The App Screenshot Design Guide teaches you how to create awesome screenshots using free design resources and tools. Plus, you will get the full source of two extra apps we are currently building. The other is a subscription app that keeps track of your subscription spending.
You're given the right to modify the source code and use them in your own projects. What people say about us "This book got me an internship and a job.
Best money I ever spent!! To me, and a lot of developers, your talent, knowledge, expertise and willingness to share have been simply a godsend. I bought this book and played with the code. I am now absorbing what I learned and am in the process of creating an app that I will put on the app store. This was my breakthrough. Just awesome. Your books saved my life. They're the best explained programming books I've ever read in my 10 years of programming.
They're so easy to understand and they hit everything. I will never thank you enough for writing the books and I owe you a lot. I am an experienced developer in another language and this book was exactly what was needed. It showed the idea behind iOS user interface and step by step it was taking you deeper. I strongly advice it for developer who have some background with developing in another environment and wants to learn swift.
The flow, the videos, the content, everything just makes it damn easy to learn and get started with iOS programming. Also, really appreciate the updates you keep doing, this is more of a living book rather a hard printed book frozen in time. Just awesome - you are giving an opportunity to several wannabes who would not have been! Keep going and all the best! But my biggest and most steady progress has been using this course material.
I'm not sure why it's clicking now more than before, but the way the course is structured just makes sense to me. And what I really love is it's project based learning approach. You actually make things as you learn, and by doing so you start to get those "ah ha" moments. There's nothing more exciting than figuring something out that at first you just couldn't get your head around.
As a high school AP computer science teacher I work mainly with Java but I also teach several other programming languages so I tend to keep a large library of books on-hand. While many of the other books and online video tutorials I purchased these past years were very good, I found AppCoda's to be far above all others. Simon has a way of presenting a topic in such a manner where I felt he was teaching me in a classroom environment rather than just me reading words on a screen.
We will then send you a sample book with page of free content. Starting by creating an app prototype, we will add one feature at a time and you will have a real app after going through the course.

The vertical spacing constraint is missing between the "Calculate Tip" button and the box image around the total. If you look on the hidden Auto Layout panel, it looks like everything is broken. Without this one constraint, none of the layout rules make sense. Adding it back fixes every single error. Broken Rules When you have layout errors, your views, labels, and images will not appear where you expect.
The iPhone will have to break one of your rules, or it might not have enough rules to describe the position and size of everything in your UI. Work in One Direction You should start top to bottom, and then move left to right. When you haven't defined everything from top to bottom, there are still missing constraints red , but you shouldn't worry yet.
Layout errors red are common when you are designing the interface. They should disappear when you finish, otherwise you have a problem.
Imagine Auto Layout like directions in a recipe. The dish is not complete until you follow all of the steps.
It takes time to do each step, and you won't be able to judge the final result until you finish each step. The same concept applies to Auto Layout: You need to describe all the vertical rules before the iPhone knows how to position your UI vertically.
You need to describe all the horizontal rules before your iPhone knows how to position your UI horizontally. For beginners the visual feedback can be confusing when you haven't finished adding all the layout rules. The more you practice Auto Layout the easier it is to understand. Stop reading this guide and try it on a test app. Create a new Xcode project and add some images, buttons, and labels.

Workflow: Structural Layout Add constraints to the main content regions first to create your structure. Work top to bottom for anything UI element that will impact the overall height structural. Work right to left for anything that will impact the overall width or horizontal placement structural. The Light at the End of the Tunnel UI in progress is going to be hard to tell if it's done, since you need to provide all of the rules in both a vertical and horizontal directions. Keep on adding rules for each of the structural UI elements.
Until you finish describing the position and size of your UI elements in a complete area, or subregion you will still see lots of red and blue. Don't worry if you see orange, it just means you may have nudged a view. If you get stuck and it doesn't look right, undo the change and try it again. And if you get really stuck, start over.
