If set to nil or if <em>items</em> doesn't contain any photo with matching <em>identifier</em> , then the first photo in array will be selected.</li>     <li><em>maxItemsCount</em> — maximum number of photos that user is allowed to pick.</li>     <li><em>cropEnabled</em> — boolean flag indicating whether user can perform photo cropping.</li>     <li><em>cropCanvasSize</em> — maximum size of canvas when cropping photos. (see Memory constraints when cropping).</li>     <li><em>routerSeed</em> — routerSeed provided by Marshroute.</li>     <li><em>configuration</em> — closure that allows you to providemodule's additional parameters.</li>    </ul>    <p>Additional parameters of MediaPicker module</p>    <p>Additional parameters is described in protocol MediaPickerModule :</p>    <ul>     <li>setContinueButtonTitle(_:) and setContinueButtonEnabled(_:) allow to customize "Continue" button text and availability.</li>     <li>onItemsAdd is called when user picks items from photo library or takes a new photo using camera.</li>     <li>onItemUpdate is called after user performed cropping.</li>     <li>onItemRemove is called when user deletes photo.</li>     <li>onFinish and onCancel is called when user taps Continue and Close respectively.</li>    </ul>    <p>Memory constraints when cropping</p>    <p>When cropping photo on devices with low RAM capacity your application can crash due to memory warning. It happens because in order to perform actual cropping we need to put a bitmap of the original photo in memory. To descrease a chance of crashing on older devices (such as iPhone 4 or 4s) we can scale the source photo beforehand so that it takes up less space in memory. <em>cropCanvasSize</em> is used for that. It specifies the size of the photo we should be targeting when scaling.</p>    <h3>Presenting photo library</h3>    <p>Initialize module assembly using Paparazzo.AssemblyFactory (or Paparazzo.MarshrouteAssemblyFactory if you use Marshroute):</p>    <pre>  <code class="language-swift">let factory = Paparazzo.AssemblyFactory()  let assembly = factory.photoLibraryAssembly()</code></pre>    <p>Create view controller using assembly's module method:</p>    <pre>  <code class="language-swift">let viewController = assembly.module(      selectedItems: selectedItems,      maxSelectedItemsCount: maxSelectedItemsCount,      routerSeed: routerSeed,    // omit this parameter if you're using AssemblyFactory      configuration: configuration  )</code></pre>    <ul>     <li><em>selectedItems</em> — preselected photos (or nil ).</li>     <li><em>maxItemsCount</em> — maximum number of photos that user is allowed to pick.</li>     <li><em>routerSeed</em> — routerSeed provided by Marshroute.</li>     <li><em>configuration</em> — closure used to provide additional module setup.</li>    </ul>    <h3>UI Customization</h3>    <p>You can customize colors, fonts and icons used in photo picker. Just pass an instance of PaparazzoUITheme to the initializer of assembly factory.</p>    <pre>  <code class="language-swift">var theme = PaparazzoUITheme()  theme.shutterButtonColor = .blue  theme.accessDeniedTitleFont = .boldSystemFont(ofSize: 17)  theme.accessDeniedMessageFont = .systemFont(ofSize: 17)  theme.accessDeniedButtonFont = .systemFont(ofSize: 17)  theme.cameraContinueButtonTitleFont = .systemFont(ofSize: 17)  theme.cancelRotationTitleFont = .boldSystemFont(ofSize: 14)    let assemblyFactory = Paparazzo.AssemblyFactory(theme: theme)</code></pre>    <h2>Author</h2>    <p>Andrey Yutkin ( <a href="/misc/goto?guid=4959739926310581500" rel="nofollow,noindex">ayutkin@avito.ru</a> )</p>    <h2>License</h2>    <p>MIT</p>    <p> </p>
