How can I set editing= NO; in UITextField ?
You can set it like
[yourTextField setUserInteractionEnabled:NO];
Swift Update:
yourTextField.setUserInteractionEnabled = false
Also you can implement the protocol and implements this method:
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
return NO;
}
Doing this any UITextField in associated XIB will be editable, but you gain the hability for checking any properties or doing some business logic inside for enable/disable text editing.
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
if (condition)
return NO;
else
return YES;
}
I hope this helps you
Regards!
If you mean you want to hide the UITextField, just do:
[UITextField resignFirstResponder];
Use this piece of code
[textField setEditable:NO];

In my iPad app I have two textfields. One displays the normal, default textfield and the other should display a picker as its input view.
Problem is, once I use the txt1 which displays default keyboard and then when I touch the 2nd textField the txt1 keyboard is staying visible.
I have also written [txt1 resignFirstResponder]; [txt2 resignFirstResponder]; while displaying the picker.
I have checked the txt1 IBOutlet connection and the delegate assignment, those seem to be correct.
What am I missing?
Write the following code :
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
if(textField == txt1)
{
return YES;
}
else
{
return NO; // Write the code for displaying UIPickerView instead of the Keyboard.
}
}
Hope this might solve your issue......
txt2.userInteractionEnabled = NO;
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
if(textField == txt1)
{
[txt2 resignFirstResponder];
// code for Hide Picker
return YES;
}
else {
// [txt2 resignFirstResponder];
[txt1 resignFirstResponder];
// code for go in picker
return YES;
}
}

You have to implement below method to resign Keyboard......
-(BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
Have u implemented this method ??
-(BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
In your viewDidLoad method write this,
txt2.inputView = pickerView;
and other resignFirstResponder codes should be placed correctly , by this on Tapping txt2, you will directly get pickerview instead of Keyboard.
did you implement the delegates property of UITextFieldDelegates to in the header file, if not do that and check
Already the second day and cannot figure out the problem,
I've UITabelView with Custom UICellViews, each custom UICellView consists of UILabel and UITextField.
Custom UICellView object allocs UITextField and UILabel in its init method and are released in dealloc.
The number of custom UICellViews in UITableView is 6.
The user scenario is following
When user clicks from from 1 to 5 UITextFields virtual keyboard opens and user types some text
When user clicks on the 6th UITextField if virtual keyboard is active, it should be hidden, and if it is hidden it shall not be displayed.
As implement UITextFieldDelegate protocol in my UIViewController class and set the delegate of each UITextField to self.
My delegate methods are following
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
if (textField.tag != 6) {
return YES;
} else {
[textField resignFirstResponder];
return NO;
}
}
-(BOOL) textFieldShouldEndEditing:(UITextField *)textField {
[textField resignFirstResponder];
return YES;
}
-(void) textFieldDidBeginEditing:(UITextField *)textField {
/* Some code */
}
-(void) textFieldDidEndEditing:(UITextField *)textField
{
[textField resignFirstResponder];
}
All the functions are properly !
So now, the virtual keyboard is never get hidden, why this happens ?
PS. Similar code has worked on iPhone but this issue exists on iPad.
You need to know which textfield was last used! so you can do [lastUsedTextField resignFirstResponder]
There is a dirty, but working trick.. you can make your textfield the new active UITextField and call resignFirstResponder in the next cycle immediately:
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
if (textField.tag != 6) {
return YES;
} else {
// this will schedule keyboard dismissal for the current text field
dispatch_async(dispatch_get_main_queue(), ^{
[textField resignFirstResponder];
});
return YES; // -> make this one active
}
}
did you seted action for textField?
