ios - FTP、Blackraccoon 内存泄漏

Question

我正在使用 Blackraccoon FTP 客户端进行 FTP 操作，使用 ARC。但我的仪器出现泄漏。
但是这里的示例应用程序没有泄漏是我的代码

 BRRequestCreateDirectory  *createEventDir = [BRRequestCreateDirectory initWithDelegate:nil];
//NSString *EventCode = [[NSUserDefaults standardUserDefaults] stringForKey:kEventCodeKey];
createEventDir.path = @"/12341234";
createEventDir.hostname = @"media.example.com/httpdocs/events/";
createEventDir.username = @"badboy";
createEventDir.password = @"hai!";
createEventDir.tag = 103;
[createEventDir start];
createEventDir = nil;

来自 FTP 客户端的示例代码 Blackraccoon FTP client

仪器中出现泄漏，但我使用的是 ARC谁能帮我解决这个问题..

Answer 1

我移植并大量修改了 BlackRaccoon。它旨在使用委托(delegate)。换句话说，代表是必需的。

BRRequestCreateDirectory  *createEventDir = [BRRequestCreateDirectory      initWithDelegate:nil];
//NSString *EventCode = [[NSUserDefaults standardUserDefaults]     stringForKey:kEventCodeKey];
createEventDir.path = @"/12341234";
createEventDir.hostname = @"media.example.com/httpdocs/events/";
createEventDir.username = @"badboy";
createEventDir.password = @"hai!";
createEventDir.tag = 103;
[createEventDir start];
createEventDir = nil;

不正确。它开始了很多事情，然后删除了对象—— Action 是未定义的。

相反，您需要我提供的代码中指示的内容(不会泄漏)。

首先，使用ftp的类需要有BRRequestDelegate来指明委托(delegate)协议(protocol)。

- (IBAction) createDirectory:(id)sender
{
    //----- createEventDir must be a variable in your class...

    createEventDir = [BRRequestCreateDirectory initWithDelegate: self];

    createEventDir.path = @"/12341234;
    createEventDir.hostname = @"media.example.com/httpdocs/events/";
    createEventDir.username = @"badboy";
    createEventDir.password = @"hai!";
    [createEventDir start];

    //----- createEventDir MUST NOT BE DELETED OR SET TO NIL HERE
}

然后你必须有两个代表(至少):

-(void) requestCompleted: (BRRequest *) request
{
    //----- handle Create Directory
    if (request == createEventDir)
    {
        NSLog(@"%@ completed!", request);
        //----- everything is done, NOW you can set it to nil
        createEventDir = nil;
    }
}  

-(void) requestFailed: (BRRequest *) request
{
    if (request == createEventDir)
    {
        NSLog(@"%@", request.error.message);
        //----- everything is done, NOW you can set it to nil
        createEventDir = nil;
    }
}

如果您回头看看我的测试代码，您就会明白事情是如何运作的。如果您仍有问题，请在 http://github.com/lloydsargent/BlackRaccoon 上发布问题

希望这能让您解决问题。
