An easier and safer to use interface for good, cryptographically secure, random.
CBHRandom
provides class methods for producing random data of fixed and variable length with bounding constraints.
Generate a random NSUInteger
:
NSUInteger randInt = [CBHRandom randomUnsignedInteger];
Generate a random NSUInteger
less then 128 inclusive:
NSUInteger randInt = [CBHRandom randomUnsignedIntegerWithBound:128];
Generate a random NSUInteger
between 64 and 128 inclusive:
NSUInteger randInt = [CBHRandom randomIntegerBetweenLower:64 andUpperBound:128];
Shuffling an Array:
NSArray *array = @[@1, @2, @3, @4, @5];
NSArray *shuffledArray = [array arrayByShuffling];
Shuffling an Array in-place:
NSMutableArray *array = [NSMutableArray arrayWithObjects:@1, @2, @3, @4, @5, nil];
[array shuffle];
Requesting a random object from Array:
NSArray *array = @[@1, @2, @3, @4, @5];
NSNumber *number = [array randomObject];
