如何在drawAtPoint中更改NSString的颜色 [英] How to change color of NSString in drawAtPoint

问题描述

这里有这段代码，它绘制了一个带有一个字符字符串的块:

I have this chunk of code here that draws a block with a one-character string on it:

CGContextDrawImage(context, CGRectMake([blok getLocation].x * xunit, [blok getLocation].y * yunit, 40, 40), [blok getImage].CGImage);
[[blok getSymbol] drawAtPoint:CGPointMake([blok getLocation].x * xunit+15, [blok getLocation].y * yunit) withFont:[UIFont fontWithName:@"Helvetica" size:24]];

它工作正常，但是我一直在进行一些布局更改，现在我需要它，以便绘制的字符串为白色.使用设置填充颜色和笔触颜色的方法没有做任何事情.还有其他方法吗?

It's working fine, but I've been doing some layout changes, and now I need it so that the string drawn will be white. Using the methods for setting the fill color and the stroke color haven't done anything. Is there some other way to do this?

推荐答案

您是否尝试过:

CGContextSetFillColorWithColor(UIGraphicsGetCurrentContext(), textColor);

例如:

CGContextDrawImage(context, CGRectMake([blok getLocation].x * xunit, [blok getLocation].y * yunit, 40, 40), [blok getImage].CGImage);
CGContextSetFillColorWithColor(UIGraphicsGetCurrentContext(), textColor);
[[blok getSymbol] drawAtPoint:CGPointMake([blok getLocation].x * xunit+15, [blok getLocation].y * yunit) withFont:[UIFont fontWithName:@"Helvetica" size:24]];
