The official Apples docs say: UITextFieldBorderStyleBezel - Displays a bezel-style border for the text field. This style is typically used for standard data-entry fields. UITextFieldBorderStyleRoundedRect - Displays a rounded-style border for the text field. This style is typically used for search buttons. So that means for all forms and stuff, they recommend Bezel. I wouldn't call myself an Apple guy or evangelist or anything (I'm actually a Windows guy), but in general, I find Macs like to use rounded fields and rounded buttons. There is a UISearchBar element, so I don't understand why they would want to use a UITextField for search buttons. So what are you guys using for UITextFields? As we are trying to appeal to the Apple crowd, look and feel.
