我似乎遇到了一个我无法弄清楚的简单问题。如图所示，我NSOperation创建了一个对象，并尝试将其设置为NSMutableDictionary将“null”设置为键而不是对象的NSOperation对象。
keyToOperationDictionary是通过延迟加载创建的，代码如下：
@synthesize keyToOperationDictionary = keyToOperationDictionary_;
-(NSMutableDictionary*)keyToOperationDictionary
{
if (nil==keyToOperationDictionary_)
{
keyToOperationDictionary_ = [[NSMutableDictionary alloc] init];
}
return keyToOperationDictionary_;
}
我不知道这里还有什么问题。当我在调试控制台中打印对象时，它会向我显示该对象，但未将同一对象设置为字典。
任何帮助/建议都会有很大帮助！
PS：我之前忘了提到它有时有效，有时无效。我不知道为什么！
添加了详细信息：
CSStatisticsKey class:
