We’re going to exploit this to show any attachments for the open be aware rfile. NSCollectionView is supplied by means of AppKit to show a grid of different perspectives. each one view it monitors is controlled through an NSCollectionViewItem. To create the gathering view, we additionally have to create the view for every mobile. We purely have to create the sort of perspectives — the gathering view will create and deal with a number of copies of them, one for every attachment within the files. notice the nearest identical for iOS is a UICollectionView, which we’ll use in a while, in “Collection Views”. determine 6-2. discovering the NSCollectionView Resize the gathering view to fill the margin underneath the textual content view, yet go away a few area at the correct hand facet (see determine 6-3). determine 6-3. including the gathering view pick out the gathering view and open the Attributes Inspector. within the structure techniques, switch it to circulate, on the way to create a pleasant, easy, linear structure for our attachments. pick out either the textual content view and the gathering view. Open the Editor menu, and select unravel automobile structure concerns, and select Reset to recommended Constraints. Open record. rapid within the Assistant. carry down the keep an eye on key, and drag from the gathering view into the rfile classification.

We extra a set view to our interface after which we used the integrated instrument to mend the restrictions on our interface. subsequent, we created an outlet for the gathering that will discuss with it in our code. ultimately, we connected the delegate and dataSource homes of the gathering view to our rfile. rapid category. We’ve performed all of this for you to discuss with and configure the gathering view in our code. Document-Filetype-Extension UI subsequent, we have to layout the view that might be used for every attachment within the assortment view. while, we’ll create a brand new classification that may act because the supervisor for the cell’s view. We won’t be including any code to this category without delay, however it saves a bit time to do it now instead of to create the dossier later. Create a brand new Cocoa type named AttachmentCell by way of going to File→New→File within the menu or by way of urgent ⌘-N. Make it a subclass of NSCollectionViewItem, and switch on “Also create XIB dossier for person interface,” as proven in determine 6-4. determine 6-4. including the AttachmentCell Open the newly created AttachmentCell. xib. visit the article library, and look for assortment View merchandise (Figure 6-5).
