如何在应用内切换本地化的 Nib? [英] How can you switch localized Nibs within an app?

问题描述

我的要求是从应用程序内切换本地化的 XIB.通常，当您本地化 XIB 并从设置"更改语言时，特定语言的本地化 XIB 会自动加载.

My requirement is to switch localized XIBs from within the app. Usually when you localize a XIB and change the language from Settings, the specific language localized XIB gets loaded automatically.

我有如下图所示的 XIB:

I have XIBs like in the below image:

我想在应用程序中的按钮点击上选择特定语言时加载 XIB.可以在此处找到此类应用程序的源代码.

I want to load the XIB when the specific language is selected on a button tap within an application. Source code for such an application can be found here.

我该怎么做?

推荐答案

我通过创建一个简单的方法解决了这个问题，见下文

I solved the problem by creating a simple method see below

-(void)changeControllersForLanguage:(NSString *)language{

    NSString *path = [[NSBundle mainBundle] pathForResource:language ofType:@"lproj"]; //Detecting specific language lproj folder
    if (path) {
        //Creating Local Bundle from the language specific bundle path
        NSBundle *localeBundle = [NSBundle bundleWithPath:path];

        NSArray *controllers=self.tabBarController.viewControllers;

        for(UIViewController *view in controllers){
            [localeBundle loadNibNamed:NSStringFromClass([view class]) owner:view options:nil];
        }

    }
}

然后在按钮点击时调用如下函数

Then calling the function as below on button tap

- (IBAction)toggleLanguage:(id)sender {
    UIButton *btn=(UIButton *)sender;

    switch (btn.tag) {
        case 1://French
            [self changeControllersForLanguage:@"fr"];
            break;
        case 2://English
            [self changeControllersForLanguage:@"en"];
            break;

        default:
            break;
    }
}

它真的有效.. :)
