How to disable and hide a UITextField
提问by Shawn
Hi I'm new in iPhone development, how do you disable a UITextField in iPhone development? If it matters, it is a View-Based Application, and the UITextField is named abc.

You use [abc setEnabled:NO]to disallow the user to edit it, or setHiddento completely hide it
你[abc setEnabled:NO]用来禁止用户编辑它，或者setHidden完全隐藏它

If you want to hide it completely:
如果你想完全隐藏它：
abc.hidden = YES;
If you just want to prevent user interaction:
如果您只想阻止用户交互：
abc.userInteractionEnabled = NO;
Since UITextField is a subclass of UIView (and UIControl), all the UIView (and UIControl) methods (such as those I used above) are available.
由于 UITextField 是 UIView（和 UIControl）的子类，所有 UIView（和 UIControl）方法（例如我上面使用的那些）都可用。

[textField setHidden:YES];
[textField setHidden:NO];
If it is hidden, the user can't interact with it or see it.
如果它是隐藏的，用户将无法与它交互或看到它。

You can do this a few ways.
您可以通过几种方式做到这一点。
abc.alpha = 0; //text field is there, just transparent, so it can't be seen.
abc.hidden = TRUE; // textfield is hidden, not on View at all.
abc.userInteractionEnabled = FALSE; // user can see the text field and any text
// that has already been set but cannot edit
