HttpClient setReachabilityStatusChangedBlock声明没有接口 [英] HttpClient setReachabilityStatusChangedBlock declares no interface

问题描述

尝试使用AFNetworkings ReachabilityStatusChanged但得到

Trying to use AFNetworkings ReachabilityStatusChanged but getting

HTTPCLIENT的不可见@interface声明了选择器setReachabilityStatusChangeBlock

"No visible @interface for HTTPCLIENT declares the selector setReachabilityStatusChangeBlock"

但是HttpClient有那个功能。有人知道为什么会这样吗？

But HttpClient has that function. Anyone know why this is happening?

AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:@"http://stat-api.herokuapp.com/"]];
[client setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status){

    NSLog(@"%d", status);

}];
