how to print infinity symbol in objective-c

Question

I need to set an NSString with infinity symbol '∞' and print it onto the screen. I don't know how to make it. Hope you guys could help.

Answer 1

你可以使用NSString *infinity = @"\∞";

Answer 2

您可以使用：

[NSString stringWithFormat:@"%C", 0x221E];

Answer 3

You can get the ASCII code and then create an NSString object.

Something like this:

int code = 236; //I believe this is the code you are looking for.
NSString *string = [NSString stringWithFormat:@"%c", code];

I hope this helps you.
