how to make a scroll with TextField dynamically, with a button ADD , and if the number of textView it's too big, i can move the scroll and check it.
And no matter how many each text view is placed below that of the top?
Sample:-
I would like to take this opportunity to add my comment as an answer, so that it can reach to maximum users thus helping them.
When you add UITextField(or any other UI element) in UIScrollView, then update the content size of your scroll view programatically.

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 need to create a view controller like this or like user instagram's profile
not exactly same, I just want to add label and buttons and collection view,
but I want all of this in scroll viewController
I think I can't do that from storyboard, so how I can make a view controller scrollable programmatically?
and then I want to add the label and buttons inside the scroll , I can do that programmatically , but how I can add collection programmatically inside it?
One of the possible solutions is to make the whole container a "UICollectionView" -or "UITableView", depends on what exactly you want to build-, and then, create a custom cell for each area depending on what do you want to display in it.
It might sounds a little bit strange in the beginning, but you will notice that it is a great technique to handle scrolling in your scene, including some of extra nice features, such as:
auto scroll content resizing for "UIKeyboardWillShowNotification" and "UIKeyboardWillHideNotification" events.
the ease of showing and hiding sections from the UI (actually they are cells!).
UPDATED: For example:
You can make the first part (red rectangle) as a UICollectionReusableView and customize it by adding your images and button in it, second part (blue square) as a UICollectionViewCell and so on...
This is the general idea of what how you can do it.
I have a UITextView with the Height of 150. I fill up the content dynamically. So, sometime I need to scroll to see the text. But last 3 lines of the content is hidden, it only shows when I scroll the content up. It will hide once I leave the scroll.
Any help to see all the content on the screen with UITextView?
Are you setting the text programmatically after the view is loaded? If so, you may need to resize the content view.
You can also check your nib to make sure the textview isn't hanging off the edge of its parent view ever so slightly.
Finally, you can try resizing the content view to be about 15 pixels higher than it already is.
I would put 2 UITextView inside a UIScrollView. I would then place then accordingly: first the one you want always to be visible and secondly the one you want to stay hidden unless the user scrolls up. To do that, just add then to the UIScrollView and then tweak with the contentSize until you find what you need.
This is probably simple but I do not seem to get it to work. I have a view and inside it I have a scroll view and inside it I have a view with some labels and a button. the height of the text inside the labels changes according to some condition so I need to scroll down to see it. But whenever I try to scroll down it bounce back up without giving me a chance to view the rest of the view.
Basically, I want when I scroll down, the view to remain down as it normally should. Besides I do not see the scroll bar at all when I'm scrolling.
I know I probably do not understand how scroll views work, so I'd appreciate any help to explain to me the behavior of scroll views.
P.S. I built my whole view in a nib file and this specific setup That I mentioned at the beginning is based on a suggestion from one question I read here.
Thanks, Mohsen
you need to set content size of your scroll view
[scrollView setContentSize:CGSizeMake(360,1000)];
you can make the content size dynamic as per your calculation.
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...