[YourTextField addTarget:self action:#selector(textFieldDoneEditing:) forControlEvents:UIControlEventEditingDidEndOnExit];
PS set any selector for any ControlEvent
I want to ask that how can I call a method as I do click(touch for start writing) in iphone UITextField, as like we click UIButton and put method in "addTarget", is there any way for UITextFields ?
implement a UITextFieldDelegate and do whatever you want to do in - (BOOL)textFieldShouldBeginEditing:(UITextField *)textField or - (void)textFieldDidBeginEditing:(UITextField *)textField
You should use the first method if you want to stop the textfield from behaving like a textfield. For example if you want to open the textfield editor in a modal view. You can return NO there if you don't want this behavior.
Edit: Here is the code to call myMethod:
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
[self myMethod];
return YES;
}
You can set textField's delegate and implement textFieldShouldBeginEditing: method in it - that method will get called when user taps the field and before it goes into editing.
See UITextFieldDelegate reference for more methods available.
[textField addTarget:self action:#selector(myMethod:) forControlEvents:UIControlEventEditingChanged];
-(void) myMethod:(id)sender
{
UITextField* textField = (UITextField *)sender;
}
i think this will help..!!
You can code as,
[YourTextField addTarget:self action:#selector(myMethod:) forControlEvents:UIControlEventEditingDidBegin];
-(void)myMethod
{
[YourTextField resignFirstResponder];
//Do whatever you want
}
I'm wondering if there is a way to have the UITextField clear button 'always visible'
textfield.clearButtonMode = UITextFieldViewModeAlways;
doesn't seem to work
.. and if it is possible to dismiss the keyboard using the button?
Thanks in advance.
Like mentioned before it seems apple is setting the textfield focus after you clear the field.
The solution is quite simple. Just clear the field yourself, resignFirstResponder and return NO
-(BOOL)textFieldShouldClear:(UITextField *)textField
{
textField.text = #"";
[textField resignFirstResponder];
return NO;
}
In your delegate, the function
- (BOOL)textFieldShouldClear:(UITextField *)textField
is called when the users wants to clear the textfield. If you return YES and call
[textField resignFirstResponder];
the keyboard should go away. I don't know about the clearButtonMode, other than that you may want to set it early, preferably before adding the view to its superview.
edit To make sure you really resign the responder, try doing it just a little later:
[textField performSelector:#selector(resignFirstResponder) withObject:nil afterDelay:0.1];
The delay didn't work well for me. Instead I added an instance variable to the delegate:
BOOL cancelEdit;
Then in the delegate implementation:
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
if (cancelEdit) {
cancelEdit = NO;
return NO;
} else {
return YES;
}
}
- (BOOL)textFieldShouldClear:(UITextField *)textField
{
cancelEdit = YES;
return YES;
}
UITextFieldDelegate textFieldShouldClear
- (BOOL)textFieldShouldClear:(UITextField *)textField {
[textField] resignFirstResponder];
return YES;
http://developer.apple.com/iphone/library/documentation/uikit/reference/UITextFieldDelegate_Protocol/UITextFieldDelegate/UITextFieldDelegate.html#//apple_ref/occ/intfm/UITextFieldDelegate/textFieldShouldClear:
I discovered this odd behavior was caused by a competing gesture recognizer that resigned the first responder before the keyboard before textFieldShouldClear: was called. It seemed to be corrupting the first responder.
If you've set it up this way, ensure that cancelsTouchesInView on your gesture recognizer is set to YES. This way you shouldn't need to do anything special in the textFieldShouldClear: or textFieldShouldBeginEditing: delegate methods.
I want to send the keyboard down after writing in textField.
How can I do this?
Any help would be appreciated.
Implement the - (BOOL)textFieldShouldReturn:(UITextField *)textField; delegate method and tell the text field to resign it's first responder status.
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
STEP-1:
You need to set the delegate of the textField to File's Owner (using interface builder)
or
textField.delegate = self; from the viewController programmatically first
STEP-2:
And you implement the method:
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
Hope this helps.
- (IBAction)textFieldDoneEditing:(id)sender{
[sender resignFirstResponder];
}
connect this to didEndOnExit action of your textfield
