UitextField resignFirstResponder does not work in scroll view
I have 2 functions to resignFirstResponder but neither of them works when the textfields are in scrollview
my functions:
-(BOOL)textFieldShouldReturn:(UITextField *)theTextField {
if (theTextField == textField1) {
[textField1 resignFirstResponder];
}
if (theTextField == textField2) {
[textField2 resignFirstResponder];
}
if (theTextField == textField3) {
[textField3 resignFirstResponder];
}
return YES;
}
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [[event allTouches] anyObject];
[textField1 resignFirstResponder];
[textField2 resignFirstResponder];
[textField3 resignFirstResponder];
}
I have linked the scrol开发者_StackOverflowl view in IB, I can not find out why it does not works there only when I click outside of scrollview.so it only responds to view, but why?I thougth that [[event allTouches] anyObject]
respond to ALLtouches at ANYObjects
Thanks for help
You can also use a gesture recognizer to get the background tap. Use cancelsTouchesInView = NO to forward all other touches to the right receivers.
UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(didTappedBackground:)];
tapGesture.cancelsTouchesInView = NO;
[self.scrollView addGestureRecognizer:tapGesture];
Wouldn't it be a bit more elegant to add a transparent view that inherits UIControl
with the size that equal to your scroll view to the very back of it and then just create IBAction
for this new view?
@interface ScrollView <UIScrollViewDelegate,UITextFieldDelegate> {
UITextField *_currentTF;
}
@implementation
- (void)viewDidLoad {
yourScrollView.delegate = self;
yourTextField.delegate = self;
}
#pragma mark UIScrollViewDelegate
- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView {
[_currentTF resignFirstResponder];
}
#pragma mark UITextFieldDelegate
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
_currentTF = textField;
return YES;
}
