pointer from integer without a cast

[throwd21]

Hey guys

I'm having a problem trying to store information in userdefaults. I dont understand every forum i check shows that I'm creating storing the file correctly.

In the header file.

int *score;
@property(nonatomic) int *score;


In the Implementation file...

NSUserDefaults *gameDefaults = [NSUserDefaults standardUserDefaults];
//int a = score;
int *num = score;
[gameDefaults setInteger:num forKey:@"gameScore"];

THIS IS WHERE THE WARNING COMES IN...
WARNING ARGUMENT SETINTEGER MAKES "pointer from integer without a cast"


//[gameDefaults setObject:score forKey:@"gameScore"];
//[gameDefaults setInteger:number forKey:@"gameScore"];
[gameDefaults setObject:sound forKey:@"gameSound"];
[gameDefaults setFloat:gameLoopSpeed forKey:@"theGameLoopSpeed"];
[gameDefaults setFloat:delayGameLoopSpeed forKey:@"theDelayGameLoopSpeed"];
[gameDefaults setObject:[NSMutableString stringWithFormat:gameDifficulty] forKey:@"theGameDifficulty"];

[gameDefaults synchronize];

1. Why is your score variable stored as a pointer in the first place ?

2. Assuming you really need the pointer, you should do something like :

int val=*score;

[gameDefaults setInteger:val forKey:@"gameScore"];

warmi is right. You don't want a pointer. Perhaps you are so used to all Objective C variables being declared with a '*' before their name that you forgot what the '*' means. It means the variable is a pointer. All Objective C objects that inherit from NSObject are referenced by pointers, so that is why you see the '*' so much. But an integer like score is not an Objective C object. It is a primitive C variable. As such, it can be referred to directly, without the '*'.
