I'm trying to end editing a UITextView when I click a UIControl on another cell.
If I tap on a cell containing the UIControl, the text view ends editing, as expected. However, when I tap on say, a UIStepper, the control responds fine but the text view continues in edit mode.
What mechanism would allow me to "catch" the tap anywhere outside the text view and allow me to exit edit mode? Thanks for the help.
You can use endEditing: method:
[self.view endEditing:YES];
In Swift:
self.view.endEditing(true)

I have a UIControl within a UIScrollView. I scrollview has a textfield. I want the text field to loose focus when the UIControl is touched.
This is the method the UIControl is hooked up to:
- (IBAction) clickedBackground
{
[self.view endEditing:YES]; //make the view end editing!
}
But, the UIControl doesn't seem to call this event when touched.
I did try this as suggested elsewhere, but to no avail:
[scroller setDelaysContentTouches:YES];
The touch event on your UIControl is getting conflicted with touch event of your UIScrollView.
If you just to loose focus of the text field you can use on a button tap.
[textField resignFirstResponder];
But ideal way is to loose focus when user taps anywhere outside the text field. This answer would help you to achieve this.
However, if you just want to resign the keyboard. Then make use of resignFirstResponder on a button tap. You can also look into UITextField input accessory view in order to display a button on the keyboard input view that user can tap on.
I want to realize the function: when I click a button, a interface of keyboard will come out in a dependent interface. How can I do it? Just for iOS.
You need to add to your current view UITextField with frame = CGRectZero, create a reference to that textField in code and then on pressing button call becomeFirstResponder on textField.
You need to add an UITextField to your view and call then [myTextfield becomeFirstResponder]; Its possible to set the hidden attrribute from UITextField to YES - so the user will never see the textfield. After Keyboard input is finished you can remove the UITextField with removeFromSuperview.
Maybe a little bit dirty,but thats the solution I used often. I wonder if the SDK provide another possibility.
My app has two text fields in it's detail split. The first text field will permit the user to enter data by keyboard but the second by a picker presented inside a popover. Anyway, I want to let the keyboard (that will appear after editing the first text field) get dismissed when I press the text field that uses a popover. I used resignFirstResponder and the keyboard stays in place but it's disabled, like when I tap any keyboard key nothing happens (even the key to dismiss the keyboard doesn't work). So how can I hide the keyboard?
You should use
[textField resignFirstResponder];
not releaseFirstResponder (there is no such method)
As George said, you should call resignFirstResponder
But actually you might want to look at using the inputView property of the textField instead of using the pickerview in a popover.
You can say:
textfield.inputView = pickerview;
Why do you need the second UITextField? If you're not going to allow user input something with keyboard use UIButton (probably with custom design), show picker on press and update button's text on changes in picker
the most simplest thing to resign responders
[self.view endEditing:YES];
I am hoping if someone can help me resolve an IOS/XCode question.
I need to have a UITextView created inside a UITableViewCell, this UITextView has responds to a user click, upon which a UIPopoverController will be displayed so that a sub-UITableView is displayed (inside the UIPopoverController) allowing a user to select from a list of choices (lines of text). After the user select the choice (one of the line of text), that line of text will then be displayed inside the said UITextView. First problem I am having is that when the user click on the UITextView the keyboard gets displayed instead of the UIPopoverController. How do I go about disabling ie. calling resignFirstResponder so that instead of the keyboard displaying, I get the UIPopoverController coming up instead. Would someone be kind enough to share similar codes? or point me to some sample of how this can be done? Thanks so much in advance.
You can use following delegate method to detect when textView is tapped and show your popOverController accordingly, return 'NO' in the delegate method so that no keyboard will appear...
- (BOOL)textViewShouldBeginEditing:(UITextView *)textView
{
// code to show popOverController
return NO;
}

Dismiss keyboard by touching background of UITableView
How do I make the keyboard go away when the user clicks somewhere else?
Note: I know how to make the keyboard disappear with sending the resignFirstResponder command to the UITextField. At present the "Done" button is connected to all the correct code to do this and this works.
I have a UITableView with different UITableViewCells, and if the user moves onto another cell I want the keyboard to disappear.
So what events do I also need to include the resignFirstResponder in, for the keyboard to disappear.
Suppose UITableViewCell A has the UITextField, and UITableViewCell B has a button. If the user presses the button in cell B, then I will need to send the command resignFirstResponder back to the UITextField in cell A. First of all the button has no idea which cell it should sent the command to, and second even if the button did know which cell to send the command to how would it?
There's no trivial way to do this. You can put a transparent set of "shield views" all the way around the text field that take up the rest of the screen, and use any touches on them to dismiss the keyboard.
You can create a generic 'hideKeyboard' method in which you can include all text fields that can be first responders. For example,
-(void) hideKeyboard {
[textFieldName resignFirstResponder];
[textFieldSurname resignFirstResponder];
for (UITextField * txtField in arrTextFields) {
[txtField resignFirstResponder];
}
}
Then, at various sections in your class, depending on the functionality required, call;
[self hideKeyBoard];
This simple method means you won't need to keep track of the individual item that 'has the focus' / first responder status.
How to touch any part of the screen to make the keyboard go away
To touch somewhere outside the UITableView and have the keyboard disappear, place an invisible button on top of the 'touch area' that you want to respond to. Then, simply call [self hideKeyboard] from the touch event for that invisible button. Using IB, drag a new rounded button onto your view, then size it to take up the full size of the screen. Next,drag the button up or down the controls list in the IB document window so that button is behind all text fields and buttons, but in front of anything else (like images etc.). Finally, change the type of the button to 'Custom' to make it invisible, but still respond to events. Now all you have to do is to connect the new button's 'touch up inside' event to trigger the 'hideKeyboard' method.
