NASAApp is iOS application using NASA API's', it's universal, for iPad/iPhone with iOS 9.0 atleast. Application have 3(4) main features.
APOD is Astronomy Picture of the Day. On the initial screen when apps loaded you can see APOD for yesterday. You can choose any correct date using picker view on the same screen. You can see images media and youtube videos media as well. Every APOD have own explanation, which you can see pressing button "Explanation" on the bottom toolbar. Also you can save presented image in photo library (app will ask permissions for using photo library offcourse).
Using NASA Mars Imagery API you can get images asset for one of three current Mars rovers (Curiosity, Opportunity, Spirit), for selected or for all cameras, for selected Sol (Mars day). After that you can select any presented image for adding text on it, saving in photo library or sending it by email.
Also you can apply one or some filters from filters-preset-buttons.
Using NASA Earth Landsat8 Imagery API you can get images of choosen location. You can choose location using your current position, or by entered latitude+longitude values or by entering address or placemark of needed location. After location is chosen you see image asset for it, taken by Landsat8 (usually it take a pic of location every 16 days), so you can choose any and see it on datail view. You can save this image in photolibrary or send it by email as well.
There is one more half-implemented feature. On the 'Sounds' screen you can enter search phrase and get a list of available space sounds in the table view. There should be option to play these sounds, but application have to be authenticated by soundcloud.com service for that, but it does not yet. So you can not play sound right now.
- Nuke - A powerful image loading and caching framework which allows for hassle-free image loading in your app - often in one line of code.
- Preheat - Automates preheating (prefetching) of content in UITableView and UICollectionView. Both libraries was installed manually, very detailed installation guide
If you prefer not to use either of the aforementioned dependency managers, you can integrate Nuke into your project manually.
Embedded Framework
Open up Terminal, cd into your top-level project directory, and run the following command "if" your project is not initialized as a git repository:
$ git init
Add Nuke as a git submodule by running the following command:
$ git submodule add https://github.com/kean/Nuke.git
Open the new Nuke folder, and drag the Nuke.xcodeproj into the Project Navigator of your application's Xcode project. It should appear nested underneath your application's blue project icon. Whether it is above or below all the other Xcode groups does not matter. Select the Nuke.xcodeproj in the Project Navigator and verify the deployment target matches that of your application target. Next, select your application project in the Project Navigator (blue project icon) to navigate to the target configuration window and select the application target under the "Targets" heading in the sidebar. In the tab bar at the top of that window, open the "General" panel. Click on the + button under the "Embedded Binaries" section. You will see two different Nuke.xcodeproj folders each with two different versions of the Nuke.framework nested inside a Products folder. It does not matter which Products folder you choose from, but it does matter whether you choose the top or bottom Nuke.framework. Select the top Nuke.framework for iOS and the bottom one for OS X. You can verify which one you selected by inspecting the build log for your project. The build target for Nuke will be listed as either Nuke iOS, Nuke macOS, Nuke tvOS or Nuke watchOS. And that's it! The Nuke.framework is automagically added as a target dependency, linked framework and embedded framework in a copy files build phase which is all you need to build on the simulator and a device.
For using it in the project you just have to import needed library, like "#import Nuke". Nuke used in project for fast loading images with double-layers cache support. Preheat used for preheatting images when loading big array of images in collection view (in RoverPhotosCollectionViewController)
