I have a UIButton - a submit button - that I set the enabled and disabled states and titles for. I use the submit button title to show status like #"Sending..." while my program is making an api call by disabling the button.
It works fine until the edge case where someone enters a comment on a UITextField, but instead of dismissing the keyboard/finishing editing just hits the SUbmit button (so the keyboard is still up).
In this case, disabling the button doesn't change the title and background to the disabled state.
Is this an issue with firstResponder? I'm trying to explicity tell the comment field to resignFirstResponder before setting the button.enabled = NO, but it still doesn't update the button.
Are you implementing this UITextFieldDelegate method:
- (void)textFieldShouldEndEditing:(UITextField *)textField {
[textField resignFirstResponder];
button.enabled = NO;
}
and then resigning the text field's first responder and disabling the button?
Sometimes textFieldSHouldEndEditing doesn't get called since the field may not lose focus, so I do try to explicity tell the text field to resign before disabling the button. Doesn't seem to work...

I have a UITextField that is first responder. I want to show keyboard when entering the view but I want to do that the user will not be able to edit it and the cursor will be hidden all time as well.
When you click on a keyboard letter, it will be written in the UITextField, but the user will not be able to edit nothing there, even not to copy.
Thanks!
Ok, per my comment, my solution is to have a surrogate UITextField that has its hidden property set to YES. What I do is add that hidden text field to the view, and call becomeFirstResponder on it. The user has no idea this text field exists. In the delegate callback from the text field, I take the text the user typed in and add it to a UITextView (though you could add the text to whatever you wanted, like a UITextField like in your question). I turn off userInteractionEnabled for the visible text view. This creates the effect you desire.
I created a sample project that I uploaded to Github. (If you aren't familiar with it, just click the zip button to download it, unzip it, and open the .xcodeproj file). https://github.com/MaxGabriel/HiddenTextField
I had a UISearchBar property in my viewController. And I did it like this:
- (void)viewWillAppear:(BOOL)animated
{
[self.searchBar becomeFirstResponder];
}
This should work the same for a UITextField.
As for disabling editing, use:
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField{
return NO;
}
You should have set your viewController to be the delegate of UITextField.
Edited answer: Try this:
1. [txtField becomeFirstResponder];
2. txtField.enabled = NO;
3. when some press on keyboard, then txtField.enabled = YES;

i was wondering if any of you knew how to get access to that done button that appears above the keyboard when editing.
I have seen it before, above the keyboard there is a transparent black area and on the right there is a blue "Done" Button.
I could do this by hand with my own animations and buttons above the keyboard in my app to resign the UITextView, but i would prefer to use Apple GUI elements that people know.
So does anybody have any information about where this "Done" button comes from?
You don't really "get access" to that button, but through the UITextViewDelegate protocol, you essentially can:
http://developer.apple.com/library/ios/#DOCUMENTATION/UIKit/Reference/UITextViewDelegate_Protocol/Reference/UITextViewDelegate.html
Implement the
- (void)textViewDidEndEditing:(UITextView *)textView
routine, and assign the UIViewController holding the textview to the textview' delegate.
Inside of that routine, you can do what you wish! You will need to call the
resignFirstResponder
method.
http://developer.apple.com/library/ios/#DOCUMENTATION/UIKit/Reference/UIResponder_Class/Reference/Reference.html#//apple_ref/occ/instm/UIResponder/resignFirstResponder
You will have to implement the style of keyboard that implements that blue done button.

