Welcome to a new SwiftUI tutorial! In this article, we will learn how to create a side menu with a smooth slide-out animation, also called hamburger menu, in SwiftUI. These kinds of menus are often used in Android apps, but can also be useful in iOS apps as an alternative or addition to tab bars.
The first thing we do is to create the main view of our app.Laptop screen black and white lines
This view should only contain a button which we will use to toggle the side menu later. Therefore, add a Button with the corresponding Text to the ContentView.
Name the outsourced view MainView. The MainView should fill the whole screen. In order to know the height and width of the overall super view, we wrap the MainView into a GeometryReader.
We can now use the geometry property to adjust the frame of our MainView to fill the entire screen. Now we will design our side menu. Our menu should contain four vertically arranged menu items. For this purpose, we use a VStack with. Each menu item consists of an icon and a corresponding text. Thus, we add an HStack to our VStack for our first menu item. The first menu item should have a fairly large distance to the top.
To do this we use the. To increase the distance between the menu items and the edges, we apply some overall padding to the entire VStack. We also want our menu to be as wide as possible and the individual items to be aligned to the left. We finally give our menu a dark grey background and make sure that it also goes beyond the so-called Safe Area, meaning that it also fills out the upper and lower edges. The corresponding preview should now look like this:. To keep track of whether the MenuView should be displayed inside our ContentView or not, we declare an according State:.
When this State is true, the MenuView should be shown on top of our MainViewaligned on the left side. The menu should only cover the half of our screen, therefore we add the following.
Additionally, we want to shift our MainView to the right when the side menu is opened. We also want to disable any functionality of our MainView until the menu is closed again. Run the app preview in live mode to try it out! At the same time, our MainView shifts to the right and the button it contains is grayed out. So far, however, our menu gets still displayed without any kind of animation.
Therefore, we wrap the action of the button in our MainView into a withAnimation statement. Now we can attach a transition modifier to our MenuView and specify that the menu should move in from the left side. Hint : If the animation is not being executed in the live preview, run the app in the regular simulator. We want to be able to close the menu again by swiping from right to left. For this purpose, we use a so-called Drag Gesture. When we have swiped far enough we want to close our menu by setting the showMenu State to false again.
In this, we check whether the user has exceeded a certain threshold value with his swiping gesture.But this approach had a few weaknesses:. Nowadays, I usually recommend using a Tab Bar Controller instead of a slide-out menu.
It takes a while to get used to Custom View Controller Transitions. Download the starter project zip file. You can tap the buttons in the corners to open and close the modal.2007 ford e350 fuse diagram
This tutorial only uses. Right for opening the menu, and. Left for closing it.Yahweh song
This method calculates the progress in a particular direction. For example, if you specify the. Left tracks progress in the negative-x direction. Currently, the menu modal opens using the default slide-up animation. We want to override this with a custom animation where the main content slides-right to reveal the menu underneath. Before your custom animation will start working, you need to wire it up.
Replace MainViewController. But this is actually a good thing. Within the Storyboard, find the MenuViewController scene green. As usual, the animation begins with the ContainerView and the fromVC. To see the dismiss animator in action, wire it up to the appropriate transitioning delegate method. Build and run.The slide-out navigation panel allows users to slide content on or off screen.
How to Create Your Own Slide-Out Panel Navigation
The slide-out navigation panel design pattern lets developers add permanent navigation to their apps without taking up valuable screen real estate, since users can choose to reveal the navigation at any time, while still seeing their current context. You can find the views for the center, left and right view controllers in Main. So, feel free to take a look at the whole project. First order of business is placing CenterViewController inside the ContainerViewController as a child view controller.
Open ContainerViewController. Locate viewDidLoad and add the following properties right above it:. These two properties will hold both the centerViewController and its parent navigation controller. Add the following code inside viewDidLoadbeneath the call to super :.
