iOS Question iOS Map Collections (Read Only)

[fbritop]

Erel,
Is it possible in B4I to attach an imageview to a map key?

I have done it in Android but in iOS there is no chance to retrieve this image after from the map.

Is there any special treament to attach an imageview to a map?. Same thing happends when I put a label. After putting any of these items, if I log the map it outputs only numeric or string values:

(read only map) {
    idProducto = 1302;
    isActive = 1;
    isDelete = 0;
    isDiferido = 0;
    isNew = 0;
    isOffer = 0;
    precio = 36900;
    precioFormat = "$ 36.900";
    producto = "Nutra Nuggets Large Breed Puppy";
    unidad = "SACO 15 KG";
}

Erel,
I figured out what happens with this problem.

It seems than in B4I, when a map comes from a JSON Object it turns out automatically to a Read Only Map:

JSON:
{"favoritos":[{"item1", "item2", "item3"}]}

.....

Dim map1 As Map = JSONP.NextObject
favoritos = map1.get("favoritos")
Dim m as Map
For i = 0 To favoritos.Size - 1
    m = favoritos.Get(i)
    log(m)
next

This code execution, in the log will bring a (read only map), which I cannot "PUT" any other item into it. This disables any chance that from a CustomListView to retrieve any object that’s inside (which is an excellent method to reference any views created dynamically).

After some tests, I did a small function to transform a Read Only Map to an NSMapTable

Sub map2Map(m As Map) As Map
    Dim m2 As Map
    m2.Initialize
    For Each key As String In m.keys
        m2.put(key,m.Get(key))
    Next
    Return m2
End Sub

Dim mProcess as Map=map2Map(m)
log(mProcess)

Now if we log the mProcess Map after passing it through map2map function, now it contains a writeable Map

Hope it helps any lost souls with this same trouble.
