对我从事的一个项目的所有 api 调用使用 LRResty。我注意到该项目经常泄漏内存，因此我得到了修复所有泄漏并提高当前应用程序稳定性的工作。

下面是场景： 整个项目在ARC下，但是LRResty是非arc的。视图控制器初始化将 self 作为委托传递的“CustomService”对象。CustomService 对象调用处理请求并返回响应的 LRResty 客户端。CustomService 具有属性“弱”的私有属性请求。

问题是： 当我运行仪器（在 iphone 或模拟器上）时，在属性请求属性为“弱”和“强”的两种情况下都会检测到泄漏。请求 (LRRestyRequest) 很弱（在这种情况下 customService dealloc 被调用）否则 customService 会陷入保留周期并且不会调用 dealloc。使用“弱”属性，泄漏是“malloc”，我无法识别来源，但是如果我将属性更改为“强”，“仪器”会在 initWithDelegate:self 和 [customService serviceScheduleRequest] 处显示泄漏，以及 customService 的 dealloc永远不会被调用。

如何使此代码无泄漏？我花了几个小时，我不知道。LRResty 框架是否有可能负责该内存问题？有人有使用这个框架的经验吗？

我的视图控制器

CustomService *customService = [[CustomService alloc] initWithDelegate:self]; 
[customService serviceScheduleRequest];

定制服务.h

@protocol CustomServiceDelegate;

@interface CustomService : Service <LRRestyClientResponseDelegate>

@property (nonatomic, weak) id<CustomServiceDelegate> delegate;

- (id) initWithDelegate:(id)aDelegate;
- (void)serviceScheduleRequest;

@end

@protocol CustomServiceDelegate <NSObject>

@optional

- (void) serviceScheduleRequestDidStart;
- (void) serviceScheduleRequestDidEndWithSuccessJSON:(id) JSON;
- (void) serviceScheduleRequestDidEndWithSuccess:(BOOL) status;
- (void) serviceScheduleRequestDidEndWithError:(NSError *)error;

@end

定制服务.m

@interface CustomService ()

@property (nonatomic, weak) LRRestyRequest *request;

@end

@implementation CustomService

@synthesize delegate=_delegate;

- (id) initWithDelegate:(id)aDelegate
{
    self = [super init];

    if (self)
    {
        _delegate = aDelegate;
    }
    return self;
}

- (void)serviceScheduleRequest
{
    NSMutableDictionary* parameters = [self getParams];

    self.private_request = [[LRResty client] post:@"http://mylink.com/apicall"
                                  payload:parameters
                                 delegate:self];
}


- (NSMutableDictionary*) getParams
{
    NSMutableDictionary* parameters = [super getParams];
    return parameters;
}


- (void)restClient:(LRRestyClient *)client receivedResponse:(LRRestyResponse *)response
{   
    [self.delegate callSomeMethod];
    // do something...
}

- (void) dealloc
{
    NSLog(@"\n\n\n\n dealloc gets called \n\n\n\n");
}

@end
