Question

我能够从一个名为dogs的mysql中使用xml解析数组来启动和加载我的表，但当我点击该单元格时，它拒绝执行segue到下一个视图控制器（称为loadingViewController）来显示该行在标签中（与单元格中的结果相同）。我相信我已正确设置故事板。

ViewController.m

#import "ViewController.h"
#import "LoadingViewController.h"

@interface ViewController ()

@end

@implementation ViewController
- (void)dealloc
{
    [super dealloc];
    if ( dogs )
        [dogs release];
- (NSInteger)tableView:(UITableView *)table numberOfRowsInSection:(NSInteger)section {
    if ( dogs != NULL ) {
        return [dogs count];
    }
    return 0;
}

- (UITableViewCell *)tableView:(UITableView *)tv cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"MyIdentifier"];

    if (cell == nil)
    {
        cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"MyIdentifier"] autorelease];
    }

    NSDictionary *itemAtIndex = (NSDictionary *)[dogs objectAtIndex:indexPath.row];
    UILabel *newCellLabel = [cell textLabel];

    [newCellLabel setText:[itemAtIndex objectForKey:@"name"]];

    return cell;
}
-(method for calling to my mysql here. Below is how I successfully parse the returned results)
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict {

    if ( [elementName isEqualToString:@"dog"]) {
        [dogs addObject:[[NSDictionary alloc] initWithDictionary:attributeDict]];
    }
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{

    [self performSegueWithIdentifier:@"showDetail" sender:[NSString stringWith:dogs]];
}

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    if ([segue.identifier isEqualToString:@"showDetail"]) {
        NSIndexPath *indexPath = [self->tableView indexPathForSelectedRow];
        LoadingViewController *destViewController = segue.destinationViewController;
        destViewController.typeLabel = [dogs objectAtIndex:indexPath.row];
    }
}

LoadingViewController.h-只是标签的属性和nsstring dog的属性 LoadingViewController.m-刚刚合成的命令
