As Steve said the two steps are those, I leave you a bit of code, maybe can help you a bit more:

正如史蒂夫所说的那两个步骤，我给你留下了一些代码，也许可以帮助你一点：

// Don't forget the imports ;)
#import "XMLReader.h"

// You must have a XML string from somewhere
NSString XMLString = yourXML;
// I remove all returns and tabs from the text, after i would be annoying if you don't remove it
XMLString = [XMLString stringByReplacingOccurrencesOfString:@"\r" withString:@""];
XMLString = [XMLString stringByReplacingOccurrencesOfString:@"\t" withString:@""];

// Parse the XML into a dictionary
NSError *parseError = nil;
NSDictionary *xmlDictionary = [XMLReader dictionaryForXMLString:XMLString error:&parseError];

NSError *error;
self.dataParsed = [NSJSONSerialization dataWithJSONObject:xmlDictionary
                                                   options: NSJSONWritingPrettyPrinted // Pass 0 if you don't care about the readability of the generated string
                                                     error:&error];

// Print the dictionary
NSLog(@"%@", xmlDictionary);
