How to Animate an Svg Path in iOS

How do you animate an SVG path in IOS?

Try animating the 'stroke-dashoffset' (note that you need a matching 'stroke-dasharray' with it), see this example. The length of the path that needs to be computed to be able to use this successfully can be fetched via script like:

var pathlength = yourPathElm.getTotalLength()

View source on the example to see how it's done.

You have an extra semicolon at the end of the last paths for the values. You also have extra semicolons at the end of the d attributes

how do I animate a svg path?

You can give an id to one animate element and then do <id>.end to start the next when the first finishes. Here's an example

Animated SVG in UIView

PocketSVG will allow you to display and manipulate the lines of an SVG file.

PocketSVG *myBezier = [[PocketSVG alloc] initFromSVGFileNamed:@"BezierCurve1-iPad"];    
UIBezierPath *myPath = myBezier.bezier;

CAShapeLayer *myShapeLayer = [CAShapeLayer layer];
myShapeLayer.path = myPath.CGPath;

[self.view.layer addSublayer:myShapeLayer];
