Question

I have two textFields where the user types into some words.

Then, when pressing a button, i want the words to randomize and then the user displays the randomized result.

I have this code:

-(IBAction) randomInp{

    NSString *first = firstField.text;
    NSString *second = secondField.text;

    NSString *result = //here it should randomize the words
    //Display randomized word
    textview.text    = //should display result
}

where firstField and secondField are respectively the first and the second UITextFields. Then i don’t know how to proceed!

I was thinking of set a switch condition. If it’s 0 then returns *first, if it’s 1 then returns *second. Am i right?

Any help appreciated

EDIT

Solved!

If anyone needs:

    -(IBAction) randomInp{

    NSString *first = firstField.text;
    NSString *second = secondField.text;
    int text = rand() % 2;
    switch (text) {
        case 0:
            textview.text = first;
            break;
        case 1:
            textview.text = second;
            break;
        default:
            break;
    }
}

The answer that SSteve gave works great, too! For anyone who needs:

NSString *result = random() & 1 ? first : second;

Answer 1

To choose between two values you can use random() and check the value of a bit:

NSString *result = random() & 1 ? first : second;

Put a call to srandomdev() somewhere in your initialization code to avoid having the same sequence of values every time your program runs. You may also need #include <stdlib.h>
