首先怎么创建多语言就不说了 创建多个语言文件 根据key找到对应的value以对应不同的语言。
说一下怎么在应用中设置
首先创建一个工具类 用于管理应用中的语言
在单例方法中
+(instancetype)sharedTool{
staticdispatch_once_tonceToken;
dispatch_once(&onceToken, ^{
sharedTool= [[FBLanguageToolalloc]init];
NSArray*array = [selfgetFontsArray];
sharedTool.fontsArray= array;
NSUserDefaults*def = [NSUserDefaultsstandardUserDefaults];
NSString*string = [defvalueForKey:userLanguage];
if(string.length==0){
//获取系统当前语言版本(中文zh-Hans,英文en)
NSArray* languages = [defobjectForKey:@"AppleLanguages"];
NSString*current = [languagesobjectAtIndex:0];
sharedTool.current= current;
//确定是否能在预置的语言中找到本机的语言如未找到则用默认语言
if(![selfcanChangeCurrent:current]) {
//设置默认语言是英语
sharedTool.current=@"en";
}
string =sharedTool.current;
[defsetValue:currentforKey:userLanguage];
[defsynchronize];
}
//获取文件路径
NSString*path = [[NSBundlemainBundle]pathForResource:stringofType:@"lproj"];
sharedTool.bundle= [NSBundlebundleWithPath:path];//生成bundle
});
returnsharedTool;
}
其中getFontsArray方法用于获取预置的几种语言
+(NSArray*)getFontsArray{
FBLanguageObject*zhhans = [[FBLanguageObjectalloc]initWithTitle:@"简体中文"language:@"zh-Hans"];
FBLanguageObject*en = [[FBLanguageObjectalloc]initWithTitle:@"english"language:@"en"];
FBLanguageObject*ko = [[FBLanguageObjectalloc]initWithTitle:@"한국어"language:@"ko"];
FBLanguageObject*idl = [[FBLanguageObjectalloc]initWithTitle:@"Indonesia"language:@"la"];
FBLanguageObject*jan = [[FBLanguageObjectalloc]initWithTitle:@"日本語"language:@"ja"];
FBLanguageObject*th = [[FBLanguageObjectalloc]initWithTitle:@"ภาษาไทย"language:@"th"];
FBLanguageObject*ru = [[FBLanguageObjectalloc]initWithTitle:@"русский"language:@"ru"];
NSArray*array = [NSArrayarrayWithObjects:zhhans,en,jan,idl,ko,th,ru,nil];
returnarray;
}
canChangeCurrent用于判断当前机器所在环境是否包含在预置的语言中，如果不存在则选择默认语言。
+(BOOL)canChangeCurrent:(NSString*)current{
for(FBLanguageObject*objectinsharedTool.fontsArray) {
if([currenthasPrefix:object.language]) {
sharedTool.current= object.language;
returnYES;
}
}
returnNO;
}
languageWithLocalTitle用于通过key查找对应环境下的value
-(NSString*)languageWithLocalTitle:(NSString*)localTitle{
return[self.bundlelocalizedStringForKey:localTitlevalue:niltable:@"hello"];
}
在应用中设置语言 通过setUserLanguage进行修改。
-(void)setUserLanguage:(NSString*)language{
NSUserDefaults*def = [NSUserDefaultsstandardUserDefaults];
//1.第一步改变bundle的值
NSString*path = [[NSBundlemainBundle]pathForResource:languageofType:@"lproj"];
self.bundle= [NSBundlebundleWithPath:path];
//2.持久化
[defsetValue:languageforKey:userLanguage];
//3.同步
[defsynchronize];
[[NSNotificationCenterdefaultCenter]postNotificationName:languageDidChangeobject:nil];
}
到这里 工具类就写好了
在相应的需要变换文字的控件中添加消息的监听
-(instancetype)initWithFrame:(CGRect)frame{
self= [superinitWithFrame:frame];
if(self) {
[[NSNotificationCenterdefaultCenter]addObserver:selfselector:@selector(changeTitle)name:languageDidChangeobject:nil];
}
returnself;
}
-(void)changeTitle{
[selfsetTitle:[[FBLanguageToolsharedTool]languageWithLocalTitle:_localTitle]forState:UIControlStateNormal];
}
-(void)setLocalTitle:(NSString*)localTitle{
_localTitle= localTitle;
[selfchangeTitle];
}
-(void)dealloc{
[[NSNotificationCenterdefaultCenter]removeObserver:self];
}
