Generate a random alphanumeric string in cocoa

I’m new to objective c and I would like to add the following functionality to my app:

I have a label which has default text after the app launches.
I want for that label to change to a random string each time the user clicks a button.
It does not matter if the string repeats itself eventually, as long as it is random.

I appreciate the help in advance.

You can use following code :

[[NSProcessInfo processInfo] globallyUniqueString]; 

for generating the random string.

or

You can create array that contains number of strings. Assuming you created 10 strings and put them in an array then:

int rand= arc4random()%10 
NSString *str=[array objectAtIndex:rand];
