Create populated in Objective-C

To create an array in Objective-C, you can use the NSArray or NSMutableArray class.

Here is an example of how to create an NSArray with three elements:

NSArray *myArray = @[@"apple", @"banana", @"orange"];

In this example, the @[] notation is used to create an NSArray with three string values. The * before the myArray variable name denotes that this is a pointer to an object of type NSArray.

Here is an example of how to create an NSMutableArray with two elements:

NSMutableArray *myMutableArray = [NSMutableArray arrayWithObjects:@"cat", @"dog", nil];

In this example, the arrayWithObjects method of NSMutableArray is used to create an NSMutableArray with two string values. The * before the myMutableArray variable name denotes that this is a pointer to an object of type NSMutableArray.

Note that the NSArray is immutable, which means that once it is created, it cannot be changed. In contrast, NSMutableArray is mutable, which means that you can add, remove, or modify elements as needed.
