ios 應用多語言自由切換實現

第一次進入應用擷取母語.1.如果母語在軟體實現語言列表裡.則預設選中母語，但是使用者還是可以選擇其它語言.2.如果母語不在軟體實現語言列表裡,則預設選中英語.使用者還是可以選擇其它語言.

所有要更換語言的controller裡註冊通知.當使用者選擇了一個語言後發送語言修改的通知.控制器收到語言修改通知後，對需要修改語言的控制進行重新設定.

/** 初始化語言 */

- (void)initLanguage{

//1. 擷取系統支援的語言

_languages = [NSMutableArrayarrayWithCapacity:5];

NSURL *url = [[NSBundlemainBundle]URLForResource:kLanguagePlistwithExtension:kTypePlist];

NSDictionary *dic = [NSDictionarydictionaryWithContentsOfURL:url];

//2 產生語言對象

[dicenumerateKeysAndObjectsUsingBlock:^(id key,id obj,BOOL *stop) {

DYCXLanguage *language = [DYCXLanguagelanguageWithKey:keyAndValue:obj];

[_languagesaddObject:language];

}];

//3. 擷取使用者儲存的語言[0] = 簡體中文, [1] = zh-Hans;

NSString *userLanguageValue = [selfgetUserLanguage];

if (!userLanguageValue) {

userLanguageValue =kDefaultUserLanguage;

//3.1 擷取系統語言

NSString * localLanguage = [selfgetLocalLanguageValue];

//3.2. 確定預設語言

for (DYCXLanguage *languagein_languages) {

//3.3.如果軟體語言套件涵系統語言預設為系統語言,如果不包涵預設設定為英語

if ([localLanguageisEqualToString:language.languageValue]) {

userLanguageValue = localLanguage;

}

}

}

//4. 設定當前語言

for (DYCXLanguage *languagein_languages) {

if ([userLanguageValueisEqualToString:language.languageValue]) {

language.used =YES;

_userLanguage = language;
