To all,
I was looking at the sample project from http://iphoneonrails.com/ and I saw they took the NSObject class and added methods to it for the SOAP calls.
Their sample project can be downloaded from here http://iphoneonrails.com/downloads/objective_resource-1.01.zip.
My question is related to my lack of knowledge on the following syntax as I haven't seen it yet in a iPhone project.
There is a header file called NSObject+ObjectiveResource.h where they declare and change NSObject to have extra methods for this project. Is the "+ObjectiveResource.h" in the name there a special syntax or is that just the naming convention of the developers.
Finally inside the class NSObject we have the following
#import <Foundation/Foundation.h>
@interface NSObject (ObjectiveResource)
// Response Formats
typedef enum {
XmlResponse = 0,
JSONResponse,
} ORSResponseFormat;
// Resource configuration
+ (NSString *)getRemoteSite;
+ (void)setRemoteSite:(NSString*)siteURL;
+ (NSString *)getRemoteUser;
+ (void)setRemoteUser:(NSString *)user;
+ (NSString *)getRemotePassword;
+ (void)setRemotePassword:(NSString *)password;
+ (SEL)getRemoteParseDataMethod;
+ (void)setRemoteParseDataMethod:(SEL)parseMethod;
+ (SEL) getRemoteSerializeMethod;
+ (void) setRemoteSerializeMethod:(SEL)serializeMethod;
+ (NSString *)getRemoteProtocolExtension;
+ (void)setRemoteProtocolExtension:(NSString *)protocolExtension;
+ (void)setRemoteResponseType:(ORSResponseFormat) format;
+ (ORSResponseFormat)getRemoteResponseType;
// Finders
+ (NSArray *)findAllRemote;
+ (NSArray *)findAllRemoteWithResponse:(NSError **)aError;
+ (id)findRemote:(NSString *)elementId;
+ (id)findRemote:(NSString *)elementId withResponse:(NSError **)aError;
// URL construction accessors
+ (NSString *)getRemoteElementName;
+ (NSString *)getRemoteCollectionName;
+ (NSString *)getRemoteElementPath:(NSString *)elementId;
+ (NSString *)getRemoteCollectionPath;
+ (NSString *)getRemoteCollectionPathWithParameters:(NSDictionary *)parameters;
+ (NSString *)populateRemotePath:(NSString *)path withParameters:(NSDictionary *)parameters;
// Instance-specific methods
- (id)getRemoteId;
- (void)setRemoteId:(id)orsId;
- (NSString *)getRemoteClassIdName;
- (BOOL)createRemote;
- (BOOL)createRemoteWithResponse:(NSError **)aError;
- (BOOL)createRemoteWithParameters:(NSDictionary *)parameters;
- (BOOL)createRemoteWithParameters:(NSDictionary *)parameters andResponse:(NSError **)aError;
- (BOOL)destroyRemote;
- (BOOL)destroyRemoteWithResponse:(NSError **)aError;
- (BOOL)updateRemote;
- (BOOL)updateRemoteWithResponse:(NSError **)aError;
- (BOOL)saveRemote;
- (BOOL)saveRemoteWithResponse:(NSError **)aError;
- (BOOL)createRemoteAtPath:(NSString *)path withResponse:(NSError **)aError;
- (BOOL)updateRemoteAtPath:(NSString *)path withResponse:(NSError **)aError;
- (BOOL)destroyRemoteAtPath:(NSString *)path withResponse:(NSError **)aError;
// Instance helpers for getting at commonly used class-level values
- (NSString *)getRemoteCollectionPath;
- (NSString *)convertToRemoteExpectedType;
//Equality test for remote enabled objects based on class name and remote id
- (BOOL)isEqualToRemote:(id)anObject;
- (NSUInteger)hashForRemote;

What is the "ObjectiveResource" in the () mean for NSObject? What is that telling Xcode and the compiler about what is happening..?
After that things look normal to me as they have various static and instance methods. I know that by doing this all user classes that inherit from NSObject now have all the extra methods for this project.
My question is what is the parenthesis are doing after the NSObject. Is that referencing a header file, or is that letting the compiler know that this class is being over ridden.
Thanks again and my apologies ahead of time if this is a dumb question but just trying to learn what I lack.
