Why I couldn't do it that way !?

Hi

when I want to make a regular Array I can use both ways

1st

NSArray *test = [[NSArray alloc]initWithObjects: ..., nil];

2nd

NSArray *test = @[@"d",@"o",@"o"];

However in the second type of array Mutablearaay I can use the second method and it prints the objects ,but I can't remove the object by its index. I can remove it by following the old method of initializing . I want a deep explain why that happened. Thank you :)

Hi Abdulaziz Al-Zahrani ,

you might want to have a look at NSMutableArray and under "Removing Objects" there are several methods how to remove an object out of the index like e. g. - (void)removeObjectAtIndex:(NSUInteger)index.
