👍 Congratulation on finishing the Tip Calculator. Your app looks good.

Some small comments:

• Good usage of the NSUserDefault. This is one of the methods to pass data between view controllers.
• Nice usage of NSNotificationCenter.
• Well done with using the locale currency.
• Good job with implementing the remembering the amount feature. But it'd better if use save the old amount with 10mins.
• For now, users cannot input the decimal number in the text field.
• You shouldn't let the user enter invalid number, should you? I can enter bunch of leading zeros. I can also paste some text in the text field:
• The total amount is truncated when the bill amount is too big.

Thanks Chau for your comments! I missed the data validation and the truncated display, my bad :(. For remembering old amount, I have implemented the 10 minutes constraint with this code: if timeInterval < 600{....} // namely if the elapsed time is < 10 minutes, load the old amount. I tested this feature again, seemed working for me. Can you put more description for the issue you have had there? Thank you very much for your support!
