}
}
how to disable the table when we click on view.i am having three tableviews?
Try this
ViewDidLoad

[self.view addGestureRecognizer:tap];
ActionMethod
- (void) handelGesture:(UITapGestureRecognizer*)sender
{
myTableview.hidden = YES;
}
Hope this helps.
Please check this code it working if you modified for your requirement Thanks
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
NSArray *subviews = [self.view subviews];
for (id objects in subviews) {
if ([objects isKindOfClass:[UITextField class]]) {
UITextField *theTextField = objects;
if ([objects isFirstResponder]) {
[theTextField resignFirstResponder];
}

iOS - Dismiss keyboard when touching outside of UITextField
(38 answers)
Closed 6 years ago.
I am using this method but keyboard isn't hiding.
-(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{
[_myTextView resignFirstResponder];
}
How can I dismiss the keyboard on simply touching outside the keyboard. Would be great if the solution is for both objective c and swift. Thanks
I have a query in objective C for textView inside scrollView. Please resolve. I've searched but have found no discrete solution.
try this
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
[self.view endEditing:YES];
[self.yourScrollviewName endEditing:YES];
}
or use like
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [[event allTouches] anyObject];
if (![[touch view] isKindOfClass:[UITextView class]]) {
[self.view endEditing:YES];
[self.yourScrollviewName endEditing:YES];
}
[super touchesBegan:touches withEvent:event];
}
the above code not work try this
- (void)viewDidLoad
{
[super viewDidLoad];
UITapGestureRecognizer *resignView = [[UITapGestureRecognizer alloc]
initWithTarget:self action:#selector(handleSingleTapforResign:)];
resignView.cancelsTouchesInView = NO;
[self.view addGestureRecognizer: resignView];
}
Dismiss what ever is currently editing:
- (void) handleSingleTapforResign:(UITapGestureRecognizer *) sender
{
[self.view endEditing:YES];
[self.yourScrollviewName endEditing:YES];
}
Hi I have some buttons that trigger action methods.
In addition, I would like the user to be able to swipe left or right over the area with the buttons to show some different buttons
My idea was to add a UIView with a clear background color on top of the buttons so that the user could still see the buttons but could also swipe to the right or left.
However, when the view is over the buttons the buttons no longer work and when it is under the buttons, the swipe is not detected.
In addition to changing the view color to clear, I also tried adjusting the alpha however this seems to work the same way. When alpha of the UIView is zero, swipes are no longer detected and when alpha is greater than zero, the buttons no longer work.
Can anyone suggest a way to do this?
Thanks in advance for any suggestions.
Code I am using for buttons and to detect swipes seems standard. Trying to figure out a way to expose view and buttons at the same time.
Action methods to which buttons are wired:
//.h file
- (IBAction)showIncoming:(id)sender;
- (IBAction)showOutcoming:(id)sender;
/.m file
- (IBAction)showIncoming:(id)sender {
_showIncoming=YES;
_fetchedResultsController=nil;
[self.tableView reloadData];
[self updateInterface];
}
- (IBAction)showOutgoing:(id)sender {
_showIncoming=NO;
_fetchedResultsController=nil;
[self.tableView reloadData];
[self updateInterface];
}
Swipes:
//in viewWillAppear
UISwipeGestureRecognizer *rightRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(rightSwipeHandle:)];
rightRecognizer.direction = UISwipeGestureRecognizerDirectionRight;
[rightRecognizer setNumberOfTouchesRequired:1];
rightRecognizer.delegate = self;
[_topView addGestureRecognizer:rightRecognizer];
[_topView setUserInteractionEnabled:YES];
// [rightRecognizer release];
//........towards left Gesture recogniser for swiping.....//
UISwipeGestureRecognizer *leftRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(leftSwipeHandle:)];
leftRecognizer.direction = UISwipeGestureRecognizerDirectionLeft;
[leftRecognizer setNumberOfTouchesRequired:1];
leftRecognizer.delegate = self;
[_topView addGestureRecognizer:leftRecognizer];
[_topView setUserInteractionEnabled:YES];
}
- (void)rightSwipeHandle:(UISwipeGestureRecognizer*)gestureRecognizer
{
//Do moving
NSLog(#"Right Swipe performed");
_showOld=YES;
[self updateInterface];
}
- (void)leftSwipeHandle:(UISwipeGestureRecognizer*)gestureRecognizer
{
// do moving
NSLog(#"Left Swipe performed");
_showOld=NO;
[self updateInterface];
}
The approach I suggest is listening to a user moving a finger events and firing specified method that would check if user's finger is on your button's view. Sample code:
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
[self touchedViewWithTouches:touches andEvent:event];
}
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
[self touchedViewWithTouches:touches andEvent:event];
}
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
[self touchedViewWithTouches:touches andEvent:event];
}
- (void)didTouchedButton:(NSSet *)touches andEvent:(UIEvent *)event {
UITouch *touch = [[event allTouches] anyObject];
CGPoint touchLocation = [touch locationInView:touch.view];
UIView *touchedView;
for (UIView *view in self.subviews) {
if(CGRectContainsPoint(view.frame, touchLocation)) {
touchedView = view;
break;
}
}
if (view == self.showIncomingButton) {
[self showIncoming:self.showIncomingButton];
} else if (view == self.showOutcomingButton) {
[self howOutcoming:self.showOutcomingButton];
}
}
Note that you will have to add two outlets for your buttons (if you don't have any). Also, you can get rid off (id)sender in your IBAction calls.
Hello I'm trying to have two of my UITextFields' keyboards hide when the user clicks off of the keyboard. I need both of my textfields to have the same method. How can I do this without duplicating them and giving Xcode and error?
Thanks!
Here's the method I'm using for my first textfield I need the same for my other.
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [[event allTouches] anyObject];
if ([text1 isFirstResponder] && [touch view] != text1) {
[text1 resignFirstResponder];
}
[super touchesBegan:touches withEvent:event];
}
Apple strongly recommends to use gesture recognizers, not touchesBegan and other "touches" methods if you do not really have to use them.
Try this code. It will work for any numbers of text views inside view controller.
- (void)viewDidLoad
{
[super viewDidLoad];
UIGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(onBackgroundTapped)];
[self.view addGestureRecognizer:tapRecognizer];
... another initialization code
}
- (void)onBackgroundTapped
{
[self.view endEditing:YES];
}

