xcode - How to find iOS locale hierarchy -


the ios system automatically picks suitable available localization app. instance, when user's locale en-in app offers en-gb, that'll act fallback (as explained here).

my question is: possible these hierarchies somewhere?

the reasoning behind question that, instance, may have translations in es-co, es-cl, es-pe, ... identical , instead of including separate string files of them, i'd provide them 1 common fallback locale. know use es-419 in exemplary case might not obvious in other scenarios.

answering myself here:

bundle.preferredlocalizations(     from: ["es", "es-419", "es-ar", "es-cl", "es-co", "es-mx", "es-pe"],     forpreferences: ["es-pe"])

returns ["es-pe", "es-419", "es"] means peruvian spanish fill fall es-419 , es in order.

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
