Could recommend me any third part library to animate custom transition to new view controller directly from UITableView, where cells slides out (up and down) and smoothly transmit with opacity to new controller.
I suppose you code put in some gesture recognizers and set them as IBActions to segue to a different view controller.
In general you could just set an animation when a button as a clicked, to play the animation and then open a new view controller.

I have an MKMapView with a container view which holds a view controller that I'm using as an interactive legend. I can't seem to figure out how to have the view controller (a UITableViewController in actuality) behave normally to touches but not pass them to the map view. Right now it acts like it should except if you double tap in the legend, the map view zooms in. How can I have the table view controller intercept that and any other gestures and not pass them through to the map view?
Here's what I'm doing to stop the map view moving around in a table cell:
mapCell.mapView.zoomEnabled = NO;
mapCell.mapView.scrollEnabled = NO;
Where mapCell is the cell in question and mapView is the MKMapView object showing the map.
I have initialized a UIViewController with a nib file which displays fine when I push it on my viewstack.
However when I try and present it as a modal viewcontroller, the view of that controller is clipped at the bottom during the transition animation only. After the transition is done, the view displays just fine.
Anyone have a clue what is going on here? Do I need to set additional properties on my viewcontroller that is presenting my modal viewcontroller?
I have tried re-setting the frame of my viewcontroller without success...
I drag out a toolbaritem in storyboard and set it on my nav controller, but when I run my code it's not there, is there something I'm missing?
EDIT:
Tried setting it in code as well in my viewDidLoad method:
UIBarButtonItem *rightBarButton = [[UIBarButtonItem alloc] initWithTitle:#"Map" style:UIBarButtonItemStyleBordered target:self action:#selector(viewMap)];
self.navigationItem.rightBarButtonItem = rightBarButton;
Won't work either.
Here's how it's set up in my storyboard:
UPDATE:
Just found my problem. In my controller code when I update it's contents I change the right bar button item for a spinner and never set it back to what it had before.
UINavigationController already has a toolbar built in. It has a property toolBarHidden which is set to YES by default, which is why it is not normally seen. If you are using storyboard you can easily make the built-in bottom toolbar visible by checking the checkbox "Shows Toolbar" in the inspector when the Navigation Controller is selected.
See the UINavigationController documentation here for more details.
EDIT:
Ok, it sounds like what you are trying to do is add a right button to your view controller's UINavigationItem. To do this in storyboard, drag a "Bar Button Item" from the Objects Library onto the Navigation Item in your ViewController. You can then set the title/style/etc of the bar button item. If nothing still shows up when you run your app, make sure that your ViewController is connected properly with a segue to the navigation controller.
Also make sure you are adding the Bar Button Item to your view controller's Navigation Item, NOT to the View Controller itself. Here is how the setup should look in your storyboard:
To add an item to a navigation bar, you need to add a Bar Button Item to the Navigation Item contained in the view controller. Go to your storyboard, find the right VC, and find the navigation item (it's in the hierarchy shown in the navigation controller 'scene'). Just drag a Bar Button Item into that hierarchy underneath the nav item, or directly onto the navbar in the visual builder display.
The navigation controller only looks at your VC's nav item when that VC is pushed onto the stack; hence modifying the VC's nav item in viewDidLoad has no effect.
(I've done this programmatically before but I don't have the code with me, so maybe I'll add that later...)
The Apple Pages and Numbers apps have popovers (for "tools" etc) that close with a lovely fade out effect when you rotate the device. I'm trying to recreate this, but my popovers always seem to close instantly, so the animation of the rotation doesn't look quite as smooth. I'm currently using:
- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation duration:(NSTimeInterval)duration
{
[toolsPopoverController dismissPopoverAnimated:YES];
}
Does anyone know the best way to achieve the same effect seen in Pages/Numbers?
Thanks!
Based on the documentation for the UIPopoverController (emphasis added):
If the user rotates the device while a popover is visible, the popover controller hides the popover and then shows it again at the end of the rotation. The popover controller attempts to position the popover appropriately for you but you may have to present it again or hide it altogether in some cases. For example, when displayed from a bar button item, the popover controller automatically adjusts the position (and potentially the size) of the popover to account for changes to the position of the bar button item. However, if you remove the bar button item during the rotation, or if you presented the popover from a target rectangle in a view, the popover controller does not attempt to reposition the popover. In those cases, you must manually hide the popover or present it again from an appropriate new position. You can do this in the didRotateFromInterfaceOrientation: method of the view controller that you used to present the popover.
It would appear that by calling [toolsPopoverController dismissPopoverAnimated:YES] in the willAnimateRotationToInterfaceOrientation: method, you are dismissing with an animation while the popover is hidden during the rotation transition.
If you call the dismissPopoverAnimated:YES method in the didRotateFromInterfaceOrientation: method instead, the default behavior with the popover in the new position should present before the dismiss animation is invoked.
If the default animation is still not what you are looking for at this point, I would create a custom animation block and manage the fadeout or re-sizing explicitly to meet your desired needs.
This worked for me by calling dismissPopoverAnimated: from willRotateToInterfaceOrientation:duration:.
I added a subview to my application. The view controller is a UITableViewController. When I open the .xib file I see the table, but I can't drag a navigation bar onto it. So once the user enters the view, they have no way of getting back to the previous screen. What can be done?
the UITableView nib representation cannot have it. You can simulate the UI in the case you have a navigationController.
If you want to have a navigation controller, your UITableView has to be pushed into the stack of navigationController.
Assuming your view controller is ViewControllerA has a navigationController, then this method will make sure you have navigation controller in your UITableView:
[viewControllerA.navigationController pushViewController:tableViewController animated:YES];
