存入数据为nsnumber何nsstring异常

[HatsuneMikuV]

存入一个为@(0),@(1),@"1",@"0",都出现异常，

NSData * data = [NSJSONSerialization dataWithJSONObject:object options:0 error:&error];

===== po object
@"1"

===== po [object class]
error: Couldn't materialize: couldn't allocate a temporary region for the result: failed to send packet: 'M103d60620,8:0000000000000000'
error: errored out in DoExecute, couldn't PrepareToExecuteJITExpression

上面那四种 我都试过了 都崩溃 这个虽然是系统的方法 但是 应该是没问题的 现在问什么崩溃，还望解答
