Question

I am having one registration form which are having five textfield in which one textfield is phonenumber textfield and we take keyboard for that uikeyboardtypenumberpad, but no done button on numberpadkeyboard. I am adding done button but button is added for all textfields but I want only for phonenumber field.
My code is:
- (void)viewDidLoad
{
self.navigationController.navigationBarHidden = NO;
self.navigationController.navigationBar.tintColor = [UIColor blackColor];
UIBarButtonItem *leftButton = [[UIBarButtonItem alloc]initWithTitle:#"Back" style:UIBarButtonItemStyleBordered target:self action:#selector(backButtonAction)];
self.navigationItem.leftBarButtonItem = leftButton;
// UIBarButtonItem *rightbarButton = [[UIBarButtonItem alloc]initWithTitle:#"About" style:UIBarButtonItemStyleBordered target:self action:#selector(AboutButtonAction)];
// self.navigationItem.rightBarButtonItem = rightbarButton;
[super viewDidLoad];
NSLog(#"Events Id is : %#", particularEventId);
phoneNumber = [[UITextField alloc] initWithFrame:CGRectMake(56, 223, 220, 31)];
phoneNumber.borderStyle = UITextBorderStyleRoundedRect;
phoneNumber.keyboardType = UIKeyboardTypeNumberPad;
phoneNumber.returnKeyType = UIReturnKeyDone;
phoneNumber.textAlignment = UITextAlignmentLeft;
[self.view addSubview:phoneNumber];
// add observer for the respective notifications (depending on the os version)
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 3.2) {
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardDidShow:)
name:UIKeyboardDidShowNotification
object:nil];
} else {
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWillShow:)
name:UIKeyboardWillShowNotification
object:nil];
}
}
- (void)addButtonToKeyboard {
// create custom button
UIButton *doneButton = [UIButton buttonWithType:UIButtonTypeCustom];
doneButton.frame = CGRectMake(0, 163, 106, 53);
doneButton.adjustsImageWhenHighlighted = NO;
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 3.0) {
[doneButton setImage:[UIImage imageNamed:#"DoneUp3.png"] forState:UIControlStateNormal];
[doneButton setImage:[UIImage imageNamed:#"DoneDown3.png"] forState:UIControlStateHighlighted];
} else {
[doneButton setImage:[UIImage imageNamed:#"DoneUp.png"] forState:UIControlStateNormal];
[doneButton setImage:[UIImage imageNamed:#"DoneDown.png"] forState:UIControlStateHighlighted];
}
[doneButton addTarget:self action:#selector(doneButton:) forControlEvents:UIControlEventTouchUpInside];
// locate keyboard view
UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1];
UIView* keyboard;
for(int i=0; i<[tempWindow.subviews count]; i++) {
keyboard = [tempWindow.subviews objectAtIndex:i];
// keyboard found, add the button
if(keyboard == phoneNumber)
{
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 3.2) {
if([[keyboard description] hasPrefix:#"<UIPeripheralHost"] == YES)
[keyboard addSubview:doneButton];
} else {
if([[keyboard description] hasPrefix:#"<UIKeyboard"] == YES)
[keyboard addSubview:doneButton];
}
}
}
}
- (void)keyboardWillShow:(NSNotification *)note {
// if clause is just an additional precaution, you could also dismiss it
if ([[[UIDevice currentDevice] systemVersion] floatValue] < 3.2) {
[self addButtonToKeyboard];
}
}
- (void)keyboardDidShow:(NSNotification *)note {
// if clause is just an additional precaution, you could also dismiss it
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 3.2) {
[self addButtonToKeyboard];
}
}
- (void)doneButton:(id)sender {
NSLog(#"doneButton");
NSLog(#"Input: %#", phoneNumber.text);
[phoneNumber resignFirstResponder];
}

I used this code for my project, I think it isn't optimized but it works very well.
.h
BOOL firstTime;
BOOL add;
BOOL keyboardOpened;
.m
- (void)viewDidLoad
{
[super viewDidLoad];
firstTime = TRUE;
add = TRUE;
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(keyboardDidShow:) name:UIKeyboardDidShowNotification object:nil];
}
- (void)addButtonToKeyboard {
// create custom button
UIButton *doneButton = [UIButton buttonWithType:UIButtonTypeCustom];
doneButton.frame = CGRectMake(0, 163, 106, 53);
doneButton.adjustsImageWhenHighlighted = NO;
[doneButton setImage:[UIImage imageNamed:#"DoneUp3.png"] forState:UIControlStateNormal];
[doneButton setImage:[UIImage imageNamed:#"DoneDown3.png"] forState:UIControlStateHighlighted];
doneButton.tag = 3;
[doneButton addTarget:self action:#selector(doneButton:) forControlEvents:UIControlEventTouchUpInside];
// locate keyboard view
UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1];
UIView* keyboard;
for(int i=0; i<[tempWindow.subviews count]; i++) {
keyboard = [tempWindow.subviews objectAtIndex:i];
// keyboard found, add the button
if ([[keyboard description] hasPrefix:#"<UIPeripheralHost"] == YES && add) [keyboard addSubview:doneButton];
}
}
- (void)removeButtonFromKeyboard
{
// locate keyboard view
UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1];
UIView* keyboard;
for(int i=0; i<[tempWindow.subviews count]; i++) {
keyboard = [tempWindow.subviews objectAtIndex:i];
// keyboard found, remove the button
if([[keyboard description] hasPrefix:#"<UIPeripheralHost"] == YES) [[keyboard viewWithTag:3] removeFromSuperview];
}
}
- (void)doneButton:(id)sender {
[firstResponder resignFirstResponder];
if (![[[UIDevice currentDevice] model] isEqualToString:#"iPad"] && ![[[UIDevice currentDevice] model] isEqualToString:#"iPad Simulator"])
{
[self removeButtonFromKeyboard];
firstTime = TRUE;
}
}
- (BOOL)textFieldShouldReturn:(UITextField *)theTextField {
[theTextField resignFirstResponder];
return YES;
}
- (void)textFieldDidBeginEditing:(UITextField *)textField
{
firstResponder = textField;
for (int i = 0; i < [[[profile operationObject] keys] count]; i++)
{
if ([[[self.tableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:i inSection:0]] viewWithTag:1] isEqual:textField])
{
editingPath = [NSIndexPath indexPathForRow:i inSection:0];
break;
}
}
if (![[[UIDevice currentDevice] model] isEqualToString:#"iPad"] && ![[[UIDevice currentDevice] model] isEqualToString:#"iPad Simulator"])
{
if(!firstTime)
{
if(textField.keyboardType == UIKeyboardTypeNumberPad)
{
add = TRUE;
[self addButtonToKeyboard];
}
else
{
add = FALSE;
}
}
else
{
firstTime = FALSE;
if(textField.keyboardType != UIKeyboardTypeNumberPad)
{
add = FALSE;
}
}
keyboardOpened = TRUE;
}
}
- (void)keyboardDidShow:(id)sender
{
if (![[[UIDevice currentDevice] model] isEqualToString:#"iPad"] && ![[[UIDevice currentDevice] model] isEqualToString:#"iPad Simulator"])
{
NSLog(#"%#",[[UIDevice currentDevice] model]);
[self addButtonToKeyboard];
keyboardOpened = TRUE;
}
}
- (void)textFieldDidEndEditing:(UITextField *)textField
{
