I made a research and all posts here are very blury regarding this issue.
I would like to use a UIPicker when pressing on a UITextField.
I would realy appriciate a step by step guide.
I tryd all posts here but every post gives me only a portion of what I need and I can't seem to connect it all together.
This is the last part of my application and i'm going crazy to finish it..
Thank you in advanced!

There is an inputAccessoryView property that contains a view that will appear instead of a keyboard on the bottom of the screen. Create a UIPicker, adjust its frame, provide values and assign it to the inputAccessoryView property.
UIPicker will appear when user taps on your UITextField.
If you don't need editing, you may use a UILabel instead of the UITextField. Solution is the same. I have a ready-made class if you need.
Here's a way:
http://www.youtube.com/watch?v=t_F1ex5opgA&t=14m10s
-(BOOL)textfieldShouldBeginEditing:(UITextField *)textField
where textField is the name of your text field.
Call your UIPickerView and return NO so that your picker is loaded rather than the keyboard.
The idea is to call an action that opens the UIPicker when the user taps the UITextField. Because the UITextField does not responde to the usual touchUpInside events that UIButtons respond to, I would just overlay a transparent UIButton on top of the UITextField and just in case, make the text field's userInteractionEnabled property NO. Hook the UIButton to responde to touchUpInside and call a method that opens the UIPicker. Another option would be an immediate response to the text field's touch by implementing "textFieldShouldBeginEditing" and immediately resigning the text field.
The next step would be to present the UIPicker - if we are talking about iPad, this would best be done by using a UIPopoverController. On iPhone, maybe consider bringing it up modally. When you create the view controller that holds this UIPicker, be sure to add a delegate property to it so that whatever value that was selected on the picker can be transfered back to the main view controller and on to the UITextField.
Hope this helps with getting you started.

I have a UIPickerView that I created programmatically. It shows up when someone presses the UITextField on the screen. The only problem is that if someone presses the UITextField after the UIPickerView has already been populated, more and more PickerViews start layering on top of the previous one.
What is the proper way to suppress populating a UIPickerView if one is already on screen?
There are ofc. multiple ways of doing this, but the most simple would be to just keep a reference to UIPickerView. In other words just store it away in a class variable and check if it's not nil.
You could also set the tag property on the UIPickerView and by querying it's super view check if it is already there. More info on tags: http://developer.apple.com/library/ios/documentation/uikit/reference/uiview_class/uiview/uiview.html#//apple_ref/occ/instp/UIView/tag
Does that make sense?
You could disable your UITextField once the UIPicker appears, and re-enable it once you have dismissed the picker.
I need to show UIKeyboard with done button on top right corner ..please look into attached image..any help would be appreciated.
This might help you. please check it out BSKeyboardControls
Create a UIToolbar keep two bar buttons in that. Initially Hide that toolbar.
Show the toolbar on the textfield didBeginEditing delegate of textfield
and hide the toolbar in didEndEditing delegate of textfield
EDIT: As prashant said BSKeyboard offers what i said. See the look and feel of it here http://www.cocoacontrols.com/platforms/ios/controls/bskeyboardcontrols
You should set inputAccessoryView propery of UITextField or UITextView to your custom view with all required buttons
#property(readwrite, retain) UIView *inputAccessoryView
Description
The custom accessory view to display when the text field becomes the
first responder The default value of this property is nil. Assigning a
view to this property causes that view to be displayed above the
standard system keyboard (or above the custom input view if one is
provided) when the text field becomes the first responder. For
example, you could use this property to attach a custom toolbar to the
keyboard.
I have a simple UITextField called month where I get users to simply enter the month they want via the keyboard that comes up. I would now like it for them to be able to use a UIPickerDate (or UIPicker) to make this selection instead. So when they press on the text field, a mini UIPicker appears and they make there selection, press anywhere on the screen and the picker disappears.
Does anyone know how to do this or has any suggestions? I am pretty new to programming and have looked at other answers but everyone seems to be referring to this being done in a table.
Thanks in advance!
You can set the inputView property on the UITextField to be an instance of UIDatePicker. When the instance of UITextField becomes the first responder, the picker view will be displayed with the standard keyboard animation.
// Assume that self.monthTextField and self.datePicker
// are properties of the view controller class
self.monthTextField.inputView = self.datePicker;
As for dismissing, that depends on the context. If there are more text fields to populate, consider adding a UIToolbar as the inputAccessoryView of self.monthTextField. Then you can add something like a UIBarButtonItem to make the next text field the first responder, similar to how the standard keyboard provides a Next button.
I have a UITextfield of type NumberPad in a UITableViewCell. How can I make it resign first responder (i.e. dismiss the keyboard)?
Thanks
You have to add a UIButton somewhere in your interface. I often do it on the navigation bar and then resign first responder when it is pressed.
There are all sorts of kludges to superimpose fake done buttons over the numberpad, but they are asking for trouble IMHO. It would be nice if Apple addressed this in future though as lots of people have the same issue.
Good discussion and other solutions here;
How to show "Done" button on iPhone number pad
Implement UITextFieldDelegate and set your UITextField delegate to it. In the -(BOOL)textFieldShouldReturn:(UITextField *)textField delegate method you set the resignFirstResponder call.
You can also set up an action to a button on the pad. You can do this by trying to add a done button to the pad. I know that in the most recent sdk this is somewhat impossible.
For those cases you have two options:
1.Add a done button somewhere on the view. If you are using a navigation controller you can add it to the navigation bar and simply set up the action for that button and in the action you resignFirstResponder for the UITextField.
2.Add your keyboard to a UIActionSheet and add the done button right on top of the keyboard.
Is there a way to do a general resignFirstResponder to hide the keyboard regardless of what textfield/view/etc calls it?
Reason is I have a lot of textfields on my view and don't want to have to resignFirstResponder for all textfields to hide the keyboard. Just want a general
[self resignFirstResponder].
Any ideas?
Thanks in advance
I know that this has already been marked as answered, but for those that run into this like I did you can just use the following method on the view that contains the textfields.
- (BOOL)endEditing:(BOOL)force
This method looks at the current view and its subview hierarchy for the text field that is currently the first responder. If it finds one, it asks that text field to resign as first responder. If the force parameter is set to YES, the text field is never even asked; it is forced to resign. UIView Documentation
[self.view endEditing:YES];
it will hide keyboard when we click on view.
You can dismiss the keyboard without any reference to UITextfield / UITextView with help of below code:
[[[UIApplication sharedApplication] keyWindow] endEditing:YES];
this will dismiss the keyboard globally without the reference.
hope this will help you.
The easiest way to do this is to have a method for whenever you want to dismiss the keyboard that looks like this:
-(void)dismissKeyboard {
[firstField becomeFirstResponder];
[firstField resignFirstResponder];
}
You can check these questions:
Is it possible to make the iPhone keyboard invisible / remove it without resigning first responder?
Hide Input Keyboard on iPhone Without Knowing First Responder?
In summary:
You can call becomeFirstResponder on some other thing that you choose. It could be a UIViewController or a UIView. I had a similar problem before, I needed to make my keyboard go away when I was pushing my view controller back to its caller, without knowing which textfield was the first responder. Then, on viewWillAppear of my view controller which I was returning back, I called [self becomeFirstResponder] and the keyboard of the pushed view was gone. Because this made whichever text field was it loose being the first responder
In my own app when I had more than one text field and would like to make the keyboard go away regardless which of the fields called it, I would just wrote a method and let each and every of them resignFirstResponder.
I assume that as a programmer, you should have the clear knowledge how many text fields are on your view controller and how you can access them, otherwise it'll get messed up and you app won't look good... :-P
