Question

I’m making my first iOS app, and am in need of some help.
Here is how it’ll work:

User enters word in a textfield, presses a button and in the label it should be like this:
[Users word] [Randomly picked word].

So I think that I should make an array with the random words and then somehow randomize them when the button is pressed to display a random word out of many after the word the user entered in the text field.

But how is it supposed to work?
Here is what I was thinking:

randomizing this (don’t know how though):

NSArray *words = [NSArray arrayWithObjects: @"Blue", @"Green", @"Red", nil ];

and here is the code for displaying the text from the textfield:

NSString *labeltext = [NSString stringWithFormat:@"%@", [textField text]];

if I put label.text = labeltext; then it displays the word typed by the user, but I’m stuck at the “displaying random word from array” part.

Any help appreciated!

    NSArray *words = [NSArray arrayWithObjects: @"Blue", @"Green", @"Red", nil ];
    NSString *str=[words objectAtIndex:arc4random()%[words count]];
    // using arc4random(int) will give you a random number between 0 and int.
    // in your case, you can get a string at a random index from your words array
