The inner dictionary contains your actual data, with keys NodeContent and NodeName. I’m guessing you want to traverse all the innermost dictionaries, looking for entires with a nodeName value of “MyID”, and … Read more

Another hint of advice for you, best practice in Objective-C is that variables should always start with lower case letters. Change “ObjIstructContacts“, “Qnarray” and “Qnstream” to start with lower case … Read more
