自定义表视图单元格中没有可见的视图 [英] No Visible View in Custom Table View Cell

问题描述

我正在做有关 tableView 和 tableViewCell 的练习.而且自定义视图单元格存在一些问题.

I am doing an exercise about tableView and tableViewCell. And I am having some problems with custom view cells.

我已经使用名为 newCellView.xib 的.xib文件创建了自己的自定义 tableViewCell .我需要.h和.m文件，我选择超类作为 UITableViewCell .

I have created my own custom tableViewCell with .xib file called as newCellView.xib. I have required .h and .m files and I choose super class as UITableViewCell.

在名为 TableViewController 的视图控制器中，我正在使用这样的默认单元格创建一个表.

In my view controller called as TableViewController I was creating a table with default cells like this.

- (UITableViewCell *)tableView: (UITableView *)tableView cellForRowAtIndexPath: (NSIndexPath *)indexPath
{
 UITableViewCell *cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil];

   cell.textLabel.text = [showNames objectAtIndex:[indexPath row]];
   cell.imageView.image = [UIImage imageNamed:[iconArray objectAtIndex:[indexPath row]]];

 return cell;
}

一旦创建了自己的自定义视图.我将 newViewCell.h 导入我的 viewController 中，并更新了这样的代码.

Once I have created my own custom view. I imported newViewCell.h into my viewController and I updated the code like this.

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

static NSString *newCellViewString = @"newCellView";

newCellView *cell = [tableView dequeueReusableCellWithIdentifier:newCellViewString];

 //newCellView *cell = [[newCellView alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:newCellView];
if (cell == nil)
{
    NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"newCellView" owner:self options:nil];
    cell = (newCellView *)[nib objectAtIndex:0];
}

但是，当我运行该应用程序时，我看到一个空白页面，就像我没有相关视图一样.也许我忘记了要添加的一些连接.我什至看不到要查看的空白单元格.只有白色的空白页.任何帮助将是巨大的.谢谢.

But when I run the app I see a blank page, like I have no related view. Maybe I forgot some connections to add. I can't even see empty cells to view. Only a white blank page. Any help would be great. Thanks.

编辑其他文件

这是我的.h和.m文件.

Here are my .h and .m files.

#import <UIKit/UIKit.h>

@interface newCellView : UITableViewCell <UITableViewDelegate>

@property (nonatomic, strong) IBOutlet UILabel *nameLabel;
@property (nonatomic, strong) IBOutlet UIImageView *iconImageView;
@property (retain, nonatomic) IBOutlet UIButton *extendButton;

@end

.m文件

#import "newCellView.h"

@implementation newCellView

@synthesize nameLabel;
@synthesize extendButton;
@synthesize iconImageView;

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
    // Initialization code
}
return self;
}

- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
[super setSelected:selected animated:animated];

// Configure the view for the selected state
}

- (void)dealloc {
[extendButton release];
[nameLabel release];
[iconImageView release];
[super dealloc];
}
@end

推荐答案

我找到了答案.除了单元格视图的位置，所有代码在我的代码中都运行良好.

I found the answer. Everything was working good in my code except the positioning of the cell view's.

项目使用自动布局作为默认属性.因此，每当我看到白页时，单元格实际上都超出了范围.我禁用了自动版式，并通过尺寸检查器设置了项目的移动属性.

Project was using autolayout as a default property. So whenever i see the white page actually cells were out of bounds. I disabled autolayout and set movement properties of the items from size inspector.

感谢您的努力.
