Question

我有一个简单的Interface Builder文件，它是一个Custom TableView Cell。自定义tableview单元有两个出口......

web视图
文字标签

出于某种奇怪的原因，我收到了这个错误...

我的XIB

enter image description here

这里是 CustomCell.h 上面xib的控制器......

#import <UIKit/UIKit.h>

@interface VPCustomCell : UITableViewCell
@property (strong, nonatomic) IBOutlet UIWebView *webView;
@property (strong, nonatomic) IBOutlet UILabel *titleLabel;

@end

最后是我的视图控制器，它包含实际的表视图...

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

    NSString *htmlString = @"<html><head> <meta name = \"viewport\" content = \"initial-scale = 1.0, user-scalable = no, width = 120\"/></head> <body style=\"background:#FFF;margin-top:0px;margin-left:0px\"> <div><object width=\"120\" height=\"80\"> <param name=\"movie\" value=\"http://www.youtube.com/v/1Xqn5IHbusA&f=gdata_videos&c=ytapi-my-clientID&d=nGF83uyVrg8eD4rfEkk22mDOl3qUImVMV6ramM\"></param> <param name=\"wmode\" value=\"transparent\"></param> <embed src=\"http://www.youtube.com/v/1Xqn5IHbusA&f=gdata_videos&c=ytapi-my-clientID&d=nGF83uyVrg8eD4rfEkk22mDOl3qUImVMV6ramM\" type=\"application/x-shockwave-flash\" wmode=\"transparent\" width=\"120\" height=\"80\"></embed> </object></div></body></html>";
    // Configure the cell...
    [cell.webView loadHTMLString:htmlString baseURL:[NSURL URLWithString:@"http://www.youtube.com"]];
    cell.titleLabel.text = @"Hello";

    return cell;
}

注意：在接口文件中我声明了这个并导入我的自定义单元格...

VPCustomCell *cell;

我理解的是错误是什么问题？

Answer 1

在Interface Builder中，查看Identity Inspector（option-command-3），并确保已将表的类别设置为CustomCell单元格类。

Answer 2

使用UITableViewCells时，最好处理标签而不是插座。对于您的问题，我会删除出口，在属性检查器中给Webview一个标签或者你想要的任何东西，比如100.为标签做同样的事情。然后在你的cellForRowAtIndexPath：

static NSString *CellIdentifier = @"Cell";
cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

NSString *htmlString = @"<html><head> <meta name = \"viewport\" content = \"initial-scale = 1.0, user-scalable = no, width = 120\"/></head> <body style=\"background:#FFF;margin-top:0px;margin-left:0px\"> <div><object width=\"120\" height=\"80\"> <param name=\"movie\" value=\"http://www.youtube.com/v/1Xqn5IHbusA&f=gdata_videos&c=ytapi-my-clientID&d=nGF83uyVrg8eD4rfEkk22mDOl3qUImVMV6ramM\"></param> <param name=\"wmode\" value=\"transparent\"></param> <embed src=\"http://www.youtube.com/v/1Xqn5IHbusA&f=gdata_videos&c=ytapi-my-clientID&d=nGF83uyVrg8eD4rfEkk22mDOl3qUImVMV6ramM\" type=\"application/x-shockwave-flash\" wmode=\"transparent\" width=\"120\" height=\"80\"></embed> </object></div></body></html>";
// Configure the cell...
UIWebView *thisWebView = (UIWebView*)[cell viewWithTag:100];
UILabel *thisLabel = (UILabel*)[cell viewWithTag:whateverYouWant];
[thisWebView loadHTMLString:htmlString baseURL:[NSURL URLWithString:@"http://www.youtube.com"]];
thisLabel.text = @"Hello";
return cell;

你应该很好
