Few! That's a lesson in object-oriented programing right there.

Hide Caret

To hide the caret, nil out the text field's selected text range.

<pre><code>textField.selectedTextRange = nil; // hides caret
</code></pre>

Unhide Caret

Here are two ways to unhide the caret.

<ol>
<li>Set the text field's selected text range to the end of the document.

<pre><code>UITextPosition *end = textField.endOfDocument;
textField.selectedTextRange = [textField textRangeFromPosition:end
 toPosition:end];
</code></pre></li>
<li>To keep the caret in the same spot, first, store the text field's selected text range to an instance variable.

<pre><code>_textFieldSelectedTextRange = textField.selectedTextRange;
textField.selectedTextRange = nil; // hides caret
</code></pre>

Then, when you want to unhide the caret, simply set the text field's selected text range back to what it was originally:

<pre><code>textField.selectedTextRange = _textFieldSelectedTextRange;
_textFieldLastSelectedTextRange = nil;
</code></pre></li>
</ol>

I found another solution: subclass <code>UIButton</code> and override these methods

<pre><code>- (UIView *)inputView {
 return inputView_;
}

- (void)setInputView:(UIView *)anInputView {
 if (inputView_ != anInputView) {
 [inputView_ release];
 inputView_ = [anInputView retain];
 }
}

- (BOOL)canBecomeFirstResponder {
 return YES;
}
</code></pre>

Now the button, as a <code>UIResponder</code>, have a similar behavior than <code>UITextField</code> and an implementation pretty straightforward.

Answer provided by the OP, copied from the question body to help clean up the ever growing tail of unanswered questions.

I think I have the correct solution but If it can be improved will be welcome :) Well, I made a subclass of UITextField and overriden the method that returns the CGRect for the bounds

<pre><code>-(CGRect)textRectForBounds:(CGRect)bounds {
 return CGRectZero;
}
</code></pre>

The problem? The text doesn't show because the rect is zero. But I added an UILabel as a subview of the control and overridden the setText method so, as we enter a text as usual, the text field text is nil and is the label which shows the text

<pre><code>- (void)setText:(NSString *)aText {
 [super setText:nil];

 if (aText == nil) {
 textLabel_.text = nil;
 }

 if (![aText isEqualToString:@""]) {
 textLabel_.text = aText;
 }
}
</code></pre>

With this the thing works as expected. Have you know any way to improve it?

You can add a <code>BOOL cursorless</code> property to <code>UITextField</code> in a category via associated objects.

<pre><code>@interface UITextField (Cursorless)

@property (nonatomic, assign) BOOL cursorless;

@end
</code></pre>

Then use method swizzling to swizzle <code>caretRectForPosition:</code> with a method that toggles between <code>CGRectZero</code> and its default value using <code>cursorless</code>.

This leads to a simple interface via a drop-in category. This is demonstrated in the following files.

Simply drop them in and get the benefit of this simple interface

I am using a <code>UITextField</code> with a <code>UIPickerView</code> for its <code>inputView</code>, so that when the user taps the text field, a picker is summoned for them to select an option from.

Nearly everything works, but I have one problem: the cursor still flashes in the text field when it is active, which is ugly and inappropriate, since the user is not expected to type into the field and is not presented with a keyboard. I know I could hackily solve this by setting <code>editing</code> to <code>NO</code> on the text field and tracking touches on it, or by replacing it with a custom-styled button, and summoning the picker via code. However, I want to use the <code>UITextFieldDelegate</code> methods for all the event handling on the text field and hacks such as replacing the text field with a button do not permit this approach.

How can I simply hide the cursor on the <code>UITextField</code> instead?
