爲什麼AFNetworking在沒有互聯網連接的情況下成功運行？

Question

當我第一次完成這段代碼沒有互聯網連接時，它顯示警告應該如何。但是，當我首次成功完成互聯網連接並關閉互聯網連接後，所有下一次執行都將以相同的響應對象成功完成。沒有在設備上嘗試過，只有iOS模擬器。

NSString *string = @"https://money.yandex.ru/api/categories-list"; 
NSURL *url = [NSURL URLWithString:string]; 
NSURLRequest *request = [NSURLRequest requestWithURL:url]; 

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request]; 
operation.responseSerializer = [AFJSONResponseSerializer serializer]; 

[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { 
    [self deleteAllObjects]; 
    self.numberOfBranchObjects = 0; 
    for (NSString *key in (NSDictionary *)responseObject) { 
     [self insertNewObject:key fromSender:self]; 
    } 
} failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error Retrieving Weather" 
                 message:[error localizedDescription] 
                 delegate:nil 
               cancelButtonTitle:@"Ok" 
               otherButtonTitles:nil]; 
    [alertView show]; 
}]; 
[operation start]; 

它是在AFNetworking響應對象或smth其他任何緩存？

Answer 1

呀它的緩存，在這裏你去：

[operpation setCacheResponseBlock:^NSCachedURLResponse *(NSURLConnection *connection, NSCachedURLResponse *cachedResponse) { 
    return nil; 
}]; 

我建議你直接測試了互聯網連接，不過，請求之前。

你會做到這一點的把這個在您的視圖控制器的初始化部分：

- (BOOL)connected { 
    return [AFNetworkReachabilityManager sharedManager].reachable; 
}
