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

Question

There was a method

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


        

Answer 1

In Swift 5:

let style = NSMutableParagraphStyle()
style.lineBreakMode = .byWordWrapping

let attributes: [NSAttributedString.Key: Any] = [
   .font: font,
   .paragraphStyle: style
]

Answer 2

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];
