Question

I have a project which Im working on this time and I would like to adjust the UITextView and UITextField above the keyboard when it appears, because when the keyboard appears the TextView and TextField and hidden behind it.

Here are my screen shots, Without Keyboard:

And with the keyboard,

This is a fairly common problem, there are all sorts of solutions to it. I put one together and made it part of my EnkiUtils package which you can download from https://github.com/pcezanne/EnkiUtils

Short version: You'll want to watch for keyboard events and call the Enki keyboardWasShown method, passing it the current view (and cell if you are in a table).

Long Version: Here's the text from my blog (http://www.notthepainter.com/expose-the-uitextfield-when-keyboard-is-shown/)

Notice that it is a class method, not an instance method. I keep a class called EnkiUtilities around to hold useful things. To call it, we first set up our observer:

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(keyboardWasShown:)
                                             name:UIKeyboardDidShowNotification object:nil];

And in the keyboardWasShown method we call our utilities method:

- (void)keyboardWasShown:(NSNotification*)aNotification
{
    [EnkiUtilities keyboardWasShown:aNotification view:self scrollView:myTableView activeField:activeField activeCell:activeCell];

}

So what is activeField and activeCell? Lets look at our textViewDidBeginEditing method to see how those are set

-(void)textViewDidBeginEditing:(UITextView *)sender
{           
    activeField = sender;

    if ([sender isEqual:descriptionTextView]) {
        activeCell = descriptionCell;
        if (shouldClearDescription) {
            [descriptionTextView initWithLPLStyle:@""];
            shouldClearDescription = false;
        } 
    }else if ([sender isEqual:hintTextView]) {
        activeCell = hintCell;
        if (shouldClearHint) {
            [hintTextView initWithLPLStyle:@""];
            shouldClearHint = false;
        }    
    } else {
        activeCell = nil;
    }
}

This method is called when a UITextField begins editing. I set the activeField to the sender and then I set the activeCell to the cell that corresponds to the field.

The only bit remaining is to restore the view when the keyboard disappears.

- (void)keyboardWillBeHidden:(NSNotification*)aNotification
{
    UIEdgeInsets contentInsets = UIEdgeInsetsZero;
    myTableView.contentInset = contentInsets;
    myTableView.scrollIndicatorInsets = contentInsets;
}

When you are working without a UITableView, just put the text fields into a UIScrollView and pass that, not the UITableView, to keyboardWasShown.
