This is a cool effect. 6 | 7 | And it's really easy to build in iOS using Auto Layout. I want to 8 | write about this because the effect is so simple, and Auto Layout 9 | makes its implementation so elegant, that I think you ought to know 10 | about it. 11 | 12 | If you want to follow along you can [clone the demo project at our 13 | starting point](https://github.com/TwoLivesLeft/StretchyLayout/tree/Step-1) 14 | then implement this effect as you read along. You'll need Xcode 9 as we're 15 | going all-in on iOS 11 for this example. 16 | 17 | ``` 18 | git clone https://github.com/TwoLivesLeft/StretchyLayout.git 19 | cd StretchyLayout 20 | git checkout Step-1 21 | ``` 22 | 23 | Here's how we'll do this 24 | 25 | * Start with the basic non-stretchy app 26 | * Modify the view hierarchy to add the necessary constraints to 27 | make it stretchy 28 | * Add polish to the app 29 | 30 | ## The non-Stretchy App 31 | 32 | ![Initial View Hierarchy](Article/InitialViewHierarchy.png) 33 | 34 | Here's the view hierarchy for the basic version of the app. You can see it has 35 | three main views. The header `UIImageView`, the container for the text, and the 36 | long `UILabel` containing our text content. The bright red lines represent our 37 | Auto Layout constraints. There's also a `UIScrollView` and the root view of our 38 | view controller. 39 | 40 | We're going to build this using an Auto Layout framework called 41 | [SnapKit](http://snapkit.io). SnapKit is a simple iOS framework that makes 42 | Apple's Auto Layout API... sane. It's dead simple to use and makes 43 | programming with Auto Layout genuinely pleasurable. 44 | 45 | Most of the code will live in `viewDidLoad` of our 46 | `StretchyViewController` class. Below you can see how the initial 47 | constraints are set. 48 | 49 | Our views are declared as private members: 50 | 51 | ``` 52 | private let scrollView = UIScrollView() 53 | private let infoText = UILabel() 54 | private let imageView = UIImageView() 55 | ``` 56 | 57 | And our view controller's view has a scroll view as its first subview, followed 58 | by the text and image views (as well as a backing view which provides us with 59 | the red background behind the text). 60 | 61 | ``` 62 | //Pin the edges of the scroll view to 63 | // our view controller's view 64 | scrollView.snp.makeConstraints { 65 | make in 66 | 67 | make.edges.equalTo(view) 68 | } 69 | 70 | //Pin the top of our image view to the scroll view 71 | // pin the left and right to the view controller's view 72 | // give it an aspect ratio constraint by constraining 73 | // its height to its width with a multiplier 74 | imageView.snp.makeConstraints { 75 | make in 76 | 77 | make.top.equalTo(scrollView) 78 | make.left.right.equalTo(view) 79 | make.height.equalTo(imageView.snp.width).multipliedBy(0.7) 80 | } 81 | 82 | //Pin the backing view below the image view and to the 83 | // bottom of the scroll view 84 | textContainer.snp.makeConstraints { 85 | make in 86 | 87 | make.top.equalTo(imageView.snp.bottom) 88 | make.left.right.equalTo(view) 89 | make.bottom.equalTo(scrollView) 90 | } 91 | 92 | //Pin the edges of the text to the text container view, this 93 | // will force the text container to grow to encompass the 94 | // text's height 95 | infoText.snp.makeConstraints { 96 | make in 97 | 98 | make.edges.equalTo(textContainer).inset(14) 99 | } 100 | ``` 101 | 102 | > Note: To get the code at this point do `git checkout Step-1` 103 | 104 | ## A Brief Aside 105 | 106 | You notice we used SnapKit above. SnapKit is great; here's a primer on 107 | how it works. 108 | 109 | You access the `snp` member object on any `UIView`. 110 | 111 | You call `makeConstraints` which accepts a closure, the closure is given a 112 | `ConstraintMaker` object (called `make` here). 113 | 114 | You then use the `make` object to pin edges or anchors of one view to any 115 | other view, layout guide, or constant. 