一切都还可以，但不是 iOS 7.1.1
我不知道为什么。我尝试保存的对象是NSString或NSNumber（我检查了每个对象）
有人帮帮我！

=========================================
完成
好的，我找到了导致此错误的原因。在我尝试保存到NSUserDefault的对象中，有一些 NSNull 对象。 （您可以在我的帖子中使用关键字“NSNull”进行搜索）
在iOS 7.1.1下，iOS只显示了一条警告消息，但在iOS 7.1.1上， APP将崩溃
解
删除所有具有NSNull值的键。我正在使用AFNetworking，所以我写道：
+ (AFJSONResponseSerializer *)afJsonResponseserializer {
AFJSONResponseSerializer *ret = [AFJSONResponseSerializer serializer];
ret.removesKeysWithNullValues = YES;
return ret;
}
并在我需要的任何地方使用它来解析JSon

尝试仅添加此代码的一部分。您应该能够将其缩小到给出错误的行。
考虑到这一点，请记住，属性列表仅包含某些类型的数据：字典，数组，字符串，数字（整数和浮点数），日期，二进制数据和布尔值。例如，如果您的icon是UIImage，则不允许将其添加到plist中。
