Question

目前,我试图与一位网络服务器连接,并从中抽出一张桌子。我已将表格列入一个名为“数据表”的NSMutable阵列(全球)。然而,当我试图预示任何类型的行动时(图例:计数),它将给我一个EXC_BAD_ACCESS。 BTW I m使用ARC的X代码4.2,因此不是记忆管理问题。任何建议?

- (void)viewDidLoad
页: 1

    NSURL *url = [NSURL URLWithString: @"`url.com`"];
    NSData *jsonData =[NSData dataWithContentsOfURL:url];

    if(jsonData)

    页: 1
        xmlParser = [[NSXMLParser alloc] initWithData: jsonData];
        [xmlParser setDelegate: self];
        [xmlParser parse];
    iii
    NSLog(@"This is Number of elements: %@",[DataSet count]); ///<----EXC_BAD_ACCESS

 ..... //// default stuff//.....
    iii



- (撤销)parser:NSXMLParser *)parser doEndElement:NSString *)elementName namespaceURI:NSString *
页: 1


    if ([elementName isEqualToString:@"string"])
    页: 1

        /// puts the data into Array luckyNumbers
        NSError *error;
        SBJsonParser *json = [[SBJsonParser new] init];
        DataSet = [[NSMutableArray alloc] init];
        DataSet = [json objectWithString:soapResults error:&error];

      ///  NSLog(@"%@",DataSet); /// this works

I m not sure if I m suppose to but, I read that I should use Diagnostics, so I turned on NSZombie objects, Malloc guard, and Malloc Stack. They said I should type this into the gdb console info malloc-history (memorylocation)

However I don t know where to get the memory location of the problem. I would appreciate any help.

我无法做到这一点,因此,我尝试使用NSDictionary而不是NSArray,令人惊讶地工作! 这里,我更新了有关任何人的法典。

(void)viewDidLoad

页: 1

NSURL *url = [NSURL URLWithString: @"url.com"];
NSData *jsonData =[NSData dataWithContentsOfURL:url];
DataSet = [[NSDictionary alloc] init];

if(jsonData) 页: 1

    xmlParser = [[NSXMLParser alloc] initWithData: jsonData];
    [xmlParser setDelegate: self];
    [xmlParser setShouldResolveExternalEntities:YES];
    [xmlParser parse];
iii
NSLog(@"%@",DataSet.allKeys);

///// default stuff /// iii iii

if ([elementName isEqualToString:@"string"])

    //NSLog(@"%@",DataSet);
    DataSet = [soapResults JSONValue];
    NSLog(@"%@",DataSet);

Answer 1

(1) 在<条码>上,

DataSet = [[NSMutableArray alloc] init];

2) 在<代码>-(避免)parser:NSXMLParser * parser doEndElement:NSString *)elementName namespaceURI:String * 称, 姓名:

if ([elementName isEqualToString:@"string"])
{
    NSError *error;
    SBJsonParser *json = [[SBJsonParser new] init];
    [DataSet addObject:[json objectWithString:soapResults error:&error]];
    [json release];
}

3) 在<代码>DataSet后面所有平级物体都将储存

However I don t know where to get the memory location of the problem. I would appreciate any help.
