea into actions requires some planning. UIKit Provides the Core of Your App Apps Require Some Specific Resources Prerequisites.
Introduction to The Objective-C. NSUserDefaults Class Reference. Overview The NSUserDefaults class provides a programmatic interface for interacting with the defaults system.
The defaults system allows an application to customize its behavior to match a user’s preferences. For example, you can allow users to determine what units of measurement your application displays or how often documents are automatically saved. Applications record such preferences by assigning values to a set of parameters in a user’s defaults database. The parameters are referred to as defaults since they’re commonly used to determine an application’s default state at startup or the way it acts by default.
At runtime, you use an NSUserDefaults object to read the defaults that your application uses from a user’s defaults database. The NSUserDefaults class provides convenience methods for accessing common types such as floats, doubles, integers, Booleans, and URLs. Values returned from NSUserDefaults are immutable, even if you set a mutable object as the value. NSUserDefaults class reference.

Secu Crypto & network. Network. iPhone Dev Center: Memory Management Programming Guide for Core. Microprocessor architectures commonly use two different methods to store the individual bytes of multibyte numerical data in memory.
This difference is referred to as “byte ordering” or “endian nature.” Most of the time the endian format of your computer can be safely ignored, but in certain circumstances it becomes critically important. OS X provides a variety of functions to turn data of one endianness into another. Intel x86 processors store a two-byte integer with the least significant byte first, followed by the most significant byte. This is called little-endian byte ordering. To give a concrete example around which to discuss endian format issues, consider the case of a simple C structure which defines two four byte integers as shown in Listing 1. Listing 1 Example data structure Suppose that the code shown in Listing 2 is used to initialize the structure shown in Listing 1. iPhone Dev Center: Memory Management Programming Guide for Core. If you need to find out the host byte order you can use the function CFByteOrderGetCurrent. The possible return values are CFByteOrderUnknown, CFByteOrderLittleEndian, and CFByteOrderBigEndian.
Byte Swapping Integers Core Foundation provides three optimized primitive functions for byte swapping— CFSwapInt16, CFSwapInt32, and CFSwapInt64. All of the other swapping functions use these primitives to accomplish their work. In general you will not need to use these primitives directly. iPhone Dev Center: Byte-Order Utilities Reference.
iPhone OS Reference Library. Cocoa Fundamentals Guide. iPhonreDeveloper Program. iPhone Dev Center: Interface Builder User Guide: Introduction. iPhone Dev Center - Apple Developer Connection. iPhone Dev Center: UINavigationController Class Reference. The UINavigationController class implements a specialized view controller that manages the navigation of hierarchical content.
This navigation interface makes it possible to present your data efficiently and makes it easier for the user to navigate that content. You generally use this class as-is but in iOS 6 and later you may subclass to customize the class behavior. The screens presented by a navigation interface typically mimic the hierarchical organization of your data.
At each level of the hierarchy, you provide an appropriate screen (managed by a custom view controller) to display the content at that level. Figure 1 shows an example of the navigation interface presented by the Settings application in iOS Simulator. A navigation controller object manages the currently displayed screens using the navigation stack, which is represented by an array of view controllers. Support - Discussions - [iPhone] Switch UIViews ... Gérer des UIView avec un UIViewController sur iPhone. Nous avons récemment vu comment gérer les bases d’une UIView.
Voyons maintenant comment contrôler les UIView depuis un UIViewController. Comme son nom l’indique, ce dernier permet de contrôler les vues de votre application afin de respecter un minimum le modèle MVC. I] Rapides Rappels sur le modèle MVC En programmation vous avez différentes manières d’aborder un problème. En général une méthode barbare où vous n’architecturez pas vos données se terminera souvent mal lorsque vous souhaiterez améliorer votre application. Sur iPhone, les (UIView)Contrôleurs sont surtout présents pour gérer plus facilement les différentes vues. II] Créer et initialiser un UIViewController Comme dans bien d’autres cas, nous créons une nouvelle classe que nous dérivons. Définition du UIViewController. iPhone Dev Center: View Controller Programming Guide for iPhone. Custom content view controllers are the heart of your app.
You use them to present your app’s unique content. All apps need at least one custom content view controller. Complex apps divide the workload between multiple content controllers. A view controller has many responsibilities. Some of these responsibilities are things that iOS requires the view controller to do.
