Table views are a fundamental component of almost any iOS app. For example, many developers make their life harder using a scroll view when a UITableView would be a better choice. Finally, architecture is crucial for table views. The code of the table view data source often ends inside view controllers when it should go into a separate class. Until then, you need to know the right approach to using table views with data sources and delegates.
As a developer you need to know which one works better to solve your problem. That could take a couple of years. Until then, you need to learn how to use table views if you want to become an iOS developer.
The UIKit framework offers many classes, all with a specific purpose. These guidelines are helpful to pick the right tool. Their content is unstructuredwhich means there are no repeating elements or patterns. Table views manage vertical lists of repeating elements. The word vertical is essential here because a UITableView arranges its components into a single column.
There is no such thing as a horizontal table view. To arrange items horizontally, even if scrolling will only be vertical, you need a collection view :.
To be precise, table views and collection views are also scroll views. It might look like table views are made only to manage repeating elements. In reality, though they are the right choice for almost any screen that needs to scroll vertically. Have a look, instead, at this small collection of table view designs I put together on Dribble :. So, my recommendation is: if you need scrolling, use a table view or, eventually, a collection view.
You need scroll views only in a few, specific cases.
UITableView scroll to top with Swift
For example, to display content with a vast area that you can zoom or scroll in any direction, e. The app will have two screens to explore both plain table views and table views with sections.
You can get the complete project on GitHub. For starters, we need to set up the navigation flow of the app in the Xcode storyboard. The two navigation controllers provide a navigation bar to each tab.Table views on iOS display a single column of vertically scrolling content, divided into rows. For example, the Contacts app displays the name of each contact in a separate row, and the main page of the Settings app displays the available groups of settings.
You can configure a table to display a single long list of rows, or you can group related rows into sections to make navigating the content easier. Tables are commonly used by apps whose data is highly structured or organized hierarchically. Apps that contain hierarchical data often use tables in conjunction with a navigation view controller, which facilitates navigation between different levels of the hierarchy.
For example, the Settings app uses tables and a navigation controller to organize the system settings. The standard cell configurations display a simple combination of text and images, but you can define custom cells that display any content you want.
You can also supply header and footer views to provide additional information for groups of cells. Xcode creates a new scene that includes both the view controller and a table view, ready for you to configure and use. Table views are data driven, normally getting their data from a data source object that you provide. If the content of your table never changes, you can configure that content in your storyboard file instead.
Table views support UIKit app restoration. When its parent view controller is saved, the table view automatically saves the index paths for the currently selected and visible rows. The object that acts as the prefetching data source for the table view, receiving notifications of upcoming cell data requirements. A protocol that provides advance warning of the data requirements for a table view, allowing you to start potentially long-running data operations early.
Returns a reusable table-view cell object for the specified reuse identifier and adds it to the table. Registers a nib object containing a header or footer with the table view under a specified identifier.How to create uitableview with multiple sections in iOS Swift

Topics Creating a Table View. Style Initializes and returns a table view object having the given frame and style.Posted by: admin November 22, Leave a comment. I want to to customize UITableView header for each section. What i do want to do is get current header for each section and just add UILabel as a subview.
First question, is there any way to get default section header? The code to configure the header is similar to how you configure for row cells.Honda accord catalytic converter bolts
Swift version of Lochana Tejas answer:. For example. In the implementation of this method create a UIView, add a UILabel to it with the properties you want to set, and of course set its title to the given one. I was confused because I did something like this for the first time.
So to clear my confusion open the xml format of the MainStoryBoard and found the Image View was added as a header. This is the easiest solution possible. The following code can be used directly for creating a custom section header. If you just want to add title to the tableView header dont add a view. In swift 3. For example, I wanted to add a graph button on right edge of section header:. If you want to change the font of the textLabel in your section header you want to do it in willDisplayHeaderView.
Good luck! Use tableView: willDisplayHeaderView: to customize the view when it is about to be displayed. This gives you the advantage of being able to take the view that was already created for the header view and extend it, instead of having to recreate the whole header view yourself.
Here is an example that colors the header section based on a BOOL and adds a detail text element to the header. Tags: uitableviewview. January 9, Swift Leave a comment.

