    use an NSMutableData object and the method -(void)appendData:(NSData *)otherData

    Edited to add example :

    NSMutableData *concatenatedData = [NSMutableData data];
[concatenatedData appendData:iv];
[concatenatedData appendData:salt];
[concatenatedData appendData:encryptedData];
// and now you have all of the data in the single variable "concatenatedData"
