我有一个叫count的整数,我希望它在1或17或33到永远相同的序列,即count + = 16 第一个球被取消隐藏,同样的事情,当计数到达2或18或34永远相同的顺序,即计数+ = 16,第二个球未被隐藏 起初我输入了这段代码,但是如果条件
,很难用增量键入所有数字。if(count == 1 || count == 17 || count == 33 || count == 49 || count == 65 || count == 81 || count == 97 || count == 113 || count == 129 || count == 145 || count == 161 || count == 177 || count == 193 || count == 209 || count == 225 || count == 241)
{
_firstBall.hidden = NO;
}
if(count == 2 || count == 18 || count == 34 || count == 50 || count == 66 || count == 82 || count == 98 || count == 114 || count == 130 || count == 146 || count == 162 || count == 178 || count == 194 || count == 210 || count == 226 || count == 242)
{
_secondBall.hidden = NO;
}
答案 0 :(得分:3)
试试这个:
if( ((count-1) % 16) == 0) {
_first.hidden = NO;
}
if( ((count-2) % 16) == 0) {
_secondBall.hidden = NO;
}
答案 1 :(得分:0)

运算符返回整数余数(或模数)。你的第一个序列:1,17,33是16 * n + 1所以剩下的除以16是1.同样你的第二个序列是16 * n + 2.
所以你可以:
switch (count % 16) // switch on the remainder of division by 16
{
case 1:
_firstBall.hidden = NO; break;
case 2:
_secondBall.hidden = NO; break;
// add more cases if needed
}