CGColor view. I needed one and only one header in the whole UITableView. It worked for me. Thanks xCode and swift.In this tutorial you will learn how to add a header and a footer view to a UITableView. There are two ways that we can add the header and footer, one way is to add it in using Interface Builder and the other way is to do it with code.
In this tutorial we will be using both Interface Builder as well as code. I will assume that you have a UITableView in your Storyboard and that you have already created an outlet for it. To do this, update your view controller class to look like this:. Now that we have adopted those two protocols, we need to set the tableviews delegate and datasource to self. I will be doing this in the viewDidLoad method.
Add the following two lines to your viewDidLoad method:. There are two more things that we need to do and then our tableview will be set up. Adding a header to the tableview in Interface Builder is easy, once you have your tableview drag a new view over the tableview towards the top, a blue line should appear, when it does you can place the view.Best liveries gta 5
See the below gif:. The next thing we are going to do is change the background color of the view to blue so that it is easier to see. The footer is basically the same as the header but there can be a catch if you only want a footer view. To only have a footer view, you will need to add a prototype cell, that will allow you to add a footer view below the cell.
Let's add a footer now, again, we just need to drag a new view onto the table view, but this time place it below the other view. When you place it below the other view you should see a blue line again, when you do, it will be in the correct position. See gif below:. I am going to change the color of the footer view to red. Once that is done, build and run the app, it should look like this:.
Using Interface Builder is that simple. In the next steps we will add the header and footer with code.Jan 2016
There are two ways that we can do it with code, and we will go through both of those ways. I am going to remove the header and the footer in Interface builder, so that we can add them back in with code.
As I mentioned before there are two ways to add a header and footer view, but there are also two ways using just code. The second way is more powerful and it allows you to easily create a header for sections of a tableview.
The view code itself is the same as when we used the tableview property.
This is basically exactly the same as adding a header. Instead of using the tableHeaderView property we will use tableFooterView property, and the delegate methods will change from the header methods that we used, to the footer methods. Adding header and footer views to a tableview is quite simple. Once you know how to do it, it is very easy to do in the future.Abbreviazione corso di studi

Scrolling the tableview up leaves the section header at the bottom of the frame of the header and doesn't scroll along with the tableview. Is this fixable? Good find. This seems to be due to the tableView 's contentInset not being changed while scrolling down.
I've revisited this bug and sat down for a good couple of hours but I can't seem to find a good solution. It's a known bug without a clear workaround. Every "fix" creates another bug. I've found a couple of blog posts and stack overflow posts that tries to fix this in other projects.
One is This blog post where a subclass of a uitableview repositions each table header view. May work for APParallaxHeader, but i don't think it's something that could be automatically integrated into the project.
Someone please correct me if I'm wrong. The other fix is fixing the contentInset. I've already tried this for APParallaxHeader, and it breaks the scroll inertia and makes the parallax feel sluggish and buggy. It just annoys everyone who's watching the thread. Mind sharing these as well? Amnell is there any update on this bug. Have you tried setting the tableView type as grouped?
I haven't tried it myself though. Ronaldoh1 I believe that should fix the issue. Can you please try that? RishabhTayal Grouped wont give you a sticky header thou, and thats the main issue with this bug.

A constant that indicates how the reloading is to be animated, for example, fade out or slide out from the bottom. See UITable View. Row Animation for descriptions of these constants. The animation constant affects the direction in which both the old and the new rows slide.
For example, if the animation constant is UITable View. Row Animation. Reloading a row causes the table view to ask its data source for a new cell for that row.
How to add a section header to a table view
The table animates that new cell in as it animates the old row out. Call this method if you want to alert the user that the value of a cell is changing. If, however, notifying the user is not important—that is, you just want to change the value that a cell is displaying—you can get the cell for a particular row and set its new value. When this method is called in an animation block defined by the begin Updates and end Updates methods, it behaves similarly to delete Rows at: with:.
The indexes that UITable View passes to the method are specified in the state of the table view prior to any updates. This happens regardless of ordering of the insertion, deletion, and reloading method calls within the animation block.
A Boolean value indicating whether the table view's appearance contains changes that are not reflected in its data source. Inserts rows in the table view at the locations identified by an array of index paths, with an option to animate the insertion. Language: Swift Objective-C. Instance Method reload Rows at: with:. Reloads the specified rows using a given animation effect. SDKs iOS 3. Framework UIKit. See Also Reloading the Table View. Row Animation Reloads the specified sections using a given animation effect.
Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. That's not how the header works in a table view. You can create a header for the whole table as opposed to a per-section title using the tableHeaderView property; but if you want to have a widget that is always displayed on screen you're better off creating another view controller to which you add the table as a child view.
Just drag a label on TableView before the cell ,note that you have to drag label on TableView not in cell and give you title. How are we doing? Please help us improve Stack Overflow. Take our short survey. Learn more. Add Header to tableview in swift Ask Question.