116 | 117 | ``` 118 | myView.snp.makeConstraints { 119 | make in 120 | 121 | make.edges.equalTo(view) 122 | } 123 | ``` 124 | 125 | This will pin the edges of `myView` to the edges of `view`. 126 | 127 | It's readable and concise. *Use this instead of the default Auto Layout API.* 128 | 129 | ## Making it Stretchy 130 | 131 | So how do we go from this, to this? 132 | 133 | ![Comparison](Article/ScrollComparison.gif) 134 | 135 | Important to this effect is that Auto Layout will solve constraints 136 | regardless of whether your views are siblings or elsewhere in the hierarchy. 137 | As long as they have a common ancestor. 138 | 139 | But key is that views within scroll views can be constrained to views 140 | outside of scroll views. That's how we will make this work. 141 | 142 | ![Stretchy View Hierarchy](Article/StretchyViewHierarchy.png) 143 | 144 | In the above diagram the bright red lines represent our constraints. Note how 145 | the top of the image view is now pinned all the way back — outside the scroll 146 | view — to the top of the root view. But its bottom is pinned to the bottom of 147 | the image container view, which *is* inside the scroll view. This means that 148 | when the scroll view scrolls, our image view will stretch to satisfy its 149 | constraints. 150 | 151 | So for our first step we'll replace our `UIImageView` with an empty container 152 | view. 153 | 154 | ``` 155 | let imageContainer = UIView() 156 | imageContainer.backgroundColor = .darkGray 157 | scrollView.addSubview(imageContainer) 158 | 159 | imageContainer.snp.makeConstraints { 160 | make in 161 | 162 | make.top.equalTo(scrollView) 163 | make.left.right.equalTo(view) 164 | make.height.equalTo(imageContainer.snp.width).multipliedBy(0.7) 165 | } 166 | ``` 167 | 168 | Then we'll add our image view as a subview of our scroll view. But we're going 169 | to pin its top edge to our *view's* top edge — not our scroll view's top (the 170 | container we just added above is pinned to our scroll view's top edge). 171 | 172 | ``` 173 | scrollView.addSubview(imageView) 174 | 175 | imageView.snp.makeConstraints { 176 | make in 177 | 178 | make.left.right.equalTo(imageContainer) 179 | 180 | //** These are the key lines! ** 181 | make.top.equalTo(view) 182 | make.bottom.equalTo(imageContainer.snp.bottom) 183 | } 184 | ``` 185 | 186 | Above you can see the lines that make this work. Our image container view 187 | scrolls exactly how the original non-stretchy app scrolled. But we've added 188 | our actual image view above that container, and then we've pinned its bottom 189 | to the container bottom, but its **top** is pinned to the view controller's 190 | view. 191 | 192 | This means that when you drag down in the scroll view the top of the image 193 | "sticks" to the top of the screen and the whole image just gets bigger. And 194 | because we're using: 195 | 196 | `imageView.contentMode = .scaleAspectFill` 197 | 198 | We're going to see the image content scale up within the image view as we 199 | over-scroll the scroll view. 200 | 201 | > Note: To get the code at this point do `git checkout Step-2` 202 | 203 | ### But There's a Bug 204 | 205 | If you run this code, dragging down on the screen with your finger produces 206 | the desired effect: the image scales up and bounces back. But if you scroll up 207 | to read the text ... well, you'll realise that you can't. 208 | 209 | ![Scroll Bug](Article/ScrollBug.gif) 210 | 211 | Why? 212 | 213 | Because when we scroll up we are compressing the `UIImageView` into a 214 | zero-height line. Its top *must* be equal to the view's top, and its bottom 215 | *must* be equal to the text backing view's top. So this means the scroll view 216 | will continue to "scroll," but we won't see the changes because the backing 217 | view is jammed up against the image view, which is refusing to move above the 218 | top of the root view despite the scroll view scrolling. 