如何在xcode中求和临时变量的值

Question

我希望TempScore在保存后立即返回0，并将旧值添加到Score变量

中

if (self.currentQuestion < [self.questions count]) {


_TempScore = x;
_Score = y;
_Score = x + y;
x = 0;
}

为什么不起作用？

编辑：让它发挥作用

self.x = self.TempScore;

self.y = self.Score;

self.Score = self.x + self.y ;

self.TempScore = 0;

Answer 1

通过这样做来实现它

self.x = self.TempScore;
self.y = self.Score;
self.Score = self.x + self.y ;
self.TempScore = 0;
