UITableViewCell 遇到问题
我正在使用新的 iOS5 TableView 样式代码，但我似乎遇到了问题。每当调用 Searching = true 函数时，它都会崩溃。我认为尝试将 UITableView 对象传递给接受 BadgedCell 的配置方法。有什么想法如何解决这个问题吗？

cell.textLabel.text = [listOfItems objectAtIndex:indexPath.row];
cell.detailTextLabel.text = [listOfItems objectAtIndex:indexPath.row];
}
else
{
cell.textLabel.font = [UIFont fontWithName:@"Helvetica-Bold" size:16];
cell.textLabel.text = [[self.muscleArray objectAtIndex:indexPath.row]objectForKey:@"muscleName"];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
}
I'm using the new iOS5 TableView style code, but I seem to get a problem. It crashes whenever the searching = true function is called. I think it is triyng to pass the UITableView Object to the configure method with accepts the BadgedCell. Any ideas how to fix this?

您将 listOfItems 字典作为字符串传递到单元格：
如果您使用此：
我知道 listOfItems 包含许多字典。
因此，当您调用时：
您基本上是在尝试将字典分配给单元格标签。这就是为什么 Xcode 告诉你 [__NSCFDictionary isEqualToString:]。
尝试删除这些行。
You are passing the listOfItems dictionary as a string to the cell:
If you used this:
I understand that listOfItems contains many dictionaries.
So when you call:
You are basically trying to assign a dictionary to a cell label. thats why Xcode is telling you that [__NSCFDictionary isEqualToString:].
try to remove those lines.
您需要从配置方法中删除这两行，因为如果如前面三行所暗示的那样，您的“listOfItems”是一个字典列表，那么您尝试将字典设置为 textLabel 的文本字段，这将导致所有各种各样的问题。
You need to remove these two lines from inside your configure method, because if as the preceding three lines imply, your 'listOfItems' is a list of dictionaries then you are trying to set a dictionary as the text field of a textLabel which will cause all sorts of problems.