219 | 220 | Auto Layout is technically solving our constraints, but it's not what we want. 221 | 222 | ### Fixing the bug 223 | 224 | We have to change how we constrain the image view. Here's the change: 225 | 226 | ``` 227 | imageView.snp.makeConstraints { 228 | make in 229 | 230 | make.left.right.equalTo(imageContainer) 231 | 232 | //** Note the priorities 233 | make.top.equalTo(view).priority(.high) 234 | 235 | //** We add a height constraint too 236 | make.height.greaterThanOrEqualTo(imageContainer.snp.height).priority(.required) 237 | 238 | //** And keep the bottom constraint 239 | make.bottom.equalTo(imageContainer.snp.bottom) 240 | } 241 | ``` 242 | 243 | Notice how we now have a top constraint, a bottom constraint, *and* a height 244 | constraint? This is one of the awesome things about Auto Layout: we can have 245 | conflicting constraints and they will be broken in priority order. 246 | This is necessary to achieve the effect we want. 247 | 248 | First we keep our original constraint. The top of our image view is pinned to 249 | the top of our view. We give this a priority of `.high`. 250 | 251 | We then add an additional constraint: the height of our image must be greater 252 | than or equal to the height of the image container behind it (recall our image 253 | container has the aspect ratio constraint). This has a `.required` priority. 254 | 255 | So what happens when we scroll up? 256 | 257 | Well, the image *can't* get smaller. Our height constraint has a higher priority 258 | than the top constraint. So when we scroll up Auto Layout will break the 259 | lowest priority constraint in order to solve the system. It will break the top 260 | constraint and our scrolling behaviour will revert to normal, allowing us 261 | to scroll up and read the text. 262 | 263 | (Note that you can also remove the height constraint in this instance and simply 264 | set the top constraint priority to `.high`. This will allow iOS to break the 265 | top constraint *and* compress the image view to zero height. Given the 266 | `.scaleAspectFill` content mode, this creates a parallax-like effect. Try it 267 | out. You might prefer the way it looks.) 268 | 269 | > Note: To get the code at this point do `git checkout Step-3` 270 | 271 | ## Polishing the Details 272 | 273 | There are three jarring problems we should fix while we're here. 274 | 275 | #### 1. Text Over-Scrolling 276 | 277 | If we over-scroll past the bottom of the view we get to see the ugly 278 | grey background of our view controller. We can use the exact same method to 279 | stretch our backing view out when we over-scroll past the bottom of the view. 280 | 281 | ![Text Overscroll](Article/TextOverscroll.gif) 282 | 283 | I won't go into the code as it's basically the same technique as the image 284 | view above. We add an additional text backing view behind our text container, 285 | and then pin its bottom edge to the root view's bottom edge. 286 | 287 | > Note: To get the code at this point do `git checkout Step-4` 288 | 289 | #### 2. Respecting the Safe Area 290 | 291 | On iPhone X our text overlaps the home indicator. We disabled the 292 | automatic content inset adjustment of our scroll view in order to let our image 293 | content go right to the top of the screen. So we'll have to manually handle 294 | the bottom inset using the new `safeAreaInsets` property in iOS 11. 295 | 296 | We also want to use `safeAreaInsets` to adjust our scroll 297 | view's scrolling indicators so they don't run into the curved edges of the 298 | screen on iPhone X. 299 | 300 | To fix these two issues we'll override `viewDidLayoutSubviews` and manually 301 | set the bottom inset of the scroll view. iOS 11 would normally do this for 302 | us automatically, but we *don't* want to inset the top, because we want our 303 | header image flush behind the status bar. 304 | 305 | We have told iOS 11 not to touch our scroll view by setting its 306 | `contentInsetAdjustmentBehavior` to `.never`. 