objective-c - RaptureXML怪异行为

我收到错误消息(它不会显示，只是崩溃退出应用程序，控制台上没有任何信息)
每当我从RXML的rootXML调用方法Iterate时，这种情况似乎都会发生:

-(void)valueSearch {
    //FIRST CONNECTION
    NSString *serverAddress = @"http://www.commix.com.br/clientes/grupoglobo/apple/valor.xml";
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:serverAddress]
                                                       cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData
                                                   timeoutInterval:10];
NSError *requestError;
    NSURLResponse *urlResponse = nil;

    response = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&requestError];

    //SECOND CONNECTION - Just an encapsulated form of the first, since i use it in other parts
    // of the code
    response = [self requestWithParameters:@"valor.xml"];

    //i just uncommented both. but actually only one (connection) runs.

    //Creation of the rooXML so i can grab the info i need
    RXMLElement *rootXML = [RXMLElement elementFromXMLData:response];
    //This array is where i'll keep the info from the files.
    //it`s deallocated at the end in dealloc
    searchResult = [[NSMutableArray alloc] init];

    //This is the culprit. Atleast it seems so, since putting NSLog before and after
    //revealed so.
    [rootXML iterate:@"valor" usingBlock: ^(RXMLElement *valor) {
        NSLog(@"valor: %@", [valor child:@"nome"].text);
        [searchResult addObject:[valor child:@"nome"].text];
    }];
}

问题是，当我注释requestWithParameters并使用普通的非封装样式(// FIRST CONNECTION)时，我不会出错。但是，如果我使用第二个，当程序到达[rootXML iterate: [...]]时，它将在没有警告的情况下崩溃。

使用RaptureXML:https://github.com/ZaBlanc/RaptureXML

它也发生在代码的另一部分:

-(void)vehicleSearch {

    NSString *path = [[NSBundle mainBundle] pathForResource:@"idArray" ofType:@"plist"];
    NSMutableArray *idArray = [[NSMutableArray alloc] initWithContentsOfFile:path];

    NSMutableString *serverAddress = (@"http://www.commix.com.br/clientes/grupoglobo/apple/modelo.php?marc=%@",[idArray objectAtIndex:0]);
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:serverAddress]
                                                       cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData
                                                   timeoutInterval:10];

NSError *requestError;
    NSURLResponse *urlResponse = nil;
    response = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&requestError];

    RXMLElement *rootXML = [RXMLElement elementFromXMLData:response];
    searchResult = [[NSMutableArray alloc] init];

    [rootXML iterate:@"modelo" usingBlock: ^(RXMLElement *modelo) {
        NSLog(@"modelo: %@", [modelo child:@"nome"].text);
        [searchResult addObject:[modelo child:@"nome"].text];
    }];

    [idArray release];
}

发生在同一行[rootXML iterate:]。

抱歉漏了东西，我没有经验(这就是为什么我在这里)，谢谢!

编辑:
真正的罪魁祸首是排队

NSMutableString *serverAddress = (@"http://www.commix.com.br/clientes/grupoglobo/apple/modelo.php?marc=%@",[idArray objectAtIndex:0]);

如果我直接传递参数，不带变量，它将起作用:

NSMutableString *serverAddress = (@"http://www.commix.com.br/clientes/grupoglobo/apple/modelo.php?marc=4");

它显示正确。

最佳答案

您确定,[idArray objectAtIndex:0]是NSString吗？
尝试使用

[NSString stringWithFormat:@"http://www.commix.com.br/clientes/grupoglobo/apple/modelo.php?marc=%@",[idArray objectAtIndex:0]];`

甚至

[NSString stringWithFormat:@"http://www.commix.com.br/clientes/grupoglobo/apple/modelo.php?marc=%@",[[idArray objectAtIndex:0]stringValue]];
