Question

此处的相关代码：

-(UITableViewCell*) tableView:(UITableView*)tableView cellForRowAtIndexPath:(NSIndexPath*) indexPath
{
 UITableViewCell *cell;
 NSInteger currentRow = 0;
 for (int i = 0; i < [indexPath section]; i++) {
  currentRow += ((sectionNumber*) [numSections objectAtIndex:i]).num;
 }
 currentRow += [indexPath row];
 NSLog(@"[current row] %d", currentRow);
 //if (lineFound == YES){
  cell = [tableView dequeueReusableCellWithIdentifier:[NSString stringWithFormat:@"%d", currentRow]];
  if (cell == nil){
   [[NSBundle mainBundle] loadNibNamed:@"pathResultsCell" owner:self options:nil];
   cell = pathCell;
   self.pathCell = nil;
   PathTimesRow *myRow = [resultArray objectAtIndex:currentRow];  

   NSString * img = [myRow.LineOperatingCompanyID stringByAppendingString:@".gif"];
   companyImg.image = [UIImage imageNamed:img];
   line.text=myRow.LineName;
   source.text= myRow.StartPlaceFullName;
   dest.text=myRow.EndPlaceFullName;
   if (myRow.DepDateTime != myRow.FirstPlaceDepDateTime)
    TimeS.text = @"*";
   TimeS.text=[TimeS.text stringByAppendingString:[[myRow.DepDateTime substringFromIndex:11] substringToIndex:5]];
   TimeD.text=[[myRow.ArrDateTime substringFromIndex:11] substringToIndex:5];
   tmpDate=[[NSString alloc]initWithString:[myRow.DepDateTime substringToIndex:10]];
   NSLog(@"[PathSearchResult]date: %@", myRow.DepDateTime);

  }
// }

 return cell;

}

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
 return tmpDate;
}



- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
 NSLog(@"sections %d", countSections);
 if (countSections > 1) {
  NSLog(@"this is the number of sections", countSections);
  return countSections;
 }
 return 1;

}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
 if (countSections>1) {
  NSLog(@"section %d", section);
  sectionNumber * tmp= [numSections objectAtIndex:section];
  NSLog(@"rows %d", tmp.num);
  return tmp.num;
 }


 return [resultArray count];
}

NSLog表示以下奇妙的条件：

抱歉超详细的问题。出了什么问题？

Answer 1

您的代码看起来是正确的。但是当你试图在- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { return tmpDate; }设置它时，tmpDate是否真的设置了？

您是否尝试过使用字符串？

UITableView在创建之后不会显示任何部分
