私は次のメソッド使用しています:Xcodeの警告 - のaddObject
-(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 =コメントを、私は次のようなエラーやアプリのクラッシュを取得:
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'
私はわからないんだけど私は... Qtは、スライダーとのTextInputに等しいとき、それは動作します....間違っ

編集:更新コードを参照してください、ここで出力は次のようになります。

今私もヌル届きません。私の出力はちょうどです:
2011-07-20 01:21:04.402 MainMenu[71910:207] <CommentQuestionViewController: 0x4e0b100>
2011-07-20 01:21:04.404 MainMenu[71910:207] <Question: 0x4e55170>
