如何在UIScrollview中嵌入UITableView [英] How to embed a UITableView in a UIScrollview

问题描述

如何在UIViewController中执行以下操作（包含作为子视图的tableview）

How can I do the following in a UIViewController (containing a tableview as a subview)

我最初有一个UIViewController显示预览部分（UIView）

I initially have a UIViewController showing a preview section (UIView)

//Setup container for preview section
UIView *tempContainer = [[UIView alloc]initWithFrame:CGRectMake(0, 20, 320, 100)];
self.preview_answer_container = tempContainer;
self.preview_answer_container.backgroundColor = [UIColor clearColor];
[tempContainer release];
[self.view addSubview:self.preview_answer_container];

我还在下面添加了一个UITableView（和一个搜索栏）

I also added a UITableView (and a searchbar) below

//setup tableview
UITableView *tempTable = [[UITableView alloc]initWithFrame:CGRectMake(0,44 ,320,self.view.frame.size.height - 44)];
self.tagFriendsTableView = tempTable;
self.tagFriendsTableView.delegate = self;
self.tagFriendsTableView.dataSource = self;
[tempTable release];

[self.view addSubview:self.tagFriendsTableView];

使用此设置，我的滚动区域很小（仅预览部分下方的静态区域）

With this setup, my scrolling area is small (only static area below preview section)

如何修改我的代码，以便
1）我可以向上滚动整个页面，即预览部分和tableview将向上滚动
2）滚动整体将停止时搜索栏到达顶部（导航栏下方）（见截图），但UITableView中的内容仍可滚动

How can I modify my code such that 1) I can scroll the whole page upwards i.e. preview section and tableview will scroll up together 2) Scrolling as a whole will stop when the search bar reaches the top (below navbar) (see screenshot), but the contents in the UITableView is still scrollable

编辑：

添加了UIScroll视图的代码。但是，对我来说没有任何改变。我的代码出了什么问题？

Added code for UIScroll view. However, nothing changed for me. What is wrong with my code?

//setup scroll view
UIScrollView *scroll = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];

//Search
UISearchBar *tempBar = [[UISearchBar alloc]initWithFrame:CGRectMake(0, 120 + 20, 320, 44)];
self.sBar = tempBar;
[tempBar release];
self.sBar.delegate = self;
self.sBar.tintColor = [UIColor colorWithHexString:@"#b6c0c7"];
self.sBar.placeholder = @"Search for FB and DM friends";

[scroll addSubview:sBar];

//setup tableview
UITableView *tempTable = [[UITableView alloc]initWithFrame:CGRectMake(0,144 + 20 + 20 ,320,self.view.frame.size.height - 144 - 20 - 20 - 44)];
self.tagFriendsTableView = tempTable;
self.tagFriendsTableView.delegate = self;
self.tagFriendsTableView.dataSource = self;
[tempTable release];

//Add the scroll view to the parent view
[scroll addSubview:self.tagFriendsTableView];

scroll.contentSize = CGSizeMake(self.view.frame.size.width, self.view.frame.size.height);
[self.view addSubview:scroll];
[scroll release];

推荐答案

我有一个解决方案，

仅使用tableView就够了

use only tableView is enough

1. 将预览视图设为HeaderView你的tableView

1. make the "Preview View" as the HeaderView of your tableView

将搜索栏作为你的tableView的Section Header视图

make the "Search Bar" as the Section Header View of your tableView

你可以完美地完成它：）

you can make it perfectly :)
