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 

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];
