What does this warning mean in Xcode? - objective-c

Question

I have a resource which is fetched from a JSON API.
The JSON is parsed into a NSDictionary which, in this case is called game.
I'm creating a new instance of my Game class based on the attributes from the JSON.
Game class has a property called userRegistered which is defined as follows:
// in Game.h
#interface
#property (nonatomic, assign) BOOL userRegistered;
// elsewhere in my code I have
Game *newGame = [[Game alloc] init];
newGame.userRegistered = ([game objectForKey:#"user_registered"] > 0);
The "user_registered" key in the dictionary will always be either 1 or 0.
Xcode warns me the I have -
warning: Semantic Issue: Incompatible integer to pointer conversion passing 'int' to parameter of type 'BOOL *' (aka 'signed char *')
Can someone please explain the issue and how I might resolve it?
Update
My full game class is defined as follows:
#import <Foundation/Foundation.h>
#interface Game : NSObject
#property (nonatomic, copy) NSString *name;
#property (nonatomic, copy) NSString *photoURL;
#property (nonatomic, copy) NSString *gameURL;
#property (nonatomic, assign) BOOL *userRegistered;
#end
// Game.m
#import "Game.h"
#implementation Game
#synthesize name = _name;
#synthesize partnerName = _partnerName;
#synthesize photoURL = _photoURL;
#synthesize gameURL = _gameURL;
#synthesize userRegistered = _userRegistered;
#end
I'm getting the error in one of my ViewControllers in this method
// api_response.body has just been set to an __NSCFArray containing
// NSDictionaries by AFNetworking
NSDictionary *game;
Game *newGame;
for (game in api_response.body){
newGame = [[Game alloc] init];
NSLog(#"Creating a new game");
// set attributes for new game instance
newGame.name = [game objectForKey:#"name"];
newGame.photoURL = [game objectForKey:#"photoURL"];
// user registered is either 0 (false) or 1 (true)
newGame.userRegistered = [[game objectForKey:#"user_registered"] intValue];
// add the game instance to the appropriate array
[self addGameToGamesArray:newGame];
newGame = nil;
}
The warning shows over newGame.userRegistered = [[game objectForKey:#"user_registered"] intValue];

Answer 1

[game objectForKey:#"user_registered"] is likely giving you an NSNumber object. You probably mean instead to compare the integer value inside that NSNumber object.
([[game objectForKey:#"user_registered"] intValue] > 0)
UPDATE in response to your update:
Your problem is with how you're declaring your BOOL property - you have a * that you need to remove.
#property (nonatomic, assign) BOOL *userRegistered;
should be
#property (nonatomic, assign) BOOL userRegistered;

Answer 2

I was able to solve this issue by simply using boolValue
game.userRegistered = [[json objectForKey:#"user_registered"] boolValue];
Thanks all for the help

Answer 3

objectForKey function will return an objective-c instance.
([[game objectForKey:#"user_registered"] boolValue] > 0)

Answer 4

([game boolForKey:#"user_registered"]==YES)
