Question

采用以下方法:

-(void) finishQuestionnaire:(id)sender{ 
    NSString * ans;
    NSString* qt = [[[questionArray objectAtIndex:currQNum-1] question] qType];     
    if([qt isEqualToString:@"Slider"]){
        ans = [[[questionArray objectAtIndex:currQNum-1] sliderLabel]text];
    }else if([qt isEqualToString:@"Option"]){               

    }else if([qt isEqualToString:@"TextInput"]){
        ans = [[[questionArray objectAtIndex:currQNum-1] inputAnswer]text];
    }else if([qt isEqualToString:@"ImagePicker"]){

    }else if([qt isEqualToString:@"Comment"]){
        ans = [[[questionArray objectAtIndex:currQNum-1] inputAnswer]text];             
    }
    //UPDATED

NSLog(@"%@", [questionArray objectAtIndex:currQNum-1]);
NSLog(@"%@", [[questionArray objectAtIndex:currQNum-1] question]);
NSLog(@"%@", [[[questionArray objectAtIndex:currQNum-1] question] answer]);

    //[self.navigationController popToRootViewControllerAnimated:YES];
}

qt = 评论我有以下错误和 app:

 2011-07-20 00:02:04.723 MainMenu[71393:207] -[NSURLCache setAnswer:]: unrecognized selector sent to instance 0x4e29280
    2011-07-20 00:02:04.726 MainMenu[71393:207] *** Terminating app due to uncaught exception  NSInvalidArgumentException , reason:  -[NSURLCache setAnswer:]: unrecognized selector sent to instance 0x4e29280

我不敢肯定我做了什么错误......。 qt等于斜体和案文......

回答和问答

import <Foundation/Foundation.h>


@interface Answer : NSObject {
    //NSString* answerId;
    NSString* answer;
    NSString* questionId;
    NSString* entryId;
}

//@property (nonatomic, retain) NSString* answerId;
@property (nonatomic, retain) NSString* answer;

@end

@implementation Answer

@synthesize answer, questionId, entryId;

#import <Foundation/Foundation.h>
#import "Answer.h"

@interface Question : NSObject {
    NSString* qId;
    NSString* qTitle;

@implementation Question
@synthesize qId, qTitle, qNumber, sectionId, qType, answer;

-(id)init
{
    if (self = [super init])
    {
        // Initialization code here
        answer = [[Answer alloc]init];
    }
    return self;
}

-(void) dealloc{
    [answer release];
    [super dealloc];
}

Edit:见《最新守则》,这里的产出是:

2011-07-20 01:21:04.402 MainMenu[71910:207] <CommentQuestionViewController: 0x4e0b100>
2011-07-20 01:21:04.404 MainMenu[71910:207] <Question: 0x4e55170>
2011-07-20 01:21:04.404 MainMenu[71910:207] (null)

最新情况:

现在我甚至连废。我的产出只是:

2011-07-20 01:21:04.402 MainMenu[71910:207] <CommentQuestionViewController: 0x4e0b100>
2011-07-20 01:21:04.404 MainMenu[71910:207] <Question: 0x4e55170>

Answer 1

Your custom type Answer does not appear to have a method setAnswer.

确保

[[[questionArray objectAtIndex:currQNum-1] question] answer];

回归标的<代码>Answer (看来是<代码>NSURLCache)的类型,然后检查<代码>answer 财产<代码>。

EDIT:在不公布你的全源代码的情况下解决这一问题,从一开始,行走。为此,我要回答以下几点:

Of what type is [questionArray objectAtIndex:currQNum-1]?
Of what type is [[questionArray objectAtIndex:currQNum-1] question]?
Of what type is [[[questionArray objectAtIndex:currQNum-1] question] answer]?

Answer 2

或许Answer是NSURLCache的子类。在您的习俗分组负责人和执行档案中,确保你们确定并撰写了一名名为<代码>-setAnswer:的选任人。要么,要么确保您在Answere>上,而不是在上刊登。

http://www.ohchr.org。

如下:

@implementation Answer

@synthesize answer, questionId, entryId;

@end

应当加以充实。您是否在<代码>Answer.m上?
