It opened and closed its first day of trading with a flat price. But Monday was a day of reckoning. The Street first reported that Amazon Technologies Inc. Knowing which stock to target, traders sent the Blue Apron price tumbling. By 1. 1 1. 9 AM, it was down 9. The ominous figure was 6. After hours trading showed the stock hovering in the same range. Blue Apron was already trying to break into a tough business and in its initial prospectus, it said that it had just enough cash and borrowing capacity for at least one year. Taking a 3. 5 percent hit to its stock price isnt going to make anything easier. Amazons price ticked up 1 percent to 1. The online retail giant is a killer when it comes to aging industries like selling books. But it still faces stiff competition from its contemporaries. As recently as December, analysts were signaling that Netflix should be terrified of Amazon Prime. That could still be the case, but Netflix posted huge numbers today. After blowing away new subscriber estimates, the streaming service saw its shares rise by 1. Bezos may have the supply chains and the willingness to reinvest profits, but he doesnt have Orange is the New Black. The Street via Bloomberg. In the last couple of months, Apple has released new features as part of i. OS 9 that allow a deeper integration between apps and the operating system. Among those features are Spotlight Search integration, Universal Links, and 3. D Touch for i. Phone 6. S and i. Phone 6. S Plus. Here at Flickr, we have added support for these new features and we have learned a few lessons that we would love to share. Spotlight Search. There are two different kinds of content that can be searched through Spotlight the kind that you explicitly index, and the kind that gets indexed based on the state your app is in. To explicitly index content, you use Core Spotlight, which lets you index multiple items at once. To index content related to your apps current state, you use NSUser. Activity when a piece of content becomes visible, you start an activity to make i. OS aware of this fact. OS can then determine which pieces of content are more frequently visited, and thus more relevant to the user. NSUser. Activity also allows us to mark certain items as public, which means that they might be shown to other i. OS users as well. For a better user experience, we index as much useful information as we can right off the bat. We prefetch all the users albums, groups, and people they follow, and add them to the search index using Core Spotlight. Indexing an item looks like this. Create the attribute set, which encapsulates the metadata of the item were indexing. CSSearchable. Item. Attribute. Set attribute. Set CSSearchable. Item. Attribute. Set alloc init. With. Item. Content. Type NSString k. UTType. Image. attribute. Set. title photo. Set. content. Description photo. Description. attribute. Set. keywords photo. Set. thumbnail. Data UIImage.

Content. Type domain. Identifier FLKCurrent. User. Search. Domain attribute. Set attribute. Set. CSSearchable. Index default. Searchable. Index index. Searchable. Items searchable. Item completion. Handler NSError Nullable error. Handle failures. Since we have multiple kinds of data photos, albums, and groups we had to create an identifier that is a combination of its type and its actual model ID. Many users will have a large amount of data to be fetched, so its important that we take measures to make sure that the app still performs well. Since searching is unlikely to happen right after the user opens the app thats when we start prefetching this data, if needed, all this work is performed by a low priority NSOperation. Queue. If we ever need to fetch images to be used as thumbnails, we request it with low priority NSURLSession. Download. Task. These kinds of measures ensure that we dont affect the performance of any operation or network request triggered by user actions, such as fetching new images and pages when scrolling through content. Flickr provides a huge amount of public content, including many amazing photos. If anybody searches for Northern Lights in Spotlight, shouldnt we show them our best Aurora Borealis photos For this public content photos, public groups, tags and so on we leverage NSUser. Activity, with its new search APIs, to make it all searchable when viewed. Heres an example. CSSearchable. Item. Attribute. Set ttribute. Set CSSearchable. Item. Attribute. Set alloc init. With. Item. Content. Type NSString k. UTType. Image. Setup attribute. Set the same way we did before. Set the related unique identifier, so it matches to any existing item indexed with Core Spotlight.

Activity and make it current. 2Nd Speech Center Keygen Download Free on this page. The more often a specific activity is made current, the more relevant i. OS considers it. In fact, the more often an activity is made current by any number of different users, the more relevant Apple considers it globally, and the more likely it will show up for other i. OS users as well provided its public. Until now weve only seen half the picture. Weve seen how to index things for Spotlight search when a user finally does search and taps on a result, how do we take them to the right place in our app Well get to this a bit later, but for now suffice it to say that youll get a call to the method application continue. User. Activity restoration. Handler to our application delegate. Its important to note that if we wanted to make use of the user. Info in the NSUser. Activity, i. OS wont give it back to you for free in this method. To get it, we have to make sure that we assigned an NSSet to the required. User. Info. Keys property of our NSUser. Activity when we created it. In their documentation, Apple also tells us that if you set the webpage. URL property when eligible. For. Search is YES, you need to make sure that youre pointing to the right web URL corresponding to your content, otherwise you might end up with duplicate results in Spotlight Apple crawls your site for content to surface in Spotlight, and if it finds the same content at a different URL itll think its a different piece of content. Universal Links. In order to support Universal Links, Apple requires that every domain supported by the app host an apple app site association file at its root. This is a JSON file that describes which relative paths in your domains can be handled by the app. When a user taps a link from another app in i. OS, if your app is able to handle that domain for a specific path, it will open your app and call application continue. User. Activity restoration. Handler. Otherwise your application wont be opened Safari will handle the URL instead. XXXXXXXXXX. com. some. This file has to be hosted on HTTPS with a valid certificate. Its MIME type needs to be applicationpkcs. No redirects are allowed when requesting the file. If the only intent is to support Universal Links, no further steps are required. But if youre also using this file to support Handoffs introduced in i. OS 8, then your file has to be CMS signed by a valid TLS certificate. In Flickr, we have a few different domains. That means that each one of flickr. JSON association file, whether or not they differ. In our case, the flic. URLs hence, its apple app site association is different than the others. On the client side, only a few steps are required to support Universal Links. First, Associated Domains must be enabled under the Capabilities tab of the apps target settings. For each supported domain, an entry applinks entry must be added. Here is how it looks for Flickr That is it. Now if someone receives a text message with a Flickr link, she will jump right to the Flickr app when she taps on it. Deep linking into the app. Great We have Flickr photos showing up as search results and Flickr URLs opening directly in our app. Now we just have to get the user to the proper place within the app. There are different entry points into our app, and we need to make the implementation consistent and avoid code duplication. OS has been supporting deep linking for a while already and so has Flickr. To support deep linking, apps could register to handle custom URLs meaning a custom scheme, such as myscheme mydata1.
