我有一个应用程序,我在viewControllers与NSUserDefaults之间传递一些数据。NSUserDefaults setObject方法导致应用程序崩溃在ios8
这是我正在使用的代码。
[[NSUserDefaults standardUserDefaults]setObject:selectedLists forKey:UserID];
凡selectedLists是的NSMutableArray和用户ID是的NSString。
此代码正常工作,直到ios7和xCode5。
因为我更新了xCode6,现在我使用的是ios8,所以我的应用在xCode 6和ios 7.1上运行正常,但是当我在ios8设备中运行该应用时,该应用崩溃,出现以下错误。
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFNumber length]: unrecognized selector sent to instance 0x7a027060'
我只是不明白这里有什么问题。
如果有人遇到了ios8的这个问题,那么请帮助我。
在此先感谢。
的selectedLists
{
CardFace = Word;
ImportFlag = Import;
ListID = 1;
ListName = "Adjectives - Appearance";
QuizBy = Definition;
UserID = 1;
}
和用户ID值是1

编辑 在我的tableview的didselect方法...
UserID = [[users objectAtIndex:indexPath.row] valueForKey:@"UserID"];
其中用户是一个数组。
什么样的对象类型是selectedLists和UserID? – EridB 2014-10-09 07:45:05
我建议你设置一个异常断点或者检查堆栈跟踪来确认它实际上崩溃的那一行 – Paulw11 2014-10-09 07:46:16
另外,NSUserDefaults可能不是在对象之间传递数据的最有效的方式 - 'NSNotificationCenter'是更好的选择 – Paulw11 2014-10-09 08:00:29