Now to take care of the error, modify this class so it implements CenterViewControllerDelegate. Implementing these methods makes this class conform to CenterViewControllerDelegate. Now is a good time to check your progress. Build and run the app. You should see something similar to the screen below:. Yes, those buttons at the top will eventually bring you kitties and puppies. What better reason could there be for creating sliding navigation panels? First, to the left!
To expand the left panel, the user will tap on the Kitties button in the navigation bar. Open CenterViewController. In the interests of keeping this tutorial focused on the important stuff, the IBAction s and IBOutlet s are pre-connected for you in the storyboard.Roland versaworks download
However, to implement your DIY slide-out navigation panel, you need to understand how the buttons are configured. Notice there are already two IBAction methods, one for each of the buttons. As previously mentioned, the method is already hooked up to the Kitties button. This uses optional chaining to call toggleLeftPanel only if delegate has a value. You can see the definition of the delegate protocol at the bottom.
If you remember, when you set up the center view controller instance earlier, you set its delegate as the container view controller. Time to go and implement toggleLeftPanel. These will hold the current state of the side panels and the left side panel view controller itself:. You initialize currentState to.
First, this method checks whether the left side panel is already expanded. Next, you need to add the code to add the left panel to the view hierarchy. Add the following just below toggleLeftPanel :. This code first checks to see if the leftViewController property is nil. If it is, then it creates a new SidePanelViewController and sets its list of animals to display — in this case, cats!
This method adds the child view controller to the container view controller. This is the same as adding the center view controller earlier. Add the following constant below your other properties at the top of ContainerViewController :.
This value is the width, in points, of the center view controller left visible once it has animated off screen. This is where the actual animation happens.You'll learn how to define your custom container view that manages the center view and the side view, how to define a protocol in swift and how to define a custom table view cell. Leave blank the section called Main interface under the app configuration.
We'll use our custom container as a main interface. Let's now define the main view interface by going to the appdelegate. Here you'll edit the application function, the first function that is called as soon as the app is ready. Now create the required classes. The ContainerMainView is the main class that will manage everything and all the sub views.
Let's now move to the storyboard. Firstly let's disable the size classes feature. Next you've to select the UIViewController that has been already added by swift.
Under show attribute inspector turn off is initial view controller and put as a navigation bar the translucent navigation bar. If you want add also a UIImageView and set under the attribute inspector the aspect fill mode this allows the image to adapt in respect of the available sizes.
Add also the constraints to the UIImage. Let's define now the Side menu view. In the storyboard add a new UIViewController. Set the width of the table view to this is a bit smaller than the size of the menu - in this case. Add now to the table view the following constraint : width equal totop marginbottom margin and right margin. This view should look like this:. Create a new Swift File and call it common. Inside it define the protocol that will be used. This class will implement this protocol.
Closed self. Next define an array for the menu elements and set the data source and delegates. Finally the MainView class is defined. This class implements the SideMenuClick protocol for changing the background as soon as a click event on the side menu occured. About Contact. KaleidosBlog TechnoVision. This is the side menu for iOS that you'll create. Defining the layout in the storyboard Let's now move to the storyboard. In the screenshot below I've reported how the MainView should look like.
Leave a comment. How would you handle the instance where when the menu slides opened and the user clicks on a menu option that a different view not just the MainView get displayed.
Example you have the same 3 views you mentioned as: - ContainerView - SideView - MainView but now you have lets say an additional views like - ProfileView - SettingsView So the app starts up with the mainView being displayed and then the user slides the menu out and clicks on Profile which should display the profileView and if they slide out the menu and select the setting menu option it displays the menuView and if they open the menu and they hit the main option the mainView is displayed.
So in other words the menu option dictate which view to display and not how you currently have it where it just updates an image in the same view mainView each and every time!? Andrea - 02 December at Hi, thank you for your comment. You'll have two options: 1 as soon as you click on a menu item, you have to close the menu, and push in the navigation controller hierarchy the new view, be sure in this case to disable the menu sliding and reactivate as soon as the user go back to the main view 2 if you do not want to use the view hierarchy you have to dinamically load the view controller inside the "mainview" - so in this case as soon as you press on a menu item, the menu will be closed, the main view subviews will be removed, the new view controller will be added inside the mainview - in this second options in every view you still have the menu.
