iOS Question How can I modify a Value of a Map

You do not show your entire code but it should be the immutable "bug" of maps in B4i (maybe objective C feature) which the only way to face it is to recreate the map. Copy all keys with values to a new map and set this to the given map. You can do this with a function where you send as argument your map and what the function returns you set it to the same map. Of course you will create the function which will return a map. This happens when you recreate map or list of maps from a JSON.

B4X:

Public Sub TestMap

    'Update
'    map1.Remove("vchUUID")
    map1.Put("vchUUID", "Update")
    Log(map1.As(JSON).ToString)
   
End Sub

No I want to modify a map set before and after update only one a value of this same map, but not refresh


I Tried this:


'Update

map1.Put("vchUUID", "Update")
Log(map1.As(JSON).ToString)

I had to create a new one map as told hatzisn
