我如何使用C4Alpha Api生成随机数字?

最佳回答

在C4中,你可以使用C4Math类,该类有称为随机Int的一类级方法。

<代码>[C4Math arbitraryInt:255];将给你0至255的随机号码。

还有一个<条码>。 方法......

<代码>[C4Math arbitraryInt BetweenA:100和B:200],将给你随机发放 10至200年

在一生中,这些方法就是这样:

+(NSInteger)randomInt:(NSInteger)value {
    srandomdev();
    return ((NSInteger)random())%value;
}

+(NSInteger)randomIntBetweenA:(NSInteger)a andB:(NSInteger)b{
    NSInteger returnVal;
    if (a == b) {
        returnVal = a;
    }
    else {
        NSInteger max = a > b ? a : b;
        NSInteger min = a < b ? a : b;
        NSAssert(max-min > 0, @"Your expression returned true for max-min <= 0 for some reason");
        srandomdev();
        returnVal = (((NSInteger)random())%(max-min) + min);
    }
    return returnVal;
}
