AFNetworking 代码块未执行

Question

我知道本网站不允许提出一般性问题 - 但我遇到的问题似乎与我的代码无关。这是我的代码前一分钟工作，下一分钟没有工作的计算机问题之一——我没有改变任何东西。我将发布我认为相关的代码 - 但我没有收到任何错误消息，无论是在我的调试控制台中的 XCode 还是在服务器端的 apache2 错误日志中。

可能相关的代码：

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

    UIImageWriteToSavedPhotosAlbum(info[UIImagePickerControllerOriginalImage], nil, nil, nil);

    NSString * uploadURL = @"http://192.168.1.4/upload.php";
    NSLog(@"uploadImageURL: %@", uploadURL);
    NSData *imageData = UIImageJPEGRepresentation(info[UIImagePickerControllerOriginalImage], 0.5);

    NSString *queryStringss = [NSString stringWithFormat:@"%@",uploadURL];
    queryStringss = [queryStringss stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    //manager.responseSerializer.acceptableContentTypes = nil;
    manager.responseSerializer=[AFJSONResponseSerializer serializerWithReadingOptions:NSJSONReadingAllowFragments];
    manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"];
    manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/plain"];

    NSUserDefaults *userdefaults = [NSUserDefaults standardUserDefaults];

    NSString *usernameEncoded = [[userdefaults objectForKey:@"pfuser"]stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

    NSDictionary *params = @{@"username": usernameEncoded, @"count": [userdefaults valueForKey:@"count"]};

    [manager POST:queryStringss parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
        [formData appendPartWithFileData:imageData name:@"file" fileName:@"file.jpeg" mimeType:@"image/jpeg"];
        }
          success:^(AFHTTPRequestOperation *operation, id responseObject) {
              NSLog(@"Success: %@ ***** %@", operation.responseString, responseObject);
              NSInteger count = [userdefaults integerForKey:@"count"];
              NSNumber *stored = [[NSNumber alloc] initWithInt:count];
              count++;
              [userdefaults setInteger:count forKey:@"count"];


              GMSMarker *marker3 = [[GMSMarker alloc] init];
              marker3.position = mapView_.myLocation.coordinate;
              marker3.title = [userdefaults objectForKey:@"pfuser"];
              marker3.map = mapView_;

              PFGeoPoint *point = [PFGeoPoint geoPointWithLatitude:mapView_.myLocation.coordinate.latitude longitude:mapView_.myLocation.coordinate.longitude];

              PFObject *pointstore = [PFObject objectWithClassName:@"MapPoints"];
              pointstore[@"title"] = [userdefaults objectForKey:@"pfuser"];
              pointstore[@"location"] = point;
              pointstore[@"count"] = stored;

              [pointstore saveEventually:^(BOOL succeeded, NSError *error) {

                  if (error) {
                      NSLog(@"Error");
                  }
                  else {
                      dispatch_async(dispatch_get_main_queue(), ^(void){
                          mapView_.settings.myLocationButton = YES;
                      });
                  }
              }];
          }
          failure:^(AFHTTPRequestOperation *operation, NSError *error) {
              NSLog(@"Error: %@ ***** %@", operation.responseString, error);
          }];

    [picker dismissViewControllerAnimated:YES completion:NULL];
}

上面是应该执行的代码。它似乎一直执行到[manager POST:queryStringss parameters:params...

我没有看到 NSLog 成功或失败消息，它只是停止运行...尽管应用程序没有崩溃...应用程序继续正常运行。

今天早上任何帮助将不胜感激（我愿意与知道他们在做什么的人一起工作，通过聊天或类似的方式）。提前致谢！

更新

PHP服务器端代码：

<?php

header("Content-Type: application/json");

$username = $_POST['username'];
$count = $_POST['count'];
$base64string = base64_encode(file_get_contents("images/".$username."/".$count."/".$username."file".$count.".jpeg"));
echo json_encode(array("image" => $base64string));

?>

更新

这是我现在声明manager 的地方：

#import "ViewController.h"
#import "SignUpController.h"
#import <Parse/Parse.h>
#import "AFHTTPRequestOperation.h"
#import "AFHTTPRequestOperationManager.h"
@import GoogleMaps;

typedef void (^CompletionHandlerType)();

@interface ViewController ()

@end


@implementation ViewController {
    GMSMapView *mapView_;
    BOOL firstLocationUpdate_;
    CLLocationManager *locationManager;
    UIImageView *image;
    UIButton *respondButton;
    AFHTTPRequestOperationManager *manager;
}

...

更新

在 TheEye 提供了一些出色的帮助后 - 我们发现，使用邮递员（Chrome 扩展程序），由于某种原因，该应用程序无法找到该页面……我收到了 404 响应（来自邮递员）。我还没有弄清楚为什么会这样，如果再提供帮助将不胜感激......但我可能不会马上回复，因为我很累。

Answer 1

愚蠢的防火墙一定已经开始随机阻止东西了。我禁用了防火墙，一切又开始工作了。
