NSDictonnary allValues SIGABRT

Question

我在这一行得到一个SIGABRT

NSArray *array = [dict allValues];

我通过在之前放置一个NSLog来检查我的字典，它看起来没问题

NSLog(@"dict value : %@",dict);

输出：

（         {         “category_id”= 1;         content =（                         {                 copyright = copyright;                 description =“”;                 endDate =“18-12-2011”;  .....

2011-08-05 16:02:44.576 xxx[7578:b603] -[__NSArrayM allValues]: unrecognized selector sent to    instance 0x4e36a10
2011-08-05 16:02:44.578 xxxx[7578:b603] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayM allValues]: unrecognized selector sent to instance 0x4e36a10'

有什么想法吗？
