AVSubclassing Protocol Reference
| Declared in | AVSubclassing.h |
|---|
Overview
If a subclass of AVObject conforms to AVSubclassing and calls registerSubclass, LeanCloud will be able to use that class as the native class for a LeanCloud object.
Classes conforming to this protocol should subclass AVObject and include AVObject+Subclass.h in their implementation file. This ensures the methods in the Subclass category of AVObject are exposed in its subclasses only.
+ parseClassName
The name of the class as seen in the REST API.
+ (NSString *)parseClassNameDiscussion
The name of the class as seen in the REST API.

+ objectWithoutDataWithObjectId:
Creates a reference to an existing AVObject for use in creating associations between AVObjects. Calling isDataAvailable on this object will return NO until fetchIfNeeded or refresh has been called. No network request will be made. A default implementation is provided by AVObject which should always be sufficient.
+ (instancetype)objectWithoutDataWithObjectId:(NSString *)objectIdParameters
