Ios UITableView中的问题

我有一个

UITableView

，它使用

NSMutableArray

来解析xml文件

问题：数据已添加到数组中，但在

UITableView

中不可见

子列表.h

@interface SubList:UIViewController <UITableViewDelegate, UITableViewDataSource>
{
    IBOutlet UITableView *List1;
    NSXMLParser *xmlparser;
    NSURLConnection *conn;
    NSMutableData *webdata;
    NSString *FolderID;
    NSMutableArray *info;
    NSMutableArray *SubFolderData;
}

@property(nonatomic,retain) NSMutableArray *info;
@property(nonatomic,retain) NSMutableArray *SubFolderData;
@property (nonatomic,retain)NSString *FolderID;
@property(nonatomic,weak)IBOutlet UITableView *List1;
@property (nonatomic,retain) NSString *theXML;

---

您未输入代理，因此尚未设置这些代理，请使用

[List1 setDelegate:self];
[List1 setDataSource:self];

在

视图中加载

在界面生成器中选择表视图
选择连接检查器
连接数据源并将其委托给文件所有者

您的表视图连接应如下图所示


Add还检查在调用表视图委托之前是否添加了数组。
嗨，RANA，我们不知道您是如何进行解析的，因为您没有发布任何解析器方法。但根据你的代码，我得到了一些

此[parserObjForData1 UserXMLParser1:webdata]的返回类型；我说的对吗

如果我猜对了，试试这个

SubListParser*parserObjForData1=[[SubListParser alloc]init]

子文件夹数据=[[NSMutableArray alloc]initWithArray:[parserObjForData1 UserXMLParser1:webdata]]

而不是

 SubListParser *parserObjForData1=[[SubListParser alloc]init];
    SubFolderData=[[[NSMutableArray alloc]init];
    SubFolderData=[parserObjForData1 UserXMLParser1:webdata];

我希望它能对您有所帮助。
这是sublistparser.m文件

#import "SubListParser.h"
 #import "DocumentManagementAppDelegate.h"

 @implementation SubListParser
  @synthesize mParserArray,ID,URL,SubjectType,Name;
  static int count = 1;


   -(NSMutableArray *)UserXMLParser1:(NSData *)WebDataRecieved1{

NSXMLParser *xmlparser1=[[NSXMLParser alloc]initWithData:WebDataRecieved1];
[xmlparser1 setDelegate:self];
BOOL success=[xmlparser1 parse];
NSLog(@"%i",success);
return listset1;

  }
   - (void)parser:(NSXMLParser *)parser parseErrorOccurred:(NSError *)parseError {
NSLog(@"NSXMLParser ERROR: %@ - %@",  [parseError localizedDescription], [parseError   localizedFailureReason]);
 }

  - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName 
   namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName 
   attributes:(NSDictionary *)attributeDict 
 {  
currentElementValue =[elementName copy];
if([elementName isEqualToString:@"FileFolderDetails"]){
    item=[[NSMutableDictionary alloc]init];
   Name=[[NSMutableString alloc]init];
    SubjectType=[[NSMutableString alloc]init];
    URL=[[NSMutableString alloc]init];
   // NSLog(@"%@",Name);
}


//if ([elementName isEqualToString:@"FileFolderDetails"]) {
//  NSLog(@"Inside FolderName");
  //  SUBLIST=[[SubListParser alloc]init];
  //  SUBLIST=[attributeDict objectForKey:@"Name"]; 

//}
 }

 - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{
//NSLog(@"%@",string);
if(count){
    listset1=[[NSMutableArray alloc]initWithCapacity:20];
    count=0;
    Urlarray = [[NSMutableArray alloc]initWithCapacity:20];
}


if ([currentElementValue isEqualToString:@"Name"]) {
    [Name appendString:string];
    [listset1 addObject:[NSString stringWithFormat:@"%@",Name]];
        //    NSLog(@"%@",listset1);
}

if ([currentElementValue isEqualToString:@"URL"]) {
    [URL appendString:string];
    [Urlarray addObject:[NSString stringWithFormat:@"%@",URL]];
    NSLog(@"Url Array :%@",Urlarray);

}


 }
  - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName;
{
if([elementName isEqualToString:@"FileFolderDetails"]){
[item setObject:Name forKey:@"Name"];
[item setObject:SubjectType forKey:@"Type"];
[item setObject:URL forKey:@"URL"];
[users addObject:item];
}


}

1.检查您的代理是否已设置。2.如果它们被调用.in.h，您说过要用conform to delegate编译这个类。但是您需要通过拖放或[tv setDelegate:self]etcin viewDidLoad方法设置在所有tableview委托方法中编写一个nslog，并检查它是否打印出来。发布一些相关代码。i、 e.XML解析代码，您正在填充
数据源
数组。我以前做过，但它不起作用，我又做了一次，但它仍然不起作用。@RANA:您是否已钩住列表1以更正tableView。并使用
@
来推荐我，这样我就可以得到通知。我没有名声来标记你：我在我的xib文件中有相同的连接在NumberOfRowsin处放置一个断点，记录[SubFolderData count]/2，在此处发布日志消息……嗨，拉娜，如果你仔细观察上述代码，你可能会发现问题，请参阅下面的代码-（void）解析器：（NSXMLParser*）解析器查找字符：（NSString*）字符串{//NSLog（@“%@”，string）；if（count）{listset1=[[NSMutableArray alloc]initWithCapacity:20]；count=0；Urlarray=[[NSMutableArray alloc]initWithCapacity:20]；}if（[currentElementValue IsequalString:@“Name”]）{[Name appendString]；[listset1 addObject:[NSString stringWithFormat:@“%@”，Name]]；//NSLog（@“%@”，listset1）；}如果你看到Find characters方法，你在里面初始化listset1数组，很明显，数组会不断变清晰，所以即使你在数组中添加了任何东西，它也不会被添加。正因为如此，你不能在tableview中获取数据。现在为了避免这种情况，你必须在UserXMLPa中初始化listset1数组rser1方法不在foundcharacters方法中。请提前感谢。
