xamarin - How to await iOS openURL overridden method? -


i have share feature in mail application can open application clicking share button. able open app when user click share mail app, issue openurl method.

below openurl method:

public override bool openurl(uiapplication application, nsurl url, string sourceapplication, nsobject annotation) {     upload(url);     return true; }  async public task<bool> upload(nsurl shareduri) {   //upload  }

problem above code since upload function not awaited, before upload function finishes app opened.

how can await task in openurl?

you have many options here, 1 of returning upload's result. remember await time consuming task inside of upload.

public override bool openurl(uiapplication application, nsurl url, string sourceapplication, nsobject annotation) {         return this.upload(url).result; }  async public task<bool> upload(nsurl shareduri) {       await someuploadtask();       return true; }

i agree sunil should show indication of action user, here's control should use: https://developer.xamarin.com/api/type/xamarin.forms.activityindicator/

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...
