I'm trying to add this custom control below my tableview in a TableViewController:
https://github.com/zogieosagie/RMEIdeasPullToSortControl
In the example the creator gives, the control is implemented using a ViewController and an added tableview, but I want to use it in a TableViewController. I have created and initialized it as shown in the example but I cannot get it to show up behind the table. Any ideas?
Here is a screenshot of the control above my tableview: https://www.dropbox.com/s/ojfpacxelcy9cqm/Photo%20May%2028%2C%208%2057%2035%20PM.png
Here is my code in the viewDidLoad method:
[self.tableView setBackgroundColor:[UIColor clearColor]];
self.rmeideasPullDownControl = [[RMEIdeasPullDownControl alloc] initWithDataSource:self delegate:self clientScrollView:self.tableView];
self.sortTitlesArray = [[NSArray alloc] initWithObjects:#"Listed from A - Z", #"Listed from Z - A", #"Brand value: HIGHEST - LOWEST", #"Brand value: LOWEST - HIGHEST", #"Founded: OLDEST - NEWEST", #"Founded: NEWEST - OLDEST", nil];
CGRect originalFrame = self.rmeideasPullDownControl.frame;
self.rmeideasPullDownControl.frame = CGRectMake(0.0, 45.0, originalFrame.size.width, originalFrame.size.height);
//It is recommended that the control is placed behind the client scrollView. Remember to make its background transparent.
//[self.view insertSubview:self.rmeideasPullDownControl belowSubview:self.tableView];
[self.tableView addSubview:self.rmeideasPullDownControl];
[self.tableView sendSubviewToBack:self.rmeideasPullDownControl];
Table view controllers do not lend themselves to managing anything other than a table view. In a table view controller the content view of the view controller is the table view.
You should not try to add other views as subviews of a table view.
Those 2 things combined mean that you can't do what you are trying to do.
Instead, you should create a regular UIViewController. In your storyboard, add a container view to the view controller's content view. Create a UITableViewController as a separate scene, and then control-drag from the container view onto the table view controller. That will set up an embed segue, so your table view controller becomes a child view of the regular view controller. Now you can do whatever you want to the main view controller's content view, including adding other views behind the table view.
Do you mean that you are using a Table View Controller on the storyboard? Or do you mean that your backing code is a subclass of UITableViewController?
I haven't used this project before but I'm guessing you are using a Table View Controller on the storyboard, in which case there is no backing view for the RMEIdeasPulldownControl to attach to (the top-level view is a UITableViewController). If you look in the example it needs to be attached to a scrollview (like a table view) but it needs to be inserted into a view (like a UIView)
If you meant the second one then I'm not sure, UITableViewControllers are subclassed from UIViewControllers and are really very similar, so I can't imagine any trouble arising from that.
It isn't possible directly, but you can create UIViewControllerClass with relevant storyboard UIViewController
add a MyUIView in hierarchy then UITableView next to MyUIView
attach datasource and delegates for UITableView and use MyUIView as per your requirement.

in carousel viewForItemAtIndex i am using reuse view something like this-
-(UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view{
if (!view){
UIViewController * viewController = [self.storyboard instantiateViewControllerWithIdentifier:#"PopUpView"];
view = [viewController.view viewWithTag:1];
CGRect Frame = CGRectMake(view.frame.origin.x+300, view.frame.origin.y, view.frame.size.width+300, view.frame.size.height-350);
view.frame = Frame;
}
Is it a good approach?
I would say that this is not a good approach. You are creating a view controller here only to immediately throw it away, which is pointless.
If you just need the view, you can load it directly from a nib file without needing a view controller. You can bind it's actions to the main view controller for the carousel (there is an example of this in ControlsExample project included with the library), or create a custom view class and bind the subview outlets to the view itself.
If you want to use a view controller for each carousel item view (which I don't recommend, as this is not the convention used for UITableView or UICollectionView, which iCarousel is modelled on) then you should add the view controller as a child view controller of the main carousel controller, but this is fiddly as there is no obvious place where you can remove the child controller again when its view goes offscreen).
As per approach, there is nothing wrong in using a view controller's view. UIView is where you handle what it looks like, UIViewController is the class where you handle events. If you want to handle any events then using UIViewController's View is a better option.
I'm trying to add a tableview as subview to my tableViewController, but I want to setup the cells in storyboard. It will be a static tableview.
This is the code for calling the tableview on button click.
- (IBAction)botaoAdicionar:(id)sender {
AtividadesPraticadasTableView *tableview = [[AtividadesPraticadasTableView alloc] initWithFrame:CGRectMake(0, 170, 320, 320) style:UITableViewStylePlain];
[self.view addSubview:tableview];
}
In the tableview class I have this:
#implementation AtividadesPraticadasTableView
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
// Initialization code
}
return self;
}
Now, I have a viewcontrollerin storyboard with a tableview, which the class of the tableviewI changed to this file AtividadesPraticadasTableView. It has three static custom cells in storyboard, therefore it opens a blank default tableview.
What am I missing?
Static table views are entirely contained within the storyboard, and require information from the storyboard to display their content.
You've defined a static table view controller in the storyboard, populated it and set the tableView's custom class to your custom class, but when you want to add the table view you are just instantiating a table view of that class. That isn't going to get any of the information you've added to the storyboard.
