Question

我在UITableView中尝试存储记录，从表单重新加载数据。为此，当用户按下添加按钮，这样就应该将多个标签添加到第一个indexPath，然后再次重新点击添加按钮，必须先将多个单元格添加到第二个单元格中。

我希望将数据存储在

中

MyArray ({
  firstindex: 1st record
  firstindex: 2nd record
}
{
  secondindex : 1st record
  secondindex : 2nd record
})

记录来自UITextView，并在每个添加按钮上保存到表中，单击每行包含多个条目

- (IBAction) Add
{
      [myDict setObject:countryTxt.text forKey:@"Country"];
        [myDict setObject:cityTxt.text forKey:@"City"];
        [myDict setObject:EscortsNumTxt1.text forKey:@"people"];
        [myDict setObject:fromDate.text forKey:@"Datetogo"];
        [myDict setObject:toDate.text forKey:@"Datetoreach"];

        [moreArr addObject:myDict];

        NSLog(@"moreDict %@",moreArr);

        numberOfrows++;

        [moreTable reloadData];
}

我已经通过这种方式实现但是在TableView Cell上显示重复数据，我不包括UILabel代码的框架，因为只在fetchng中遇到问题

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

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc]    initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; 
}

countrylbl.text = [[moreArr objectAtIndex:indexPath.row] objectForKey:@"Country"];
        citylbl.text = [[moreArr objectAtIndex:indexPath.row] objectForKey:@"City"];
        people.text = [[moreArr objectAtIndex:indexPath.row] objectForKey:@"people"];
        toDateLbl.text = [[moreArr objectAtIndex:indexPath.row] objectForKey:@"Datetogo"];
        fromDteLbl.text = [[moreArr objectAtIndex:indexPath.row] objectForKey:@"Datetoreach"];
}

尝试像你的方法一样检索一次数组

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc]    initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; 
    }


    NSArray *results = [[NSArray alloc] initWithArray:[moreArr objectAtIndex:indexPath.row]];

    NSLog("%@",results); //Check that everything is in the right place

    // DO STUFF

    [results release];

}

解决方案，因为NSMutableDictionary覆盖了我不知道的内容，所以我在函数中分配了它

    moreTableDict = [[NSMutableDictionary alloc] init];

    [myDict setObject:countryTxt.text forKey:@"Country"];
    [myDict setObject:cityTxt.text forKey:@"City"];
    [myDict setObject:EscortsNumTxt1.text forKey:@"people"];
    [myDict setObject:fromDate.text forKey:@"Datetogo"];
    [myDict setObject:toDate.text forKey:@"Datetoreach"];

    [moreArr addObject:myDict];

这对我有用

在NSMutableArray中的NSDictionary中显示tableView中的数据
