I'm looking to replicate the basic functionality of the Stores finder in the new Starbucks app (MapView with a tableview bellow it) but am unsure as to how I would go about implementing the sliding aspect of presenting the view
The main aspect of the functionality I am trying to replicate is the ability to present the modal and have it dismissible by sliding it down off the screen as I am able to replicate the Map + Table view already
https://www.cocoacontrols.com/controls/kipulltoreveal Just make a custom cell and you can make it identical.
Well from the Gif you posted, It seems that Starbucks just present the view controller modally which is very easy to do.
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
YourViewController *yourVC= (YourViewController *)
[storyboard instantiateViewControllerWithIdentifier:#"yourView"];
[self presentViewController:yourVC animated:YES completion:nil];
As for dissmissing the view you would need to set ViewController's interactivePopGestureRecognizer delegate to self and then handle its behavior in -gestureRecognizerShouldBegin:
That is, when you want the built-in pop gesture (– popViewControllerAnimated:) to fire, you must return YES from this method. The same goes for your custom gestures - you have to figure out which recognizer you are dealing with.
My thought is this is just a viewcontroller containing 2 basic views:
The background view including tabs and your personal info page which is below tabs.
A table view occupying the whole screen.
section 0: header: empty header / no cells
section 1: header: search bar / 1st cell: mapView trespassing its bounds to cover section header / other cells: locations
Whenever you scroll down 'too much' they defined. They do animation to hide the tableview
To make it looks like a modal view, they make the map corner rounded.

I have presented a tableview controller on a view controller.That tableview comes as full screen on view controller but I do not want to present the tableview on full screen.Is there any way to manage the size of presented vie controller. And the second problem is that i want to present a vie controller which have some label , some text boxes and a table view. Please help
IF you are using iphone device then the viewcontroller will occupy
the full screen .
If the device is iPad,then u can use modalPresentStyle.
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:yourVC];
navController.modalPresentationStyle = UIModalPresentationPageSheet;
[self presentViewController:navController animated:YES completion:nil];
For iPhone ,add the views like UILabel,UITableview to the mainView and present it.
The UITableViewController is used when the table view is the main view of the controller.
In your case it seems more appropriate to use a normal (subclass of) UIViewController and add a UITableView as one of its sub views.
Then you can resize it as you prefer and add other elements (labels...) as additional subviews.
Usually in this configuration you may want to set the view controller as the delegate and dataSource of the table view.
Does this answer also your first question?
You could not change the size of the presented view controller. Another way to do it is by adding it as childViewController by:
[self.view addSubview:tableViewController.view];
[self addChildViewController:tableView];
Then you can change the size of the tableViewController as you wish.
I have Two different UITableView with two Navigation Controller.
I want to display one of them after touching a UIButton in first Table.
In iPhone I use following code
SecondNavigationController second = [SecondNavigationController new];
[self presentModalViewController:second animated:YES];
Note that first is first TableViewController; And second navigation controller it self initiate a UITableView and display it using following code in it's ViewDidLoad method.
SecondTableViewController *root = [SecondTableViewController new];
[self pushViewController:root animated:NO];
Note that first TableView uses application root view controller in iPhone to display it!
And it perfectly works.
In iPad, on the other hand, I use a splitViewController which shows first table view on the left side screen.
I want to show second TableView in the left side too. But above code is not working perfectly. It covers all of iPad screen.
How can I show second UITableView
You need a conditional check which does (pseudo code):
If iPhone
Run current logic
Else
Create a second view controller and push to self.navigationController
I have a view controller that has a map view and a second view under the a tab bar. How do I go about updating the second view when I press buttons on the tab bar?
I tried:
LocationNotesViewController lnvc = new LocationNotesViewController();
lnvc.View.Frame = MainPageTabBarView.Frame;
MainPageTabBarView = lnvc.View;
Nothing happens...the view doesn't update.
I want to update the second view with different things when a user clicks on the tabbar...
If you put a UIView underlying whatever data you want displayed in it, you can use the IBAction of the tabBar to programtically cahnge out the contents of the UIView.
Or you could have the IBActions of the tabbar create new UIViews on the fly, containing whatever you want inside.
Code to do this would be like explained here: http://www.programmerscountry.com/creating-uiviewcontrols-programatically/.
Not exactly the same, but you will understand how it works from that answer.
To switch UIViewControllers use this piece of code:
UIViewController *viewController =
[self.storyboard instantiateViewControllerWithIdentifier:#"4"];
[self presentViewController:a animated:YES completion:nil];
I think this is a work around - but I was able to make this happen by doing:
LocationNotesViewController lnvc = new LocationNotesViewController();
lnvc.View.Frame = new RectangleF(MainPageTabBarView.Frame.X, MainPageTabBarView.Frame.Y - MainPageTabBarView.Frame.Y, MainPageTabBarView.Frame.Width, MainPageTabBarView.Frame.Height);
MainPageTabBarView.AddSubview(lnvc.View);
Since there is no complete, definitive answer to this common recurring question, I'll ask and answer it here.
Often we need to present a UIViewController such that it doesn't cover full screen, as in the picture below.
Apple provides several similar UIViewController, such as UIAlertView, Twitter or Facebook share view controller, etc..
How can we achieve this effect for a custom controller?
NOTE : This solution is broken in iOS 8. I will post new solution ASAP.
