Question

我有一个UITableViewController，其中包含标题中的一个按钮，允许用户发布图片。按下按钮时，我以编程方式创建一个postButton，cancelButton和captionTextView -

UIButton *postButton = [[UIButton alloc]initWithFrame:CGRectMake(160, 0, 160, 50)];
postButton.tag = 8934;
postButton.backgroundColor = [UIColor blueColor];
[postButton setTitle:@"  Post" forState:UIControlStateNormal];
[postButton setImage:[UIImage imageNamed:@"addPicture.png"] forState:UIControlStateNormal];
[postButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
[postButton addTarget:self action:@selector(addImage) forControlEvents:UIControlEventTouchUpInside];

UIButton *cancelButton = [[UIButton alloc]initWithFrame:CGRectMake(0, 0, 160, 50)];
cancelButton.tag = 8934;
cancelButton.backgroundColor = [UIColor redColor];
[cancelButton setTitle:@"Cancel" forState:UIControlStateNormal];
[cancelButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
[cancelButton addTarget:self action:@selector(cancelImage) forControlEvents:UIControlEventTouchUpInside];

然后 - self.view addSubview:。用户按下帖子或取消按钮后 -

for (UIView *subview in [self.view subviews]) {
    if (subview.tag == 8934 || subview.tag == 2387) 
        [subview removeFromSuperview];
    }
}

删除按钮和textViews，但删除它们后，tableView向上移动，第一个单元格的一部分隐藏在naviagtionBar

下

Answer 1

我是傻瓜。在删除子视图而不是之前

之后调用navigationBar.hidden = false

在removeFromSuperview之后，第一个隐藏在NavigationBar下的tableView单元格
