IOS Localization Application

IOS Localization Application

The BK project has been completed in. Later versions of the project need to be translated into multi-language versions to adapt to the use of multiple stores in multiple countries around the world.

Application localization is to localize strings, images, and xib or storyboard files respectively. The traditional approach is to associate a variable with strings on xib (including UILabel, UIButton, UITextField, and so on ).NSLocalizedStringThis function is used to find Localizeable. the key value in the strings file is localized, or different language versions of the same xib file are generated, such as MainVC. xib (German) and MainVC. xib (English), but it is too complicated to do so, as people often say tedious and useless.

Let's first introduce the general process of Localization:

(1) pseudo-localizationPseudo-localization is the process of localized strings into meaningless languages. To replace the string to be translated with another assumption that it is already a translated "Translation", you can use Google Translate to replace it or replace all vowels with x, for example: press here to continue to Prxss hxrx tx cxntxnxx ". This aims to detect problems as soon as possible. <喎?http: www.bkjia.com kf ware vc " target="_blank" class="keylink"> VcD4KPHA + primary + 9rbFvvi74dOwz + yxvrXYu6 + primary/r/primary + t6K4 + Let0uvIy9Sxu/LV38rHsb612Luvt/primary = "http://www.2cto.com/uploadfile/Collfiles/20140718/2014071809451874.png" alt = "\">

(3) LocalizationAfter resources are sent to the localization service provider, they will send back the translated files. Perform Localization Based on the translated text.

(4) Version ControlUse the version control system to record each of your changes.

(5) testThe required steps.

(6a) Merge logical changesLogical changes generally do not affect the work of nib files and localization. projects that involve multi-person collaboration still need to merge the logic of some changes.

(6b) localization changeIf you have made some localization changes, such as changing the localized text, you need to start the process from scratch and send these changes to the localization personnel. It can reuse the previous string translation, which will greatly improve the efficiency, but it is still very troublesome. Therefore, we should try to avoid introducing such changes later in development.

I have already written many articles about application localization before. I will not repeat them here. I will directly post the articles I have read that are not bad:

1. MJ's application localization, written in 2013. For XCode5, some operation interfaces are different, but the idea remains unchanged.

2. IOS app internationalization tutorial (version 2014), which is relatively new and uses storyboard.

3. Internationalization Tutorial for iOS [2014 Edition] On RAYWENDERLICH all of the above articles are good and worth reading. It is strongly recommended.

In addition, the focus is on a Class I found on github, which is very good. The elegant code has been touched by my tears ~~

This is the project address on github: HERE. If you find more and better code, please let me know.

As the author said:

Below isOHAutoNIBi18n. mClass. without changing the frame, the font size of UILabel, UIButton, and UITextField is adaptive.

Tips:Also required for localizationNote:
    
1. Do not forget to read the language from the right to the left.
    
2. Do not simply assume that the comma is a thousands separator and the period is the decimal point. It may be different in different languages.
    
3. Note the formatting of numbers and dates (both input and output must be formatted ).
    
Now, the application localization is much simpler, and the rest will be handed over to the translators ~
