为什么第二次崩溃？

Question

嘿伙计们,我是Objective-C的新手,而且我正在创建一个应用程序,当你点击一个表格单元格时,它会按照它应该做的,但是当你第二次回到并点击单元格时,它就会与"EXC_BAD_ACCESS"崩溃.你能告诉我它意味着什么,为什么它只是第二次崩溃,我怎么能解决它？我很确定它在这个功能中:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
// Navigation logic may go here. Create and push another view controller.

    RaceData * data = [self.units objectAtIndex:indexPath.row];
    ProtossInfo * info = [[ProtossInfo alloc] initWithNibName:@"ProtossInfo" bundle:nil];

     // ...
     // Pass the selected object to the new view controller.
    [self.navigationController pushViewController:info animated:YES];

    info.title = data.titler;
    info.minerals.text = data.min;
    info.vespene.text = data.vesp;
    info.supply.text = data.sup;
    info.portrait.image = data.porty;

    [info release];
    [data release];

}  

Answer 1

你发布了data,你没有发布retain.
