Question

我正在尝试在考试结束时向用户显示百分比。基本上我需要一行代码，将myScore除以70的问题总数。任何帮助都会非常感激。

以下是我考试结束的代码：

NSInteger endOfQuiz = [theQuiz count];
if((((questionNumber - 1) * 6) + 6) == endOfQuiz)
{
    // Game is over.
    if(myScore >= 49 )
    {
        NSString *finishingStatement = [[NSString alloc] initWithFormat:@"Practice Exam concluded. Congratulations, you have passed with a 70%% or better! \nYou scored %i out of 70!", myScore];
        theQuestion.text = finishingStatement;
        answerResult.text = @"";
        counterLabel.text = @"";        }
    else
    {
        NSString *finishingStatement = [[NSString alloc] initWithFormat:@"Practice Exam concluded. Unfortunately, you have failed with less than 70%%, keep practicing! \nYou scored %i out of 70.", myScore];
        theQuestion.text = finishingStatement;
        counterLabel.text = @"";

    }
    theLives.text = @"";
    answerResult.text = @"";
    // Make button 1 appear as a reset game button
    restartGame = YES;
    [answerOne setHidden:NO];
    [answerOne setTitle:@" Try this Practice Exam again" forState:UIControlStateNormal];

}

Answer 1

c中的除法运算符（因而是Objective-C）是/。

myScore * 100 / 70

在Objective C中显示百分比
