Question

我有一个普通的表，在单元格中有一些自定义，文本视图，文本字段，按钮和标签。代码如下：

标题

#define UIColorFromRGB(rgbValue) [UIColor colorWithRed:((float)((rgbValue & 0xFF0000) >> 16))/255.0 green:((float)((rgbValue & 0xFF00) >> 8))/255.0 blue:((float)(rgbValue & 0xFF))/255.0 alpha:1.0]

@interface ALCViewController : UIViewController<UITableViewDelegate,UITableViewDataSource,UITextFieldDelegate> {
    NSMutableArray *prodottiArray;
}

@property (strong, nonatomic) UITableView *prodotti;

@end

实现：

@implementation ALCViewController

#pragma mark - UITableViewDelegate

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return [prodottiArray count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell = nil;

    static NSString *AutoCompleteRowIdentifier = @"AutoCompleteRowIdentifier";

    cell = [tableView dequeueReusableCellWithIdentifier:AutoCompleteRowIdentifier];

    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle
                                      reuseIdentifier:AutoCompleteRowIdentifier];

        UITextView *productname = [[UITextView alloc] initWithFrame:CGRectMake(115, 5, 100, 105)];
        [cell addSubview:productname];
        [productname setTag:1];/**/

        UILabel *price = [[UILabel alloc] initWithFrame:CGRectMake(230, 5, 85, 26)];
        [cell addSubview:price];
        [price setTag:2];

        UIView *buttonView = [[UIView alloc] initWithFrame:CGRectMake(235, 40, 45, 56)];
        UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
        [button setFrame:CGRectMake(0, 0, 45, 56)];
        [buttonView addSubview:button];
        [cell addSubview:buttonView];
        [buttonView setTag:3];

        UIView *textfieldView = [[UIView alloc] initWithFrame:CGRectMake(235, 110, 45, 30)];
        UITextField *textfield = [[UITextField alloc] initWithFrame:CGRectMake(0, 0, 45, 30)];
        [textfield setTextColor:[UIColor blackColor]];
        [textfield setKeyboardType:UIKeyboardTypeNumbersAndPunctuation];
        [textfield setReturnKeyType:UIReturnKeyDone];
        [textfieldView addSubview:textfield];
        [cell addSubview:textfieldView];
        [textfieldView setTag:4];
    }

    NSDictionary *elemento = [[NSDictionary alloc] initWithDictionary:[prodottiArray objectAtIndex:indexPath.row]];

    [(UITextView *)[cell viewWithTag:1] setText:[elemento objectForKey:@"product_name"]];
    [(UILabel *)[cell viewWithTag:2] setText:[elemento objectForKey:@"price"]];
    [[[(UIView *)[cell viewWithTag:3] subviews] objectAtIndex:0] setTag:[indexPath item]];

    NSLog(@"[(UIView *)[cell viewWithTag:4] subviews] %d",[[(UIView *)[cell viewWithTag:4] subviews] count]);

    return cell;
}

#pragma mark - UITableViewDataSource

- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath {

}

#pragma mark - INIT

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    #pragma mark - inizializzazione prodotti

    prodottiArray = [[NSMutableArray alloc] init];

    for (int i=0; i<20; i++) {
        [prodottiArray addObject:[NSDictionary dictionaryWithObjectsAndKeys:@"12",@"price",@"This is a name",@"product_name", nil]];
    }

    #pragma mark - Costruzione tabella

    self.prodotti = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, [[UIScreen mainScreen] bounds].size.width, [[UIScreen mainScreen] bounds].size.height-30) style:UITableViewStylePlain];
    [self.prodotti setDelegate:self];
    [self.prodotti setDataSource:self];
    [self.prodotti setScrollEnabled:YES];
    [self.prodotti setHidden:NO];
    [self.prodotti setTableFooterView:[[UIView alloc] initWithFrame:CGRectZero]];
    [self.prodotti setTag:0];

    [self.prodotti setRowHeight:150];
    [self.prodotti setBackgroundColor:[UIColor clearColor]];

    [self.view addSubview:self.prodotti];
    #pragma mark
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}


@end

我将按钮和文本字段放入UIView，因为我需要为此元素添加另一个标记。

这是- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath中记录的日志。标记为4的视图始终为1个子视图，但在第五行中有3个子视图！为什么???

日志：

2013-10-23 11:23:27.660 tableTest[2703:c07] [(UIView *)[cell viewWithTag:4] subviews] 1
2013-10-23 11:23:29.478 tableTest[2703:c07] [(UIView *)[cell viewWithTag:4] subviews] 3
2013-10-23 11:23:31.814 tableTest[2703:c07] [(UIView *)[cell viewWithTag:4] subviews] 1
2013-10-23 11:23:33.415 tableTest[2703:c07] [(UIView *)[cell viewWithTag:4] subviews] 1
2013-10-23 11:23:34.148 tableTest[2703:c07] [(UIView *)[cell viewWithTag:4] subviews] 1
2013-10-23 11:23:36.651 tableTest[2703:c07] [(UIView *)[cell viewWithTag:4] subviews] 1

我正在使用Xcode5，它发生在模拟器（ios7，ios6.1）和设备（ios6.1）

有什么想法吗？

编辑1：

根据建议，我试图直接在单元格中添加视图到cell.contentView，但没有更改日志

我遇到了同样的情况。但我有一个解决方案。我刚刚更改了超过1000+的标签，它对我来说非常适合。当我搜索这个时，我得到了一个理由，原因是一些标签已经是系统使用的服务器。可以帮助你。试试吧。

UITableView，只有一个单元格中的奇数个子视图
