Iphone app development multiple languages

On the Info tab, you will see a section for Localizations. Xcode will list the localizable files in your project and allow you to select which ones it should update. Keep them all selected and click Finish. But wait! Where is Localizable. At this point, Xcode has set up some directories, behind the scenes, to contain localized files for each language you selected. To see this for yourself, open your project folder using Finder, and you should see something similar to the following:. See en.

They contain the language-specific versions of your files. For other languages, see the full list of language codes. So what is Base. Those are the files in the base, or development, language — in this case, English. When your app asks iOS for the localized version of a resource, iOS looks first in the appropriate language directory. Tell Xcode to put it there by selecting it in the Project navigator, then clicking Localize… in the File inspector. Click Localize. The File inspector will update to show the available and selected languages.

Click the checkbox next to Spanish to add a Spanish version of the file. Look at the Project navigator. Select Localizable.

Xcode makes it easy to test your localizations without the bother of constantly changing languages or locales on your simulator. Click the active scheme in the toolbar and choose Edit scheme… from the menu you can also Option-Click on the Run button. Click the Options tab, then change Application Language to Spanish. Click Close. UI elements in your storyboard, such as labels, buttons and images, can be set either in your code or directly in the storyboard. You have already learned how to support multiple languages when setting text programmatically, but the Hello label at the top of the screen has no IBOutlet and only has its text set within Main.

You could add an IBOutlet , connect it to the label in Main. In the Project navigator, open the disclosure triangle next to Main. Click on Main. You should already have an entry for the Hello label which will look something like this:. Xcode lets your preview your storyboard localizations. Select Main. Make sure it is showing the preview of the storyboard:. Since the app uses an image that contains English text, you will need to localize the image itself. Unfortunately, while Apple recommends that you put all of your images into an asset catalog, they provide no direct mechanism for localizing those images.

Not to worry, however, as there is a simple trick that makes it easy to do. Open Assets. Now open Localizable. You use the key imageName to retrieve the name of the localized version of the image and load that image from the asset catalog. You also deleted setting the title of the button from MainViewController.

Build Apps for the World

You have made great progress in preparing your app to run in multiple languages, but there is more to the process than just changing the words. Formatting for other common data, such as numbers and dates, varies around the world. You can expect a minimum of hours of coding time for a simple app, with the average app taking around twice that. Next, think about what your personal goals are for the app. There are no right or wrong answers, but you need to be honest with yourself. Do you aspire to become an app developer , or is this a one-off project?

Do you plan on designing a number of apps over the course of the next few years? Knowing your goals will help you understand the time investment you can put into making the app a reality. Someone has a brilliant idea for an app, and they want to get started immediately by coding it themselves.

After about a week, he or she is overwhelmed with the technology. Many give up, but those who push through spend months rewriting code they hacked out before learning it properly.

Usually, these people either give up entirely or end up outsourcing the project for thousands of dollars. With BuildFire, you can add dozens of different types of functionalities to your app without worrying about bugs in your code or a new software update making everything obsolete.

Imagine you wanted to make a nice pasta for dinner, but instead of buying spaghetti you buy flour, eggs, and a pasta maker. Instead of a jar of sauce, you buy tomatoes and basil.

Internationalizing Your iOS App: Getting Started

You need practice and experience to make something that tastes good. Coding an app is no different. Apple has its own software for building iOS apps called Xcode. It serves as an editor for your code, as well as a debugging tool and way to preview your apps before you launch them. Xcode is free to download, but it only runs on Mac computers. One of the most powerful features of Xcode is the ability to preview your apps through the system. This makes app development challenging because different devices have different screen sizes, resolutions and capabilities.

  • Compounding the problem is the complexity of operating system usage. The most recent data from Apple suggests that about one in nine users is using outdated iOS software. With all this confusion, Xcode makes the process of app testing easier. You can simulate a variety of devices and operating systems to adjust your development accordingly.

    As you design, ensure you use best practices and build an app that works well across different devices. These things may sound trivial, but each element plays a role in whether or not your app is approved by Apple. When it comes down to it, there are really just two languages used for iOS development. The primary languages that dominate are Objective-C and Swift.

    We can connect our UI elements to code through the assistant editor. The assistant editor helps us interact with our storyboard and the ViewController. Next, click on the storyboard so that we can add a new language to the base selection which is the default. Click on the file inspector as shown in the screenshot below and check English:.

    Once you select English , it will generate a file for you. Check the Main. You will notice that it is a folder now with files Main. The Main. Strings file contains the strings extracted from the storyboard. Add the following lines of code to your viewDidLoad method in ViewController. The need for attributed text is to have associated attributes for portions of your text.

    So create a string file to hold the value of our text in the NSLocalizedString macro. Name the file Localizable and put it in the en. You should name the file Localizable. When you click on Create, the file might be hidden. To see the file, right click the ViewController. Open it and add the following code snippet to it.

    We will only be adding text programmatically to the second label. So, click the first label on the storyboard and click on the Connection Inspector as shown below. After deleting as shown below, you can then delete it from your code. Shown below is what we have achieved so far.
