RestKit: Multiple RKClients / Changing baseURL - restkit

Question

I initialize RKClient's sharedClient in my application delegate in applicationDidFinishLaunching and it works great. I am using this clients destination URL for most of the application, however at 1 point, in 1 class (Player), I need to load user's avatars from gravatar.com. So, I had the Player class define it's own RKClient and conform to the RKRequestDelegate protocol. It then makes the request, through this new RKClient instantiation and sets the delegate of the request to self. The problem is that I never receive a response; that is
- (void)request:(RKRequest *)request didLoadResponse:(RKResponse *)response
Is never called. Here is the whole code sample:
// Player.m
#import "Player.h"
#implementation Player
# pragma mark - Accessor Synthesizers
#synthesize identifier = _identifier;
#synthesize name = _name;
#synthesize story = _story;
#synthesize emailHash = _emailHash;
#synthesize pointPercentage = _pointPercentage;
#synthesize hitPercentage = _hitPercentage;
#synthesize lastCups = _lastCups;
#synthesize shotCount = _shotCount;
#synthesize hitCount = _hitCount;
#synthesize wins = _wins;
#synthesize losses = _losses;
#synthesize gravatar = _gravatar;
# pragma mark - Instance Methods
- (void)getGravatar {
RKClient *gClient = [RKClient clientWithBaseURL:[NSURL URLWithString:#"http://gravatar.com"]];
NSString *path = [self gravatarLink];
NSLog(#"Getting Gravatar With Link: http://gravatar.com%#", path);
[gClient get:path delegate:self];
}
- (NSString *)description {
return [NSString stringWithFormat:#"{Season: [id=%i, name=%#, story=%# ]}", _identifier, _name, _story];
}
# pragma mark - RKRequest Delegate Methods
- (void)request:(RKRequest *)request didLoadResponse:(RKResponse *)response {
NSLog(#"Gravatar Back: %#", response.bodyAsString);
self.gravatar = response.body;
[[NSNotificationCenter defaultCenter] postNotificationName:#"GravatarLoaded" object:self];
}
# pragma mark - Private Methods
- (NSString *)gravatarLink {
NSString *path;
path = [NSString stringWithFormat:#"/avatar/%#?d=monsterid&r=x", _emailHash];
if([[UIScreen mainScreen] respondsToSelector:#selector(scale)] && [[UIScreen mainScreen] scale]==2)
return [path stringByAppendingString:#"&s=200"];
else
return [path stringByAppendingString:#"&s=100"];
}
#end
Also, I have tried changing the base URL of the sharedClient and just using the sharedClient for the gravatar requests. But whenever I try to change the baseURL property of the RKClient sharedClient, either of these ways:
[[RKClient sharedClient] setBaseURL:[NSURL URLWithString:#"http://gravatar.com"]];
or
[RKClient sharedClient].baseURL: [NSURL URLWithString:#"http://gravatar.com"];
I get a runtime error:
2012-04-07 15:37:23.565 MLP[34403:fb03] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSURL URLByAppendingResourcePath:queryParameters:]: unrecognized selector sent to instance 0x8bcdd50'

Answer 1

I used:
[[RKClient sharedClient] setBaseURL:[RKURL URLWithString:#"http://gravatar.com"]];
That worked for me.

Answer 2

The clientWithBaseURL: method expects an NSString, not a NSURL. Try to use
[[RKClient sharedClient] setBaseURL:#"http://gravatar.com"];

Answer 3

you just need to go to Targets-> build Settings —> other Linker Flags
As specified in the RestKit Tutorial we changed added a flag called “-ObjC-all_load” now edit that to just display “-ObjC”
this must wok for you.
