iOS Random Numbers in a range

2019-02-20 15:40发布

I know I can get a random number for example from 0 to 700 using:

arc4random() % 362

But how can I get a random number in between for example 200 to 300?

(arc4random() % 100) + 200

Not to be picky, but I am pretty sure you have to add a number... if you want all the numbers from 200 to and including 300... use

200 + arc4random()%101; 

arc4random()%100 would give a random number from 0 to 99 so 300 would never occur...
