I tested your code with Xcode, and found an error:

Initializing 'JsonValue' with an expression of incompatible type 'JsonValue *'; dereference with *

Check the API of JsonValue:

JsonValue* (*Parse) (const char* jsonString);

So I changed the code to:

JsonValue* value = AJson->Parse(jstr);

But got a runtime error:

Invalid json value type, error char = :

Now the problem is that the string is not a valid json format：

char* jstr = ":#@$^^&^(";
