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
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....
I have a custom tab bar controller subclass and instead of a tab bar, I use a custom UIView.
The problem is that I cannot get my view controllers to appear. I see a white screen and the "tab" if I call
[super setViewControllers:]
I get really odd artefacts as far as appearance goes.
So instead I tried setting the selectedViewController directly. I've kind of drawn a blank. Any help would be greatly appreciated.
Can you tell me how you are having a custom view for tabs..
Have u removed tabBar & added ur custom tabView.? and keep in mind if remove your tabBar the whole tabBarController will be removed..
So you need to just hide the tabBar from tabBarController and add ur custom UIView in place of tabBar and everything works fine. You have to select the tab index programatically as per the button selection in your custom view.
You can use view Controller containment concept in order to implement custom tabbar.
[self addChildViewController:content]; // 1
content.view.frame = [self frameForContentController]; // 2
[self.view addSubview:self.currentClientView];
[content didMoveToParentViewController:self]; // 3
You can also use my custom control

I am implementing a WEPopoverController and would like to set the title and put a button on top of the popover. Is it possible to do that with this controller?
This is what I have so far. I am loading TableViewController into the popup.
I tried to set self.title=#"title"; in the tableviewcontroller's viewdidload but that didn't help. I only see the tableview with borders inside.
I tried to create a tableview controller in storyboard and programmatically load into the popup but i couldn't resize it. Plus i am not sure if that would be good programming practice.
This is how i load the popuptableview. Would it be easier to use a UIViewController? I don't really need the tableview.
PopUpTableViewController *popUpTable = [[PopUpTableViewController alloc]initWithStyle:UITableViewStylePlain];
// TestViewController *testView = [[TestViewController alloc]init];
self.popoverSettingsController = [[WEPopoverController alloc]initWithContentViewController:popUpTable];
[self.popoverSettingsController presentPopoverFromRect:frame
inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionDown|UIPopoverArrowDirectionUp
animated:YES];
I looked through the preference options but didn't see anything about title. Would i have to resize the container?
You should create a navigation controller with your popUpTable as root view controller and then use the navigation controller as the content view controller for the pop over.
If the above is done, then your logic of self.title inside popUpTable and creating bar button item will work!
