Undeclared identifier in Objective-C code

Am getting an undeclared identifier problem in my code. Have commented the compiler messages.

Main.m

#import <Foundation/Foundation.h>

int main (int argc, const char * argv[])
{

     @autoreleasepool {

         NSMutableArray *stocks = [[NSMutableArray alloc]init];

         NSMutableDictionary *stock;

        stock = [NSMutableDictionary dictionary];
        [stock setObject:@"AAPL" 
                  forKey:@"symbol"];

        [stock setObject:[NSNumber numberWithInt:200]
                                        forKey:@"shares"];
                                [stocks addObject:stock];

         stock = [NSMutableDictionary dictionary];
         [stock = setObject:@"GOOG" // use of undeclared identifier 'setObject'
                     forKey:@"symbol"];
         [stock = setObject:[NSNumber numberWithInt:160] // use of undeclared identifier     'setObject'
                  forKey:@"shares"];
        [stocks addObject:stock];

        [stocks writeToFile:@"/tmp/stocks/plist" 
                 atomically:YES];



        }
    return 0;
}

You've got [stock = setObject instead of just [stock setObject: Lose the equals.

Your problem is the equals sign..

 [stock **=** setObject:@"GOOG" // use of undeclared identifier 'setObject'
                 forKey:@"symbol"];
     [stock **=** setObject:[NSNumber numberWithInt:160] // use of undeclared identifier     'setObject'
              forKey:@"shares"];

Your code should be..

 [stock  setObject:@"GOOG" // use of undeclared identifier 'setObject'
                 forKey:@"symbol"];
     [stock  setObject:[NSNumber numberWithInt:160] // use of undeclared identifier     'setObject'
              forKey:@"shares"];

You do not do

[stock = setObject....

you directly do

[stock setObject....

These methods do not return any sort of value, they are void methods (talking about the -setObject method)
