Afnetworking Framework default request type and response type are in JSON format, in special cases, when we use the string form, we will report 3840 error, how to solve it?

Parsing problems with JSON data format errorunescaped control character around character XXXXAnd the data couldn ' t be read because it isn ' t in the correct format.Error code is 3840When this happens, it is generally caused by the non-specification in the JSON data, the presence of an escape character in the JSON data may cause this, such as a/t/n/0, etc.Data is less canonical workaround: 1.

The positive gain is clear and narrow, this is what we often call the "throat". It should be said that the appropriate throat sound can increase the growth rate and sound sensitivity. However, if it passes through, it will make people feel unnatural. In terms of the voice of men and women, the gain near these fr
