將 HTML 轉換為 NSAttributed 字串,反之亦然
-
Objective C 程式碼將 HTML 字串轉換為 NSAttributedString 和 Vice Versa
HTML 到 NSAttributedString 轉換程式碼: -
//HTML String
NSString *htmlString=[[NSString alloc]initWithFormat:@"<!DOCTYPE html><html><body><h1>My First Heading</h1><p>My first paragraph.</p></body></html>"];
//Converting HTML string with UTF-8 encoding to NSAttributedString
NSAttributedString *attributedString = [[NSAttributedString alloc]
initWithData: [htmlString dataUsingEncoding:NSUnicodeStringEncoding]
options: @{ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType }
documentAttributes: nil
error: nil ];
NSAttributedString 轉換為 HTML 轉換: -
//Dictionary to hold all the attributes of NSAttributed String
NSDictionary *documentAttributes = @{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType};
//Saving the NSAttributedString with all its attributes as a NSData Entity
NSData *htmlData = [attributedString dataFromRange:NSMakeRange(0, attributedString.length) documentAttributes:documentAttributes error:NULL];
//Convert the NSData into HTML String with UTF-8 Encoding
NSString *htmlString = [[NSString alloc] initWithData:htmlData encoding:NSUTF8StringEncoding];
