使用uitableview部分出現問題 - 單元格在每個部分都重複

Question

先謝謝您的幫助，我無法在代碼中包裝頭。我試圖將現有的可用工具完美地分成4個部分。正如你所看到的，我有4個部分，每個部分有不同數量的行和每個部分的名稱。編譯時，這些部分正確的存在，但單元格重複。我已經嘗試了各種方法從主題上的其他帖子以及谷歌搜索的信息，但我不斷收到大量的錯誤。如果有人能告訴我我要離開的東西，我將不勝感激！謝謝。

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { 
// Return the number of sections. 
return 4; 
} 

    - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { 
switch (section) { 
    case 0: 
     return 2; 
     break; 
    case 1: 
     return 3; 
     break; 
    case 2: 
     return 2; 
     break; 
    case 3: 
     return 1; 
     break; 
} 
return 0;

    [cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator]; 
    [cell.textLabel setNumberOfLines:2]; 
} 

cell.textLabel.font = [UIFont systemFontOfSize:14.0]; 
cell.detailTextLabel.font = [UIFont systemFontOfSize:11.5]; 

switch (indexPath.row) { 
    // I would like these in Section One 
    case 0: 
     [cell.textLabel setText:@"Cell one"]; 
     [cell.detailTextLabel setText:@"subtext one"]; 
     break; 
    case 1:

// And these in Section Two 
    case 2:

     break; 
    default:

} 

return cell;   
}

，你必須在的cellForRowAtIndexPath添加

switch (indexPath.section) 

。

或if-else子句。

是這樣的：

if (indexPath.section == 0 && indexPath.row == 0) 
{ 
    // for the first row in the first section 
} 
else if (indexPath.section == 3 && indexPath.row == 2) 
{ 
    // for the 4 section and 3 row 
}
