How to select range of values when using arc4random()

Question

Can I set a range of numbers when using arc4random()? For example 50-100 only.

Answer 1

In Swift you can use this (inspired by answer of @Justyn)

func generateRandomKey(fromRange rangeFrom:Int, toRange rangeTo:Int) -> Int{

    let theKey = arc4random_uniform(UInt32(rangeTo - rangeFrom)) +  UInt32(rangeFrom)
    return Int(theKey)
}

Will always give you a random range Integer.
