How to hide keyboard when you press the button

[jessesar]

does anyone knows how to hide keyboard when you click a button?

[bikr]

- (BOOL)textFielsShouldReturn:(UITextField *)textField {
  [textField] resignFirstResponder];
  return YES;

[jessesar]

where should i place it?

[bikr]

In your view.m where the text entry is located somewhere at the bottom probably out of the way but before the @end

[jessesar]

then i get 2 errors and 1 warning

[bikr]

what are they? Post your entire code between code brackets [ code ] code goes here [ /code ]

[jessesar]

i am practicing with textfields, just for practice:

#import "lockerViewController.h"

@implementation lockerViewController
- (IBAction)lock {
// Actions etc..
}
@end

when you press the button the lock action will be called.
this is just for practice
the textField is called codeField

[bikr]

Basically..

#import "lockerViewController.h"

@implementation lockerViewController
- (IBAction)lock {
// Actions etc..
}

- (BOOL)textFielsShouldReturn:(UITextField *)textField {
  [textField] resignFirstResponder];
  return YES;
}

@end

[jessesar]

no, then i keep getting errors

but

textFielsShouldReturn

maybe this should be:

textFieldShouldReturn

?

[bikr]

yah, typo on my part.. should be as you typed.

[jessesar]

that don't work also

[bikr]

ok , well that's how you do it directly form the documentation copy and pasted.. So.. problem must lie elsewhere.. did you create the outlets and declare them in your .h?

[jessesar]

this is lockerViewController.h:

#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>

@interface lockerViewController : UIViewController {
    IBOutlet UITextField *codeField;
}
- (IBAction)lock;
@end

and this is lockerViewController.m:

#import "lockerViewController.h"

@implementation lockerViewController
- (IBAction)lock {
    
}

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
	[textField] resignFirstResponder];
	return YES;
}

@end

[bikr]

I'm pretty sure you want it in the view class not the controller but you got me

Yes, same problem for me. It works when implemented in the view class, but I need it to execute a method from the controller. Please someone with an idea?

To hide a keyboard u need just to setup a callback (i.e. IBAction) for the event "Did End On Exit" of UITextField in the InterfaceBuilder. So make ur UITextField an IBOutlet and put an empty IBAction as a callback for "Did End On Exit". That's all.

Like this:

//header

@interface MyView : UIView
{
IBOutlet UITextField *name;
}

- (IBAction)doneButtonOnKeyboardPressed: (id)sender;

//m-file

@implementation MyView

- (IBAction)doneButtonOnKeyboardPressed: (id)sender
{}

@end

Can Somebody tell me how to dismiss keyboard on click of UITextField which i created in interface builder because i want to select data from the UIPickerView to fill the UITextField instead of typing the text from the keyboard

There is an attribute editable for text field which can be set through attribute inspector

deselect this attribute

this will make sure that text inside text field can not be modified by user.

hence key board will not appear.............

happy coding

Hi nikvpat,

I have created UIPickerView using interface builder and i want to load this when the user clicks on UITextField, every time i click on UiTextField Keyboard pops up but i dont see UIPickerView loading from NSBundle can help me on this

Thanks in advance

I simply point the Did End On Exit to a dummy piece of code.

Dismisses the keyboard just fine.

Refer methods of text field delegate in Apple Doc.....

find out method which causes keyboard to pop up.

in that method you can load UIPickerView from NIB file.

happy coding...............

I try to repeat example into First Steps manual, but i can't understand how to hide keyboard when you press the button Done.
here is my code in "MyViewController.h"

#import <UIKit/UIKit.h>


@interface MyViewController : UIViewController {
UITextField *textField;
UILabel *label;
NSString *string;
}

@property (nonatomic, retain) IBOutlet UITextField *textField;
@property (nonatomic, retain) IBOutlet UILabel *label;
@property (nonatomic, copy) NSString *string;
- (IBAction)changeGreeting:(id)sender;
@end

and "MyViewController.m"

#import "MyViewController.h"

@implementation MyViewController
@synthesize textField;
@synthesize label;
@synthesize string;
- (IBAction)changeGreeting:(id)sender {
self.string = textField.text;
NSString *nameString = string;
if ([nameString length] == 0) {
nameString = @"World";
}
NSString *greeting = [[NSString alloc] initWithFormat:@"Hello, %@!",nameString];
label.text = greeting;

[greeting release];
}

-(BOOL)textFieldShouldReturn:(UITextField *)Done {
[Done resignFirstResponder];
return YES;
}

where is mistake ? keyboard doesn't hide.

[Malork]

make these changes in your .H-file:

#import <UIKit/UIKit.h>


@interface MyViewController : UIViewController {
UITextField *textField;
UILabel *label;
NSString *string;
}

@property (nonatomic, retain) IBOutlet UITextField *textField;
@property (nonatomic, retain) IBOutlet UILabel *label;
@property (nonatomic, copy) NSString *string;
- (IBAction)changeGreeting: (id)sender;
- (IBAction)dismissKeyboard: (id)sender;

@end

and in your .m-file:

#import "MyViewController.h"

@implementation MyViewController
@synthesize textField;
@synthesize label;
@synthesize string;
- (IBAction)changeGreeting: (id)sender {
self.string = textField.text;
NSString *nameString = string;
if ([nameString length] == 0) {
nameString = @"World";
}
NSString *greeting = [[NSString alloc] initWithFormat:@"Hello, %@!",nameString];
label.text = greeting;

[greeting release];
}

-(IBAction)dismissKeyboard: (id)sender {
[sender resignFirstResponder];
}

then, connect in the IB's inspector for the textfield the 'did end on exit' option and connect it to the 'dismissKeyboard'.

Also, I believe it's also possible to do it with a delegate so you do not need to connect anything, but I'm not sure and have to look that one up.
(I think it had something to do with the <UIApplicationDelegate> protocol....)
But don't take my word for that one....yet..

[Jeremy1026]

To use the code initially posted you have to make the textfield delegate self for the textfield that is currently the first responder..