I am going to answer here using storyboard but it is also possible without storyboard.
Init: Create two UIViewController in storyboard.
lets say FirstViewController which is normal and SecondViewController which will be the popup.
Modal Segue: Put UIButton in FirstViewController and create a segue on this UIButton to SecondViewController as modal segue.
Make Transparent: Now select UIView (UIView Which is created by default with UIViewController) of SecondViewController and change its background color to clear color.
Make background Dim: Add an UIImageView in SecondViewController which covers whole screen and sets its image to some dimmed semi transparent image. You can get a sample from here : UIAlertView Background Image
Display Design: Now add an UIView and make any kind of design you want to show. Here is a screenshot of my storyboard
Here I have add segue on login button which open SecondViewController as popup to ask username and password
Important: Now that main step. We want that SecondViewController doesn't hide FirstViewController completely. We have set clear color but this is not enough. By default it adds black behind model presentation so we have to add one line of code in viewDidLoad of FirstViewController. You can add it at another place also but it should run before segue.
[self setModalPresentationStyle:UIModalPresentationCurrentContext];
Dismiss: When to dismiss depends on your use case. This is a modal presentation so to dismiss we do what we do for modal presentation:
[self dismissViewControllerAnimated:YES completion:Nil];
Thats all.....
Any kind of suggestion and comment are welcome.
Demo :
You can get demo source project from Here : Popup Demo
NEW : Someone have done very nice job on this concept : MZFormSheetController
New : I found one more code to get this kind of function : KLCPopup
iOS 8 Update : I made this method to work with both iOS 7 and iOS 8
+ (void)setPresentationStyleForSelfController:(UIViewController *)selfController presentingController:(UIViewController *)presentingController
{
if (iOSVersion >= 8.0)
{
presentingController.providesPresentationContextTransitionStyle = YES;
presentingController.definesPresentationContext = YES;
[presentingController setModalPresentationStyle:UIModalPresentationOverCurrentContext];
}
else
{
[selfController setModalPresentationStyle:UIModalPresentationCurrentContext];
[selfController.navigationController setModalPresentationStyle:UIModalPresentationCurrentContext];
}
}
Can use this method inside prepareForSegue deligate like this
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
PopUpViewController *popup = segue.destinationViewController;
[self setPresentationStyleForSelfController:self presentingController:popup]
}
Modal Popups in Interface Builder (Storyboards)
Step 1
On the ViewController you want as your modal popup, make the background color of the root UIView clear.
Tip: Do not use the root UIView as your popup. Add a new UIView that is smaller to be your popup.
Step 2
Create a Segue to the ViewController that has your popup. Select "Present Modally".
Two Methods To Create Popup From Here
Method One - Using the Segue
Select the Segue and change Presentation to "Over Current Context":
Method Two - Using the View Controller
Select the ViewController Scene that is your popup. In Attributes Inspector, under View Controller section, set Presentation to "Over Current Context":
Either method will work. That should do it!
You can do this in Interface Builder.
For the view you wish to present modally set its outermost view background to transparent
Control + click and drag from the host view controller to the modal view controller
Select present modally
Click on the newly created segue and in the Attribute Inspector (on the right) set "Presentation" to "Over Current Context"
Feel free to use my form sheet controller MZFormSheetControllerfor iPhone, in example project there are many examples on how to present modal view controller which will not cover full window and has many presentation/transition styles.
You can also try newest version of MZFormSheetController which is called MZFormSheetPresentationController and have a lot of more features.
You can use EzPopup (https://github.com/huynguyencong/EzPopup), it is a Swift pod and very easy to use:
// init YourViewController
let contentVC = ...
// Init popup view controller with content is your content view controller
let popupVC = PopupViewController(contentController: contentVC, popupWidth: 100, popupHeight: 200)
// show it by call present(_ , animated:) method from a current UIViewController
present(popupVC, animated: true)
Imao put UIImageView on background is not the best idea . In my case i added on controller view other 2 views . First view has [UIColor clearColor] on background, second - color which u want to be transparent (grey in my case).Note that order is important.Then for second view set alpha 0.5(alpha >=0 <=1).Added this to lines in prepareForSegue
infoVC.providesPresentationContextTransitionStyle = YES;
infoVC.definesPresentationContext = YES;
And thats all.
Swift 4:
To add an overlay, or the popup view
You can also use the Container View with which you get a free View Controller ( you get the Container View from the usual object palette/library)
Steps:
Have a View (ViewForContainer in the pic) that holds this Container View, to dim it when the contents of Container View are displayed. Connect the outlet inside the first View Controller
Hide this View when 1st VC loads
Unhide when Button is clicked
To dim this View when the Container View content is displayed, set the Views Background to Black and opacity to 30%
You will get this effect when you click on the Button
You can do this to add any other subview to the view controller.
First set the status bar to None for the ViewController which you want to add as subview so that you can resize to whatever you want. Then create a button in Present View controller and a method for button click. In the method:
- (IBAction)btnLogin:(id)sender {
SubView *sub = [[SubView alloc] initWithNibName:#"SubView" bundle:nil];
sub.view.frame = CGRectMake(20, 100, sub.view.frame.size.width, sub.view.frame.size.height);
[self.view addSubview:sub.view];
}
Hope this helps, feel free to ask if any queries...
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....
