Dismissing keyboard on tapping outside the table - ios

Before you dismiss my question as being a duplicate of this one: iphone, dismiss keyboard when touching outside of UITextField
The issue for me is that my textfield is part of my prototype cell which has its own subclass of uitableview cell and so I'm not sure how to reference the textfield when trying to resign the first responder. SO, I can't just do this:
-(void)dismissKeyboard {
[aTextField resignFirstResponder];
}
How would I get across this situation?
Thanks

Try this code, it's very useful:
-(void)touchesBegan :(NSSet *)touches withEvent:(UIEvent *)event
{
[aTextField resignFirstResponder];
[super touchesBegan:touches withEvent:event];
}

I think dismissing keyboard on tapping outside the table view cell is not good. User may accidently touching outside or he can scroll while entering text right?. You can use the UITextFieldDelegate to dissmiss keyboard
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder]
}

If I got you right you want to resign keyboard wile tapping on outSide of textfield but you don't have reference of your textfield.
Try this;
Take global textField, lets call it reftextField
Now in textFieldDidBeginEditing set referenced text field to
- (void) textFieldDidBeginEditing:(UITextField *)textField{
reftextField = textField;
}
Now you can happily use on any button clock, (adding a transparent button on begin editing recomended)
- (void)dismissKeyboard {
[reftextField resignFirstResponder];
}
Or for resigning done button try this.
//for resigning on done button
- (BOOL) textFieldShouldReturn:(UITextField *)textField{
[textField resignFirstResponder];
return YES;
}

Setting the delegate of a UITextField programatically from a UIView

I have a custom UIView which creates a UITextField as a subview while the application is running. I have been stuck on this for hours now, but cannot figure out how to create delegates to hide the keyboard and determine when the "done" button is pressed. I'm still pretty new to iOS development, so any help here would be greatly appreciated.
Thanks.
u can do this set
yourtextfieldname.delegate=self;
when u hide your keyboard.. then u can call that textfield and do this code...
[txtfieldname resignFirstResponder];
or u can try this.. also
- (void)textFieldDidEndEditing:(UITextField *)textField
{
[yourtextfieldname resignFirstResponder];
}
or best method
-(BOOL)textfieldshouldreturn:(UITextField *)textField
{
[textField resignFirstResponder];
}
If you are using keyboard done button, set the delegate to the textfield
texfield.delegate = self;
then the below method will be called when done button is clicked
-(BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
If you are using done button on a toolbar created by you then add a target to the doneButton then call below method in the selector
[textField resignFirstResponder];
This may help you.First use UITextFieldDelegate and set
yourtextfield.delegate=self;
Then use
- (void)textFieldDidEndEditing:(UITextField *)textField
{
[yourtextfield resignFirstResponder];
}
// and also you can use this
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[yourtextfield resignFirstResponder];
return YES;
}

UITextField triggers unwanted segue when keyboard is dismissed

I'm using Storyboard with this project and have a UITextField inside a view. The user is able to type in a search term, press return and a segue to a resultsViewController occurs as intended.
The problem I am having is that if for any reason the keyboard gets dismissed, the segue occurs automatically. For example, if the user taps the iPad's drop keyboard key, the segue occurs without a search term... or if the user taps outside the UITextField, the keyboard drops (as intended), but the segue also occurs (not intended).
Here's are the methods I'm using (the UITextField's delegate is set in storyboard); also, I've put in "resignFirstResponder" and "endEditing: YES" messages in several places as I was trying to figure out a solution. Sorry for the mess:
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
if ([textField.text isEqualToString:#""]) {
[textField resignFirstResponder];
return NO;
}
self.clueString = textField.text;
[textField resignFirstResponder];
return YES;
}
- (BOOL) textFieldShouldEndEditing:(UITextField *)textField {
[self.view resignFirstResponder];
return YES;
}
-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
[self.view endEditing:YES];
}
Well, I feel silly but I'll answer my question in case anyone else has this problem.
To control when the segue should or should not occur, I needed to implement the following method:
-(BOOL) shouldPerformSegueWithIdentifier:(NSString *)identifier sender:(id)sender {
if ([self.searchField.text isEqualToString:#""]) {
return NO;
}
return YES;
}
Have you tried setting this method to always return no? You might need to have a check in there on whether or not to search. (Like your above method)
- (BOOL) textFieldShouldEndEditing:(UITextField *)textField {
[self.view resignFirstResponder];
return YES;
}

