我有NSMutableArray9 个对象。这些对象具有许多属性，例如questionName,questionWhatRow等。
我希望能够更改NSMutableArray.
这是我的 NSMutableArray 类。
-(id) init
{
self = [super init];
if (self)
{
self.questionsArray = [[NSMutableArray alloc] init];
Question *newQuestion = [[Question alloc] init];
newQuestion.questionName = @"What is the name of the girl who has to fetch water for her family every day?";
newQuestion.questionRowName = @"Question 1";
newQuestion.questionAnswer = @"Nya";
newQuestion.questionHint = @"Maybe if you read the book you would know";
newQuestion.questionWhatRow = @"Nya";
newQuestion.questionCompleteOrNot = @"No";
newQuestion.pointForQuestion = 1;
[self.questionsArray addObject:newQuestion];
newQuestion = [[Question alloc] init];
newQuestion.questionName = @"What is Nya's sister's name?";
newQuestion.questionRowName = @"Question 2";
newQuestion.questionAnswer = @"Akeer";
newQuestion.questionHint = @"Maybe if you read the book you would know";
newQuestion.questionWhatRow = @"Nya";
newQuestion.questionCompleteOrNot = @"No";
newQuestion.pointForQuestion = 1;
[self.questionsArray addObject:newQuestion];
newQuestion = [[Question alloc] init];
newQuestion.questionName = @"What people is Nya's mother scared of when her father and sons go hunting?";
newQuestion.questionRowName = @"Question 3";
newQuestion.questionAnswer = @"Dinka";
newQuestion.questionHint = @"Maybe if you read the book you would know";
newQuestion.questionWhatRow = @"Nya";
newQuestion.questionCompleteOrNot = @"No";
newQuestion.pointForQuestion = 1;
[self.questionsArray addObject:newQuestion];
newQuestion = [[Question alloc] init];
newQuestion.questionName = @"What is Salva scared of when he is in the Akobo desert?";
newQuestion.questionRowName = @"Question 4";
newQuestion.questionAnswer = @"Lions";
newQuestion.questionHint = @"He is scared of an animal because it ate his friend Marial";
newQuestion = nil;
}
return self;
}
-(NSUInteger)count
{
return questionsArray.count;
}
- (Question *)questionAtIndex:(NSUInteger)index
{
return [questionsArray objectAtIndex:index];
}
现在，我有另一个名为 的类ScoreViewController，我希望能够将所有对象/问题的属性questionCompleteOrNot更改NSMutableArray questionsArray为@"No".
我的 ScoreView 有一个重置按钮，但我不知道该放什么来更改 to的所有 questionCompleteOrNot属性。questionsArray@"No"
对不起，这个问题很长，我试图非常具体。
编辑
这是我的 tableView 的 DetailView。
if ([[selectedQuestion questionCompleteOrNot] isEqualToString:@"No"])
{
if ([[selectedQuestion questionAnswer] caseInsensitiveCompare:answerField.text] == NSOrderedSame)
{
// Show the correct label
[correctLabel setHidden:NO];
correctLabel.text = @"Correct!";
correctLabel.textColor = [UIColor greenColor];
}
else
{
// Show the incorrect label
[correctLabel setHidden:NO];
correctLabel.text = @"Incorrect";
correctLabel.textColor = [UIColor redColor];
[incorrectPlayer play];
[[selectedQuestion questionCompleteOrNot] isEqualToString:@"Yes"];
}
// Erase the text in the answerField
answerField.text = @"";
}
if ([[selectedQuestion questionCompleteOrNot] isEqualToString:@"Yes"])
{
UIAlertView *error = [[UIAlertView alloc]
initWithTitle:@"Error"
message:@"You already answered this question. Please click the reset button on the score view to restart."
delegate:self
cancelButtonTitle:@"Okay!"
otherButtonTitles:nil];
[error show];
answerField.text = @"";
}
selectedQuestion.questionCompleteOrNot = @"Yes";
correctLabel.text = @"";
NSLog(@"Selected question's questionCompleteOrNot is %@", [selectedQuestion questionCompleteOrNot]);
