Many successful apps have been based on custom photo filters, such as the highly popular Instagram app.
I’ve mentioned a really good image manipulation library in the past that allows for easy image manipulation providing cropping, and masking functionality along with several filters.
This new filter library is considerable different – specifically created so you can create customized image filters for great effects like that in this filtered image from the sample app:
The project is from Omid Hashemi, and can be found along with an example and usage instructions
A very nice and easy to use library for making image filters with a little bit of fiddling around you can make some great classic style photo filters.
If you need to detect gestures in your app, such as taps, pinches, pans, or rotations, it’s extremely easy with the built-in UIGestureRecognizer classes.
In this tutorial, we’ll show you how you can easily add gesture recognizers into your app, both within the Storyboard editor in iOS 5, and programatically.
We’ll create a simple app where you can move a monkey and a banana around by dragging, pinching, and rotating with the help of gesture recognizers.
We’ll also demonstrate some cool extras like:
- Adding deceleration for movement
- Setting gesture recognizers dependency
- Creating a custom UIGestureRecognizer so you can tickle the monkey! :]
I think the monkey just gave us the thumbs up gesture, so let’s get started! :]
At the end of this tutorial, you will be able to implement the Table View in the image below. This is a sample design for a social networking app. This screen will fit well in an app that shows Facebook or Twitter updates.
We will use some sample design resources to spruce up each cell and I will include a sample project with the design resources at the end of the post. You can download that and use them in your apps as you wish.