I am a little unclear on the steps to be taken for either option. Andrea - 02 December at Sure, I'll write a tutorial about that in these days with the two ways to change views. I'll write an email as soon as it is ready. I will be waiting with anticipationWhy to use a library everytime? Now we will create a Base UIViewController to use anywhere in the project which control the delegate of menu.
First we will create this 3 lines Drawer Icon via Code.Index of billions s3
If current view is open then we will not open it once again for that we have to check via Restoration Identifier. Now We will assign this drawer to any of the UIViewController We have to use only one method to add drawer slide menu self. I lose the menu image when instantiating to another navigationcontroller. The menu works but the image is gone? Do you have a solution? UINavigationController self.
Well that is just my problem, the menu works fine in all other viewcontrollers I added. Only the image 3 horizontal stripes is not visible. I can still tap it and the menu will slide in. But there is just no image. I must be missing something very basic… Maybe I should not use storyboard IDs, do you have an alternative way to push to another VC?
UISlider Tutorial and Example (Updated for 2018)
Thanks for the fast reply! Hi Ashish, Many thanks for your effort to publish that post. I like sliding menu. I only have 1 questions regarding the issue that has been mentioned in the comments. Do you have any resolution for it — the menu button image that disappear when moving to another controller.
Best regards, Ahmed. Thanks a lot.Create a new Xcode 10 project 2. Add the slider to the view 3. Attach the elements to IBOutlets 4. Connecting the Slider value changed event 5. Conclusion and Source Code. Start by going to Main. When you find it, click and drag it onto your view. Next, do the same thing with a UILabel. Search for it and then drag it onto your view. Go to Assistant Editor and make sure that you see your storyboard on the left side and ViewController. A blue line should follow your mouse cursor and when you release, a dialog will popup and ask you what to name your IBOutlet property.
At the end, your ViewController. Notice the two filled-in grey circles beside the two properties. A common mistake: If you made a mistake in connecting the elements or naming your properties and you want to re-do it, you can delete the property in the. In order to respond to event of the slider value changing, we have to hook up the event in the. Once again, we want to be in Assistant Editor view. Drag it to an empty space in between the override func and the closing curly brace of the class method such as in the screenshot below.
Run the app now and drag the slider thumb around. There you have it! Adding a slider and getting its value is pretty simple. Do you have any idea why? Hey Kamand, it looks like when you connected the IBOutlet property, you might have dragged and connected the wrong element!
Hey Sephethus, if the sliders are auto generated, then instead of hooking up an IBAction method through the storyboard, you would programmatically set the target method that the slider should call. Conclusion and Source Code 1. Do it for both. Connecting the Slider value changed event In order to respond to event of the slider value changing, we have to hook up the event in the.

You can install it with the following command:. Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. You can install Carthage with Homebrew using the following command:.
The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler. It is in early development, but SideMenu does support its use on supported platforms.
Once you have your Swift package set up, adding SideMenu as a dependency is as easy as adding it to the dependencies value of your Package.
Create a Navigation Controller for a side menu. Set up any Triggered Segues you want in that view controller. Set that button's Triggered Segues action to modally present the Navigation Controller from step 1.
To use gestures you have to use the SideMenuManager. In your AppDelegate do something like this:. To receive notifications when a menu is displayed from a view controller, have it adhere to the SideMenuNavigationControllerDelegate protocol:. If your view controller adheres to the protocol then the methods will be called automatically. For simplicity, SideMenuManager.
If you need to show a different SideMenu using gestures, such as from a modal view controller presented from a previous SideMenu, do the following:. Alternatively, you can set sideMenuManager from the view controller that segues to your SideMenuNavigationController:. Important: displaying SideMenu instances directly over each other is not supported. If you want to create your own custom presentation style, create a subclass of SideMenuPresentationStyle and set your menu's presentationStyle to it:.
