Answer 1

It was answered here. Basically, you send a resignFirstResponder message to the UITextView. Of course, you will put that code on your button's delegate.

Answer 2

Try to put following code. It might work for you.
Put following variables in your viewController.h file
UIToolbar *keyboardToolbar;
id notisender;
BOOL isAlreadyResigned;
float kx,ky,kh,kw;
Now put following code in you viewController.m file.
- (void)viewDidLoad {
[super viewDidLoad];
}
-(void)viewWillAppear:(BOOL)animated{
isAlreadyResigned=YES;
[self keyboardToolbarShouldShow];
[self keyboardToolbarShouldShow];
[super viewWillAppear:animated];
}
-(void)viewWillDisappear:(BOOL)animated{
[self keyboardToolbarShouldNotShow];
[super viewWillDisappear:animated];
}
#pragma mark keyboardWillShow methods
-(void)keyboardToolbarShouldShow {
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWillShow:)
name:UIKeyboardWillShowNotification
object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardhide:)
name:UIKeyboardWillHideNotification
object:nil];
}
-(void)keyboardToolbarShouldNotShow {
[[NSNotificationCenter defaultCenter] removeObserver:self
name:UIKeyboardWillShowNotification
object:nil];
[[NSNotificationCenter defaultCenter] removeObserver:self
name:UIKeyboardWillHideNotification
object:nil];
if(!isAlreadyResigned){
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWillNotShow:)
name:UIKeyboardWillShowNotification
object:nil];
[GEEtxtMsg becomeFirstResponder];
}
}
-(void)keyboardWillShow : (NSNotification *)sender {
#try {
// NSLog(#"notification in first view");
for (UIWindow *keyboardWindow in [[UIApplication sharedApplication] windows]) {
for (UIView *keyboard in [keyboardWindow subviews]) {
NSLog(#"keyboard description - %#",[keyboard description]);
if([[keyboard description] hasPrefix:#"<UIKeyboard"] == YES) {
NSValue *v = [[sender userInfo] valueForKey:UIKeyboardBoundsUserInfoKey];
CGRect kbBounds = [v CGRectValue];
if(keyboardToolbar == nil) {
keyboardToolbar = [[UIToolbar alloc] initWithFrame:CGRectZero];
keyboardToolbar.barStyle=UIBarStyleBlackOpaque;
keyboardToolbar.tintColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:1];
UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStyleBordered target:self action:#selector(dismissKeyboard)];
UIBarButtonItem *flex = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
NSArray *items = [[NSArray alloc] initWithObjects:flex, barButtonItem, nil];
[keyboardToolbar setItems:items];
[items release];
}
[keyboardToolbar removeFromSuperview];
keyboardToolbar.frame = CGRectMake(0, 0, kbBounds.size.width, 45);
[keyboard addSubview:keyboardToolbar];
NSLog(#"x=%f y=%f width=%f height=%f",kbBounds.origin.x, kbBounds.origin.y, kbBounds.size.width, kbBounds.size.height);
kx=kbBounds.origin.x; ky=kbBounds.origin.y;

subKeyboard.bounds = CGRectMake(kbBounds.origin.x, kbBounds.origin.y - 45, kbBounds.size.width, kbBounds.size.height);
}
}
}
}
}
} #catch (NSException * e) {
NSLog(#"Problem in keyboardWillShow:%#",e);
}
}
-(void)keyboardWillNotShow : (NSNotification *)sender {
#try {

Answer 3

Here you can build a bar on a keyboard
Take static toolbar on xib and take one button and put it on toolbar, and make toolbar hidden ,now
write code in your method when you create a toolbar ,like if you want to create toolbar on textview begin editing method then,
- (BOOL)textViewShouldBeginEditing:(UITextView *)textView
{
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.26];
[tlBar setFrame:CGRectMake(0, 220, 320, 44)];
tlBar.hidden=NO;
[UIView commitAnimations];
}
And when you dismiss keyboard write this method and call this method when toolbar button pressed
-(IBAction)kbAway:(id)sender
{
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.3];
[tlBar setFrame:CGRectMake(0, 480, 320, 44)];
[UIView commitAnimations];
[txtviewmessage resignFirstResponder];
[txtsubject resignFirstResponder];
[txttemplatename resignFirstResponder];
}
Hope this will help you..
