在uitableview中插入行时'NSInternalInconsistencyException'iphone

Question

在我的应用程序中，我使用NSNotificationCenter批量返回10个用户对象。当我得到10个对象时，我想在表格视图中插入这些数据。对于这个我使用下面的代码

- (void)viewDidAppear:(BOOL)animated { 

    recordCounter = 0; 
    noOfRowsCounter = 0; 

    // Some code 
} 

- (void) gotNotification: (NSNotification *) notification { 

    NSMutableArray *tempArray = [[notification userInfo]valueForKey:KEY]; 

    NSLog(@"recordCounter BEFORE=> %d",recordCounter); 
    NSLog(@"noOfRowsCounter BEFORE=> %d",noOfRowsCounter); 

    self.insertIndexPaths = [[NSMutableArray alloc] init]; 
    for (User *user in tempArray) 
    { 
     [self.contactsArray addObject:user]; 

     recordCounter++; 
    } 

    for (noOfRowsCounter = noOfRowsCounter; noOfRowsCounter < recordCounter; noOfRowsCounter++) { 

     [self.insertIndexPaths addObject:[NSIndexPath indexPathForRow:recordCounter inSection:0]]; 

    } 

    NSLog(@"recordCounter AFTER=> %d",recordCounter); 
    NSLog(@"noOfRowsCounter AFTER=> %d",noOfRowsCounter); 
    NSLog(@"self.insertIndexPaths count=> %d",[self.insertIndexPaths count]); 
    [contactsTableView beginUpdates]; 
    [contactsTableView insertRowsAtIndexPaths:self.insertIndexPaths 
          withRowAnimation:UITableViewRowAnimationNone]; 
    [contactsTableView endUpdates]; 

    [self.insertIndexPaths removeAllObjects]; 
} 

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView 
{ 
    return 1; 
} 

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
{ 

    // I am doing this as I have 2 records in single row 

    if ([self.insertIndexPaths count]%2 == 0) { 

     NSLog(@"In IF::rows:: %d",[self.insertIndexPaths count]/2); 
     return [self.insertIndexPaths count]/2; 
    } 
    else { 
     NSLog(@"In ELSE::rows:: %d",[self.insertIndexPaths count]/2+1); 
     return [self.insertIndexPaths count]/2 + 1; 
    } 
} 

如果我跑我的应用程序，我得到以下错误&我的应用程序崩溃。这里是我的控制台日志

我想在表格视图中添加这些记录。我怎样才能做到这一点。由于

UPDATE：的cellForRowAtIndexPath准则

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    static NSString *CellIdentifier = @"Cell"; 

    ContactCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 

    if (cell == nil) 
    { 
     NSArray *cellArray=[[NSBundle mainBundle] loadNibNamed:@"ContactCell" owner:self options:nil]; 
     //NSLog(@"cellArray count => %d",[cellArray count]); 
     cell=[cellArray objectAtIndex:0]; 
    } 

    // Configure the cell... 

    // For showing 2 records in single row 

    int row = indexPath.row * 2; 
    if (row <= [self.contactsArray count]) 
    { 
     User *user = [self.contactsArray objectAtIndex:row]; 
     NSLog(@"In ROW: %@",user.firstName);

     cell.secondNameLabel.text=[NSString stringWithFormat:@"%@",nameString]; 
    } 

    return cell; 
}

根据数据要在在部分行，但你的 self.insertIndexPaths的数目返回图5是具有10条索引路径

[contactsTableView insertRowsAtIndexPaths:self.insertIndexPaths 
         withRowAnimation:UITableViewRowAnimationNone]; 

这些行指定要插入的10行，如在错误明确提到在更新之后您获得的行数应该等于在部分中的行数中返回的值。

与

int presentrows = [yourtablename numberOfRowsInSection:0]; 
    int Finalnumberofrows; 
    if ([self.insertIndexPaths count]%2 == 0) { 
    Finalnumberofrows = [self.contactsArray count]/2; 
} 
else { 
    Finalnumberofrows = [self.contactsArray count]/2 + 1; 
} 
    for (presentrows; presentrows < Finalnumberofrows; presentrows++) { 

    [self.insertIndexPaths addObject:[NSIndexPath indexPathForRow:presentrows inSection:0]]; 

} 

更换线

for (noOfRowsCounter = noOfRowsCounter; noOfRowsCounter < recordCounter; noOfRowsCounter++) { 

     [self.insertIndexPaths addObject:[NSIndexPath indexPathForRow:recordCounter inSection:0]]; 

    } 

，并在索引方法 替换 表视图细胞用于行 - （NSInteger的）的tableView：（UITableView的*）的tableView numberOfRowsInSection：（NSInteger的）部分 {

// I am doing this as I have 2 records in single row 

if ([self.contactsArray count]%2 == 0) { 

    NSLog(@"In IF::rows:: %d",[self.insertIndexPaths count]/2); 
    return [self.contactsArray count]/2; 
} 
else { 
    NSLog(@"In ELSE::rows:: %d",[self.insertIndexPaths count]/2+1); 
    return [self.contactsArray count]/2 + 1; 
} 

}

真正的错误后终止应用程序上市，由于未捕获的异常。
它说：部分0中的行数无效。更新（5）后现有部分中包含的行数必须等于更新前（0）中该部分中包含的行数加上或减去从该部分插入或删除的行数（10插入，0删除）

那么，什么问题？你有0行，然后插入10，现在说它有5个？没有任何意义。你应该检查你的-tableView:numberOfRowsInSection:实现。

我只是看到你想要在单行中显示两条记录。这没有意义，真的。它使该表视图动画变得不必要的复杂。
但是，如果你想坚持这一点，你可能不会告诉桌子你插入了10行而是5行。
