Question

在我正在复读的“i”申请中,我有UITableView。 http://www.un.org/Depts/DGACM/index_chinese.htm 表格对其中一个单元的文字价值进行了更新。

然而,以下法典似乎产生了不想要的副作用。看来,每当UITableView复读时,就会发现UISegmentedControl(以及可能的图像——我并不肯定)相对于现有的图像。

我注意到的唯一原因是,每重新造就一个几乎让人接受的边界,就开始在被调查的联邦调查局周围形成,而且申请速度明显放缓。我非常感谢对我目前的困境提出的任何建议/编码解决办法。

// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";


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

    NSUInteger section = indexPath.section;
    NSUInteger row = indexPath.row;

    // Set up the cell...       


    //populates the personal info section
    if (section == kPersonalInfoAddSection) {

        if (row == kNameRow) {

                    //Other code irrelevant to this question was removed for the sake of clarity
        }
        else if(row == kHeightRow) {

            cell.imageView.image = [UIImage imageNamed:@"tableview_height_label.png"];
                    //THIS IS THE TEXT I M TRYING TO UPDATE
            cell.textLabel.text = [Formatter formatHeightValue:mainUser.heightInMM forZone:self.heightZone];
            cell.detailTextLabel.text = REQUIRED_STRING;

        }
    }

    //populates the units section
    if (section == kUnitsSection) {

        if (row == kHeightUnitsRow) {
            NSArray *heightUnitsSegments = [[NSArray alloc] initWithObjects:FT_AND_IN_STRING, M_AND_CM_STRING, nil];

            UISegmentedControl *heightUnitControl = [[UISegmentedControl alloc] initWithItems:heightUnitsSegments];

            CGRect segmentRect = CGRectMake(90, 7, 200, 30);
            [heightUnitControl setFrame:segmentRect];
            //[heightUnitControl setSelectedSegmentIndex:0];
            [heightUnitControl addTarget:self action:@selector(heightSegmentClicked:) forControlEvents:UIControlEventValueChanged];
            heightUnitControl.tag = kHeightSegmentedControlTag;

            cell.textLabel.text = @"Height:";
            cell.detailTextLabel.text = @"(units)";
            [cell.contentView addSubview:heightUnitControl];

            [heightUnitsSegments release];
            [heightUnitControl release];

        }
        else if(row == kWeightUnitsRow) {

                    //Other code irrelevant to this question was removed for the sake of clarity    

        }
    }

    return cell;
}

事先感谢你!

Answer 1

你们是正确的,它正在创立一个新案例,即UISegmentedControl。这是因为你使用了通用的手机识别器,@“Cell”,然后每次增加UISegmentedControl,永远不会去除。这些囚室配有UISegmentedControl,你取回了该牢房,并再次增加了控制。

你们可以使用更具体的手机识别器,如果是手机! 不详已有控制。或者每当你不使用已经控制过的卡路里,就建造一个新的牢房。

根据图像观点,你只是把细胞形象视为财产,而没有给囚室增添新的观点,这样一来就能够更换。

由于你试图更新案文,与被调查者联盟没有关系。管制我认为,你应当能够使用更具体的手机识别器,并且只增加在电池制造方面的控制。
