#import "MainViewController.h"
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(keyboardDidShowNotification:) name:UIKeyboardDidShowNotification object:nil];
}
return self;
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
}
#pragma mark
- View lifecycle - (void)viewDidLoad {
[super viewDidLoad];
}
- (void)viewDidUnload {
[super viewDidUnload];
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
return [super shouldAutorotateToInterfaceOrientation:interfaceOrientation];
}
- (void) keyboardDidShowNotification:(NSNotification *)aNotification {
UIBarButtonItem *my0Button = [[UIBarButtonItem alloc] initWithTitle:#"0" style:UIBarButtonItemStyleBordered target:self action:#selector(addNumberToString:)];
UIBarButtonItem *my1Button = [[UIBarButtonItem alloc] initWithTitle:#"1" style:UIBarButtonItemStyleBordered target:self action:#selector(addNumberToString:)];
// UIToolbar *keyboardToolbar=nil;
UIToolbar *extraRow = [[UIToolbar alloc] init];
extraRow.barStyle = UIBarStyleDefault;
extraRow.translucent = YES;
extraRow.tintColor = [UIColor grayColor];
[extraRow sizeToFit];
NSArray *buttons = [NSArray arrayWithObjects: my0Button, my1Button, nil];
[extraRow setItems:buttons animated:YES];
NSArray *array = [[UIApplication sharedApplication] windows];
for (UIWindow* wind in array) {
for (UIView* currView in wind.subviews) {
if ([[currView description] hasPrefix:#"<UIPeripheralHostView"]) {
for (UIView* perView in currView.subviews) {
if ([[perView description] hasPrefix:#"<UIWebFormAccessory"]) {
[currView addSubview:extraRow];
[perView removeFromSuperview];
}
}
}
}
}
}
-(void) addNumberToString: (id) sender {
// HERE I WANT TO SHOW THE BUTTON TEXT TO TEXTFIELD,
}
#end

Answer 1

Finally i got output.
UIButton *clickButton=sender;
UILabel *label=clickButton.titleLabel;
NSString *buttonText=label.text;
NSString *javaScript = [NSString stringWithFormat:#"var textField = document.activeElement;" "textField.value = textField.value+'%#';" "document.activeElement.form.submit();", buttonText];
[webView stringByEvaluatingJavaScriptFromString:javaScript];
