How to use XML to Objective-C
- Paste a representative XML sample, ideally one with all the optional fields filled in.
- Set the name of the root type, and decide whether you want helper code as well or types only.
- Copy the generated Objective-C code into your project.
About XML to Objective-C
Writing model classes by hand for a big XML payload is dull, and it is where typos creep in. Paste a sample here and the generator works out the structure: which fields exist, which are objects, which are arrays and what type each value has. The output is NSObject subclasses with a QT prefix and JSON conversion helpers built on NSJSONSerialization.
XML is first converted to JSON the same way as in our XML to JSON tool: attributes get an @_ prefix and text content next to attributes is called #text. The Objective-C types are generated from that result. The header and the implementation are generated together, copy them into a .h and a .m file.
Using the generated code
Use the generated +fromJSON:encoding:error: method to turn a JSON string into an object, and -JSON to go back.
Optional values are plain object pointers that may be nil, numbers are wrapped in NSNumber.