I do this all the time, don't be afraid to learn from your mistakes by doing it again. The more you practice setting up layout constraints, the more comfortable you will become.
You will only see generic errors about ambiguous constraints, but it won't always tell you specifics. Clicking the Warning sign on the top right corner of your Storyboard or. Depending on the panels you have open, you might not even the hidden layout error panel.
Open your Storyboard file. Show the Document Outline with your list of view controllers Bottom left corner of Storyboard file. Click on each screen View Controller. Click on the tiny red or orange arrow next to the title Read each hidden error message including the hover tips to help you fix the problems.
If you don't understand the error, do a Google search with the exact message. Seeing the actual warnings makes it a lot easier to figure out what's missing from your layout constraints. The next background color trick is something I use all the time. When you test your interface on large or small devices, the fastest way to see if your structure layout constraints are working is to change the background colors from Default clear or white to any color.
When I change colors for views that are touching adjacent , I use different colors for each view. That way you can see the edges and verify they are stretching or compressing correctly.
When you finish with your layout constraints, and you're satisfied that they behave correctly with the different iPhone simulators, you can revert the colors back to the Default color. Any time something weird happens after I've tweaked a layout, I'll change the background color of the surrounding elements to fix the bug.
You can use this same trick for image graphics when you create custom IBDesignable subviews. One version of the exported images will be "rainbow" colors and the other will be the final color of the app's theme.
Working productively with Auto Layout requires optimizing your mouse clicks and interactions. However, the context sensitive menu behavior is not helpful.
If you drag left or right you're wasting precious time and doing a lot of extra work. The context sensitive menu tries to only show you the constraints that you might want in a vertical or horizontal direction.
However, many times it will hide the actual constraints you need. To get around this quirk Please report it to Apple , you will need to drag diagonally. Many times the leading or trailing edge constraints are hidden if you just drag horizontally.
The Shift Key Modifier When you use the context sensitive right-click and drag method of adding Auto Layout constraints, you can save mouse clicks by using the Shift key modifier. After you click and drag, hold down the Shift key as you select multiple constraints to add. Make sure you click the button "Add Constraints" to add the constraints, otherwise you'll need to do it all over again, since they won't add if you click elsewhere on your Storyboard canvas.
You cannot add all the layout constraints from the canvas. Adding Difficult Constraints You will need to use the Document Outline on the left of your Storyboard to add constraints using the click and drag method.
Adding layout constraints can be tricky with a complex layout. If layers are on top of each other, you may have trouble connecting constraints from the visual canvas. If you need to add structural constraints between your "Top View" and the top margin, there's no way to add that constraint on the canvas.
Again, hold shift after dragging to add the leading, top, and trailing constraints in one go. It might seem that your constraints aren't working, when in fact they are.
If you work with images the next tip will save you time. Not knowing about the Content Mode setting can make your Auto Layout constraints look wrong, and will leave you frustrated.
The content in a UIStackView needs to be similar i. But if you haven't spent the extra effort to create those "UI widgets", it might be the wrong solution for your UI layout. You can learn how to create a an IBDesignable class here. From working with many beginner iPhone developers, I believe that you should start with manually laying out all the constraints to understand the behavior or UI elements and Auto Layout.
Part of translating a design into a responsive iPhone app layout requires graphics that can resize without visual artifacts. A responsive app requires you to think in terms of stretching in either the vertical or horizontal directions or both.
Buttons are typically stretched horizontally in apps, while cover photos might be stretched both vertically and horizontally to fill the space. If you have a custom graphic for a callout widget, you might want to maintain an aspect ratio, yet support growing or shrinking the graphic and related labels based on the screen width or height. Resizable graphics are easy if the design graphic is a solid color. Resizing a button graphic with a gradient limits you to a horizontal direction, or you'll see the stretch skew your gradient colors and your rectangle's corner radius.
