是否可以禁用AFNetworking的所有缓存功能？

我正在构建自己的自定义缓存系统,并且不希望这也占用磁盘空间.

谢谢,阿什利

目前我正在编写一个应用程序(目标iOS 6,启用了ARC),它使用JSON进行数据传输,使用Core Data进行持久存储.JSON数据由PHP脚本通过json_encode从MySQL数据库生成.

我的问题是,对于某些表中的数据,以下代码失败:

- (NSDictionary *)executeFetch:(NSString *)query
{
    NSURL *requesturl = [NSURL URLWithString:[query stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

    NSError *dataError = nil;
    self.jsonData = [NSData dataWithContentsOfURL:requesturl options:kNilOptions error:&dataError];

    NSError *error = nil;
    self.jsonSerializationResult = [NSJSONSerialization JSONObjectWithData:self.jsonData options:NSJSONReadingMutableContainers|NSJSONReadingMutableLeaves error:&error];

    return self.jsonSerializationResult;

}

该程序总是在EXC_BAD_ACCESS错误的位置崩溃,它表示self.jsonSerializationResult和Instruments说有一个Zombie被检测到.我知道这意味着我发送消息的一些对象是零,但我无法找到如何解决它...这就是乐器所说的:

#   Address Category    Event Type  RefCt   Timestamp   Size    Responsible Library Responsible Caller
0   0xa1b8a70   CFString (mutable)  Malloc  1   00:01.603.081   32  Foundation  -[NSPlaceholderMutableString initWithBytesNoCopy:length:encoding:freeWhenDone:]

2   0xa1b8a70   CFString (mutable)  Zombie  -1  00:01.603.259   0 …

我正在使用AFNetworking在VolunteerMatch API上执行Web请求.当我执行请求时,我收到了200个代码,但是我没有收到回复.以下是典型的VolunteerMatch请求的样子:

GET /api/call?action=helloWorld&query=... HTTP/1.1
Host: www.volunteermatch.org
Accept-Charset: UTF-8
Content-Type: application/json
Authorization: WSSE profile="UsernameToken"
X-WSSE: UsernameToken Username="acme", PasswordDigest="quR/EWLAV4xLf9Zqyw4pDmfV9OY=",
Nonce="d36e316282959a9ed4c89851497a717f", Created="2003-12-15T14:43:07-0700"

这是扩展文档.

这是我用于提出请求的代码:

 // Create parameters
    NSDictionary* param = @{
                            @"action":@"helloWorld",
                            @"query":@"{\"name\":\"john\"}"
                            };

    // Create Manager
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    manager.responseSerializer = [AFJSONResponseSerializer serializer];
    manager.requestSerializer = [AFJSONRequestSerializer serializer];

    // Add Headers
    [manager.requestSerializer setValue:@"WWSE profile=\"UsernameToken\"" forHTTPHeaderField:@"Authorization"];
    [manager.requestSerializer setValue:[CocoaWSSE headerWithUsername:@"XXXXX" password:@"XXXXXXXXXXX"] forHTTPHeaderField:@"X-WSSE"];

    // Perform Request
    [manager GET:@"http://www.volunteermatch.org/api/call" parameters:param success:^(AFHTTPRequestOperation * _Nonnull operation, id  _Nonnull responseObject) {
        NSLog(@"HTTP Request URL: %@", [operation.request …
