If you don’t like the grey oder white color, you can also set a custom color. For that you can use the property color , which is an UIColor :

To give you a little more space to work with, click the white handle at the bottom of the view and drag it down, making the view 95 pixels tall. (Or, you can set the size for the view explicitly via the Size Inspector.)

It's been a while since you posted this question, so I'm not sure if you've found the answer you're looking for.

As you can see this is pretty simple. But let’s break it down to see what we really need, and how we can achieve this effect.

This view can be built inside of your storyboard and connected to its own class. Choose File\New\File…, choose the iOS\Source\Cocoa Touch Class template and click Next. Name the class FlickrPhotoHeaderView making it a subclass of UICollectionReusableView. Click Next and then Create to save the file.

First, this code creates an array of UIImage objects from the FlickrPhoto ‘s thumbnails. The UIImage array is much more convenient, as we can simply pass it to a UIActivityViewController. The UIActivityViewController will show the user any image sharing services or actions available on the device: iMessage, Mail, Print, etc. You simply present your UIActivityViewController from within a popover (because this is an iPad app), and let the user take care of the rest!

Prior to iOS 9, Collection View was sorely missing one feature that its cousin Table View has had for a long time: easy cell reordering. Thankfully, this is no longer the case, and it will be especially easy for you to implement it in this project because you are using a Collection View Controller.

In a future post, we’ll be showing how to implement another key component of mobile user experience, that use pretty much the same code. We are talking about the Activity Indicators. Meanwhile, have fun developing these awesome bars :).

After we got the bezier path with a design that we want, we need to add some properties to our class for managing the curves. Let’s add the following at the top of the class:
