Objective-C Language Random Integer Basic Random Integer
Example
The arc4random_uniform() function is the simplest way to get high-quality random integers. As per the manual:
arc4random_uniform(upper_bound) will return a uniformly distributed random number less than upper_bound.
arc4random_uniform() is recommended over constructions like ''arc4random() % upper_bound'' as it avoids "modulo bias" when the upper bound is not a power of two.
uint32_t randomInteger = arc4random_uniform(5); // A random integer between 0 and 4
