1. 多語言切換範例程式碼
GitHub:
https://github.com/f40706/change_language_1/tree/main
2. 範例程式碼結果圖
範例程式碼中英文翻譯表
英文
“PressedEnglish" = “Pressed English";
“PressedChinese" = “Pressed Chinese";
中文
“PressedEnglish" = “點擊英文";
“PressedChinese" = “點擊中文";
2. 新增多語言方法
實際功能，可以下載GitHub範例
這樣就新增完成囉
3. 程式碼
核心程式碼
-(void) initLanguage: (NSString*) selectLanguage {
NSString *localeLanguageCode = [[[NSBundle mainBundle] preferredLocalizations] firstObject];
NSLog(@"localeLanguageCode-> %@",localeLanguageCode);
if([selectLanguage isEqual: @"en"]) {
NSString *path = [[NSBundle mainBundle]pathForResource:@"en" ofType:@"lproj"];
bundle_language = [NSBundle bundleWithPath:path];
} else if([selectLanguage isEqual: @"zh"]) {
NSString *path = [[NSBundle mainBundle]pathForResource:@"zh-Hant" ofType:@"lproj"];
bundle_language = [NSBundle bundleWithPath:path];
}
}
-(NSString*) getStringForKey:(NSString*)key withTable:(NSString*)table {
NSString *string = @"";
if(bundle_language) {
string = NSLocalizedStringFromTableInBundle(key, table, bundle_language, @"");
return string;
}
string = NSLocalizedStringFromTable(key, table, @"");
return string;
}
