Iam developing one application.In that i use the textview.But when we click on textview,or completion of entering the text into textview,textview delegate methods are not fired.Ias writtent he textview.delegate=self also.But they are not firing.So pleas etell me how to solve this one
The UITextViewDelegate methods do not handle dismissal of the keyboard: you must do that yourself, by calling:
[textView resignFirstResponder];
This will then trigger the textViewShouldEndEditing:(UITextView *)textView delegate method. What you need to do is call the resignFirstResponder method in response to whatever actions you require - if this is tapping outside the text view you'll need to create a gesture recognizer / button / whatever to pick up that tap and call resignFirstResponder.
You can also use Keyboard notifications like:
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWillShow)
name:UIKeyboardWillShowNotification object:nil];
and in -(void) keyboardWillShow {} set [myTextField resignFirstResponder];
hope this helps.

I am currently presenting a security code view controller that contains a UITextField in which the user is supposed to enter a passcode. This security code view controller is presented in its own window which has a "windowLevel = UIWindowLevelAlert + 1;" because i want to hide potential UIAlertView or other windows that could be present already displayed.
The problem comes when i call the resignFirstResponder method on the textfield, it seems that the keyboard is dismissed without the usual animation.
I tried to register to the various keyboard notification, and checked the UIView areAnimationsEnabled property and it returns YES.
So if anybody already had this issue, you're welcome :)
UIKeyboardAnimationDurationUserInfoKey is a constant string identifier the animation duration, so there is where of enabling and disabling the animation.
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(willHideKeyboard:)
name:UIKeyboardWillHideNotification
object:nil];
- (void)willHideKeyboard:(NSNotification *)notification {
[UIView setAnimationsEnabled:NO];
}
This question already has answers here:
how to resign keyBoard as a firstResponder from a textView?
(4 answers)
Closed 9 years ago.
I am pretty new in this programming, I am making a app in Xcode 4.6 with custom keyboard.
I made the keyboard and it is working great but I need to disable the default keyboard when I hit the text box, how do i do that? Like I said I am new to this so any help would be great.
So, you have two choices.
1- UITextField has a delegate methods called
-(void)textFieldDidBeginEditing:(UITextField *)textField this is the method when you hit your textField. So you need to hide your default keyboard here.
-(void)textFieldDidBeginEditing:(UITextField *)textField
{
[self.yourTextField resignFirstResponder];
}
2- There is a notification called UIKeyboardWillShowNotification which is posted immediately to the display of keyboard. So, You can use NSNotificationCenter to do your job when you received notification. So, in your viewDidLoad method :
- (void)viewDidLoad
{
[super viewDidLoad];
[[NSNotificationCenter defaultCenter]addObserver:self selector:#selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
}
then implement your selector.
-(void)keyboardWillShow:(id)sender
{
[self.yourTextField resignFirstResponder];
}
I've tested both of them, i think they are working well.
I hope that helps.
Do you just want to hide the keyboard or want to show your custom keyboard also? To show your custom keyboard instead of default one, use inputView property of textfield and set your keyboard to it. textField.inputView = customKeyBoard.
Is it possible to disable the keyboard from showing when a webpage element is selected inside a UIWebView?
Register for a keyboard notification:
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(keyboardWillShow) name:UIKeyboardWillShowNotification object:nil];
And then you can stop it from showing by placing the following code in keyboardWillShow :
UITextField *dummyTextField = etc.
//Basically, create a dummy uitextfield that you never show.
//I can't remember all the syntax :)
[dummyTextField becomeFirstResponder];
[dummyTextField resignFirstResponder];
//Keyboard should be gone. Hoorah!
Not sure 100% if this will work without flaws. If the keyboard starts to animate then hides itself again, you could use
[UIView enableAnimations:NO];
If the keyboard doesn't like being resigned while it's showing then you could try changing the inputView property of the dummy textField to some dummy UIView instead.
Hopefully this should get you somewhere!
I have 2 views:
OneViewController
TwoViewController
TwoViewController has an IBAction which plays a sound. Once the user has pressed the button on TWoViewController I want a UILabel which will appear on OneViewController saying that the sound has been played.
Thanks for the help
All you have to do is reference one viewController in the other one, that way you can call it's methods. Or you can simply create a delegate.
One possible solution is to use notifications.
In the action that plays a sound, post a notification to the default notification center that indicates the sound has played.
[[NSNotificationCenter defaultCenter] postNotificationName:"playSoundNotification"
object:self
userInfo:nil];
When OneViewController is created, have it register for the notification.
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(showPlayedLabel:)
name:"playSoundNotification"
object:nil];
When it receives the notification -- in showPlayedLabel: -- display the UILabel. Note that showPlayedLabel must follow the appropriate signature format.
- (void) showPlayedLabel:(NSNotification*) aNotification;
I have several UITextFields on my view (each inside a UITableViewCell). When the keyboard is fired from any of the textfields, I need to make some animations, mainly to change the frame of the UITableView. The same must happen when the keyboard will hide.
I have done the animation, so this is not the issue here.
Now, I use NSNotificationCenter to catch displaying/hiding of the keyboard:
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(keyboardWillShow) name:UIKeyboardWillShowNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(keyboardWillHide) name:UIKeyboardWillHideNotification object:nil];
The problem is when the keyboard is visible (a textfield is used) and I press inside another textfield. Usually for this thing keyboard will not hide, but will stay visible.
It works fine in iOS 4, but the problem comes in 3.1.3 (this is the version that I can test - possibly any version below 3.2). In versions older than 3.2 changing focus from a textfield directly to another textfield will fire the UIKeyboardWillHideNotification and UIKeyboardWillShowNotification.
Anyone knows a way to perform some animation when the keyboard will really show/hide, without the NSNotificationCenter?
Or how can I overcome this issue with versions lower than 3.2?
Thanks.
What you can do is set the textfield's/textview's delegate to the current view controller and implement these 2 methods
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
_keyboardWillHide = NO;
return YES;
}
- (BOOL)textViewShouldBeginEditing:(UITextView *)textView
{
_keyboardWillHide = NO;
return YES;
}
After that in your method that get's triggered by the UIKeyboardWillHideNotification notification you can do something like
if (_keyboardWillHide) {
// No other textfield/textview was selected so you can animate the tableView
...
}
_keyBoardWillHide = YES;
Let me know if that works for you.
Rather than avoid the notifications, you can set an NSTimer for 0.1 second to do your animations in one, and in the other, cancel the timer, that way if you get UIKeyboardWillHide and UIKeyboardWillShow both at once, you'll get a chance to cancel the timer. If you don't get both, the timer will reach zero and the animations will be carried out.
Consider using the UITextFieldDelegate protocol. The method textFieldShouldBeginEditing: will fire off before the notification and it will fire off everytime you go into the text field.
