What is the equivalent of NSLineBreakMode in iOS 7 attributed strings drawing methods?

There was a method

- (CGSize)drawInRect:(CGRect)rect withFont:(UIFont *)font lineBreakMode:(NSLineBreakMode)lineBreakMode alignment:(NSTextAlignment)alignment;

which I must replace now for iOS 7. I get as far as

  • UITableViewAutomaticDimension not working until scroll
  • How to lose margin/padding in UITextView?
  • UILabel position in a UITableViewCell fails on the first try
  • Forcing orientation change
  • Swift 3: How do I pinch to scale and rotate UIImageView?
  • mask text inside uitextview/uiwebview
  • NSDictionary *attributes = @{NSFontAttributeName: font};
    [self drawInRect:rect withAttributes:attributes];
    

    but how to specify the line break mode like word wrap? I searched documentation of Attributed string drawing symbols but no mention of line break mode. Is this automartically always word-wrap?

    You need to create a paragraph style.

    NSMutableParagraphStyle *style = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
    [style setLineBreakMode:NSLineBreakByWordWrapping];
    
    NSDictionary *attributes = @{NSFontAttributeName: font, NSParagraphStyleAttributeName: style};
    [self drawInRect:rect withAttributes:attributes];
    

    More information here:
    https://developer.apple.com/documentation/uikit/nsparagraphstyle?language=objc

    In swift:

    let style = NSMutableParagraphStyle()
    style.lineBreakMode = .ByWordWrapping
    
    let attributes: [String: AnyObject] = [
       NSFontAttributeName: font,
       NSParagraphStyleAttributeName: style
    ]
