Syntax Highlighting
April 09, 2011
I now have syntax highlighting on my blog. Let’s see how it works with objc:
- (void)drawRect:(CGRect)rect {
// Drawing code
CGContextRef ctx = UIGraphicsGetCurrentContext();
CGContextClearRect(ctx, rect);
//[[UIColor clearColor] set];
//CGContextFillRect(ctx, rect);
if( makeCache ){
[self updateBitmapContextIfNeeded];
CGImageRelease(cachedImage);
cachedImage = CGBitmapContextCreateImage(backingStore);
makeCache = NO;
}
CGContextDrawImage(ctx, CGRectMake(0, 0, CGBitmapContextGetWidth(backingStore), CGBitmapContextGetHeight(backingStore)), cachedImage);
CGMutablePathRef path = CGPathCreateMutable();
CGContextSetLineWidth(ctx, 2.5);
for(NSMutableDictionary* stroke in intermediateStrokes){
NSMutableArray* points = [stroke objectForKey:@"points"];
[self drawPointInCurrentContext:points path:path];
}
[[UIColor blackColor] set];
CGContextAddPath(ctx, path);
CGContextStrokePath(ctx);
CGPathRelease(path);
//[super drawRect:rect];
/*[[UIColor whiteColor] setStroke];
UIBezierPath* path = [UIBezierPath path];
[path moveToPoint:CGPointMake(0, 0 )];
[path addLineToPoint:CGPointMake(320, 480)];
[path addLineToPoint:CGPointMake(0, 480)];
*/
}
Looks like it works! :D
