Ios _NSArrayM isEqualToString:：发送到实例0x8d70f00的选择器无法识别

我有一个带有with key及其值的NSDictionary，我希望将其填充到tableview中，但我遇到如下错误：

  -[__NSArrayM isEqualToString:]: unrecognized selector sent to instance 0x8f8e4d0
2014-08-13 13:29:45.357 SotaApp[1602:60b] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayM isEqualToString:]: unrecognized selector sent to instance 0x8f8e4d0'  

activity =     (
    "0Pharmacology.html"
);
acute =     (
    "0Pharmacology.html"
);
adenosine =     (
    "0Guidelines Precautions.html"
);
administration =     (
    "0Guidelines Precautions.html"
);
aneurysm =     (
    "0Dilution for Infusion.html"
);
arrhythmias =     (
    "0Guidelines Precautions.html"
);
artery =     (
    "0Dilution for Infusion.html"
);
asthma =     (
    "0Guidelines Precautions.html"
);
atrium =     (
    "0Dosing.html"
);

我尝试的是：

NSString *value = [filteredDictionaryValues valueForKey:[filteredDictionaryValues.allKeys objectAtIndex:indexPath.row]];

cell.textLabel.text =[filteredDictionaryValues.allKeys objectAtIndex:indexPath.row];
cell.detailTextLabel.text = value;

请告诉我有什么问题， 多谢各位

编辑 字典如下所示：

我已从搜索方法中筛选词典：

-(void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText

{

---

}

当您调用

[FilterAdditionaryValues valueForKey:[FilterAdditionaryValues.allKeys objectAtIndex:indexPath.row]

时，返回的值是带有1个string对象的NSArray（

NSArray*数组=[FilterAdditionaryValues valueForKey:[FilterAdditionaryValues.allKeys ObjectAtIndeXPath.row]；NSString*string=[array firstObject]；

）。如果可以，您应该更改字典的填充方式（而不是只使用一个对象的数组）。如果没有，请使用返回数组中的firstObject。

您可以添加填充字典的方式吗？我的字典是FilterAddictionAryValues。我已经添加了：您显示的代码没有产生任何问题。您在代码中使用的

isEqualToString

或请再次检查异常日志并跟踪第n行umber.@Rajeev我想问的是，你能展示一下你是如何创建这本字典的以及字典里有什么吗。@Rajeev问题是，你的字典将键映射到数组，每个数组都包含一个字符串（这可能不是你想要做的）.那么，你能分享一些代码来展示你是如何创建这个dict的吗？非常感谢你…你太棒了
