I'm having trouble creating something similar. I just want a UITableView under a UIView with a UIImageView and a UILabel in it.
If I use a UIViewController and so I can position the UITableView downward, I get this error: "Static table views are only valid when embedded in UITableViewController instances."
If I use a UITableViewController with a grouped style and use contentInset on self.tableView to move it down ([self.tableView setContentInset:UIEdgeInsetsMake(150,0,0,0)];) I can't figure out how to place a view above it. If I try to attach anything to self.view it crashes (obviously). Same happens if I attach anything to self.tableView.
I then tried making the UIView the header of my UITableView section (I only need one section) but I can't get it to move up enough. It just sits inside the UITableView almost.
How do I have a UITableView (grouped style) exist with a UIView above it?
This can be achieved easily using the tableHeaderView property of UITableView. If you are using Interface Builder (which it looks like you are), then you can just drag a UIView above the table view and it will be set as the table's header view. All you need is a UITableViewController; no need for UIViewController and manually laying it out.
That's because the view probably isn't placed on top of the table but rather within the table's section 0 header. Or, even more likely, the view in question is just a regular UITableViewCell with a 0 alpha background.
Either of these options would allow the top view to be scrolled out of frame as the user scrolls under every condition.
I recommend [MDAboutController] (https://github.com/mochidev/MDAboutController)
It's easy to integrate and you don't have to waste any time configuring the UITableView.

I want to customize my tableview. I want to add another tableview in cell. Can we add tableview in cell of another tableview?
Please give me some ideas.
You can embed a UITableView into another UITableView's cell, but due to potential issues with the embedded UIScrollViews it is not recommended.
If you feel like you need a table in a table, first consider if it is not possible to achieve the desired behavior by using sections and cells in the sections (a section in a table might represent the top tableView's cell, and cells in the given section would represent the embedded tableView's cells).
There is no problem with adding a UITableView into a a UITableViewCell, since both of them are UIViews its simply would be translated to adding a subview to a view...
However, keep in mind to consider the following issues:
1- From a user experience perspective, that would be a vertical scroll view inside another vertical scroll view (are you ok with that?).
2- For each cell -in the main container table view-, you would need to handle the table view delegates/datasources. For understanding the logic of how this could be done, you might want to check:
Is it possible to add UITableView within a UITableViewCell.
Putting a UICollectionView in a UITableViewCell in Swift: although it is about adding a UICollectionView inside the cell, it helps to gain the logic of how to achieve such a task.
I have a UITableView in my view controller, and inside the cell there's a horizontal UIScrollView and inside this scroll view, I created many instances of a custom UIView (loaded from NIB file)
UITableViewCell
-- UIScrollView
-- MyView: UIView
Now MyView is not detecting touches, userInteractionEnabled is set to YES on every view in the hierarchy and I tried both ways
Implement touchesEnded: in MyView
Add a UITapGestureRecognizer to it
Both ways don't work, I guess it's something related to the fact that I have a UIScrollView inside the UITableViewCell
I am writing the application in Swift, not Objective-C, I don't think it matters since I guess it's a UIKit issue but who knows.
If you have any hint, I am all ears.
Thank you
Alternative for this case is add UITableViewCustomCell and add UICollectionView with horizontal scroll in Custom cell . It is more optimized way than adding UIView in scroll view because you can greatly speed things up. Instead of instantiating a lot of cells, you just instantiate as many as needed, i.e. as many that are visible (this is handled automatically). If scrolling to an area in the list where there are "cells" that haven't got their visual representation yet, instead of instantiating new ones, you reuse already existing ones.
I love overcast and am getting into iOS development. I see this style of screen a lot.
From what I gather this is a table view with cells and then headers but how is the part at the bottom added in and also the subtitle pieces of text below each row.
I can't seem to find a way in storyboard to do this.
You can drag a UIView object into your UITableView instance in Interface Builder and then configure it the way that you want to.
When you drag a UIView into your UITableView, just drag it to the top, just above the top-most UITableViewCell in your UITableView to create a header. To create a footer, just drag it below the intended UITableViewCell. You can then resize the view and lay it out to your content.
Also, if you would like to do it programmatically, have a look at the UITableViewHeaderFooterView.
You can also create header views and footer views for sections by implementing methods of the UITableViewDelegate protocol such as: tableView:viewForHeaderInSection: and tableView:viewForFooterInSection:.
I have added a subview to my tableview and when ever the user scrolls the tableview, the subview scrolls with it. How do I prevent this? I know it's probably along the lines of not adding the view to the tableview's subviews, but I have no knowledge of any other ways to do this. Thanks.
If you want to make a view a subview of the table view, then you can make it floating (non-scrolling) by changing its origin.y value in the scrollViewDidScroll method.
-(void)scrollViewDidScroll:(UIScrollView *)scrollView {
self.iv.frame = CGRectMake(self.ivOrigin.x, self.ivOrigin.y + self.tableView.bounds.origin.y, self.iv.frame.size.width, self.iv.frame.size.height);
}
In this example, "iv" is a property for an image view, and "ivOrigin" is a property for the initial origin of the image view (defined when I created the image view and its frame in viewDidLoad).
The UITableView is built and intended to be a view of things that scroll.
So, you can either fight that, which as you're discovering is quite hard since everything about the component is built and focused around scrolling and fast display of a subset of the full list data... Or, you can not fight it and put your static item on top of the table as a fixed-position item.
If there's a reason you can't add the table view and your animate-out item in your main view, you can always add a custom UIView class that contains both the table view and your animated view. Have your custom view class expose the contained table view as a .table property, and the container you're putting things in can be tweaked to use "mycontainerObject.tableview" instead of just "tableview" where needed.
Yes, it's a little more work to write the custom UIView subclass and give it a couple properties to hold the UITableView and whatever UIView you're animating out.. but it's likely a lot safer in the long run than trying to "hack" into the UITableView's methods and view hierarchy to try to give it a "fixed in place" behavior.
I would like to add a UISegmentController in the top of my UITableViewController, just like in the AppStore.
I have tried googleing this but either I am search for the wrong things, or too view have written about this.
How can I do this, keeping it in the top with a different design than the UINavigationBar.
For style add segmentCont.segmentedControlStyle=7; which is same as the picture style.
It may not be a UITableViewController. It might be just a UIViewController with a segment control at the top of the XIB and a tableview placed underneath the segment control. That way, you could scroll the table view without scrolling the segment control.
I believe that is a custom header cell for the tableview. You should start by created a custom header with your segmented control inside that.
I think that's a ToolBar with UISegmentedControl or just UISegmentedControl and UITableView under it. You can place them (UISegmentedControl + UITableViewController) on UIScrollView and disable scroll for UITableView. You should make appropriate contentSize for your scrollview.
