Question

如何在表格视图单元格中显示arrayData？我想将表格视图单元格的标签文本设置为解析数据中的“ename”。请帮帮我。

先谢谢。

- (void)viewDidLoad {

    NSString *url = [NSString stringWithFormat:@"http://mmabigshow.com/app/get_result_from_query.php?q=select * from event"];

    NSString *escapedUrl = [url stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; 

    [self performSelector:@selector(startParsing:) withObject:escapedUrl afterDelay:1.0];

    NSLog(@"View Did Load End");*/
     [super viewDidLoad];

}
- (void) startParsing: (NSString *) query{

    NSLog(@"Start Of Parsing");
    NSURL *xmlURL = [[NSURL alloc] initWithString:query];
    NSData *myData = [NSData dataWithContentsOfURL:xmlURL];
    NSString *myStr = [[NSString alloc] initWithData:myData encoding:NSWindowsCP1252StringEncoding];
    myStr = [myStr stringByReplacingOccurrencesOfString:@"encoding=\"windows-1252\"" withString:@""];
    NSData* aData = [myStr dataUsingEncoding:NSUTF8StringEncoding];

    rssParser = [[NSXMLParser alloc] initWithData:aData];
    [rssParser setDelegate:self];
    [rssParser setShouldProcessNamespaces:NO];
    [rssParser setShouldReportNamespacePrefixes:NO];
    [rssParser setShouldResolveExternalEntities:NO];    
    [rssParser parse];
    NSLog(@"End of Parsing");

}

我相信你的问题是你并没有将dataArray称为self.dataArray，这可能导致你的程序无法正常工作。

然后通过

分配

cell.textLabel.text = [self.dataArray objectAtIndex:indexRow.row];

希望这有帮助

Apple的SeismicXML app就是这样做的。查看rootViewController的cellForRowAtIndexPath。

另外，请确保您的tableview在Interface Builder中正确设置了委托和数据源（如果您选择使用它）。
