Generate Random Numbers Between Two Numbers in Objective-C

Question

I have two text boxes and user can input 2 positive integers (Using Objective-C). The goal is to return a random value between the two numbers.

I\'ve used \"man arc4

Answer 1

Objective-C Function:

-(int)getRandomNumberBetween:(int)from to:(int)to
{
    return (int)from + arc4random() % (to-from+1);
}

Swift:

func getRandomNumberBetween(_ from: Int, to: Int) -> Int 
{
    return Int(from) + arc4random() % (to - from + 1)
}

Call it anywhere by:

int OTP = [self getRandomNumberBetween:10 to:99];
NSLog(@"OTP IS %ld",(long)OTP);
NSLog(@"OTP IS %@",[NSString stringWithFormat @"%ld",(long)OTP]);

For Swift:

var OTP: Int = getRandomNumberBetween(10, to: 99)
