iOS App Development: how to Create Amazing Applications
In case you want to build iOS apps, you have to understand the foundation of Xcode integrated environment, programming language the - Objective-C, the Cocoa app programming interface, and the UIKit. Our iPhone application developers have come up with this guide to assist you in starting development and will help you to better comprehend the environment itself.
Subscribe to the Apple Application Developer Program
First of all, register a personal Apple developer account, access Mac App Store, download Xcode, and install the program on your Mac. Apple developer members have access to multiple tools , official iOS development services and features that allow testing apps on your personal device and give the opportunity to launch your application on the App Store itself. Now, let's tdiscuss Apple's tools for iOS developers.
Xcode is an integrated development environment (IDE) and includes development tools for creating iOS and OS X applications. Not just a code editor - it contains many advanced helpful tools such as auto-complete, static analysis, code compilation, repair errors, and performance enhancements before automatic error discovery and memory problems. Xcode instead of a bunch of iOS application development tools: code editor in not required to write the code, and then switch the command line tool to compile, you can Xcode to complete the necessary operations. Xcode is a common tool for development, and contains all the important features.
Interface App Generator
Interface Builder is a useful development application that gives an opportunity to create interfaces directly. All important design elements are accessible - buttons, sliders, navigation bars, icons - all there is to do is drag them into the design and customize their size, color and style. In addition, Interface Builder can help manage interactions within an element, in other words, use it to configure actions that occur when a user interacts with a specific object, and you can define a configuration and binding object.
UI Kit Code and why you have to know it
Although Interface Builder is feature rich, most developers who use custom interface elements like to operate with other programs because creating bespoke objects in iNterface Builder demands a lot of coding. That's the reason why our iOS development specialists recommend that you learn the essentials of the Interface Builder, but also be acquainted with UIKit code it generates. We fully understand that you can ask yourself a question - why learn to write the interface from nothing if you have such a progressive application that will do all things for you. It's just a case of professionalism and experience - grasp the fullest understanding of all the development processes and their interactions to create superior digital products.
iOS Application Development Framework
The framework is probably the most important tool allowing to build and manage iOS apps. Without the framework, it may take years for developers to create simplistic programs that perform on Apple devices. Apple introduces dozens of off-the-shelf solutions that allows to easily troubleshoot information such as user interface code, encrypt sensitive data, write network code, embed media players, draw graphics, take photos, save passwords, view website and other information, etc. Delayed tasks. And so on.
In addition, Apple suggests multiple useful and exciting courses you can use when creating OS X and iOS apps - primarily from other classes and contributing more functionals and features with each fresh link in the inheritance chain. They are in the root class of the NSObject and each of the objects inherits from the previous one.
The structure of Apple is a lot of tools and sets of commands that lay the base for your future apps. If there is no structure, the developer will reinvent each time a new project is started. The Cocoa framework offers many advantages, even if you encounter a very complex problem, you do not know the way to to solve the problem, you are likely to find a solution available there. For example, Cocoa will provide a line of code to do this if you need to get the file automatically through the web address and parse it into a manageable data structure. Cocoa, Interface and Builder Xcode are the main toolkits for all iOS developer, many other useful tools that can be explored. Don't waste precious time - now download Xcode and start playing, discover the basics of iOS development.
When people talk about the development of iOS and OS X, they usually use Cocoa development or C-Objection programming and other terms to express that point, every person with programming experience understands perfectly that they speak of building iOS apps. Cocoa is a UI software building framework on Mac, iPhone, iPad and other devices. These frameworks are largely written in Objective-C, and programmers use this programming language to create Cocoa for iOS and Mac applicationss. During some time, the Cocoa development framework also supports Java, but now no longer requires to access framework. There are multiple ways to reach API: via Perl, C #, Ruby, Python, but they do not receive official support from Apple.
The framework Cocoa consists of app kit - AppKit, and Foundation, where it is possible create apps on OS X, Foundation and UIKit in the case of iOS app development. The base structure consists of several basic class sets, such as array storage, tests and strings, date and time, sorting and filtering, app coordination, and time. The structure includes NSData, NSArray NSString, NSDictionary, NSMutableString and so on. AppKit embeds more than 125 categories to build Mac software interfaces, including buttons, windows, menus, etc. The AppKit objects include NSView, NSApplication, NSCIImageRep, NSWindows, NSView, NSCollectionViewLayoutAttributes, etc.
If you have no experience with Apple app development, please tell us the meaning of the NS prefix. It originated from the multi-tasking object-oriented operating system by NeXT Computer Corporation in 1997 by Apple to purchase, for the established Mac OS X system. Remember that the NS prefix not always indicates an object. Ex: NSRectMake () is a feature that returns the NSRect structure and NSInteger is the raw data type. The NS is not the only prefix utilised in the structure. For example, different structures may include a Core Foundation prefix, UI prefix, MK prefix (MapKit mapping - iOS Framework), CG prefix (Core Graphics) and so on.
Build an app on the iOS system, developers use the same tools developed with Mac OS X available in the Foundation, but using UIKit instead of AppKit when designing the interface. The UIKit object that people use most includes UIActivityViewController, UIWindow, UIView, UIBarItem, UICollectionViewFlowLayout, UIButton, UIColor and UIViewController. Many UIKit objects are similar to the AppKit name, but use another prefix instead of the NS. It is easy to find a complete list of UIKit classes and objects on the Apple development website.
To be honest, there are some objects people will never use, such as airplanes or cars - only if you are creating apps for the transportation and logistics industry or airlines. However, you have to master the objects provided by Apple as part of its structure, and you will often use: NSArray to manage the ordered collection of objects; UITableViewCell defines the properties and behavior of the cells you create; UIViewController to manage your app UILabel displays lines of text or describes the purpose of various controls; UIImageView displays images, and so on.
