如何在运行时更改 iPhone 应用程序语言? [英] How to change iPhone app language during runtime?

问题描述

有没有办法在运行时更改应用程序语言?

Is there a way to change the application language during runtime?

因此，更改后 NSLocalizedString 立即返回新语言的字符串.

So, after the change NSLocalizedString immediately returns the string for the new language.

我现在正在做的是使用以下代码更改语言:

What I'm doing now is changing the language using the code below:

- (void)onChangeLanguage: (id)sender 
{
    NSArray *lang = [NSArray arrayWithObjects:((InfoWhatever *)sender).language, nil];
    [[NSUserDefaults standardUserDefaults] setObject:lang forKey:@"AppleLanguages"];
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    NSArray *languages = [defaults objectForKey:@"AppleLanguages"];
    NSString *currentLanguage = [languages objectAtIndex:0];

    NSLog(@"Current language: %@", currentLanguage);
}

语言会改变，但只有在重新启动后应用程序.

The language will change but only after restarting the app.

推荐答案

我怀疑你能做到这一点，即使设置应用程序也做不到.

I doubt you can do this, even the Settings app cannot do it.

(当你在设置应用中更改语言时，屏幕变黑，并显示设置语言..."和一个进度轮.经过漫长的等待，你回到了 Springboard.它几乎看起来像手机重新启动.)

(When you change the language in the Settings app, the screen goes black, and displays "setting language..." and a progress wheel. After a long wait, you are back in Springboard. It almost looks like the phone reboots.)
