iOS Converting an int into an NSNumber, then saving to an array.

[Jeremy1026]

I have everything set up to save to the array, but since NS(Mutable)Array's cant store int's, I have to convert my int to an NSNumber, this is where I am getting stuck. I can't figure out how to convert the int.

I tried:

(NSNumber *)numberWithInt:(scoreVar)100;

(scoreVar *)numberWithInt:(int)100;

(NSNumber *)numberWithInt:(int)100;

No luck though

 

[neoserver]

NSNumber *yourNumber = [NSNumber numberWithInt:your_int_variable];

Should be what you're after. your_int_variable is the int variable.

 

[Jeremy1026]

NSNumber *yourNumber = [NSNumber numberWithInt:your_int_variable];

Should be what you're after. your_int_variable is the int variable.

When I do that, I get the following error when attempting to save it to the array:

"warning: passing argument 1 of 'setScoreName:' from distinct Objective-C type"

Here is my code for setting the array value:

		[newPerson setScoreName:scoreVarObj];

What exactly are newPerson and scoreVarObj?

What exactly are newPerson and scoreVarObj?

newPerson where in the array my objects are stored. scoreVarObj is the NSNumber created by the int.

This is the full code of where I save the data

[newPerson setFirstName:@"Jeremy"];   NSLog(@"%@", newPerson.firstName);
		[newPerson setScoreName:scoreVarObj];     NSLog(@"%@", newPerson.scoreName);
		[personArray insertObject:newPerson atIndex:[personArray count]];

I have the encoding/decoding in its own NSObject File. Here is the implimentation of that file.

@implementation score
@synthesize firstName, scoreName;

- (id) init {
	if(self = [super init]) {
		firstName = [[NSString alloc] init];
		scoreName = [[NSString alloc] init];
	}
	
	return self;
}

- (void) dealloc {
	[firstName release];
	[scoreName release];
	[super dealloc];
}

- (id) initWithCoder:(NSCoder *)coder {
	firstName = [[coder decodeObjectForKey:@"firstName"] retain];
	scoreName = [[coder decodeObjectForKey:@"scoreName"] retain];
	return self;
}


- (void) encodeWithCoder:(NSCoder *)encoder {
	[encoder encodeObject:firstName forKey:@"firstName"];
	[encoder encodeObject:scoreName forKey:@"scoreName"];
}


@end

Right, so scoreName is an NSString and you are trying to set it to an NSNumber.

Ok, I fixed it so that everytime scoreName is mentioned, its mentioned as an NSNumber. But I get an error when I try to add the NSNumbers to the array. The error from the debugger is

The error is exactly what it is telling you- NSNumber does not have a function called isEqualToString, but you are trying to call isEqualToString on some NSNumber somewhere.
