NSString *account = NSLocalizedStringFromTableInBundle(Account_Lb_Title, nil, [[LanguageTool getInstance] getLocaleBundle] , @"");
这样就能显示实时切换语言,不用退出app
这里是tableview的点击事件,点击切换语言
if(row == 0){
[self changeLanguage:@"en" BeforeCell:temp AfterCell:indexPath];
// [self changeLanguage:@"en"];
// [self changeLanguage:@"en" BeforeCell:_selectRow AfterCell:row]
}else if(row == 1){
[self changeLanguage:@"zh-Hant" BeforeCell:temp AfterCell:indexPath];
// [self changeLanguage:@"zh-Hant"];
}
swift:
原理一样,可以引用上面的Util
调用:
let menuPingTest = NSLocalizedString(Config.advanced.menu_ping_test, tableName: nil, bundle: (LanguageTool.getInstance()?.getLocaleBundle())! ,value: "", comment: "")
还有其他针对swift的切换办法,参考如下:
