Is setting the Files Owner to nil. So you can't wire any of your labels to that. Instead, make sure the class of the cell is <code>ReservationCell</code> and its outlets are connected to the labels.

blocks|key|2073832|text|当我在storyboard中复制了一个原型单元并删除了单元中的一个插座时，我遇到了这个问题。它留下了对插座的引用，但没有连接到任何东西。右键单击原型单元并查找其中一个黄色警告标记。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2073833|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I had this problem when I had duplicated a prototype cell in storyboard and deleted one of the outlets in the cell. It left a reference to the outlet but not connected to anything. Right-click on the prototype cell and look for one of those yellow warning markers.

blocks|key|2073858|text|当在File的接口构建器中，将CustomCell的Owner自定义类设置为您的CustomCell类时，就会发生此问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2073859|应始终将视图文件的所有者自定义类设置为您的CustomCell类。|2073860|此外，您还需要使用您的表视图单元格的Nib名称初始化它。|2073861|示例(NotificationCell是我的自定义单元格类)：http://i42.tinypic.com/29pw0a8.png|offset|length|2073862|entityMap|0|LINK|mutability|MUTABLE|url|http://i42.tinypic.com/29pw0a8.png^0|0|0|0|V|Y|0|0^^$0|@$1|2|3|4|5|6|7|R|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|S|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|T|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|U|8|@]|9|@$H|V|I|W|1|X]]|A|$]]|$1|J|3|-4|5|6|7|Y|8|@]|9|@]|A|$]]]|K|$L|$5|M|N|O|A|$P|Q]]]]

This problem happen when in the interface builder for the CustomCell nib, the File's Owner custom class is set to your CustomCell class.

<ol>
<li>File's owner custom class should be set always UITableViewCell.</li>
<li>Table view object custom class should be set to your CustomCell class.</li>
</ol>

Also you need to initialize it with Nib name of your tableview cell.

Example (NotificationCell is my custom cell class):
<a href="http://i42.tinypic.com/29pw0a8.png" rel="noreferrer">http://i42.tinypic.com/29pw0a8.png</a>

blocks|key|3513313|text|对于像我这样已经接触到这个主题但不能找到解决方案的人，这里是这个问题的快速解决方案：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3513314|在界面构建器中，当您应该从单元格视图中链接IBOutlets时，您却链接了来自文件所有者的文件。这就是你得到这些错误的原因。|3513315|祝你好运！|3513316|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

For someone, who already reached to this thread and not able to figure out the solution like me, here is the quick solution to this problem:

In interface builder you linked your IBOutlets from File's Owner when you should link them from the cell view. This is why you are getting the errors.

Good Luck!!!

blocks|key|3513353|text|我的异常是'NSUnknownKeyException'，原因是：‘setValue:forUndefinedKey:：这个类不符合键的键值编码(以及我在CustomCell上有的名称标签，只有当我在CustomCell中添加一些东西时才会出现这个错误，例如label)|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3513354|解决方案问题我的朋友给了我很好的建议将MyCustomCell.m添加到ProjectSettings+->构建阶段->添加MyCustomCell.m文件|offset|length|style|BOLD|3513355|entityMap^0|0|10|16|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@$D|L|E|M|F|G]]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

My exception was 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key (and name label which I had on the CustomCell, I got this error only when I added something in CustomCell e.g. label)

Solution problem my friend gave me great advice add MyCustomCell.m add to the ProjectSettings -> Build Phases -> add MyCustomCell.m file

blocks|key|5113396|text|在我的例子中，我已经将单元格的接口添加到了头文件中，但是在.m文件中没有实现。只需将类的空实现(如下所示)添加到.m文件中即可解决此问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5113397|@implementation+myTableViewCell

In my case I had added the interface for the cell to the header file but did not have an implementation in the .m file. Simply adding an empty implementation (as below) for the class to the .m file fixed the problem.

<pre><code>@implementation myTableViewCell
@end
</code></pre>

Surprised this has not been listed as an answer as this has bitten me several times in the past. Hope this helps someone!

I am getting this error:

<pre><code> *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[&lt;NSObject 0x5a37750&gt; setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key destination.'
</code></pre>

Following is the code:

<pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
 static NSString *CellIdentifier = @"ReservationCell";

 ReservationCell *cell = (ReservationCell*) [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
 if (cell == nil) {
 NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"ReservationCell" owner:nil options:nil];
 for (id currentObject in topLevelObjects){
 if ([currentObject isKindOfClass:[UITableViewCell class]]){
 cell = (ReservationCell *) currentObject;
 break;
 }
 }
 }


 //cell.origin.text = [[data objectAtIndex:indexPath.row] origin];
 //cell.destination.text = [[data objectAtIndex:indexPath.row] destination]; 
 //cell.time_range.text = [[data objectAtIndex:indexPath.row] time_range]; 

 return cell;
}
</code></pre>

Here is the ReservationCell.h

<pre><code>@interface ReservationCell : UITableViewCell {
 UILabel * origin;
 UILabel * destination;
 UILabel * time_range;
}

@property (nonatomic, retain) IBOutlet UILabel * origin;
@property (nonatomic, retain) IBOutlet UILabel * destination;
@property (nonatomic, retain) IBOutlet UILabel * time_range;

@end
</code></pre>

Here's how I wired it up:
