我有一個表格視圖,需要顯示一些問題文本及其答案類型。答案類型可以是UISwitch(single_option),UITextField(text_option)和Star Rating View(star_option)。所有問題和答案都來自服務器。因此,對於每個表格行,我需要顯示一個問題文本和答案類型,如我在下面的屏幕截圖中所述。可以有n個問題,所以我已經根據問題的數量設置了他們的框架。現在,我的問題是當我向上或向下滾動,然後問題顯示正確,但他們的答案類型是隨機出現的,而且我也沒有得到正確的單元格高度。UITableviewCell在滾動ios期間顯示不正確
請檢查,我附上我的代碼。
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
Surveys *surveys = [[Surveys alloc] init];
surveys = [arraySurveys objectAtIndex:indexPath.row];
static NSString *CellIdentifier = @"Cell";
UITableViewCell *surveysCell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!surveysCell) {
surveysCell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
UILabel *lblSurveyQuestionText = nil;
SVSegmentedControl *segment1 = nil;
UITextField *tfAnswer = nil;
//For displaying Voting Questions
lblSurveyQuestionText = [[UILabel alloc] init];
labelHeight = [self getLabelHeightForIndex:indexPath.row];
lblSurveyQuestionText.frame = CGRectMake(10, 5, 300,labelHeight);
lblSurveyQuestionText.backgroundColor = [UIColor clearColor];
lblSurveyQuestionText.text = surveys.questions;
lblSurveyQuestionText.textAlignment = NSTextAlignmentLeft;
lblSurveyQuestionText.lineBreakMode = NSLineBreakByWordWrapping;
lblSurveyQuestionText.numberOfLines = 0;
lblSurveyQuestionText.tag = 10;
[lblSurveyQuestionText sizeToFit];
lblSurveyQuestionText.textColor = [UIColor whiteColor];
[surveysCell.contentView addSubview:lblSurveyQuestionText];
//For displaying UISwitch
NSArray *arrayOption1 = [[NSArray alloc] initWithObjects:@"Yes", @"No", nil];
segment1 = [[SVSegmentedControl alloc] initWithSectionTitles:arrayOption1];
segment1.thumb.tintColor = [UIColor colorWithRed:0.6 green:0.2 blue:0.2 alpha:1];
segment1.changeHandler = ^(NSUInteger newIndex) {
NSString *selectedName = [arrayOption1 objectAtIndex:newIndex];
NSLog(@"Switch selected answer is = %@", selectedName);
};
segment1.center = CGPointMake(65, lblSurveyQuestionText.frame.size.height+27);
//For displaying text field
tfAnswer = [[UITextField alloc] init];
CGRect frameRect = CGRectMake(10, lblSurveyQuestionText.frame.size.height+13, 300, 25);
frameRect.size.height = 25;
tfAnswer.frame = frameRect;
UIView *paddingView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 7, 10)];
tfAnswer.leftView = paddingView;
tfAnswer.leftViewMode = UITextFieldViewModeAlways;
tfAnswer.textColor = [UIColor colorWithRed:(59/255.0) green:(59/255.0) blue:(59/255.0) alpha:1.0];
tfAnswer.delegate = self;
tfAnswer.font = [UIFont fontWithName:@"Helvetica Neue Medium" size:16.0];
tfAnswer.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"tf_301_23.png"]];\
tfAnswer.returnKeyType = UIReturnKeyDone;
//For displaying star view
starRatingAnswer = [[TQStarRatingView alloc] initWithFrame:CGRectMake(10, lblSurveyQuestionText.frame.size.height+10, 180, 30) numberOfStar:5];
starRatingAnswer.delegate = self;
surveysCell.selectionStyle = UITableViewCellSelectionStyleNone;
tblSurveys.tableFooterView = viewSurveysBottom;
NSLog(@"Surveys answer type is = %@", surveys.answer_type);
if ([surveys.answer_type isEqualToString:@"text_option"]) {
[surveysCell.contentView addSubview:tfAnswer];
}
else if ([surveys.answer_type isEqualToString:@"single_option"]) {
[surveysCell.contentView addSubview:segment1];
}
else{
[surveysCell.contentView addSubview:starRatingAnswer];
}
return surveysCell;
}
((UILabel *)[surveysCell.contentView viewWithTag:10]).text = surveys.questions;
return surveysCell;
}

}
請建議一些方法來克服這種情況。我已經嘗試了很多,但似乎沒有使用我的上述代碼工作。
謝謝。
