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.

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'm pretty new to iPhone development, so please excuse my ignorance. I've googled this a bit and so far come up with nothing useful. Here is what I would like to do:
I would like a subview to popup(with the rest of the screen showing in the background) when a UITextField is touched. The popup is a calculator UIView that I created in the IB. It seems it is better to have a popup show than a customized keyboard, due to Apple's developer guidelines.
Here is my question. How do I capture the touch on the UITextField and how do I show the subview?
I have tried things like below to show the subview, with no luck:
CustomCalculator *customCalc = [[CustomCalculator alloc] initWithNibName:#"CustomCalculator" bundle:nil];
UIViewController *calcController = [self.customCalc.view];
[self.view addSubview:calcController.view];
Use the delegate method:
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
//Add your subview here
return NO; //this will stop the keyboard from poping up
}
This way when someone taps the textfield, your view will popup instead of the keyboard.
Now once the user is interacting with your view, you will have to manipulate the string in the textfield.text property directly as a reaction to the User tapping buttons in your view.
Implement the UITextFieldDelegate and the method for it is
-(void) textFieldDidBeginEditing:(UITextField *)textField
The above method is fired when you touch the UITextField. You may then position the UIPopoverController (I'm guessing that is what you're using to show the view in a popup) and as soon as you're done there pass the values back to the UITextField. Hence the popover's/viewcontroller presented's delegate should be your textfield object.
EDIT: After seeing the other answer below it struck me that I forgot to tell you how to stop the keyboard from showing. Just make this the first line in the method I've mentioned above:
[textField 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).
Is there a way to make a custom keyboard to pop up when a user presses on a UITextField. I have a view with a custom keypad on it and I want that to come up when the user presses on the UITextField instead of the default apple keyboard.
Since iOS 3.2 there's a property for exactly that, called inputView.
just go like this: [myTextField setInputView:myInputView] - where myInputView is obviously your custom input view. Then the system will pop up your view instead of the predefined keyboards.
You may set delegate in your UITextField and return NO in textFieldShouldBeginEditing:.
not sure I understand the question? the keyboard type can be assigned to the UITextField so If you want a different one then specify it when initializing the object
UITextField * textFld = [[UITextField alloc] init];
textFld.keyboardType = UIKeyboardTypeNumbersAndPunctuation;

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.
