The app references non-public selectors in Payload/<Appname>.app/<App name>: decoder

I am getting this warning while submitting app to the Apps store through organizer.

> The app references non-public selectors in Payload/.app/ name>: decoder

i know we get this warning if we use any Third Party API in our application. I have used SOCKETIO-ObjC library for chat functionality in application. Also used facebook iOS sdk for fb implementation.So i am not getting exactly what causes this warning.! Please find attached ScreenShot for better understanding

You may get this warning just for using a selector in your own code or third party code that has the same name as some selector that is marked as non-public. Happens to me all the time. Never got rejected for it.

By "same name" i mean just something as simple as you having an object with this selector:

-(id) XYZKMyClass doSomethingFancy:(id) toThis

...and there being a selector like this for an internal Apple functionality

-(id) ApplesClass  doSomethingFancy:(id) toSomething

So: What it seems they are looking for is the signature -(id) doSomethingFancy:(id). You can see how it's very easy to accidentally bump up against this.

Presumably they perform a deeper check at the App Store Police HQ, and determine that the flagged selector is in your code, and hence OK.

This can help you:

Before:

#import "SocketIOJSONSerialization.h"

extern NSString * const SocketIOException;

// covers the methods in SBJson and JSONKit
@interface NSObject (SocketIOJSONSerialization)

// used by both JSONKit and SBJson
- (id) objectWithData:(NSData *)data;

// Use by JSONKit serialization
- (NSString *) JSONString;
**- (id) decoder;**

// Used by SBJsonWriter
- (NSString *) stringWithObject:(id)object;

@end

After:

#import "SocketIOJSONSerialization.h"

extern NSString * const SocketIOException;

// covers the methods in SBJson and JSONKit
@interface NSObject (SocketIOJSONSerialization)

// used by both JSONKit and SBJson
- (id) objectWithData:(NSData *)data;

// Use by JSONKit serialization
- (NSString *) JSONString;
**- (id) jsonDecoder;**

// Used by SBJsonWriter
- (NSString *) stringWithObject:(id)object;

@end
