I have a UITextField with a placeholder. When the user wants to submit the form and he/she hasn’t typed anything in the textfield, I would like the placeholder’s text color become red. Here are my questions:
- Would that go against Apple’s User interface guidelines? I don’t want my app to be rejected because of such small detail.
- How I would do it?
I know I can override the method drawPlaceholderInRect: in a subclass of UITextField. But if I did this, the text would be always red and as I wrote before, I would like it to become red depending on a user defined action.
The only solution I can think of is to use a “default” text for my UITextField (the placeholder’s text), display it in light grey as long as the user hasn’t typed anything and display it in red when I need it. In other words, I would just mock the placeholder’s behavior. But of course, this is not very elegant.
Any ideas?
when user does not write any thing in textfield. then put this text as a textfield.text text and change font color.
