Convert NSUInteger to string with ARC

I'm trying to cast a NSUInteger to a string so I can print a message. From searching, it seems like I need to use stringWithFormat, but I am getting an error that an implicit cast not allowed with ARC.

Here's the line in question:

NSString *text = [[NSString stringWithFormat: (@"%li",  NSUInteger)];

I've tried changing the format specifier to %lu with no help.

Thanks.

Solution

  • You probably have a variable of type NSUInteger, something like

    NSUInteger myNumber;

    Then you can convert it to a string like this:

    NSString *text = [NSString stringWithFormat:@"%li",  myNumber];

    A solution that I prefer now is this:

    NSString *text = [NSString stringWithFormat:@"%@",  @(myNumber)];

    This helps avoid compile warnings about incorrect number formatting codes (after a long time I still get confused in them).
