iphone - 当我的 viewDidDisappear 时，我尝试释放我的表格。当我回到视野时仍然在那里

Question

我像这样声明我的表:

    CGRect cgRct = CGRectMake(5, 5, 310, 363);
videoTable = [[UITableView alloc] initWithFrame:cgRct style:UITableViewStylePlain];
videoTable.backgroundColor = [UIColor clearColor];
videoTable.separatorColor = [UIColor whiteColor];
videoTable.separatorStyle = UITableViewCellSeparatorStyleSingleLine;
videoTable.dataSource = self;
videoTable.delegate = self;
videoTable.alwaysBounceVertical = NO;
videoTable.bounces = NO;
videoTable.allowsSelection = YES;
//self.videoTable.layer.zPosition = -1;
//table.dragging = NO;
[self.view addSubview:videoTable];

当我们离开 View 时，我会移除我的 table

-(void) viewDidDisappear:(BOOL)animated
{
[super viewDidDisappear:animated];
NSLog(@"*viewDidDisappear");
if (videoTable)
{
    NSLog(@"removing table");
    [videoTable removeFromSuperview];
    videoTable.delegate = nil;
    [videoTable release];
   // self.videoTable = nil;
}
}

当 View 再次加载时，没有表格的迹象，但是..它仍然在那里，因为

-(void) viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
[self populateFileList];

if (videoTable)
{
    NSLog(@"table still here");
}
else
{
    NSLog(@"No table");
}
}

有人能解释一下我错过了什么吗？我希望该表完全消失，这样我就可以分配一个新表。

非常感谢，-代码

释放表后需要将其赋值为nil，否则该变量仍然有值(对表对象的旧引用):

[videoTable release];
videoTable = nil;
