Question

努力提供图表。与数据(推导斜线和斜线之间的线)合作,我感兴趣的是将这一数据绘制成图。

首先,请允许我向大家介绍我想要做的事情(见下文),解决办法是图表基具有梯度。

I presume the solution is to just take a block image of the gradient, and just cut the edges in code (somehow).

是否有将这样做的现有算法(目标-C)?

Answer 1

My solution was to map an image to a path with the use of a bezierPath. See the example code below

UIBezierPath* beizerPath2 = [UIBezierPath bezierPath];
[beizerPath2 moveToPoint:CGPointMake(0.0, 167)];       //Starting Point
[beizerPath2 addLineToPoint:CGPointMake(100, 40)];  
[beizerPath2 addLineToPoint:CGPointMake(200, 70)];    
[beizerPath2 addLineToPoint:CGPointMake(300, 30)];    
[beizerPath2 addLineToPoint:CGPointMake(320, 30)];    
[beizerPath2 addLineToPoint:CGPointMake(320, 167)];     //Finishing Point
[beizerPath2 closePath];                                //Close Path


NSLog(@"Masking Feedstock with Bezier");
CAShapeLayer *maskLayer = [CAShapeLayer layer];
maskLayer.path = [beizerPath2 CGPath];
graphFeedStock.layer.mask = maskLayer;

Answer 2

而你可以通过与比图数据合作,综合描绘你想要的任何东西。做很多事情的另一个容易的方法是,制作“情报调查”书,增加你想要的图像,然后从这个角度树立形象。
