Size in Objective-C

In Objective-C, you can get the size of an array using the count method.

Here's an example code snippet:

NSArray *myArray = @[@"apple", @"banana", @"cherry"];
NSUInteger count = [myArray count];
NSLog(@"The size of myArray is %lu", count);

In the above example, we first declare an array called myArray with three string values. Then we use the count method to get the size of the array and store it in an unsigned integer variable called count. Finally, we use the NSLog function to print out the size of the array.

Output:

The size of myArray is 3

Similarly, you can also get the size of a mutable array by using the count method.

NSMutableArray *myMutableArray = [NSMutableArray arrayWithObjects:@"dog", @"cat", @"elephant", nil];
NSUInteger count = [myMutableArray count];
NSLog(@"The size of myMutableArray is %lu", count);

Output:

The size of myMutableArray is 3
