Setting up a class identifier to be called when logging array data - objective-c

Question

Hey stackOverflow community. I am working through Big Nerd Ranch's Objective C book and have come across the fun chapter on defining and setting up classes (chapter 17 if you're familiar). In it the challenge has us write a program where we define a stock class with several properties and instance variables. I have been able to get the program to work as asked but I want to tinker a little with it to get it to also NSLog a stockName so I can see what stock is associated with its properties.
Basically, is there a way to make the code more concise for this block:
NSString *appleName = #"AppleInc";
[Apple setStockIdentifier:appleName];
Maybe more like this:
[Apple setStockIdentifier:"AppleInc"];
I tried setting the property as a char in the class file but couldnt get it to work. Im new to this but I'm thinking that declaring a new NSString for the stockIdentifier value is extra code that isn't needed. Any feedback would be greatly appreciated.
Below is what I have for the main file:
#import <Foundation/Foundation.h>
#import "StockHolding.h"
int main(int argc, const char * argv[])
{
#autoreleasepool {
StockHolding *Apple = [[StockHolding alloc] init];
NSString *appleName = #"AppleInc";
[Apple setStockIdentifier:appleName];
[Apple setPurchaseSharePrice:2.30];
[Apple setCurrentSharePrice:4.50];
[Apple setNumberOfShares:40];
StockHolding *HomeDepot = [[StockHolding alloc] init];
NSString *homeDepotName = #"Home Depot Inc";
[HomeDepot setStockIdentifier:homeDepotName];
[HomeDepot setPurchaseSharePrice:12.19];
[HomeDepot setCurrentSharePrice:10.56];
[HomeDepot setNumberOfShares:90];
StockHolding *Cisco = [[StockHolding alloc] init];
NSString *ciscoName = #"Cisco Inc";
[Cisco setStockIdentifier:ciscoName];
[Cisco setPurchaseSharePrice:45.10];
[Cisco setCurrentSharePrice:49.51];
[Cisco setNumberOfShares:210];
NSMutableArray *listOfStocks = [NSMutableArray arrayWithObjects:Apple, HomeDepot, Cisco, nil];
for (StockHolding *currentStock in listOfStocks) {
NSLog(#"%#, Purchase Share Price: %.2f; Current value: %.2f; Number of shares: %i",[currentStock stockIdentifier],[currentStock purchaseSharePrice], [currentStock currentSharePrice], [currentStock numberOfShares]);
}
}
return 0;
}
Below is the contents of StockHolding.h:
#import <Foundation/Foundation.h>
#interface StockHolding : NSObject
{
//char stockIdentifier;
float purchaseSharePrice;
float currentSharePrice;
int numberOfShares;
}
#property NSString *stockIdentifier;
#property float purchaseSharePrice;
#property float currentSharePrice;
#property int numberOfShares;
-(float) costInDollars; //purchaseSharePrice * numberOfShares;
-(float) valueInDollars; //currentSharePrice * numberOfShares;
#end
And here is StockHolding.m:
#import "StockHolding.h"
#implementation StockHolding
#synthesize currentSharePrice, purchaseSharePrice, numberOfShares, stockIdentifier;
-(float)costInDollars;
{
return (purchaseSharePrice * numberOfShares);
}
-(float)valueInDollars;
{
return (currentSharePrice * numberOfShares);
}
#end

This is simply a syntax error.
[Apple setStockIdentifier:"AppleInc"];
Should be...
[Apple setStockIdentifier:#"AppleInc"];
