after inputAccessoryView tapped - iphone

I have tried the solutions at UITextView doesn't show InputAccessoryView on first click
I'm having a with a problem with a textView who has a inputAccessoryView
I want to call [textView resignFirstResponder] through its inputAccessoryView,so that i can close the keyboard
and there is only a UIButton on the inputAccessoryView,and the tapping the button will invoke an IBAction method call -(IBAction)closeKeyboard:(id)sender;
now the sender in the method is the button on the inputAccessoryView,
question is ,
how can i find out this textView whose inputAccessoryView has been tapped,
or just get a pointed which is pointed to this textView,so i can call
[textView resignFirstResponder]??

You need to find the current first responder. If you have outlets to all your text views, you can ask each one in turn
if ([textView1 isFirstResponder])
[textView resignFirstResponder];
Though this may give you problems depending on your button (see here, but I haven't experienced this), if so use the editing property of the text view.

How To Resign The UITextView With Done Button

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.
http://developer.apple.com/library/ios/#DOCUMENTATION/UIKit/Reference/UITextInputTraits_Protocol/Reference/UITextInputTraits.html#//apple_ref/occ/intf/UITextInputTraits
FINAL ANSWER
- (void)textViewDidEndEditing:(UITextView *)textView{
[textView resignFirstResponder];
}

show subview when UITextField touched

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];

UITableViewCell and resignFirstResponder

I have a UITableView containing in each cell a UITextField. When the user clicks on the UITextField, as expected, the keyboard will popup.
I have implemented in my delegate tableView: didSelectRowAtIndexPath: method to dismiss the keyboard with resignFirstResponder sent to the last UITextField used.
Everything works ok if the cell with the last UITextField used is displayed.
Now, if I scroll down to bottom of the tableview and press on a row, then the resignFirstResponder is sent to a hidden UITextField and will not hide the keyboard. It doesn't throw an error also.
How can I hide the keyboard in such cases?
Have a look at UITextFieldDelegate and put the
[textField resignFirstResponder];
method in one of the callback functions. I particulary prefer:
- (BOOL)textFieldShouldReturn:(UITextField *)textField;
Did you try calling endEditing:YES method of the UITextField?
-(IBAction)hidekey:(id) sender{
[textField resignFirstResponder];
}
if you using Interface builder then checked outlet of text field and in .m file use above function and define for that text field. It will work.
Please use this tutorial to Create a return Key for UIKeyboardTypeNumberPad ! This should save a lot of time for you.

Setting a UITextField into editing mode programmatically

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).

How to retract the Keyboard on touching the UITextView when keyboard is already up?

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.
