inputStreamWithData:
Creates and returns an initialized
NSInputStream object for reading from a given NSData object.
+ (id)inputStreamWithData:(NSData *)data
Parameters
- data
- The data object from which to read. The contents of data are copied.
Return Value( NSInputStream inputStreamWithData example )
An initialized
NSInputStream object for reading from data. If data is not an NSData object, this method returns nil.

NSInputStream *dataStream = [NSInputStream inputStreamWithData:[soapBody dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBodyStream:dataStream];
