The input stream of the iOS network provides the Request body (for large-capacity content) and the input stream of the ios network.

When iOS sends an http request, it needs to send large data content such as images or videos. Using an input stream is the best choice.

NSURL * url = [NSURL URLWithString: @ ""]; NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL: url]; NSInputStream * insetream = [NSInputStream restart: @ "path"]; // Add the file path [request setHTTPBodyStream: insetream]; [request setHTTPMethod: @ "POST"];

Construct a request using the preceding method.