Keyboard doesn't dismiss for TextField in UITableViewCell

I have a strange problem with the iOS Keyboard.
In my app, I am using UITextFields inside some UITableViewCells. I want to dismiss the keyboard if the current textfield loses its focus.
This is what I've done so far:
Set up the <UITextFieldDelegate> and add [textField resignFirstResponder] to textFieldDidEndEditing:
-> textFieldDidEndEditing gets called, but the keyboard stays.
Added all TextFields to an array, looped through all objects and call resignFirstResponder
-> No effect
Called [self.tblView endEditing:YES] inside textFieldDidEndEditing.
-> Keyboard didn't disappear.
But dismissing the keyboard by using the Done-Button works perfectly (using textFieldShouldReturn)
What am I doing wrong?
Edit: I've made a video of my problem: http://www.youtube.com/watch?v=Zuz5rCv2GCo
try implementing following:
-(void)textFieldDidBeginEditing:(UITextField *)textField
{
[textField becomeFirstResponder];
}
-(void)textFieldDidEndEditing:(UITextField *)textField
{
[self resignFirstResponder];
}

Best method to save UITextField test: textFieldShouldReturn or textFieldDidEndEditing

my objective simply to save text on UITextField after user click done button on keyboard. I could either do this in extFieldShouldReturn or textFieldDidEndEditing: does it make any difference ? or there a better approach ?
Thanks!!
textFieldShouldReturn is only called if the user presses the return key. If the keyboard is dismissed due to some other reason such as the user selecting another field, or switching views to another screen, it won't be but textFieldDidEndEditing will be.
The best approach is to use textFieldShouldReturn to resign the responder (hide the keyboard) like this:
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
//hide the keyboard
[textField resignFirstResponder];
//return NO or YES, it doesn't matter
return YES;
}
When the keyboard closes, textFieldDidEndEditing will be called. You can then use textFieldDidEndEditing to do something with the text:
- (BOOL)textFieldDidEndEditing:(UITextField *)textField
{
//do something with the text
}
But if you actually want to perform the action only when the user explicitly presses the "go" or "send" or "search" (or whatever) button on the keyboard, then you should put that handler in the textFieldShouldReturn method instead, like this:
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
//hide the keyboard
[textField resignFirstResponder];
//submit my form
[self submitFormActionOrWhatever];
//return NO or YES, it doesn't matter
return YES;
}

Keyboard dismissing problem - Objective C

I have set the delegate of my textfield to self and I have added the delegate for it in the .h, but I have a problem. I want the keyboard to hide If I click anything but the textfield in the view. Is this possible? If so, how would I do it?
I found a simpler way to hide the keyboard and it works when you click on the screen way.
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
// endEditing: This method looks at the current view and its subview hierarchy for the text field that is currently the first responder.
// If it finds one, it asks that text field to resign as first responder
[[self view] endEditing:TRUE];
}
You can do some "hacking"... Like this:
- (void)textFieldDidBeginEditing:(UITextField *)textField{
//glass is a class's property
if(glass){
self.glass=nil;
}
glass=[[UIButton alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; //put the size you want.
[glass addTarget:self action:#selector(hideGlass) forControlEvents:UIControlEventTouchUpInside];
[self.view insertSubview:glass belowSubview:textField];
}
-(void)hideGlass{
//remove your glass.
[glass removeFromSuperview];
//your textField resigns first responder.
if([myTextField canResignFirstResponder]){
[myTextField resignFirstResponder];
}
}
So basically what you do, is to add a dummy button right bellow your textField. So when you touch anything else, excepts your textField, he will make your textField resignFirstResponder and removes himself from the view.
Edit 1 ( the tweek) You just need to replace this:
if(glass){
self.glass=nil;
}
for this:
if(glass){
[glass release];
glass=nil;
}
You just need to implement the following delegate methods:
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
[textField resignFirstResponder];
return YES;
}
- (BOOL)textFieldShouldEndEditing:(UITextField *)textField {
[textField resignFirstResponder];
return YES;
}
If you have an IBOutlet for the UITextField, you can dismiss the keyboard using [textField resignFirstResponder];. This being said, you will have to implement event listeners for everything else on the view. If you want the keyboard to hide when the user taps the view's background, it can be done through a touch event in the view controller's implementation:
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
[textField resignFirstResponder];
}
If you have any buttons or subviews, you will have to implement individual touch events or actions for those as well.
