Parsing HTML into NSAttributedText - how to set font?
html, ios, nsattributedstring
Solution
Figured it out. Bit of a bear, and maybe not the best answer.
This code will go through all the font changes. I know that it is using "Times New Roman" and "Times New Roman BoldMT" for the fonts. But regardless, this will find the bold fonts and let me reset them. I can also reset the size while I'm at it.
I honestly hope/think there is a way to set this up at parse time, but I can't find it if there is.
- (void)changeFont:(NSMutableAttributedString*)string
{
NSRange range = (NSRange){0,[string length]};
[string enumerateAttribute:NSFontAttributeName inRange:range options:NSAttributedStringEnumerationLongestEffectiveRangeNotRequired usingBlock:^(id value, NSRange range, BOOL *stop) {
UIFont* currentFont = value;
UIFont *replacementFont = nil;
if ([currentFont.fontName rangeOfString:@"bold" options:NSCaseInsensitiveSearch].location != NSNotFound) {
replacementFont = [UIFont fontWithName:@"HelveticaNeue-CondensedBold" size:25.0f];
} else {
replacementFont = [UIFont fontWithName:@"HelveticaNeue-Thin" size:25.0f];
}
[string addAttribute:NSFontAttributeName value:replacementFont range:range];
}];
}
Problem
I am trying to get a snippet of text that is formatted in html to display nicely on an iPhone in a UITableViewCell. So far I have this: ``` NSError* error; NSString* source = @"<strong>Nice</strong> try, Phil"; NSMutableAttributedString* str = [[NSMutableAttributedString alloc] initWithData:[source dataUsingEncoding:NSUTF8StringEncoding] options:@{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType, NSCharacterEncodingDocumentAttribute: [NSNumber numberWithInt:NSUTF8StringEncoding]} documentAttributes:nil error:&error]; ``` This kind of works. I get some text that has 'Nice' in bold! But... it also sets the font to be Times Roman! This is not the font face I want. I am thinking I need to set something in the documentAttributes, but, I can't find any examples anywhere.
