Capture a Signature on iOS

Capture a Signature on iOS | PandaLit | Scoop.it

"The Square Engineering Blog has a great article on Smoother Signatures for Android, but I didn't find anything specifically about iOS. So, what is the best way to capture a users signature on an iOS device?

 

Although I didn't find any articles on signature capture, there are good implementations on the App Store. My target user experience was the iPad application Paper by 53, a drawing application with beautiful and responsive brushes.

 

All code is available in the Github repository: SignatureDemo."

Death to printf() - JATemplate, an helper to format NSString

Actually, there’s a conceptually simple win: don’t let your format strings determine the byte-level interpretation of data. Especially without bounds.

 

I mean, duh. Who’d do something so obviously stupid? Well, unfortunately, the C standard library does, and its example has been followed all too many times. I contend that printf()-style formatting is broken and its use should be considered a bug.

 

In order for this idea to have any chance of taking off, there needs to be a replacement which is at least as convenient as printf()-style formatting. That gives us three goals: safety, convenience, and easy internationalization. To get the ball rolling, I have prototyped such a thing for Objective-C, called JATemplate.

iOS 5 Face Detection with Core Image

iOS 5 Face Detection with Core Image | PandaLit | Scoop.it

One of the great new features of iOS 5 is the addition of the Core Image (CI) framework.

This framework has been available for a few years on the Mac, but now its advanced image processing and filtering capabilities are available on the iOS platform as well.

One particularly cool new feature available in Core Image, on both iOS 5 and Lion, is its ability to detect faces in an image.

iOS Tutorial: Image Cache and Loading Thumbnails using MKNetworkKit

iOS Tutorial: Image Cache and Loading Thumbnails using MKNetworkKit | PandaLit | Scoop.it

MKNetworkEngine makes it a breeze to add this feature into your app. What not? With MKNetworkKit, you will even know if the response image is from cache or loaded for the first time. Using this information, you can “fade in” your thumbnails when you load the images for the first time

How to use Custom UIButton Graphics for iPhone Applications

How to use Custom UIButton Graphics for iPhone Applications | PandaLit | Scoop.it

In this tutorial I’d like to show you a simple way to implement your own custom button graphics. I’ll be using the latest Xcode 4.2 release and building an application in iOS5. You do not need to understand Objective-C but it certainly doesn’t hurt the process. When building iPhone apps you’ll eventually have to deal with code so Objective-C should be something to embrace!

How To Create a Rotating Wheel Control with UIKit | Ray Wenderlich

How To Create a Rotating Wheel Control with UIKit | Ray Wenderlich | PandaLit | Scoop.it

This is a post by iOS Tutorial Team member Cesare Rocchi, a UX designer and developer specializing in web and mobile applications.

 

There may be times you’ve downloaded a cool application with a new kind of user interface component, and you’ve wondered: how was it built?

One great example of this is the rotary wheel, used by ConvertBot and other applications as a way for users to select options from a menu.

This component is intuitive to use because it resembles many similar controls we use in real life to make choices.
