可能的重复:
发送到实例的选择器无法识别

谁能告诉我此错误代码中发生了什么?男人苹果很神秘。我刚刚通过 ObjectiveResource 调用了我知道没问题的数据。

Can anyone tell me what is going on in this error code? Man apple is cryptic. I have just made a call via ObjectiveResource to data I know is fine.

正如其他人指出的那样,NSDecimalNumber 不响应 allKeys 选择器,从而导致崩溃。

发生这种情况可能是因为 NSDictionary 的实例(预期的消息响应者)由于某种原因(缺少保留?)而被过早释放,并且它在内存中的地址被获取错误消息的 NSDecimalNumber 实例占用。

因此,要解决该问题,请尝试找到该消息行并检查该代码中的内存管理是否一切正常。

As others pointed NSDecimalNumber does not respond to allKeys selector and that causes a crash.

That may happen because the instance of NSDictionary, the intended message responder was prematurely deallocated for some reason (lack of retain?) and its address in memory got occupied by NSDecimalNumber instance that gets that wrong message.

So to fix that problem try locating the line that message and check if everything is ok with memory management in that code.

您在 NSDecimalNumber 上调用 allKeys 方法,并且 NSDecimalNumber 不能使用此方法,这就是您崩溃的原因。

使用 NSDictionaryNSMutableDictionary 调用 allKeys 方法。

因此,在获取此日志后输入 where ,您将在此处获得需要编辑代码的行号。

You calling allKeys method on NSDecimalNumber,and NSDecimalNumber can,t use this method thats why you having a crash.

allKeys method call with NSDictionary or NSMutableDictionary.

so type where after getting this log you get line number at there you need to edit the code.

NSDecimalNumber 不支持 allKeys 方法。

NSDecimalNumber does not support the method allKeys.
