我一直在使用PaintCode在我的应用程序中绘制一些图形,一些绘制的元素具有使用“drawInRect”绘制的文本.无论我做什么尝试并设置颜色,文本总是显示为黑色.
这是创建文本的代码,我试图设置颜色：
//// Rounded Rectangle Drawing
UIBezierPath* roundedRectanglePath = [UIBezierPath bezierPathWithRoundedRect: CGRectMake(0,66,66) cornerRadius: 15];
[[NPSColor NPSPrimaryColor] setFill];
[roundedRectanglePath fill];
UIFont *helveticaFont = [UIFont fontWithName:@"AvenirNextCondensed-Bold" size:50];
NSMutableParagraphStyle *paragraphStyle = [[NSParagraphStyle defaultParagraphStyle] mutablecopy];
/// Set line break mode
paragraphStyle.lineBreakMode = NSLineBreakByWordWrapping;
/// Set text alignment
paragraphStyle.alignment = NSTextAlignmentCenter;
NSDictionary *attributes = @{NSFontAttributeName:helveticaFont,NSParagraphStyleAttributeName:paragraphStyle};
//// Text Drawing
CGRect textRect = CGRectMake(-4,-2.5,74,71.5);
[[NPSColor whiteColor] set];
[textContent drawInRect: CGRectInset(textRect,6) withAttributes:attributes];
}
“文本绘图”中的白色是不能正常工作的.谢谢你的帮助.
解决方法
您需要通过以下方式设置传入的“属性”字典中文本的颜色：
[textContent drawInRect: CGRectInset(textRect,6) withAttributes:attributes];
我的建议是：
NSDictionary *attributes = @{ NSFontAttributeName:helveticaFont,NSParagraphStyleAttributeName:paragraphStyle,NSForegroundColorAttributeName: [NPSColor whiteColor]}
