Today, the IT sector is developing quite rapidly. Each person, if he wants to try himself in it, chooses one of the directions and moves towards the goal. Many people prefer developing mobile applications for iOS and Android. To create them, of course, is quite difficult; patience, knowledge and free time are necessary. If you are serious about it, then you should study and go to your goal. How to create an application for iOS yourself?
Development environment
First you need to install a program where you will work with the interface and prescribe actions for the necessary elements. The most common is Xcode. Unfortunately, this development environment is available only to users of Apple products. To date, there is no official version for Windows or Linux. A different version of iOS requires a different version of this program.
Graphics Add-ons
To develop an image or design for games, you must install a utility for working with graphics. A common application is CorelDraw, which allows you to create photos using vector graphics. Of course, for full work you need to purchase the full version, but you can use standard methods for free.
Objective-c
The Objective-C programming language is used to create functionality for the game. As you can see, he went from the C language family, so if you have studied another programming language before, you can spend quite a bit of time on in-depth study and start creating your own applications. Of course, there are many books on learning Objective-C.
Account creation
In order to subsequently sell your application, you need to register in the AppStore. In it, you can also provide other users with open access so that they can test the program. Of course, it is not free. You will need $ 100 to put your application on sale for one year.
You can also see test applications in your App Store account . Some provide information on how they were developed. Look at similar examples with what you want to create and try to do something similar.
App layout
First you need to decide on the target audience for your application. The interface and functionality will depend on this. Of course, if you are developing a program, then you should achieve a solution that was not there before. This is the only way to achieve popularity.
It is also worth deciding on how the application will be arranged. You should make the interface as simple as possible so that it attracts new people, and not scare you without showing your capabilities.
Each button should display its actions and show what it will do. The user should not have questions about what any key will do. Think, and then bring to life, a high-quality interface.
Application creation
First you need to open the development environment in question and create a new project. To do this, go to the "File" section and go to the "Application" item. Next, select "iOS" and go to the empty application "Empty Application".
You can create an application for iOS using various templates that are created for different tasks. To begin with, it is better to use empty to deal with all the subtleties. You can apply them later.
In the new window, enter the product name and your identifier, you should also specify the class prefix. If you are a novice developer, you should indicate “com.example” in the identifier field and “XYZ” in the prefix field. Next, select “iPhone” from the proposed devices and confirm your actions.
Use storyboard
You can use Storyboard at the beginning of the journey to create an iOS app. What it is? This is a function that allows you to visually present all your screens in the program. It shows all the windows and transitions that are used between them. This is a good helper in creating a program. To open Storyboard you must:
go to the "File" section and the "New" item;
select the “File” button and go to the “User Interface”;
after that we select the necessary function;
it remains only to select the "iPhone" device and name the file.
It should be remembered that it must be saved in the folder where data about your project is stored.
Add a screen
To add a screen, you must use a view controller. It allows you to determine what the user interface will look like. There are many built-in view controllers. You can look at each available option and decide which design you like best.
· To do this, go to the file "Main.storyboard" through the navigation.
· Select “Object Library” to load all the necessary objects.
· You need to click on “View Controller” and drag it to your project. So you add your first screen.
The objects
How to create a mobile application for iOS? So, you have decided on the interface and added a screen, now you can proceed to the creation of certain objects. To use standard items, open the Objects Library list. If you find a suitable object, then you can transfer it to your screen. It can be easily moved and scaled.
Editing Elements
By placing objects, you use a kind of constructor. It’s possible to create an iOS application, but these elements have an ugly, standard look. To change the design: color, font, add pictures and other parameters, you need to select an object and go to its properties. You can do this by clicking on the “Attributes Inspector” button (the label resembles a shield).
Navigation bar
Soon you will add many other screens, and the program will require you to enter navigation so that you can easily find the information you need. To add it, you must:
Find the place where this element will be located. It is best applied to the home screen to control other windows.
Click on the “Editor” button and go to the “Embed In” item.
It remains only to select the necessary element - "Navigation Controller".
Additional features
As you may have noticed, we have not yet used a programming language to create an application for iOS. This moment will be only on you. You should think up what your application should execute and drink actions in Objective-C language under it. If you do not have good programming skills, then you should read additional literature.
Application testing
Xcode has an emulator that allows you to test. After creating the application for iOS, you need to test it, check the operability. To do this, go to the "Simulator and Debug" section. We select the device with which you want to test.
Program assembly
How to create an application for iOS yourself? To fully test a program or game, you must assemble a project. Go to the “Build” item and click on it. So you compile the application, and after that it will start immediately. It will take you about five minutes. You will be able to observe how the assembly will take place.
Device for checking
To finally make sure that your project is working, you need to perform testing on your device. If you have an iPhone, then you can do it without problems. We connect our device to the PC. Then we carry out the actions that we have already considered. Click on the "Device and Debug" button, and then go to the "Build" item. After a few minutes, when the application is assembled, it will start on your device.
If you figured out how to create an application for Android and iOS, but you have some problems, you need to fix them. You can see in the console what errors occurred during testing. In general, this is a fairly important process, because if you test your application well, it will bring success. You can also take the help of your friends. To do this, send them your application and wait until they find an error.
Project Publishing
You need to create an assembly. To do this, select the "Distribution" item in the menu and click on the "Build" button. Next, select your project and archive it. You must understand that the application must be optimized for the necessary platform and be suitable for the retina display, without which it will not be approved.
Go to the account in the AppStore and add a new program or game. You will need to enter all the information about the application: name, description, keywords, category, copyrights and contacts. We also fill in the field with price and rights. It remains only to add an icon to your application and a few screenshots.
Check
After downloading your application, it will be checked. After a few days you should be given an answer. At the initial stage, the program is automatically checked. If everything went well, then it is transferred to the “In review” state. If this does not happen, then in a few hours you will be able to receive an answer to the mail. You can also get information on how defects can be fixed and what is needed for this.
If the application has passed all the checks, then it will be placed on the Apple Store for sale. Your task now is to advertise a program or game. How much money you make will depend on this. You can apply various services for advertising.
Conclusion
Application development is done in a similar way, but in a different development environment for Windows. How to create an application for iOS? This is a rather long and complicated process. This must be approached with certain knowledge and skills. Only in this way can you achieve anything. You can realize your ideas without certain skills. Choose the right company and consider how much it costs to create an application for iOS. You can also order some components if you are unable to do something yourself.
