Hi, I have a NsMutableArray, at each index there are several keys like:

Arrat🙁
{
id=0;
img="xxx";
act="xxx";
},
{
...
}

...
)

I would like to replace the value for a determinate key of my array in an index. In documentation I see:

- (void)replaceObjectAtIndex🙁NSUInteger)index withObject🙁id)anObject

It would be easy if my array was only index no keys, but with several keys... Any Idea?

NSMutableDictionary is what you want.

Yes, its an array of NsMutableDictionarys, but how can I to replace? Have I to create a new nsmutabledictionary, to remove the index in array and to add the new NsMutableDictionary to this index? Only I want to replace a key for an index of array.

If you only want to change one key at one index you could do

[[myArray objectAtIndex:i] setObject:newObject forKey:key]
