当使用NSUserDefault直接存储Facebook的token对象时，会报错（Attempt to set a non-property-list object as an NSUserDefaults），因为NSUserDefault无法直接存储自定义对象。

解决方法为：

1、存储对象

**\[cpp\]** [view plain][] [copy][view plain]

1.  NSUserDefaults \*userDefaults = \[NSUserDefaults standardUserDefaults\];
2.  NSData \*tokenObject = \[NSKeyedArchiver archivedDataWithRootObject:token\];
3.  \[userDefaults setObject:tokenObject forKey:@"FBToken"\];
4.   \[userDefaults synchronize\];
5.

2、读取对象

**\[cpp\]** [view plain][] [copy][view plain]

1.  NSUserDefaults \*userDefaults = \[NSUserDefaults standardUserDefaults\];
2.  NSData \*tokenObject = \[userDefaults objectForKey:@"FBToken"\];
3.  FBSDKAccessToken \* token = \[NSKeyedUnarchiver unarchiveObjectWithData:tokenObject\];
4.
