我附加了TableViewController和SearchDisplayController。它检查当前tableView是搜索还是正常，然后设置变量，然后使用此数据填充表。这是来源：
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSDictionary *item;
if(tableView == self.searchDisplayController.searchResultsTableView){
item = [self.search objectAtIndex:indexPath.row];
} else {
item = [self.results objectAtIndex:indexPath.row];
}
static NSString *CellIdentifier = @"Cell";
/********* ERROR HAPPENS HERE!!!!! **********/
UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:@"Cell"];
/*********************************************/
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
UIImageView *iconView = [[UIImageView alloc] initWithFrame:CGRectMake(5.0, 5.0, 44.0, 44.0)];
iconView.tag = 100;
[cell.contentView addSubview:iconView];
UILabel *title = [[UILabel alloc] initWithFrame:CGRectMake(57.0, 5.0, 249.0, 29.0)];
title.tag = 101;
title.font = [UIFont fontWithName:@"AmericanTypewriter-Bold" size:15.0];
title.textColor = [UIColor colorWithRed:255.0f/255.0f green:128.0f/255.0f blue:0.0f/255.0f alpha:1.0];
[cell.contentView addSubview:title];
UILabel *subtitle = [[UILabel alloc] initWithFrame:CGRectMake(57.0, 28.0, 249.0, 21.0)];
subtitle.tag = 102;
subtitle.font = [UIFont fontWithName:@"HelveticaNeue-Medium" size:12.0];
subtitle.textColor = [UIColor colorWithRed:179.0f/255.0f green:179.0f/255.0f blue:179.0f/255.0f alpha:1.0];
[cell.contentView addSubview:subtitle];
} else {
UIImageView *iconView = (UIImageView *)[cell viewWithTag:100];
if([[item valueForKey:@"categories"] count] == 0){
UIImage *img = [UIImage imageNamed:@"venue"];
iconView.frame = CGRectMake(iconView.frame.origin.x, iconView.frame.origin.y, img.size.width, img.size.height);
[iconView setImage: img];
} else {
NSDictionary *iconDict = [[[item valueForKey:@"categories"] objectAtIndex:0] valueForKey:@"icon"];
NSString *icon = [NSString stringWithFormat:@"%@bg_44%@", [iconDict valueForKey:@"prefix"], [iconDict valueForKey:@"suffix"]];
[iconView setImageWithURL:[NSURL URLWithString:icon] placeholderImage:[UIImage imageNamed:@"venue"]];
}
UILabel *title = (UILabel *)[cell viewWithTag:101];
title.text = [item valueForKey:@"name"];
UILabel *subtitle = (UILabel *)[cell viewWithTag:102];
subtitle.text = [[item valueForKey:@"location"] valueForKey:@"address"];
}
UIView *bgColorView = [[UIView alloc] init];
[bgColorView setBackgroundColor:[UIColor colorWithRed:255.0f/255.0f green:128.0f/255.0f blue:0.0f/255.0f alpha:1.0]];
[cell setSelectedBackgroundView:bgColorView];
return cell;
}
我遇到了一个错误，当代码遇到尝试dequeueReusableCell的行时，会崩溃应用程序。在大多数现代iOS设备中，它都有效。我已经看到它适用于我的iPhone5，朋友的iPhone4和更新版本的iPad。但是在某些设备中 - 包括我的第一代iPad（安装了iOS5） - 这条线路崩溃了。没有有用的错误消息。我得到的只是典型的“（lldb）”消息。甚至不是数组超出范围的异常类型。堆栈跟踪仅显示它在dequeueReusableCellWithIdentifier内部中断。这是堆栈跟踪：

知道为什么会这样吗？
答案 0 :(得分：2)
当你将可重用单元格出列时，你应该使用参数中传递的tableView而不是你自己已知的self.tableView。对于搜索视图，这两个将不会相同，可能会导致问题。像这样：
UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];

终于找到了一个解决方案（我甚至不知道为什么它的工作原理的详细信息）。事实证明，在某些情况下，您必须取消选中“使用自动布局”设置。 http://www.seifeet.com/2012/12/ios-nib-data-is-invalid-exception-with.html