Dismiss keyboard on touch anywhere outside UITextField
I am using UIScrollView in my app. I am putting few text fields and button. I want to hide my keyboard when they touch outside of the textbox. (I mean they will be taping on the uiscrollview). I have tried a lot of things... I use UIGestureRecognizer but its not working... help please
Here's the solution just tried and it works.. Hope helps
Add the following code to your viewDidLoad;
-(void)viewDidLoad {
//create a tapGesture which calls a removeKeyboard method
UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(removeKeyboard)];
tapGesture.cancelsTouchesInView = NO;
[self.yourScrollView addGestureRecognizer:tapGesture];
}
-(void)removeKeyboard {
[self.yourTextField resignFirstResponder];
}
Hope helps....
Try the following code in your view...
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [[event allTouches] anyObject];
if ([yourTextView isFirstResponder] && [touch view] != yourTextView) {
[yourTextView resignFirstResponder];
}
}
I'm making a tweak that involves popping an alert whenever the user double taps an icon in editing mode. I've tried hooking on to
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
of SBIcon and then
{
%orig;
UITouch *touch = [touches anyObject];
if (touch.tapCount == 2 && [[objc_getClass("SBIconController") sharedInstance] isEditing])
{
//pop an alert and do stuff
}
}
But this doesn't seem to work at all. Could anyone tell me what is wrong with the above and suggest alternative ways to achieve this?
EDIT: I'm using theos, if it matters.
I will suggest you to use Tap gesture recognizer.It is more specific and works very accurately.
For more info you can check out this link:
http://developer.apple.com/library/ios/#documentation/EventHandling/Conceptual/EventHandlingiPhoneOS/GestureRecognizers/GestureRecognizers.html
Alternative ways for you
If your icon is a button then you can easily detect the Double tab by adding UIControlEventTouchDownRepeat event
[yourIconButton addTarget:self action:#selector(multipleTap:withEvent:)
forControlEvents:UIControlEventTouchDownRepeat];
-(IBAction)multipleTap:(id)sender withEvent:(UIEvent*)event
{
UITouch* touch = [[event allTouches] anyObject];
if (touch.tapCount == 2) {
// Do all your actions here
}
}
If you are considering it for a whole view then use UITapGesture
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(tapAction:)];
[tap setNumberOfTapsRequired:2];
[yourIconView addGestureRecognizer:tap];
- (void)tapAction:(UIGestureRecognizer *)gestureRecognizer
{
//Do your action
}
