Question

sizeWithAttributes

Answer 1

你可以试试这个......

 NSDictionary *attributes = @{NSFontAttributeName: [UIFont fontWithName:@"HelveticaNeue" size:14]};

[text sizeWithAttributes:attributes]

或

CGRect rect = [text boundingRectWithSize:CGSizeMake(width, MAXFLOAT) options:NSStringDrawingUsesLineFragmentOrigin attributes:attributes context:nil];
