本地语言国际化

这段时间没有那么忙整理了一下关于语言国际化的内容,写在这上面,给没做过的当做资料,也当做是自己的笔记,

首先在工程中创建一个PCH文件,在PCH文件中写入一个宏定义

#define Localized(key)[[NSBundle bundleWithPath:[[NSBundle mainBundle] pathForResource:[NSString stringWithFormat:@"%@",[[NSUserDefaults standardUserDefaults] objectForKey:@"appLanguage"]] ofType:@"lproj"]] localizedStringForKey:(key) value:nil table:@"NSLocalizedLanguage"]

现在为工程建立.string的文件

在这里文件的名字必须要是 NSLocalizedLanguage 因为我的宏定义写的是这个名字

然后在工程中添加需要的语种,更具需要选择

回到工程文件下,点击.string的文件在右侧的设置栏中点击Locallzation 点击语言种类

此时在.string的文件下就会看到选择的语种的文件
在文件中将想要转换的文字,依次写到对应的语言文件里就行了

现在就去工程中添加获取获取系统当前语言的代码来到Application.h
声明选择设置语言界面的控制器 在声明一个方法 如图所示为了写block就写的很简单

接下来在Application.m中添加代码

为了方便我将代码单独放在这里

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {     self.window = [[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];        self.window.backgroundColor = [UIColor whiteColor];    /**     *  获取当前语言     */    if (![[NSUserDefaults standardUserDefaults]objectForKey:@"appLanguage"]) {        NSArray *langusges = [NSLocale preferredLanguages];        NSString *language = [langusges objectAtIndex:0];        if ([language hasPrefix:@"zh-Hans"]) {//开头匹配            [[NSUserDefaults standardUserDefaults] setObject:@"zh-Hans" forKey:@"appLanguage"];        }else{            [[NSUserDefaults standardUserDefaults] setObject:@"en" forKey:@"appLanguage"];        }    }    self.window.rootViewController = [ViewController new];    [self.window makeKeyAndVisible];    return YES;}- (void)ToMain{    self.RootVC = [ViewController new];    self.window.rootViewController = self.RootVC;}

这样获取系统语言就算完成了,viewController.m

#import "ViewController.h"#import "AppDelegate.h"@interface ViewController ()@property (assign ,nonatomic)BOOL IsEngish;@end@implementation ViewController- (void)viewDidLoad {    [super viewDidLoad];    UIButton *LanguageButton = [UIButton buttonWithType:UIButtonTypeSystem];    LanguageButton.frame = CGRectMake(70, 100, 230, 30);    [LanguageButton setTitle:Localized(@"你好") forState:UIControlStateNormal];    LanguageButton.backgroundColor = [UIColor orangeColor];    [self.view addSubview:LanguageButton];    UIButton *English = [UIButton buttonWithType:UIButtonTypeSystem];    English.frame = CGRectMake(70, 160, 60, 30);    [English setTitle:Localized(@"英语") forState:UIControlStateNormal];    English.backgroundColor = [UIColor orangeColor];     [English addTarget:self action:@selector(English:) forControlEvents:UIControlEventTouchDown];    [self.view addSubview:English];    UIButton *Chinese = [UIButton buttonWithType:UIButtonTypeSystem];    Chinese.frame = CGRectMake(240, 160, 60, 30);    [Chinese setTitle:Localized(@"汉语") forState:UIControlStateNormal];    [Chinese addTarget:self action:@selector(chinese:) forControlEvents:UIControlEventTouchDown];    Chinese.backgroundColor = [UIColor redColor];    [self.view addSubview:Chinese];}- (void)chinese:(UIButton *)sender{     [[NSUserDefaults standardUserDefaults] setObject:@"zh-Hans" forKey:@"appLanguage"];    AppDelegate *appDelegate =    (AppDelegate *)[[UIApplication sharedApplication] delegate];    [appDelegate ToMain];}- (void)English:(UIButton *)button{      [[NSUserDefaults standardUserDefaults] setObject:@"en" forKey:@"appLanguage"];    AppDelegate *appDelegate =    (AppDelegate *)[[UIApplication sharedApplication] delegate];    [appDelegate ToMain];}

本地语言国际化大概就是这个流程,在这里我只用了中英文,其他的语言也是一样,
