ios – NSJSONSerialization错误？

试图调试过去10个小时的崩溃,最后我简化为这段代码：

NSError *error = nil;
NSData *data = [NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"payload" ofType:@"txt"]];
id obj = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&error];

使用NSZombieEnabled,这会使应用程序在第三行(解析发生时)崩溃,并记录：

*** -[CFString retain]: message sent to deallocated instance 0x758afa0

payload.txt的内容是：

[
   {

这只是一个2个字典的数组.我不知道是什么导致这个崩溃/这个JSON有什么问题.

UPDATE删除“is_subscribed”：数组中的第一个对象中的0将消除崩溃.

解决方法

看起来苹果在他们的类中错误地处理了这样的情况,因为你的崩溃而不是正常的零结果和错误变量的填充.您的json数据和简约代码是Apple通常需要的适当的错误报告.通过以下链接报告错误 – https://developer.apple.com/bugreporter/不要忘记在zip中附加项目作为它崩溃的证明.
