Dep*_*o B 1 dtcoretext swift ios8
我是DTCoreText,将HTML转换为属性文本.因为我想在前面设置字体,而不是之后,因为它会覆盖所有粗体,斜体等标签我想在构造函数中设置文档属性.这个构造函数要我给一个或多或少似乎是NSDictionary的AutoreleasingUnsafeMutablePointer？和前面的.有点.只有它不允许我以任何方式设置它.我试过.memory,尝试以任何可能的方式投射字典,它只是不接受任何数据.
let font = UIFont.systemFontOfSize(12)
let data = info.desc?.dataUsingEncoding(NSUTF8StringEncoding)
let attributes: NSMutableDictionary? = NSMutableDictionary()
attributes!.setObject(font, forKey: NSFontAttributeName)
var attributeRef: AutoreleasingUnsafeMutablePointer<NSDictionary?> = AutoreleasingUnsafeMutablePointer.null()
NSMutableAttributedString(HTMLData: data, documentAttributes: nil)
//attributeRef = *attributeDict
let attributedString = NSMutableAttributedString(HTMLData: data, documentAttributes:attributeRef)
let paragraphStyle: NSMutableParagraphStyle = NSMutableParagraphStyle()
paragraphStyle.lineBreakMode = NSLineBreakMode.ByWordWrapping;
let range = NSMakeRange(0, attributedString.length)
attributedString.addAttribute(NSParagraphStyleAttributeName, value: paragraphStyle, range: range)
lblMessage.attributedText = attributedString
此时你不应该使用DTCoreText; iOS现在有本机调用.只说var dict = NSDictionary?()和通过&dict.这是示例代码:
let s = "<html><body><h1>Howdy</h1><p>Hello</p></body></html>"
let d = s.dataUsingEncoding(NSUTF16StringEncoding, allowLossyConversion: false)
var dict = NSDictionary?()
let att = NSAttributedString(data: d!, options: [
NSDocumentTypeDocumentAttribute:NSHTMLTextDocumentType
], documentAttributes: &dict, error: nil)
println(att!)
println(dict!)
你会发现这非常有效.这是dict:
BottomMargin = 72;
Converted = "-1";
DocumentType = NSHTML;
LeftMargin = 90;
PaperMargin = "UIEdgeInsets: {72, 90, 72, 90}";
PaperSize = "NSSize: {612, 792}";
RightMargin = 90;
TopMargin = 72;
UTI = "public.html";
但是,我通常会通过,nil因为我真正关心的第二本字典中没有任何内容.
