I'm trying to programmatically click a UITextField after the user clicks on another UIButton, this way, when the user clicks the button, the keyboard will appear for the UITextField that the button corresponds to. What I'm trying to do is almost the opposite of resignFirstResponder. I haven't found any way to do this so far, anyone have any ideas?
Use UIResponder's becomeFirstResponder method.

When I cilck on a button on main toolbar, I am displaying a popup form (PXSmartPanel) with few fields on it. Whenever I click on the main toolbar button, I want first the control should go to the popup form and based on buttons on popup form (Ok/Cancel), it should perform the action.
However, I tried that but eventually when I click on button on main toolbar, it first executes the code behind for that button and then shows popup.
Any suggestions?
Found the solution. You can use AskExt method of your DAC class to show popup first and then execute your code.
You can also use px:PXSmartPanel with AskExt. With help of PXSmartPanel you can customize your screen, and even add some buttons to your pop up. Here I wrote "short" manual how to do it.
When I make a dialog using CDialog project of VC++,
I can not defocus any field on this dialog(CDialog).
What I want to do is how some field can be defocused
when I clicked the outside of this field with mouse.
Thanks for any advice and comments.
The only obvious question: WHY? Why do you want to de-focus from a control, and (possibly) not give focus to any control? Some control within the dialog should have a keyboard focus!
You can however, make a textbox, which would be outside the visible area of dialog, and SetFocus on that control, whenever you get WM_MOUSE* message(s) on the CDialog.
I have a table listing some strings, and what I want is when I tap the add button on the navigation bar, a keyboard with a textField would jump up, so I can input a string in the textField, then when I tap the return key, the keyboard disappear as well as the textField, and the new string is added to the table.
I already make up a nib file with a toolBar containing a textField, and I just failed to go on.
How can I implement this idea? Use the inputAccessoryView? If so, that means the inputAccessoryView of the textField which belongs to the toolBar is gonna be the toolBar itself!
This seem kind of weird and I have not been able to make it work till now.
Or is there another way for this idea?
Thanks a lot!
I've solved the problems by using notification instead of inputAccessoryView.
There is a sample code in XCode called "KeyboardAccessory", and it gives a good example about using keyboard notifications!
Or custom a view with a tab, and set it as the textField's inputAccessoryView, that would also work!
I have an android spinner which I call via the performClick method to show a list of items (the actual control is hidden from the user and is called from a checkbox, too complex to explain why I have done it this way).
If I do not want an item in the list, how can I dismiss the popup by clicking on the black area?
Does this make sense? :/
Edit: Sorry, forgot to mention that the users will not be able to operate the bottom buttons (device is going to be galaxy tab) as they will be covered up with protective layer due as they will be outdoors.
usually such a control is dismissed using the back key in the android applications. So I would suggest that you find a way to do it the same way on your control.
'Esc' button should do the same job..
I have attached a toolbar with a UITextField and UIButton to the keyboard when it becomes the first responder via the user taping inside the textfield
textField.inputAccessoryView = theToolbar;
Problem is, the toolbar disappears when the keyboard is dismissed, thus preventing any further input.
Any ideas on how to make the toolbar go back to the bottom of the screen rather than off it completely?
I'm thinking a delegate method might help but Im really not too sure. It seems once the inputAccessoryView always the inputAccessoryView :(
Cheers
The input accessory view is automatically dismissed with the input view (the keyboard, in this case). Generally you do not want to have an input accessory view in your view hierarchy. Instead, if you want your toolbar to scroll up when the keyboard is shown, you should follow the guidelines for Managing the Keyboard.
You could try using an additional toolbar that is offscreen as the inputAccessoryView, which could "fake" the appearance of what you are trying to do. Alternatively, have you tried adding the toolbar back to the bottom of the screen using
[self.view addSubview:theToolbar];
when the keyboard reaches the bottom of the screen? You can use keyboard notifications for this.
