Capitalized NSArray of Strings?

Question

I have an NSarray called array. And it look like this

array = @[@"one", @"two", @"three"];

I want this array to be capitalized. What is the best way to go about this. I can only think of making an NSMutableArray called mutableArray.

And do something like this

for(int i = 0; i < array.lenght; i++) {
    self.mutableArray = addObject:[array[i] capitalizedString];
}

Or is there another better way?

Answer 1

The magic method you are looking for does in fact exist.

NSArray *array = @[@"one", @"two", @"three"];
NSArray *capArray = [array valueForKeyPath:@"capitalizedString"];

Answer 2

SWIFT

You Can use map

let array = ["one", "two", "three"]
let upercaseArray = array.map({$0.uppercased()})

now you have upercaseArray like ["ONE","TWO","THREE""]
