VBFJellyView tutorial

It’s been a while since my last post!
This month has been crazy. I went to Madrid to teach iOS 3 days (UIViews, CoreGraphics and Layers) at ironhack. It was amazing, everyone was really nice and I enjoyed it a lot.
Also I have joined minube iOS team to help them develop a new version of their app. It is a very exciting project, and it is a pleasure to work with such talented guys!

Today I am here to talk about this pretty funny little thing.
I call it: ‘The Jelly View’

Pop Playground: playing with Facebook’s framework

Hi guys,

I have recorded a new screencast (in english… sorry if sometimes I struggle) talking about Pop (Facebook pop).

For the screencast I have prepared a project with 3 main tabs:

1) Basic explanation about pop with simple animations
2) 8 examples using different pop animations with many different animatable properties
3) 2 custon UIControls (unfinished). The only thing I have implemented are the animations.

These are the 2 controls you will find in the project:



Find the Github project here: PopPlayground

Finally, all the icons are from Captain Icon, you can grab them for free here

Snippet: screen snapshot

I have just found this piece of code, great for having in your snippet library. Quick and easy way of doing a screenshot.

After doing this, you can combine it with UIImage+ImageEffects for a nice blur effect.

Combo: skala preview + sketch 3

A few days ago I decided to buy Sketch 3. I am not a designer, but since I am about 16 years old I like to play around with Photoshop and Illustrator. I started because back then, making a realistic 3D render was very tricky (we didn’t have such a powerful computers), so it was good to tweak the renders afterwards with Photoshop.

Anyway, here I am having fun developing for iOS. And as well as most of you, I also have to mess around designing my interfaces. That is why I bought Sketch 3. I did try Sketch 2 and it was definitely the way to go (lucky me I didn’t buy it), so when Sketch 3 was released I just went for it.

However, this is not a post about Sketch 3, I don’t think I am the guy who should write about it. Designcode has a brilliant post about everything you need to know using Sketch 3.

The reason of this post is to talk about Skala preview and how well it works with Sketch (or any other). I know Sketch 3 comes with a mirror app, but to be honest… I have already spent quite a lot of money on the software itself, so if I can achieve the same thing for free… I will :)

New custom control: Dots Selector

Hi guys,

Seems like I am enjoying posting lately. That is good! I feel good to be back :D

Today I have been fighting for at least 3 hours to get this new custom control to work. As I mentioned before, I am working on a new app (the interface won’t be as crazy as WakeUp’s). I would like to move it forward as quick as possible and I am “wasting” (enjoying?) some of my holidays to do it.

Check the result on the following video (still need to tweak some values).



Yes, you are right. I have spent 3 hours moving some balls around the screen… But playing with UIKit Dynamics it’s just lots of fun!

Tutorial: create a menu using UIKit Dynamics

Before releasing the new version of WakeUp app, I posted a video about a new menu I was working on using mainly UIKit Dynamics.

I did promise a tutorial about it, and here it comes! This is an example of what we will do.


I have decided to modify slightly the way I write tutorials. I will write and explain the most important parts of the code, but I won’t go through every single line of code. I have uploaded a project in Github, where I have tried to comment the code as good as possible, use it as an extension of this tutorial.
