objective-c - iphoneアプリで予想される未知のエラーを解決する方法

Question

計算で var に値を代入していますが、構文エラーが表示されます。すべての角かっこが表示されますが、エラーが発生します here is my code .

appDelegate.Same_Vaccination_Cost_Treatment_Annually_With_Guarantee=((appDelegate.Same_Vaccination_Cost_Treatment_Annually_No_Guarantee - 5000) / appDelegate.Same_Vaccination_Cost_Treatment_Annually_No_Guarantee) * ((appDelegate.Cost_Treatment_SevereEI * appDelegate.Same_Vaccination_SevereEI_Annually) + (appDelegate.Cost_Treatment_ModerateEI * appDelegate.Same_Vaccination_ModerateEI_Annually) + (appDelegate.Cost_Treatment_MildEI * appDelegate.Same_Vaccination_MildEI_Annually))) ) * appDelegate.Same_Vaccination_Horses_Per_Premise;

Answer 1

あなたのコードに従って： -

    float Same_Vaccination_Cost_Treatment_Annually_With_Guarantee;
    float Cost_Treatment_SevereEI;
    float Same_Vaccination_SevereEI_Annually;
    float Cost_Treatment_MildEI;
    float Same_Vaccination_MildEI_Annually;
    float Same_Vaccination_Horses_Per_Premise;
    float Same_Vaccination_Cost_Treatment_Annually_No_Guarantee;
    float Cost_Treatment_ModerateEI;
    float Same_Vaccination_ModerateEI_Annually;

Same_Vaccination_Cost_Treatment_Annually_With_Guarantee=(((Same_Vaccination_Cost_Treatment_Annually_No_Guarantee - 5000) / Same_Vaccination_Cost_Treatment_Annually_No_Guarantee) * (((Cost_Treatment_SevereEI * Same_Vaccination_SevereEI_Annually) + (Cost_Treatment_ModerateEI * Same_Vaccination_ModerateEI_Annually) + (Cost_Treatment_MildEI * Same_Vaccination_MildEI_Annually)) * Same_Vaccination_Horses_Per_Premise));

また、メソッドを次のように配置することもできます:-

Same_Vaccination_Cost_Treatment_Annually_With_Guarantee=((Same_Vaccination_Cost_Treatment_Annually_No_Guarantee - 5000) / Same_Vaccination_Cost_Treatment_Annually_No_Guarantee) * ((Cost_Treatment_SevereEI * Same_Vaccination_SevereEI_Annually) + (Cost_Treatment_ModerateEI * Same_Vaccination_ModerateEI_Annually) + (Cost_Treatment_MildEI * Same_Vaccination_MildEI_Annually)) * Same_Vaccination_Horses_Per_Premise;

Answer 2

まったく同じものを使用している場合

    appDelegate.Same_Vaccination_Cost_Treatment_Annually_With_Guarantee=((appDelegate.Same_Vaccination_Cost_Treatment_Annually_No_Guarantee - 5000) / appDelegate.Same_Vaccination_Cost_Treatment_Annually_No_Guarantee) * ((appDelegate.Cost_Treatment_SevereEI * appDelegate.Same_Vaccination_SevereEI_Annually) + (appDelegate.Cost_Treatment_ModerateEI * appDelegate.Same_Vaccination_ModerateEI_Annually) + (appDelegate.Cost_Treatment_MildEI * appDelegate.Same_Vaccination_MildEI_Annually)))) * appDelegate.Same_Vaccination_Horses_Per_Premise;

次に、2つのブレースが余分にあります

試す

    appDelegate.Same_Vaccination_Cost_Treatment_Annually_With_Guarantee=((appDelegate.Same_Vaccination_Cost_Treatment_Annually_No_Guarantee - 5000) / appDelegate.Same_Vaccination_Cost_Treatment_Annually_No_Guarantee) * ((appDelegate.Cost_Treatment_SevereEI * appDelegate.Same_Vaccination_SevereEI_Annually) + (appDelegate.Cost_Treatment_ModerateEI * appDelegate.Same_Vaccination_ModerateEI_Annually) + (appDelegate.Cost_Treatment_MildEI * appDelegate.Same_Vaccination_MildEI_Annually)) * appDelegate.Same_Vaccination_Horses_Per_Premise;

Answer 3

appDelegate.Same_Vaccination_Cost_Treatment_Annually_With_Guarantee=((appDelegate.Same_Vaccination_Cost_Treatment_Annually_No_Guarantee - 5000) / appDelegate.Same_Vaccination_Cost_Treatment_Annually_No_Guarantee) * ((appDelegate.Cost_Treatment_SevereEI * appDelegate.Same_Vaccination_SevereEI_Annually) + (appDelegate.Cost_Treatment_ModerateEI * appDelegate.Same_Vaccination_ModerateEI_Annually) + (appDelegate.Cost_Treatment_MildEI * appDelegate.Same_Vaccination_MildEI_Annually)) * appDelegate.Same_Vaccination_Horses_Per_Premise;

これは機能します。括弧の使用が多すぎます。
