请原谅我问这个愚蠢的问题,但是有人可以告诉我 NSURLResponse 和 NSHTTPURLResponse 之间有什么区别

最佳答案

"NSURLResponse declares the programmatic interface for an object that accesses the response returned by an NSURLRequest instance.

NSURLResponse encapsulates the metadata associated with a URL load in a manner independent of protocol and URL scheme.

An NSHTTPURLResponse object represents a response to an HTTP URL load request. It’s a subclass of NSURLResponse that provides methods for accessing information specific to HTTP protocol responses." *
