SvgRenderer method asImage application chrash #42

Closed KlemenSpruk closed 3 years ago

KlemenSpruk commented 3 years ago

Hello!

When calling function:

/// Returns an image from svg string /// /// - Parameters: /// - svgString: A svg string to parse /// - size: Maximum size of the image returned /// - shouldScale: When se to true the size will be scaled by the screen scale. Defaults to "true" /// - Returns: An image generated from the string static func image(withSVGString svgString: String, maximumSize size: CGSize, scaleForRetina shouldScale: Bool = true) -> UIImage? { return SVGRenderer(string: svgString).asImage(with: size, andScale: shouldScale ? UIScreen.main.scale : 1.0) } an exception with msg. bellow occurs.

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[GHStyle renderIntoContext:withSVGContext:]: unrecognized selector sent to instance 0x283899a00' terminating with uncaught exception of type NSException

Is it possible to somehow use do ( try ... ) catch {...} in swift to catch this exception or is there any other way to ignore error if image cannot be created?

This is the first I’ve seen of this. What parameters are you using?

Same crash. GHStyle doesn't implement -(void) renderIntoContext:(CGContextRef)quartzContext withSVGContext:(id<SVGContext>)svgContext

Provided a fix. My apologies for taking so long.
