避免ios中过多If语句的最佳实践

Question

你们可能都遇到过以下场景：

-(int) fightMath(int one, int two) {

if(one == 0 && two == 0) { result = 0; }
else if(one == 0 && two == 1) { result = 0; }
else if(one == 0 && two == 2) { result = 1; }
else if(one == 0 && two == 3) { result = 2; }
else if(one == 1 && two == 0) { result = 0; }
else if(one == 1 && two == 1) { result = 0; }
else if(one == 1 && two == 2) { result = 2; }
else if(one == 1 && two == 3) { result = 1; }
else if(one == 2 && two == 0) { result = 2; }
else if(one == 2 && two == 1) { result = 1; }
else if(one == 2 && two == 2) { result = 3; }
else if(one == 2 && two == 3) { result = 3; }
else if(one == 3 && two == 0) { result = 1; }
else if(one == 3 && two == 1) { result = 2; }
else if(one == 3 && two == 2) { result = 3; }
else if(one == 3 && two == 3) { result = 3; }

return result;

}

简而言之，如何在Objective-C的氛围中有效地简化上述场景？

有什么建议/想法/解决方案吗？干杯：）

编辑：供参考，从这里拍摄的场景。我希望这个问题可以节省哪怕一秒钟需要的开发人员。

Answer 1

目标C是建立在C之上的。因此，任何好的C解决方案也适用于目标C

int result[][4] = {
    { 0, 0, 1, 2 },
    { 0, 0, 2, 1 },
    { 2, 1, 3, 3 },
    { 1, 2, 3, 3 }
};
return result[one][two]

据我所知，对于此类问题，没有针对C语言的客观良好实践。
