I genuinely enjoy looking through on this site, it holds great blog posts. “One should die proudly when it is no longer possible to live proudly.” by Friedrich Wilhelm Nietzsche.

Fine blog post but I want to tell you that I think there is issue with your RSS feeds as they seem to not be working for me. May very well be just me but I thought overall I would state it.

I do believe all the ideas you have introduced on your post. They are really convincing and can certainly work. Still, the posts are very quick for starters. Could you please lengthen them a bit from next time? Thank you for the post.Riester Rente recently posted..1

In response to others who get garbage values after 10 or so digits are pressed, this is due to the fact that you are using float for currentNumber. Simply use long long instead of float. This will fix that problem.

Header file:
long long currentNumber;

Implementation:
calculatorScreen.text = [NSString stringWithFormat:@"%.2lld",currentNumber];

Thank you SO much for this clear, simple calculator. What I would like to do is have my custom calculator slide up when a user taps in the text box on the app. I’d love to know how to disable xcode’s standard keypad and slide this in instead. Can you make a suggestion? Thanks again for the great tutorial!
