iOS GCDAsyncSocket sending data sets cache size?

Question

iOS GCDAsyncSocket sends data and sets the cache size. Every time I send a picture to the server, the remaining part is not sent out. I have to wait until I send a piece of data before sending out the rest of the previous one. This happens every time. This is because GCDAsyncSocket sets the cache size incorrectly. ? How to set cache size?

Answer 1

No matter how big the picture is, it is divided into two parts?

GCDAsyncSocket does not have the settings you mentioned. Socket transmission is limited by MTU. This is normal. https://zh.wikipedia.org/wiki...
