ios 应用多语言自由切换实现

第一次进入应用获取本机语言.1.假设本机语言在软件实现语言列表里.则默认选中本机语言，可是用户还是能够选择其他语言.2.假设本机语言不在软件实现语言列表里,则默认选中英语.用户还是能够选择其他语言.

全部要更换语言的controller里注冊通知.当用户选择了一个语言后发送语言改动的通知.控制器收到语言改动通知后，对须要改动语言的控制进行又一次设置.

/** 初始化语言 */

- (void)initLanguage{

//1.
获取系统支持的语言

_languages = [NSMutableArrayarrayWithCapacity:5];

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

NSDictionary *dic = [NSDictionarydictionaryWithContentsOfURL:url];

//2
生成语言对象

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

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

[_languagesaddObject:language];

}];

//3.
获取用户保存的语言[0] = 中文简体, [1] = zh-Hans;

NSString *userLanguageValue = [selfgetUserLanguage];

if (!userLanguageValue) {

userLanguageValue =kDefaultUserLanguage;

//3.1
获取系统语言

NSString * localLanguage = [selfgetLocalLanguageValue];

//3.2.
确定默认语言

for (DYCXLanguage *languagein_languages)
{

//3.3.假设软件语言包涵系统语言默觉得系统语言,假设不包涵默认设置为英语

if ([localLanguageisEqualToString:language.languageValue]) {

userLanguageValue = localLanguage;

}

}

}

//4.
设置当前语言

for (DYCXLanguage *languagein_languages)
{

if ([userLanguageValueisEqualToString:language.languageValue]) {

language.used =YES;

_userLanguage = language;

break;

}

}

}

- (NSString *)getLocalLanguageValue{

NSUserDefaults *defaults = [NSUserDefaultsstandardUserDefaults];

NSArray *languages = [defaultsobjectForKey:@"AppleLanguages"];

return [languagesobjectAtIndex:0];

}

#pragma mark - 语言更改,又一次载入

- (void)reloadStringWithLanguage{

[_confirmsetTitle:[NSStringlocalizedWithString:@"dialog_positive_key"]forState:UIControlStateNormal];

_selectLanguage.text = [NSStringlocalizedWithString:@"select_language_key"];

if ([self.delegaterespondsToSelector:@selector(onLanguageChange)])
{

[self.delegateonLanguageChange];

}

}

#pragma mark -NSString 的分类,载入相应文件夹里的string

+ (NSString *)localizedWithString:(NSString *)key{

NSString *area = [DYCXConfigsharedDYCXConfig].userLanguage.languageValue;

if (!area) {

area = kDefaultUserLanguage;

}

NSString *table = [NSStringstringWithFormat:@"%@.lproj/Localizable",
area];

NSString *localizedString = [[NSBundlemainBundle]
localizedStringForKey:(key)value:nil
table:(table)];

NSAssert(localizedString,@"localized error, table = %@, key = %@", table, key);

return localizedString;

}

以本地化方式获取国际化信息的显示名称

NSLocale *curLocal = [[NSLocale alloc]initWithLocaleIdentifier:@"zh-Hans"] ;

NSLog(@"%@",[curLocal displayNameForKey:NSLocaleIdentifier value:@"fr_FR"] );// 法文（法国）

curLocal = [[NSLocale alloc]initWithLocaleIdentifier:@"zh-Hant"] ;

NSLog(@"%@",[curLocal displayNameForKey:NSLocaleIdentifier value:@"fr_FR"] );//法文（法國）