Resizing a button graphic that isn't designed to stretch with cause discoloration and graphics artifacts, which makes your UI look strange Visual artifacts distract from the user experience. Stretch Correctly with Image Slicing Xcode has built in support for slicing images to make them resizable.
After you import an image into the Assets Catalog Assets. Click on "Show Slicing" to enable slicing mode. Enable slicing on each image that needs to be stretched by clicking on "Start Slicing" button.
Choose between horizontal, vertical, or both horizontal and vertical slicing. Keep in mind how your graphic is designed in order to make it stretch. The above "Tip Callout" image will only look good stretched vertical. If you stretch the "Tip Callout" image horizontally the bottom arrow will be off to a side, or skewed. If you want to make a button with a vertical gradient, you can use the asset catalog to define the end caps, which may have a corner radius.
It's important to give your end caps a big enough margin for your corner radius. Otherwise you'll see graphics artifacts when the image is stretched on iPhone.
I generally set it to the corner radius size. Next you define the region that will either stretch or tile when the button grows or shrinks. Optionally, you can exclude part of the button graphic so that you can support smaller sizes. You can skip this by making the exclude region 0 points wide.
The width of your graphic will determine how wide the button's intrinsic or default size appears on the screen Storyboard canvas. Stretchable graphics can always get bigger, but they cannot get smaller than their intrinsic size without visual artifacts. Make sure you describe all the horizontal and vertical constraints to pin the graphics to the edges, and to enable equal resizing.
You'll need to write some code to load the UIView from the.
Advanced Image Resizing To achieve some visual affects you will need to break apart a design element into multiple images. When you look at a graphic, there may be embellishments or frills that need to stay in specific positions. For example, with this tip calculator callout, you want the bottom arrow to stay centered. If the graphic resized using one of the sides, the arrow would be aligned on the a side, and it won't align to the label that is centered below the graphic.
You have a visual disconnect that is very distracting for the user, and that doesn't match your design. Break Down Design Elements Into Resizable Parts To achieve some visual effects you need to separate a design element into it's components that can be stretched with Auto Layout constraints either in Storyboard files or programmatically. Compare the colored borders to the final composition to see how the graphics fit together.
macOS Development for Beginners: Part 1
Some elements will be static sizes like the arrow and the left and right edges of the rounded rectangle. If you were to stretch these elements it will distort the arrow or the corner radius.
Reference the colored composition above to the parts. In the horizontal direction, I only want to stretch a portion of the horizontal bar that's on both the left and right sides of the arrow. The stretch region will need to stretch equally on both sides, or the arrow will be off center. Since I'm using a rounded rectangle, the flat middle portion will also need to stretch in the center of the graphic. Xcode's slicing will make this work with minimal effort. Tip 1: Show the bounds of each image when working with your Storyboard or.
These are good places to practice Auto Layout. It is adaptive and can stretch or shrink to different device sizes with the proper Auto Layout constraints.
After the auto layout constraints are added, you can swap out the colored variations of the view with the white and gray style with a corner radius of 4. Layer Breakdown Stretchable rounded rectangle Left and right end caps Arrow centered on top of rectangle Left stretchable region pinned a fixed distance from left edge and to the left edge of the arrow Right stretchable region pinned a fixed distance from right edge, and to the right edge of the arrow Using a edge inset of 5 on all sides enables the graphic to resize without any distortions with the 4 point corner radius.
Xcode Asset Catalog Effect Breakdown White Resizable rectangle with corner radius of 4 points right click to download this image and try it. Enable horizontal Asset Catalog slicing inset 4 points on left and right with center excluded. Advanced Constraints Editor When you use the right-click and drag method to add constraints or the align and pin buttons Xcode will sometimes add the wrong constraint.
You can edit the details of any constraints using the constraint options on the "Measurement" panel on the right side.While this guide only covers how to use Xcode, you can get an overall view of how to make iOS apps by reading my How to Make an App with No Programming Experience guide.
