I have TableViewController with a custom cells.
For table is responsible class:
#interface CustomTableViewController : UITableViewController
For cells is responsible class:
#interface CustomTableViewCell : UITableViewCell
The ImageView are located in cell of table.
How I can open new controller when I click(touch) at ImageView inside cells?
As it appears I must to use UIViewController near UITableViewCell that to open new viewController, is not?
Usually this kind of stuff is handled inside UITableViewDelegate method didSelectRowAtIndexPath. However the table view calls this method when the entire cell is tapped.
If you want to trigger the action only for the image, you might have to add UITapGesture to the image view. Do not forget that image views have userInteractionEnabled set to false by default. There are two ways to communicate the tap event to the view controller that i can think of right now. Either by delegation or closure. The latter one requires less code.

The full error is: The playerView outlet from the TableViewController to the AVPlayerView is invalid. Outlets cannot be connected to repeating content.
Similar answers like this one have not worked (assuming I am attempting them correctly, I'm very new to iOS).
All I want is a view within a TableViewCell.
I've tried dragging a View in Storyboard to the contentView (and cell) of my TableViewCell, assigning it a class of AVPlayerView: UIView (and a subclass of tableViewCell: AVPlayerView: UITableViewCell), then ctrl+dragging from that view in the storyboard into my TableViewController. Then it doesn't compile. Really confused, thanks for the help.
Your table view can have static content or dynamic content.
If you want the table view to have always the same content, set it to static (in interface builder), and then you can link the outlets like that, in the UIViewController.
If you want the table view cells to change dynamically, you cannot do it that way. Because you could repeat cells and the outlet would be ambiguous. You need to create a UITableViewCell subclass for your cells, and create the outlets there.
To clarify: in dynamic table mode, you need to ctrl+drag the outlet into the UITableViewCell subclass, not the view controller.
Very simple solution is:
Just take the view or NSLayoutConstraint reference outlets in the subclass of table view cell instead of table view controller and access using object of table view cell in cellForRowAtIndexPath method or any other method.
I would like to programmatically apply some view modifications once a UICollectionViewCell has been created and all its view outlet are being assigned (right as a UIViewController's viewDidLoad method). However I don't want the code to be re-run when the cell is being reused as this view initialization/modifications have to be done only once. Is there a method that I should override in my custom UICollectionViewCell implementation that is being called as soon as the view outlets are assigned?
There is the applyLayoutAttributes: methods that is just called after the view is added to the collection view. However from its name and its description it doesn't sound to be the right place to initialize the view. In addition this method might be called for every re-use as well. However using an initialized-flag this could be worked around.
If it's being loaded from a storyboard or nib then you can do that in.
- (void)awakeFromNib
If it's in code then there is an init method something like initWithFrame:reuseIdentifier.
Somrthing like that anyway.
These are both run once when the cell is first loaded.
I've tried adding a UIButton to the cell's contentView, which wasn't getting called. Then I tried adding a touchesBegan method to the cell. It's not being called. The cell has it's background color being set, and I can see in the extrapolated view that XCode now provides that it's the topmost view.
Any thoughts as to why interaction might not be working?
I think answer lies into UICollectionView delegate methods and datasource, you don't need touchedBegun etc,
I guess you want to know which cell has been tapped. More codes will definitely helps.
In storyboard do this,
A viewController with UICollectionViewCell inside it.
Add UIViewController subclass in your project and make your storyboards viewController as its subclass.
Add UICollectionView subclass and make your UICollectionViewCell its subclass.

I have a reusable UIViewController subclass (an audio/video player, let's call it MediaController). It works ok when I add it to some other view controller as a child view controller, however my requirement is to also add it in a UITableViewCell subclass. Since -addChildViewController: is a method of UIViewController, I'm adding my view to the cell like that:
self.mediaController.view.frame = self.containerView.bounds;
[self.containerView addSubview:self.mediaController.view];
(containerView is just a placeholder view in the cell's view hierarchy).
However, this causes problems, first because MediaController is having some logic in -viewWillAppear and -viewWillDisappear (that of course never get called) and second because it seems that autolayout does not work properly when MediaController's view is added to the cell.
Do you think I have some other option (maybe use the UITableViewController that owns the cell as a container?) or I will not be able to use this MediaController at all?
This question is the most relevant when I search, but it still doesn't solve my problem.
Thanks!
One thing I might try if it's possible is to have a UITableViewController that has static cells.
If you're using a UIStoryboard drag and drop a UITableViewController and change the content to Static Cells then in the cell you want to have your MediaController drop a Container View into that cell. Then drag and drop from that Container View to your MediaController and setup an embed segue.
The appropriate viewLifecycle methods should be called when displaying.
Here is the UIStoryboard setup
The other answer from aahrens did not work for me since I have a complicated table view and I was not using storyboards from the beginning.
What I ended up doing was to pass a weak reference of the UIViewController to the cell, so that I can make the "normal" call to -addChildViewController:. Ugly, but works fine.
I want to add a simple static TableView to my UIView. So i dragged it into my UIView. Added the TableViewDataSource and Delegate Protocols to my ViewController class. Created an outlet to my tableview and connected the datasource and delegate outlets to the viewcontroller.
But i still get an error message which says that Static table views are only valid when embedded in UITableViewCOntroller Instances ? Any Ideas how to solve this Problem ?
PS: I am using UIStoryboards for designing the UI
Use a containerView (drag one onto your UIView) which will link to a UITableViewController instead. You will use the prepareForSegue method to initialize the table view controller.
Oh, and you might want to accept answers that help you or no one will help you anymore.
If you want static cells, in your Storyboard, click on the tableview, then in the inspector, change the Content from 'Dynamic Prototypes' to Static Cells. You can also segue these cells to a new controller without having to set up data sources and delegates for the table.
