我正在尝试使用下面的代码将会话保存到NSUserDefaults，并且出于某种原因这样做会导致我的应用程序崩溃并出现以下错误。

知道为什么吗？

谢谢！

Answer 1

“知道为什么吗？”是：

[[DIOSSession sharedSession] user]

我不知道NSArray是什么，但只有NSDictionary，NSString，NSData，NSNumber，NSDate和{ {1}}可以存储。

所以我想这就是原因。

Answer 2

请尝试这个

用于设置对象：

NSData *yourData = [NSKeyedArchiver archivedDataWithRootObject:[[DIOSSession sharedSession] user]];
[[NSUserDefaults standardUserDefaults] setObject:yourData forKey:@"yourKey"];
[[NSUserDefaults standardUserDefaults] synchronize];

获取对象：

NSData *data = [[NSUserDefaults standardUserDefaults] objectForKey:@"yourKey"];
    DIOSSession *object = [NSKeyedUnarchiver unarchiveObjectWithData:data];

保存到NSUserDefaults崩溃应用程序？