FINAL ANSWER
- (void)textViewDidEndEditing:(UITextView *)textView{
[textView resignFirstResponder];
}
I have a UITextField that I want to set into editing mode (keyboard on screen and cursor in text field box) programatically. I know that the user will be in editing mode when this view appears onscreen, so I want to save the user from having to tap the text field.
The "editing" property of a UITextField is read only - so that doesn't work. Is there a way to set the UITextField into editing mode, with a keyboard onscreen, programmatically?
Call becomeFirstResponder on the UITextField.
Related question:
How do I show the keyboard by default in UITextView?
You have to call [textField becomeFirstResponder];
Indeed call [textField becomeFirstResponder] in Obj-C or textField.becomeFirstResponder() in Swift.
However, make sure you call this in the viewDidAppear and not in the viewDidLoad to prevent strange behaviour (see: When set UITextField as FirstResponder programmatically, cause some weird actions on text editing).
I am writing an application that has a UITextView which allows editing. When a user first touches UITextView, a keyboard shows up and I want to retract that keyboard when user again touches the UITextView e.g. I have entered some data in a textview and with keyboard still showing on the screen I tap on the UITextView which should cause the keyboard to retract.
Is there any way to achive this?
(I'm aware of providing a done button and doing this but I want to achive this by tapping on UITextView itself)
As an aside, I would urge you not to use toggle state elements on the iPhone. It's to easy to double tap in real world use. That is why the Apple apps all use the either the "return" key on the keyboard or the done button.
In the interface you contemplate, the users will find themselves closing and then accidentally reopening the keyboard about 10% of the time or more. It will make your app feel cumbersome and flaky.
You should call resignFirstResponder for the UITextView. Let's say you have an IBOutlet for the text view:
#property (nonatomic, retain) IBOutlet UITextView *comment;
Then [comment resignFirstResponder]; can be called from a touchesBegan or the like.
See e.g. How to Dismiss the Keyboard when using a UITextView.
What you are looking for is a large transparent uibutton "overlapButton" which always stays on top of the uitextview.
When the textview appears, you set the button hidden so you can tap on the textview freely.
[overlapButton setHidden:YES];
When tapping the textview, the keyboard will come up and the following method inside your textview delegate will get called:
-(BOOL)textViewShouldBeginEditing:(UITextView *)textView{
[overlapButton setHidden:NO];
}
Here, you need to set visible the "overlapButton" so that while the keyboard is up, you can touch the button which now overlaps the textview. On the button action, you can hide the keyboard:
-(IBAction) overlapButtonTapped{
[myTextView resignFirstResponder];
}
After resigning the first responder, the following method will get called:
-(BOOL)textViewShouldEndEditing:(UITextView *)textView{
[overlapButton setHidden:YES];
}
After setting the hidden property accordingly for the button (like above), you have a "clear" textview again which you can tap again to show the keyboard.. etc .. etc ..
Cheers.
I agree with you TechZen. I've seen this happen! I would not advise this also! It also makes editing very hard if not impossible for edit/copy/paste gestures. On the other hand, if the man still wants this badly.. :P the code provided by me in my other post works a treat! Cheers.
On my iPhone app I'm using a UISearchBar (without a Search Display Controller). I have my own 'Search' button as a UIButton and therefore on the keyboard that pops up when editing begins on a UISearchBar I would like to constantly hide the 'Search' button on it as it is unusable. How could I go about doing this without the Search Display Controller?
Or instead - is it possible to continue using my UISearchBar and UIButton 'Search', and also get the keyboard 'Search' button to work as well? I have tried -
(void)searchBarSearchButtonClicked:(UISearchBar
*)searchBar
However my UISearchBar is called 'searchbar' and therefore isn't responding to that (changing the searchBar to searchbar doesn't work either). When I instead use a UISearchBar with a Search Display Controller is works perfectly - however, I don't want the new table view that it opens on editing - or is there a way to prevent this too?
Thanks in advance!

--EDIT: SOLVED. I just used a textfield instead upon the searchbar so it looks similar.
SOLVED. I just used a textfield instead upon the searchbar so it looks similar.
If you want to change UISearchBar's textfield, you may use the following code:
UITextField *textField = [searchBar.subviews objectAtIndex:1];
textField.returnKeyType = UIKeyboardTypeDefault;
textField.leftView = nil;
textField.delegate = self;
But if you want to have an edit bar, a customized one is more appropriate.
For example, create a toolbar and add a UITextField, a Flexible Space and a UIBarButtonItem with text "send" on it. Then it will look like the edit bar in SMS app.
