我有一個UITableView。它是動態表格。當你觸摸「添加文件」按鈕時，我正在創建一個新的部分和行。如果再次觸摸，我只創建一行。當你點擊「添加數字」按鈕時，我正在創建一個新的部分和行。如果再次觸摸，我只創建一行。還行吧。但是，如果您刪除第一部分，則第二部分不會將焦點置於頂部。我添加了一些截圖和我的所有代碼。如何刪除UITableView節頭去除後創建的空間？
請幫幫我。
這是我的第一個屏幕
我增加了一個 「文件」 和兩個 「數量」
而且我刪除了 「文件」但第二節沒有上漲。
代碼：
#import "ViewController.h"
@interface ViewController()
@end
@implementation ViewController
@synthesize tblListe,btnCancel,btnEdit;

[super viewDidLoad];
self.automaticallyAdjustsScrollViewInsets = NO;

以供將來參考修改您的截屏的尺寸會讓你的問題更方便用戶的朋友，目前也很難理解問題的圖像是太大的屏幕 – 2015-02-06 00:39:51
你說得對。謝謝你的建議。我編輯了我的問題。仍然在等待解決方案:( – 2015-02-06 07:09:52
