the code bellow:

SFRestRequest *request = [SFRestRequest requestWithMethod:SFRestMethodPOST path:@"
/services/apexrest/MyRestApi/MyFavorite" queryParams:nil];
    request.endpoint = @"/services/apexrest/MyRestApi/MyFavorite";
    [[SFRestAPI sharedInstance] sendRESTRequest:request failBlock:^(NSError *e){
        NSLog(@"error: %@", e);
    } completeBlock:^(id success){
        NSLog(@"success: %@", success);
    }];

the response print in the console:

​success: (null)

[ios mobile app]  the code blow:

-(void)launchRequest{
  SFRestRequest *request = [[SFRestRequest alloc] init]; 
  request.endpoint = @"/services/apexrest"; 
  request.method = SFRestMethodGET; 
  request.path = @"/MyRestApi/Inquiry/getInquiryDefaultValue"; 
  [[SFRestAPI sharedInstance] send:request delegate:self];
}
- (void)request:(SFRestRequest *)request didLoadResponse:(id)dataResponse { 
    NSLog(@"dataResponse: %@", [dataResponse description]);
}

the print log info is a hex stream, any one can tell me why???????   thanks
