iPhone数学并没有完全合适

Question

我正在添加数组中保存的值,但总和是实际应该是+1.

//update totalscore
    uint newTotalScore;

    for (uint i=0; i< [bestscoresArray count] ; i++) {      
        newTotalScore += [[bestscoresArray objectAtIndex:i] intValue];  

    }


    totalscore = newTotalScore;

//输出l1bestscore = 15900,l2bestscore = 7800,l3bestscore = 81000,l4bestscore = 81000,l5bestscore = 0,l6bestscore = 0,l7bestscore = 0,l8bestscore = 0,l9bestscore = 0,l10bestscore = 0,totalscore = 185701

如您所见,totalscore输出为185701,但所有值的总和为185700.

有人会有任何想法为什么会这样吗？

谢谢,

您必须定义newTotalScore初始值:

uint newTotalScore = 0;

否则它将是未定义的.在你的情况下,1它可能是任何其他价值.
