I am trying to achieve a scrolling over a fixed image, as you can see on the picture.
I thought I should use a scrollview but I didn't quite get it how to use it and what to include into the scrollview, since the image and the button on the bottom should be fixed. In addition, the content should only be scrollable, when the text is to long.
I think the best solution here would be using a UITableView inside a UIViewController.
You can then set up the cells to make it look exactly the way you want.
For instance the first cell would just be the image, the second cell would be your title, the third one would be your menu bar, and so on.
This may be really useful if you plan to present dynamically the elements inside your UIViewController (for example if you need to use a database, you may want to animate the insertion of the rows only if the content has be downloaded already)
So using a UIViewController, you can just add the UITableView to it and set it up using contraints so that it fills the entire view. Then you can just add your button on the top of your table view, as a subview of your UIViewController's view (not as a subclass of your table view otherwise your button would end up scrolling too).
And again here you would need to add a few constraints to your button to make it look alright!
Just try it like this and let me know if you have any difficulties in the implementation :)
It is very complex to explain, To understand you must know good autolayout
To achieve that you need two scrollview and little math :)
Suppose your headerview height is 200
As you know when using autolayout we need following view hierarchy
Your view Hierarchy should be
--> Main View
--> ScrollView
--> Container View
-->Your HeaderView (200)
-->Content View (Equal height to UIView)
--> UIView (Your tabs like button , followbutton)
--> ScrollView 2
--> ContainerView
-->Subviews
Scroll view 1 Will used wo scroll the headerview and second scrollview will used to scroll other content of scrollview (Like Tab and text content as shown in picture )
Content View (Equal height to UIView) will allow your content view to give height of 200 extra to scroll bottom and your second scrollview will scroll to top which will allow to scroll your other content too

I'm developing an app and I need a view with these elements:
- UITableView
- UITextField and UIButton
- TabBar
As you can guess, I am developing a chat, but when I put the elements in the .xib, I can't show de layer: UITextField and UIButton. If I put them without a view, they dont appear.
If I put a view under the table, and in that view I put the text and the button I get this error: http://pastebin.com/CKfxijz9 (I put the error there because it's to long)
Thanks in advance
There are some ways of dealing with that, depending on how it should behave. Some of them are:
Provide a table footer or header view that holds the button and
the text field.
Nest the table view into another view. The table
view and the view containing the button and text fielt are on the
same level within the view hierarchy. They are rather siblings than
sub- and superview to each other.
Use a UISlider instead of a table. (However, I personally would use the table.)
Here's an approach I've used in the past (not sure if it's best practice, but it works).
Add your button and textfield to a new view (let's call it, bottomView)
Add bottomView to the superview of your tableview
Set the frame of your bottom view so that it fits to the bottom of the screen (this will make it so your tableview will scroll, but keep your bottomView always attached to the bottom of your mainview)
I have a UITableView as a subview in a ScrollView with other widgets around like a button. I'd like to put the button always at the end of the ScrollView and I'd like to have the UITableView to show dynamically more section. How and where shall I determine the Table size, correctly set it and visualize it?
From Interface Builder it seems that I can only set static size to the TableView (which of course limits the number of sections visible) and stick the button position to the bottom whether a rotation happens.
If you have only few simple controls after the table then I'd suggest putting them to the table itself and get rid of the unhealthy (in my opinion) combination of table view inside scroll view.
You might add the button you are talking about to the table's footer.
It may be done in the Interface Builder (drag-n-drop the button to the bottom of the table view) or in the code ([tableView setTableFooterView:myButton];).
If your button should be smaller that table's width then put it inside UIView and locate as you need.
You can also add table header in a similar way...
I want to put a scroll view inside of the table view cell. I have a number of buttons in one cell of table view and I need to scroll that cell to show the appropriate button.
If you want to use a vertical scroll view then I wouldn't suggest you doing it because, as TechZen wrote, there will be a mess in this case.
If you want the inner scroll view to scroll horizontally then it might be achieved by 2 ways:
Implement a custom table view cell that will include a scroll view inside it.
Add a scroll view as a sub-view to your cell that you will return from tableView:cellForRowAtIndexPath: method.
I suggest you to use the second approach.
There are plenty of examples online. Usually the sub-views are labels or image views, but it is not complicated at all to add a scroll view instead...
I don't think you can do this. It would require nesting of scrollviews which isn't really supported.
Even if it was, it would be very difficult for a user to know which scrollview they were hitting with their pudgy finger. Remember, you don't have the one pixel precision of a mouse on the iPhone. You have an area of at least 15x15 pixels. You don't have a scroll bar but instead just drags anywhere on the screen.
Instead, you should use a master-detail pattern. Selecting the cell in the tableview pushes a detail view which has the scroll view with all the buttons.
Why do you want to do it like this?
I think the best idea is to draw your table view manually above your uiscrollview. I did it, and it works. It just takes more effort and drawing accuracy. But that takes a lot of time. :)
The only UITableViews I have worked with thus far are sized to fill the entire page.
I'm trying to create a page in my app where I will have an image and a label on the top of the page followed by a UITableView to hold comments below it.
Something like this springs to mind: http://www.inquisitr.com/wp-content/fbb.jpg
My problem is if I add a UITableView below the image and label, when I scroll the tableview then only the UITableView cells scroll. Not the entire page.
How would I go about making the entire page scroll so that the label and image scroll off the page and more table cells appear?
Thanks.
Put your image and label in a container UIView, and then set that container to the tableHeaderView property of your UITableView.
You could try setting the tableHeaderView property of the UITableView to a custom view containing your controls.
I'm trying to add a UIView, in particular a UIImageVIew, after (that is, below, but not in a z-index sense) a UITableView but before (that is, above) a UITabBar.
You know, the typical "banner/adv space" that you can see everywhere.
My main problem btw is that i don't know exactly where to put it, as a subview of wich view specifically; the UITableView resize automatically according to the space left from the UITabBarController's main view height, minus the height of the tabbar.
I would like it to be put inside the UITableView instead of somewhere else beacuse it is more related to the content of the UITableView, but i have all the autoresizing problems of above. I've tried playing with autoresizingmask, and with the autoresizesubviews flag, but without success. I've even tried the footer ot the UITableView, but that is not fixed in position, it scrolls away if the table is long (expected, and normal).
Is there a way to add a subview in that point, stretching the table itself correctly?
Thanks everybody.
Use a normal UIViewController instead of a UITableViewController. Use the view controller's view as a container view in which you place the table view and the image view. Your view controller can still act as your table view's delegate and/or datasource.
