Question

#import <Foundation/Foundation.h>

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

    @autoreleasepool {

        NSMutableArray *changeme =[NSMutableArray arrayWithCapacity:25];

        //[changeme addObject:[NSNumber numberWithInt:2]];

        for (int i=2; i<=100;i+=2)
        {
                [changeme addObject:[NSNumber numberWithInt:i]];

        }

        for(int x=0;x<[changeme count];x++)
        {

            NSLog(@"Item here is %i",[[changeme objectAtIndex:x]intValue]);
        }

        [changeme removeObjectAtIndex:2];
    return 0;
}

}

removeObjectAtIndex remove the object at the index.My program should print all the even numbers from 2-100. So,index[2]=6 should be delete. But,It’s not reacting like, it should be.

Answer 1

Yup its delete object at 2. When u print ur array then u r not able to see object which index is 2.

for(int x=0;x<[changeme count];x++)
        {

            NSLog(@"Item here is %i",[[changeme objectAtIndex:x]intValue]);
        }

        [changeme removeObjectAtIndex:2];
NSLog(@"%@",[changeme description]);

6 is no more in array.
