Dismiss keyboard on touch anywhere outside UITextField
MyViewController in interface builder :
In my custom TableViewCell I have a TextField. My plan is disappear KeyPad when User Clicks outside the touchpad.
I could not make it works using UITapGestureRecognizer
in viewDidLoad:
UITapGestureRecognizer *gestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(hideKeyboard)];
[self.tableView addGestureRecognizer:gestureRecognizer];
Then how should I make it work with cell.TextField ?
I read about this solution here:
[self.view endEditing:YES];
or
[[self.tableView superView] endEditing];
I couldn't make it work neither. Where should I use them?
Or if you have any better way, please let me know.
Edit
I could not make it work:
#property (nonatomic, strong) UITextField *cellTextField;
in viewDidLoad:
UITapGestureRecognizer *gestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(hideKeyboard)];
[self.settingTableView addGestureRecognizer:gestureRecognizer];
And we have:
- (void) hideKeyboard {
[self.cellTextField resignFirstResponder];
}
And :
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
SettingTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
self.cellTextField = cell.dataEdit;
What is my fault?

Answer 1

you could add a property to your view controller, say
#property (nonatomic, strong) UITextField *cellTextField
and then assign cell.TextField to it.
in hideKeyboard: you can dismiss the keyboard by doing
[cellTextField resignFirstResponder];
You should call resignFirstResponder on the textField itself, not the controller's view.

Answer 2

Add [cellTextField resignFirstResponder]; hope this works...
Maybe look at UITextFieldDelegate, and in particular - (BOOL)textFieldShouldReturn:(UITextField *)textField

Answer 3

You Can hide Keyboard if You Put the Whole Screen Custom UIButton.Then Attached this Method With this Custom UIButton.set the UITextField tag =1 in Interface builder before implementation of this method.
-(IBAction)HideKeyboard
{
[[self.view viewWithTag:1]resignFirstResponder];
}
Note: if You Want to hide keyboard by Click in CustomCell then Put this UIButton there or You Can Call this Method using Gesture Recognization as you did in Your Code without Using Custom UIButton.
And also make sure You Connect UITextField delegate.Hope this Work .

Answer 4

You may try this.
- (void) hideKeyboard {
[self.view endEditing:YES];
}

Answer 5

You can achieve this task by inserting the following method
You must implement UITextFieldDelegate
you must set a tag for the textfield in the storyboard or in when you start loading the cells of the table
-(void)textFieldDidBeginEditing:(UITextField *)textField
{
self.currentIndexPath = [(UITableView*)textField.superview.superview.superview indexPathForCell:(UITableViewCell*)textField.superview.superview];
self.currentTableView = (UITableView*)textField.superview.superview.superview;
self.keyboardIsShown = YES;
}
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *touch = [touches anyObject];
CGPoint currentPoint = [touch locationInView:self.view];
if(self.keyBoardIsShown)
{
[self dismissKeyboard:currentPoint UsedTableView:self.myTableView IndexPathForRow:self.currentIndexPath TexFieldTag:tag];
self.keyBoardIsShown = NO;
}
}
-(void)dismissKeyboard:(CGPoint)currentPoint UsedTableView:(UITableView*)table IndexPathForRow:(NSIndexPath*)indexPath TexFieldTag:(int)tag
{
UITableViewCell *cell = [table cellForRowAtIndexPath:indexPath];
if(!CGRectContainsPoint([self.view convertRect:[cell viewWithTag:tag].frame fromView:[cell viewWithTag:tag].superview.superview], currentPoint))
{
[(UITextField*)[cell viewWithTag:tag] resignFirstResponder];
}
}
