I am relatively new to development on iOS and trying to get familiarized with RestKit, so bear with me if I am missing something obvious.

我们正在开发一个SOS 5号申请,接收和绘制JSON的物体地图(如果情况允许,ARC即可)。 在寻找复习辅导时,我来过,这是一份。 但是,该样本代码的简化版本(在“KRKClient”栏中,有一部)有以下错误:

2012-01-14 22:15:55.124 Test_StaticLibInApp[789:707] *** Assertion failure in -[RKRequestQueue removeRequest:decrementCounter:], /Users/m/Documents/devel/ios/RestKit/Code/Network/RKRequestQueue.m:350
2012-01-14 22:15:55.129 Test_StaticLibInApp[789:707] *** Terminating app due to uncaught exception  NSInternalInconsistencyException , reason:  Attempted to decrement loading count below zero 

确切地说,我曾尝试过:

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    RKClient *client = [RKClient clientWithBaseURL:@"some_url"];
    RKLogConfigureByName("RestKit/Network", RKLogLevelTrace);

    NSDictionary *queryParameters = [NSDictionary dictionaryWithObjectsAndKeys:nil];
    NSString *getResourcePath = RKPathAppendQueryParams(@"some_url_segment", queryParameters);
    RKRequest *request = [client get:getResourcePath delegate:self];
    [request sendAsynchronously];
}

- (void)request:(RKRequest *)request didLoadResponse:(RKResponse *)response
{
    id jsonParser = [[RKParserRegistry sharedRegistry] parserForMIMEType:RKMIMETypeJSON];
    NSError *error = nil;
    id parsedResponse = [jsonParser objectFromString:[response bodyAsString] error:&error];
    if (error == nil)
    {
        NSLog(@"GET returned with HTTP Code %d and parsedContent: %@", [response statusCode], parsedResponse);
    }
    else
    {
        NSLog(@"Error: %@", error);
    }
}

- (void)request:(RKRequest *)request didFailLoadWithError:(NSError *)error
{
    NSLog(@"Failure of GET with error %@.", error);
}

Here s the trace output:

这一错误是否与正在汇编的ARC有关? 关于休息室安装,我从盖特总务科取到档案,遵循安装指示,不改变任何环境。

Thanks in advance for any help.
