🌏 iOS localization/Internationalization and in-app switching language example.

Localization/Internationalization

In-app switching language

In this example, In-app switching language typically has the following steps:

Key code

JYLanguageViewController.m

// Set new language
[[NSBundle localizedBundle] setUserLanguage:key];
// send reload root viewController notification
[[NSNotificationCenter defaultCenter] postNotificationName:@"kNotifyRootViewControllerReset" object:nil];

NSBundle+JYLocalized.m

- (void)setUserLanguage:(NSString *)language {
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    NSString *path = [[NSBundle mainBundle] pathForResource:language ofType:@"lproj"];
    // construct a new bundle
    [NSBundle setLocalizedBundle:[NSBundle bundleWithPath:path]];
    // Store new language tags locally
    [defaults setObject:language forKey:kUserLanguage];
    [defaults synchronize];
}

AppDelegate.m

- (void)resetRootViewController {
    // Add animations
    @weakify(self);
    [[JYTabBarManager manager] resetTabBarController];
    [UIView transitionWithView:self.window
                      duration:0.3
                       options:UIViewAnimationOptionTransitionCrossDissolve
                    animations:^{
                        @strongify(self);
                        // Switch the RootViewController to reload all viewController
                        [self.window setRootViewController:nil];
                        [self.window setRootViewController:[JYTabBarManager manager].tabBarController];
                        [[JYTabBarManager manager] tabBarController].selectedIndex = 0;
                        [self.window makeKeyAndVisible];
                    } completion:nil];
}

中文介绍

🌏 iOS本地化/国际化与应用内切换语言的一个范例。

本地化/国际化

应用内切换语言

在该示例中，应用中切换语言一般会经历以下几个步骤：

关键代码

JYLanguageViewController.m

// 设置新的语言标示
[[NSBundle localizedBundle] setUserLanguage:key];
// 发送重新加载root viewController通知
[[NSNotificationCenter defaultCenter] postNotificationName:@"kNotifyRootViewControllerReset" object:nil];

NSBundle+JYLocalized.m

- (void)setUserLanguage:(NSString *)language {
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    NSString *path = [[NSBundle mainBundle] pathForResource:language ofType:@"lproj"];
    // 构造新的bundle
    [NSBundle setLocalizedBundle:[NSBundle bundleWithPath:path]];
    // 将新的语言标示存入本地
    [defaults setObject:language forKey:kUserLanguage];
    [defaults synchronize];
}

AppDelegate.m

- (void)resetRootViewController {
    // 添加动画
    @weakify(self);
    [[JYTabBarManager manager] resetTabBarController];
    [UIView transitionWithView:self.window
                      duration:0.3
                       options:UIViewAnimationOptionTransitionCrossDissolve
                    animations:^{
                        @strongify(self);
                         // 切换RootViewController使得构建在它上面的ViewController都重新加载
                        [self.window setRootViewController:nil];
                        [self.window setRootViewController:[JYTabBarManager manager].tabBarController];
                        [[JYTabBarManager manager] tabBarController].selectedIndex = 0;
                        [self.window makeKeyAndVisible];
                    } completion:nil];
}
