我不能導航到（didSelectedRowAtIndexPath）另一種觀點

Question

當我行點擊導航到其他視圖它給我的崩潰

"Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<detailInfo 0x6b503d0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key lblText.' 
*** First throw call stack: 
" 

這是我的代碼：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    _vcontroler = [ urls objectAtIndex:indexPath.row]; 

    if (!self.detailViewController) 
    { 
     self.detailViewController = [[[detailInfo alloc] initWithNibName:@"detailInfo" bundle:nil] autorelease]; 

    } 
     detailViewController.vcontroler =_vcontroler; 

    [self.navigationController pushViewController:self.detailViewController animated:YES]; 

    [detailViewController release]; 
}

問題在於你從視圖的框架中刪除了一個圖形對象，而沒有刪除出口連接。選擇您的視圖控制器的.xib，然後選擇File's Owner（左鍵單擊它）並刪除lblText對象的插座連接。編譯&運行。應該沒問題。
