Converting NSDecimalNumber to NSString

Question

I'm retrieving a key from an object that looks like this:

po obj
{
  TypeID = 3;
  TypeName = Asset;
}

The key value is being retrieved like this:

NSString *typeId = (NSString*)[obj objectForKey:@"TypeID"];

Rather than typeId being an NSString, it is an NSDecimalNumber. Why is that?

How do I convert it to an NSString?

Answer 1

You need to use the stringWithFormat function:

NSString *typeId = [NSString stringWithFormat:@"%@", [obj objectForKey:@"TypeID"]];

or stringValue:

NSString *typeId = [[obj objectForKey:@"TypeID"] stringValue];
