AFNetworking 代码给我内存泄漏

Question

@implementation GetData

static NSString *string = @"https://afternoon-springs-7986.herokuapp.com/";
static NSString *baseStr = @"https://afternoon-springs-7986.herokuapp.com/updateInformation";    

-(void) postEventInfo: (NSDictionary *) eventInfoObject


    {
        NSURL *url = [NSURL URLWithString:string];  // 6.5%
       // NSURL *baseURL = [NSURL URLWithString:@"http://localhost:5000/"];

        UIWindow *window = [[UIApplication sharedApplication] keyWindow];
        UIView *topView = window.rootViewController.view;

        self.manager = [[AFHTTPSessionManager alloc] initWithBaseURL:url]; // 71%
        self.manager.requestSerializer = [AFJSONRequestSerializer serializer];
        self.manager.responseSerializer = [AFJSONResponseSerializer serializer]; // 9.7%

        [self.manager POST:@"/addEvent/" parameters:eventInfoObject success:^(NSURLSessionDataTask *task, id responseObject) { // 12.9%

        [FVCustomAlertView showDefaultDoneAlertOnView:topView withTitle:@"Klart!"];

        } failure:^(NSURLSessionDataTask *task, NSError *error) {

        [FVCustomAlertView showDefaultErrorAlertOnView:topView withTitle:@"Ett fel uppstod, försök igen!"];
        }];
    }

我收到上面这段代码的内存泄漏。如您所见，我评论的百分比与泄漏仪器所做的相同。我正在运行 Xcode 6，并在我的 iPhone 设备 5s IOS 7.1.1 上进行了测试

这里是如何泄漏工具的屏幕截图。 https://www.dropbox.com/s/beh4no79wgk54bm/Screen%20Shot%202015-03-12%20at%2013.09.53.png?dl=0

每次调用“postEventInfo”时，都会创建一个AFHTTPSessionManager 对象。

如果您使用 ARC，这应该意味着旧对象被释放（即不是这样的问题）。但为了获得最佳实践，您应该这样做：

// set self.manager only if it hasn't been created yet
if(!self.manager)
{
    self.manager = [[AFHTTPSessionManager alloc] initWithBaseURL:url]; // 71%
    self.manager.requestSerializer = [AFJSONRequestSerializer serializer];
    self.manager.responseSerializer = [AFJSONResponseSerializer serializer]; // 9.7%
}
