How can I add a degree sign to a string?

Question

I\'m writing in Objective-C. How can I add a degree sign to a string? I know its unicode: 00B0 and UTF8: C2 B0.

Answer 1

Just found this very helpful answer but it can even be abbreviated to the following (self explanatory):

NSString *temperature = @"65\u00B0";

Answer 2

NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:@"80\u00b0c"];
    [attributedString setAttributes:@{NSFontAttributeName : [UIFont fontWithName:@"Helvetica-light" size:40.0]
                                      , NSBaselineOffsetAttributeName : @22} range:NSMakeRange(2, 2)];
    //asign this as a 
examplelabel.attributedtext = attributedString;

Answer 3

Use the string literal: \u00B0. For Unicode characters, it will always be "\u" followed by the character code.

NSString *temperature = [NSString stringWithFormat:@"65%@", @"\u00B0"];

Answer 4

This is how you would do it using Swift:

var temperature = "65\u{00B0}" // degree symbol
