Dismiss TextView or TextField | Chinese Rule of Eight

1) When clicking ‘Done’

Put protocol UITextViewDelegate and/or UITextFieldDelegate in there…

@interface RegistrationViewController : UIViewController

UITextViewDelegate, UITextFieldDelegate

set up the variable….make sure you add target for the method UIControlEventEditingDidEndOnExit:

//insert uitextfield

UITextField * nameTextField = [[UITextField alloc] initWithFrame:CGRectMake(10.0f, 128.0f, 300.0f, 64.0f)];

nameTextField.tag = UITEXTFIELD_NAME;

[nameTextField setText:@"test"];

nameTextField.borderStyle = UITextBorderStyleRoundedRect;

nameTextField.textColor = [UIColor blackColor];

nameTextField.delegate = self;

[nameTextField addTarget:self action:@selector(textFieldDoneEditing:) forControlEvents:UIControlEventEditingDidEndOnExit ];

nameTextField.font = [UIFont systemFontOfSize:20.0 ];

nameTextField.autocorrectionType = UITextAutocorrectionTypeNo;

nameTextField.keyboardType = UIKeyboardTypeDefault;

nameTextField.returnKeyType = UIReturnKeyDone;

nameTextField.clearButtonMode = UITextFieldViewModeWhileEditing;

[self.view addSubview:nameTextField];

[nameTextField release];

Implement the method:

#pragma mark - responds to Done button pushed on keyboard

- (BOOL)textFieldDoneEditing:(UITextField *)textField

{

DLOG(@"textFieldDoneEditing");

[textField resignFirstResponder];

return YES;

}

view controller’s header:

1	@property (nonatomic, assign) id currentResponder;

view controller’s viewDidLoad:

//add tap gesture recognizer for our self.view

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(resignOnTap:)];

[singleTap setNumberOfTapsRequired:1];

[singleTap setNumberOfTouchesRequired:1];

[self.view addGestureRecognizer:singleTap];

[singleTap release];

view controller:

//our responder takes on whatever textfield is being edited

- (void)textFieldDidBeginEditing:(UITextField *)textField {

DLOG(@"textFieldDidBeginEditing");

self.currentResponder = textField;

}
