Brad Larson和Bach都提供了非常有用的答案。第二个对我有用，但是需要预先显示图像。我想要更具动态性的东西，所以我将两种解决方案结合在一起：在UIImage上绘制所需的渐变使用UIImage设置颜色图案结果有效，在下面的屏幕截图中，您也可以看到一些希腊字符也很好地渲染。（我还在渐变顶部添加了笔触和阴影）iOS风格化UILabel，大棕狐狸这是我标签的自定义init方法，以及在UIImage上呈现渐变的方法（我从博客文章中获得的该功能的部分代码，现在找不到它可以引用它）：- (id)initWithFrame:(CGRect)frame text:(NSString *)aText { self = [super initWithFrame:frame]; if (self) { self.backgroundColor = [UIColor clearColor]; self.text = aText; self.textColor = [UIColor colorWithPatternImage:[self gradientImage]]; } return self;}- (UIImage *)gradientImage{ CGSize textSize = [self.text sizeWithFont:self.font]; CGFloat width = textSize.width; // max 1024 due to Core Graphics limitations CGFloat height = textSize.height; // max 1024 due to Core Graphics limitations // create a new bitmap image context UIGraphicsBeginImageContext(CGSizeMake(width, height)); // get context CGContextRef context = UIGraphicsGetCurrentContext(); // push context to make it current (need to do this manually because we are not drawing in a UIView) UIGraphicsPushContext(context); //draw gradient CGGradientRef glossGradient; CGColorSpaceRef rgbColorspace; size_t num_locations = 2; CGFloat locations[2] = { 0.0, 1.0 }; CGFloat components[8] = { 0.0, 1.0, 1.0, 1.0, // Start color 1.0, 1.0, 0.0, 1.0 }; // End color rgbColorspace = CGColorSpaceCreateDeviceRGB(); glossGradient = CGGradientCreateWithColorComponents(rgbColorspace, components, locations, num_locations); CGPoint topCenter = CGPointMake(0, 0); CGPoint bottomCenter = CGPointMake(0, textSize.height); CGContextDrawLinearGradient(context, glossGradient, topCenter, bottomCenter, 0); CGGradientRelease(glossGradient); CGColorSpaceRelease(rgbColorspace); // pop context UIGraphicsPopContext(); // get a UIImage from the image context UIImage *gradientImage = UIGraphicsGetImageFromCurrentImageContext(); // clean up drawing environment UIGraphicsEndImageContext(); return gradientImage;}我将尝试完成该UILabel子类并将其发布。
