ios - AFNetworking-可达性始终返回-1

Question

我使用最新的AFNetworking来源，可访问性对我而言不起作用，它永远不会触发可访问性块，并且[httpClient networkReachabilityStatus]始终返回-1。 SystemConfiguration / SystemConfiguration.h包含在.pch中

执行startMonitoringNetworkReachability(在AFHTTPClient中)。

iPhone 4，iOS 6.1

AFHTTPClient *httpClient = [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:URL]];

[httpClient setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {

    NSLog(@"Internet status changed");
    NSLog(@"%d", status);
}];

NSMutableURLRequest *request = [httpClient requestWithMethod:@"POST" path:method parameters:post];

NSLog(@"Network reach %d",[httpClient networkReachabilityStatus]);

AFJSONRequestOperation *operation = [self getOperationWithMethod:method withRequest:request andCallback:callback];

[operation start];

假设您正在使用ARC，则可能永远不会触发该块，因为一旦此方法完成，就会立即释放httpClient。

要解决此问题，您需要将httpClient创建为strong @property，例如:

@property (nonatomic, strong) AFHTTPClient *httpClient;
