How to test if point falls inside bezier path

Last week I was working on the Spider Chart library. The purpose of this library is to plot data in 2 dimensions. One unit of data is plotted along the pie and other in radial direction. The problem I ran into was how to detect touch in one of the

Simulate View Controller Transitions - iOS/Objective-C

We all have dealt with push transition of UINavigationController as well as presentViewController and dismissViewController transitions of typical UIViewController. However, today we will learn how to emulate the transition from one viewController to another without moving to a new viewController. The technique is quite simple and I will only explain

Building simple image slider with Core Animation. You will soon find that it is supremely easy and customizable in terms of other options without having developer to deal with underlying intricacies. Since most of the code and functions are offered by Apple's core animation framework. We are going to use

In this we are going to learn how to animate the movement of shape along the bezier path. As we learned in the previous post, you can create a simple Sine wave shaped bezier path as follows, UIBezierPath* circularPath = [UIBezierPath bezierPath]; [circularPath moveToPoint:CGPointMake(50, 300)]; [circularPath addCurveToPoint:CGPointMake(300,

Animating bezier curve In the Last post we saw how to draw any arbitrary curves using two iOS classes viz. UIBezierPath and core animation class CAShapeLayer. First, let us draw a UIBezierPath of our desired style and then we will animate it. First create a UIBezierPath of desired shape. We

Drawing bezier curve using core animation Today we are going to learn how to draw arbitrary shapes using UIBezierPath and CAShapeLayer classes. Drawing shape with UIBezierPath is very simple. First you have to make an outline using UIBezierPath and then use this path to assign to path for CAShapeLayer object.