In addition, the static cells information is read and understood by the UITableViewController, not the UITableView, so you are at the wrong level there too.
You need to do the following:
Get a reference to the storyboard, either from your original view controller's storyboard property (if it is on the same storyboard as your static table) or using storyboardWithName:bundle:.
instantiate the table view controller from that storyboard, using instantiateViewControllerWithIdentifier:. This will create a table view controller object containing all your static cells
Add this as a child view controller to your original view controller, using addChildViewController:
Add the table view controller's tableView as a subview
It may be simpler to add a container view in the storyboard to hold this view, and reveal it when the button is pressed, as Mike Slutsky suggested - this will do all of the instantiating and adding and child view controller-ing work for you, but the principle is still the same.
Also, adding a table view as a subview to a table view controller sounds very dodgy - a table view controller already has a table view as its view, and you can't really add subviews to that.
The thing your missing is the association between the programatically instantiated tableview and the UITableView that you put in your storyboard. You cannot just draw UITableViews in your storyboard and start instantiating new UITableViews in the controller's code and expect xcode to know which UITableView you wanted to use from the storyboard. Use an IBOutlet to connect a global variable for the controller to the UITableView in the storyboard, then the controller will know what you're trying to refer to. If you want that UITableView to appear on a button click, simply set the UITableView to hidden by default in the storyboard and then unhide it when the button is pressed.
The thing You are missing called manual. Check this protocol for TableView dataSource https://developer.apple.com/library/ios/documentation/uikit/reference/UITableViewDataSource_Protocol/Reference/Reference.html#//apple_ref/occ/intf/UITableViewDataSource

I have a container view controller that consists of a navigation view at top, and a content view for the remainder of the screen. The navigation menu consists of several buttons, some of which present a popover with UITableView for secondary navigation. This all worked until I assigned a child view controller and set it's view as subview of the content view. Now, the popover appears, but has nothing inside it (no tableview, just black).
Why is this?
Here's the code I added for the child vc in container view:
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
ContentWebViewController *initialVC = [[ContentWebViewController alloc] init];
[self addChildViewController:initialVC];
initialVC.view.frame = self.view.bounds;
[self.containerView addSubview:initialVC.view];
self.currentController = initial;
}
See the screenshot below. I added a vc with a simple webview showing google (just as a placeholder for now). The popover was working fine before I assigned the child VC.
Maybe it will help other in other cases -
If you are using size classes (probably you are since you are developing this to iPad) -
Design your popover view controller in Any-Any size and it should be OK - after that you can return to your wanted size.
(You can also uninstall the size classes of any object in that view controller instead of redesign the VC)
I somehow (don't ask me how) changed the class that my table view controller was inheriting from. It should have been (obviously) UITableViewController, but was UITableViewController, so initWithStyle was not being called....
I have implemented a PDF viewer. Currently it is a UIViewController that contains a UIPageViewController.
My toolbar, some overlay elements (like quick access to certain pages of the PDF) are added to the standard UIViewController's view.
However I wonder if that is required? Would it be somehow possible to inherit from UIPageViewController and have the paging effect for sub controllers and still have "floating" elements on top that won't be paged?
or is the containment the way to go?
We should create UIPageViewController programmatically and add its view to another UIViewController's view as a subview. And the elements that we want them to be 'overlay' should be subviews of the host UIViewController.
For example, in - viewDidLoad:
UIPageViewController *pvc = // init this on your own way
pvc.dataSource = // your data source
// Set page view controller's view's frame to match host view's frame
pvc.view.frame = self.view.bounds;
// And here comes the magic
[self.view insertSubView:pvc.view belowSubview:<any subview>];
Briefly we only use UIPageViewController's view but not itself.
Hope this helps.
I have a UINavigationController and UITableView in my MainWindow.xib. I'm trying to insert a non-touchable/non-movable image at the top of the view. (I don't want to simply change the UINavigationBar background, as from what I've experienced, the UINavigationBar height cannot be arbitrarily increased.)
As this is a root view, its behaviour is controlled by my RootViewController. When the view loads, I hide the navigation bar using self.navigationController.navigationBarHidden = YES;
I've tried adding a UIView to the top of the UITableView, but when the user scrolls through the table, the top image moves. How can I place a stationary image at the top of the UITableView without it moving as if it were a cell and without using a UINavigationBar background image?
Naively-Considered Possibilities:
Enclose the view in another view, the top of which contains the image?
Overlay an image mask at the top of the screen?
(HIG violation, anyone?)
If your view controller is a UITableViewController you can't easily add another view because the tableViewController just manages a single view which is the UITableView. I recommend using a plain UIViewController instead where you add a UIView for your top view and a UITableView for your content as subviews to the main viewController.view. Then, implement the UITableViewDelegate and UITableViewDataSource protocols in your UIViewController.
You can create another UIViewController which contains the UITableViewController and your static image on top. This way, you can even resize the table view so the static image is displayed above and not over your table.
UIViewController *middleViewController = [[UIViewController alloc] init];
[[middleViewController view] addSubview:tableView];
[[middleViewController view] addSubview:staticImageView];
...
[navigationController initWithRootViewController:middleViewController];
Has been a long time since I made my last cocoa application, so I cannot promise that it works.
