尝试使用 AFNetworkings ReachabilityStatusChanged 但获取

“HTTPCLIENT 的可见@interface 声明了选择器 setReachabilityStatusChangeBlock”

但是HttpClient有那个功能。有人知道为什么会这样吗？

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

    NSLog(@"%d", status);

}];

///更新///////////

这是我的 .pch 文件

#ifdef __OBJC__
#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>
#import <CoreData/CoreData.h>
#import "NSDate+Helper.h"
#import "NSEntityDescription+RKAdditions.h"
#import "UIAlertView+MKBlockAdditions.h"

#endif

最佳答案

移动

#import <SystemConfiguration/SystemConfiguration.h>

在这一行之后:

#ifdef __OBJC__

关于ios - HttpClient setReachabilityStatusChangedBlock 声明没有接口(interface)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/17334237/
