ios - iOS 7.1 NSString drawInRect

Question

在我使用 iOS 7.1 构建项目之前，我的代码运行良好。之前，文本正确显示在 PDF 页面上。

[strSomeText drawInRect:rectForText withAttributes:[NSDictionary dictionaryWithObjectsAndKeys:font, NSFontAttributeName, mutParagraphStyle, NSParagraphStyleAttributeName, colorRed, NSForegroundColorAttributeName, nil]];

但是现在，格式化字典中的所有内容都被忽略了。PDF 文档显示默认字体和大小的黑色文本。

感谢您的回复。

Answer 1

你可以试试这个：

UIGraphicsPushContext(ctx);

[strSomeText drawInRect:rectForText withAttributes:[NSDictionary dictionaryWithObjectsAndKeys:font, NSFontAttributeName, mutParagraphStyle, NSParagraphStyleAttributeName, colorRed, NSForegroundColorAttributeName, nil]];

UIGraphicsPopContext();

Answer 2

我会尝试使用NSAttributedString并找出这是否有效。对于您的代码停止工作的原因，我没有充分的理由，但试试这个：

//    obviously these variables are examples, keep whatever variables you are using
UIFont *font = [UIFont fontWithName:@"whatever_font" size:16.0f];
NSParagraphStyle *paragraphStyle = [NSParagraphStyle defaultParagraphStyle];

NSDictionary *attributes = @{NSFontAttributeName : font, NSParagraphStyleAttributeName : paragraphStyle, NSForegroundColorAttributeName : [UIColor redColor]};

NSAttributedString *attributedString = [[NSAttributedString alloc] initWithString:exampleString attributes:attributes];

[attributedString drawInRect];
