First commit of Temperature Converter

[brunoparrinello]

Hello,

could you please give me feedback on the temperature converter when you have a chance? I did not use the delegate, since I had questions on how to use it with multiple fields (even after watching the video). I'll try to look into it but would welcome some tips. :)

Thanks!

Check out this video for help with UITextField delegates: http://www.youtube.com/watch?v=c5SRKfGiHSg. For multiple UITextFields, note that delegate methods start with a textfield as the first parameter.

• The mockup was deliberately ambiguous about how to handle whether to convert from Celsius to Fahrenheit or vice versa. One good option was to track which textfield was the most recently edited.
• There are two ways to register for events for a UITextField: set the delegate or use the generic control events in Interface Builder. Generally speaking, it's more common to use the UITextField delegate methods.
• Optionally, you could have enforced input validation for the temperatures.
• The best keyboard to use is the decimal keyboard. The only downside is there is no negative key.

Hi there,

thanks for the video and tip! I replaced the listeners with the delegate, please let me know if this is correct.

• My versions handles the vice versa case. No need to enforce, which ever field is edited is considered the input, and the result will appear in the other field.
• I am already using the decimal pad. Any option to add the negative sign somewhere? Maybe enable a secondary keyboard with a toggle?

Thanks for any additional feedback you may have.

Looks good. As for the decimal pad, see the discussion here: https://canvas.instructure.com/courses/832436/discussion_topics/1929300
