Siri在iOS中聊天泡泡颜色

Question

我尝试在核心图形中创建Siri聊天气泡。我正处于可以绘制形状的阶段。我被困在这里的颜色。 Wanaa获得边框颜色和填充颜色代码。 这是我到目前为止所做的......

- (void)drawInContext:(CGContextRef)context
{

CGRect rect = gradientRectFrame;
CGFloat radius = 30;

CGFloat originBufferX = 0.0;
CGFloat originBufferY = 0.0;
CGFloat rightAngleTriangleWidth = 20.0;
CGFloat rightAngleTriangleHeight = 20.0;
CGFloat fullRectWidth = rect.size.width;
CGFloat fullRectHeight = rect.size.height;


CGPoint pointZero = CGPointMake(originBufferX, fullRectHeight);
CGPoint pointOne = CGPointMake(originBufferX + rightAngleTriangleWidth, fullRectHeight - rightAngleTriangleHeight);
CGPoint pointTwo = CGPointMake(originBufferX + rightAngleTriangleWidth, radius + originBufferY);
CGPoint pointThree = CGPointMake(originBufferX + fullRectWidth - radius, 0 + originBufferY);
CGPoint pointFour = CGPointMake(fullRectWidth, originBufferY + fullRectHeight - radius);    
CGContextSetRGBFillColor(context, 105/255, 105/255, 105/255, 0.5);
 CGContextSetLineWidth(context, 2.0);


CGContextMoveToPoint(context, pointZero.x, pointZero.y);

CGContextAddLineToPoint(context, pointOne.x, pointOne.y);

CGContextAddLineToPoint(context, pointTwo.x, pointTwo.y);

CGContextAddArc(context, rightAngleTriangleWidth + radius, originBufferY + radius, radius, M_PI, -M_PI_2, 0);

CGContextAddLineToPoint(context, pointThree.x, pointThree.y);

CGContextAddArc(context, fullRectWidth - radius, originBufferY + radius, radius, -M_PI_2, 0.0f, 0);

CGContextAddLineToPoint(context, pointFour.x, pointFour.y);

CGContextAddArc(context, fullRectWidth - radius, originBufferY + fullRectHeight - radius, radius, 0.0f, M_PI_2, 0);

CGContextAddLineToPoint(context, pointZero.x, pointZero.y);

CGContextFillPath(context);

CGContextSetRGBStrokeColor(context, 50/255, 50/255, 50/255, 0.5);

// CGContextSetRGBStrokeColor（context，1.0,0.0,0.0,1.0）;

CGContextStrokePath(context);

}

更新代码：我填充路径后，现在使用CGPath而不是CGContenxt来重绘我的路径。这是新的代码。虽然，我的笔触颜色还不是很接近..

- (void)drawInContext:(CGContextRef)context

{

CGRect rect = gradientRectFrame;
CGFloat radius = 20;

CGFloat originBufferX = 0.0;
CGFloat originBufferY = 0.0;
CGFloat rightAngleTriangleWidth = 20.0;
CGFloat rightAngleTriangleHeight = 20.0;
CGFloat fullRectWidth = rect.size.width;
CGFloat fullRectHeight = rect.size.height;


CGPoint pointZero = CGPointMake(originBufferX, fullRectHeight);
CGPoint pointOne = CGPointMake(originBufferX + rightAngleTriangleWidth, fullRectHeight - rightAngleTriangleHeight);
CGPoint pointTwo = CGPointMake(originBufferX + rightAngleTriangleWidth, radius + originBufferY);
CGPoint pointThree = CGPointMake(originBufferX + fullRectWidth - radius, 0 + originBufferY);
CGPoint pointFour = CGPointMake(fullRectWidth, originBufferY + fullRectHeight - radius);    

CGContextSetRGBStrokeColor(context, 0.8, 0.8, 0.8, 0.3);

CGMutablePathRef path = CGPathCreateMutable();
CGPathMoveToPoint(path, NULL, pointZero.x, pointZero.y);

CGPathAddLineToPoint(path, NULL, pointOne.x, pointOne.y);

CGPathAddLineToPoint(path, NULL, pointTwo.x, pointTwo.y);

CGPathAddArc(path, NULL, rightAngleTriangleWidth + radius, originBufferY + radius, radius, M_PI, -M_PI_2, 0);

CGPathAddLineToPoint(path, NULL, pointThree.x, pointThree.y);

CGPathAddArc(path, NULL, fullRectWidth - radius, originBufferY + radius, radius, -M_PI_2, 0.0f, 0);

CGPathAddLineToPoint(path, NULL, pointFour.x, pointFour.y);

CGPathAddArc(path, NULL, fullRectWidth - radius, originBufferY + fullRectHeight - radius, radius, 0.0f, M_PI_2, 0);

CGPathAddLineToPoint(path, NULL, pointZero.x, pointZero.y);

CGContextSaveGState(context);
CGContextAddPath(context, path);

CGContextSetLineWidth(context, 2.0f);
CGContextSetRGBFillColor(context, 1.0f, 1.0f, 1.0f, 0.1f);
CGContextFillPath(context);

CGContextAddPath(context, path);
CGContextStrokePath(context);

}

Answer 1

填充颜色大多为白色，不透明度约为10％。因此，原始背景（像图案的织物）闪耀并变得稍微更亮。边框颜色也是白色，但不透明度约为30％。

此外，边框右侧和底部有轻微的阴影。

对于颜色，您大概需要：

CGContextSaveGState(context);
CGContextSetShadow(context, CGSizeMake(-15f, -20f), 1.0f);
CGContextSetLineWidth(context, 2.0f);
CGContextSetRGBFillColor(context, 1.0f, 1.0f, 1.0f, 0.1f);
CGContextFillPath(context);
CGContextRestoreGState(context);

CGContextSetRGBStrokeColor(context, 1.0f, 1.0f, 1.0f, 0.3f);
CGContextStrokePath(context);
