Yandex api. Marks for several hours?

Question

iOS

I'm not good at programming, can anyone help me please.
Functional:

• Users see all markers on the map
  
• Each user can post a label
  

Is it possible to implement one common card for all users? i.e. if the user marked a mark on the map, then this mark will be displayed to everyone who looks at the map.
Send links who met with this please

Answer 1

Well, take a Yandex card. Hang a click handler on it, which initiates some kind of prompt-window where the user enters a description of the label. Save lat, lng click location and label description on your server and just take this data and display it when loading the map.
If you need to display the label for n-hours from the moment of publication, then you can simply put this data into the radish and set the expiration date to n hours and they will self-destruct at the right time.
