DrowningGraphicer

CoreGraphics wrapper library.

• Core concept is simple
• You don't have to pass CGContextRef as argument.
• Automatically-managed CGContextRestoreGState / CGContextSaveGState.
  • Allow you to forget that CGContext*GState.

Installation

pod 'DrowningGraphicer', :git => 'https://github.com/azu/DrowningGraphicer.git'

Usage

- (void)drawContext:(CGContextRef) context size:(CGSize) size {
    DrowningGraphicer *drowning = [DrowningGraphicer drowningWithContextRef:context];
    // *1 Automatically call `CGContextSaveGState(ctx)`
    [drowning lineContext:^(DrowningGraphicsLineContext *lineContext) {
        NSUInteger count = 30;
        for (NSUInteger i = 0; i < count; i++) {
            CGFloat yPosition = (size.height / count) * i;
            [lineContext drawLine:CGPointMake(0, yPosition)
                         endPoint:CGPointMake(CGRectGetWidth(self.frame), yPosition)
                         lineColor:[UIColor blackColor]];
        }
    }];
    // *1 Automatically, call `CGContextRestoreGState(ctx);`
    // *2 Automatically call `CGContextSaveGState(ctx)`
    [drowning arcContext:^(DrowningGraphicsArcContext *arcContext) {
        [arcContext drawFilledCircle:CGPointMake(size.width / 2,
            size.height / 2) radius:5 color:[UIColor blueColor]];
    }];
    // *2 Automatically, call `CGContextRestoreGState(ctx);`
}