307 | 308 | ``` 309 | override func viewDidLayoutSubviews() { 310 | super.viewDidLayoutSubviews() 311 | 312 | //** We want the scroll indicators to use all safe area insets 313 | scrollView.scrollIndicatorInsets = view.safeAreaInsets 314 | 315 | //** But we want the actual content inset to just respect the bottom safe inset 316 | scrollView.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: view.safeAreaInsets.bottom, right: 0) 317 | } 318 | ``` 319 | 320 | This gives us the following appearance when scrolled all the way to the end. 321 | Note that the scroll indicator is no longer lost behind the curve, and we get 322 | much more space above the home indicator. 323 | 324 | ![Fixed Safe Area](Article/FixedSafeArea.png) 325 | 326 | > Note: To get the code at this point do `git checkout Step-5` 327 | 328 | #### 3. Hiding the Status Bar When Needed 329 | 330 | Our text is overlapping the status bar when we scroll up. This 331 | looks gross. 332 | 333 | ![Status Bar Overlap](Article/StatusBarOverlap.png) 334 | 335 | Let's hide the status bar with a cool animation when the user 336 | scrolls the text into the status bar area. It's quite easy to detect this and 337 | I think the effect looks great. 338 | 339 | ![Status Bar Hide](Article/StatusBarHide.gif) 340 | 341 | How do we do this? 342 | 343 | * We convert the `textContainer`'s rect to screen coordinates 344 | * We check if the minimum Y of that frame is less than the view's top safe area 345 | inset (this indicates the text container is moving into the status bar area) 346 | * If so, we hide the status bar. If not, we show the status bar. 347 | 348 | We perform this check in the `scrollViewDidScroll(_:)` method of the 349 | `UIScrollViewDelegate`. (So we make our `StretchyViewController` implement this 350 | delegate and set itself as the delegate for its scroll view.) 351 | 352 | Here's the code for the status bar check: 353 | 354 | ``` 355 | //MARK: - Scroll View Delegate 356 | 357 | private var previousStatusBarHidden = false 358 | 359 | func scrollViewDidScroll(_ scrollView: UIScrollView) { 360 | //** We keep the previous status bar hidden state so that 361 | // we're not triggering an implicit animation block for every frame 362 | // in which the scroll view scrolls 363 | if previousStatusBarHidden != shouldHideStatusBar { 364 | 365 | UIView.animate(withDuration: 0.2, animations: { 366 | self.setNeedsStatusBarAppearanceUpdate() 367 | }) 368 | 369 | previousStatusBarHidden = shouldHideStatusBar 370 | } 371 | } 372 | 373 | //MARK: - Status Bar Appearance 374 | 375 | override var preferredStatusBarUpdateAnimation: UIStatusBarAnimation { 376 | //** We use the slide animation because it works well with scrolling 377 | return .slide 378 | } 379 | 380 | override var prefersStatusBarHidden: Bool { 381 | return shouldHideStatusBar 382 | } 383 | 384 | private var shouldHideStatusBar: Bool { 385 | //** Here's where we calculate if our text container 386 | // is going to hit the top safe area 387 | let frame = textContainer.convert(textContainer.bounds, to: nil) 388 | return frame.minY < view.safeAreaInsets.top 389 | } 390 | ``` 391 | 392 | > Note: To get the code at this point do `git checkout Step-6` 393 | 394 | ## What We Covered 395 | 396 | * You can pin pretty much anything to anything else and your views will 397 | stretch to satisfy your constraints 398 | * Even if you're scrolling 399 | * Constraints are broken in priority order, so don't be afraid to experiment 400 | with conflicting constraints 401 | * Use SnapKit 402 | -------------------------------------------------------------------------------- /StretchyLayouts.xcodeproj/project.pbxproj: -------------------------------------------------------------------------------- 1 | // !$*UTF8*$! 2 | { 3 | archiveVersion = 1;
