Decimal Pad is used which does not have allow negative entry. But via keyboard it's possible to test it.

Looks good!

• 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.
