I use an instance of UITextField in which the text is normally aligned to the right, but switches to left alignment when being edited. This is done by calling setTextAlignment: on the editingDidBegin event. Since the update to iOS 6 this behaves strangely: The text alignment is changed correctly from right to left, but the cursor remains at the far right of the text field until some input is performed.
Does anybody know how to restore the expected behaviour so that the cursor moves as well when the alignment is changed?
To give some context: I use the text field to show a value with a unit. The unit is removed during editing and then displayed again after the user hits enter.
Method called on event editingDidBegin:
- (IBAction)textEditingDidBegin:(UITextField *)sender
{
[sender setTextAlignment:NSTextAlignmentLeft];
[sender setText:[NSString stringWithFormat:#"%.0f", width]];
}
Method called on event editingDidEnd:
- (IBAction)textEditingDidEnd:(id)sender
{
[sender setTextAlignment:UITextAlignmentRight];
[sender setText:[NSString stringWithFormat:#"%.0f m", width]];
}
Try resigning the textView as first responder, then make it first responder right after that.
textView.textAlignment = NSTextAlignmentCenter;
[textView resignFirstResponder];
[textView becomeFirstResponder];
-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
textField.textAlignment = NSTextAlignmentLeft ;
return YES ;
}
Change the textAlignment before editing did begin. The best place I know to do this is in the UITextFieldDelegate method textFieldShouldBeginEditing.

I am trying to clear a text field using this action:
emailField.sendKeys("gmail.com");
emailField.sendKeys(Keys.CONTROL,"a",Keys.DELETE);
In above code, the last line only selects the text, does not delete it, but if I separate the actions it works.
emailField.sendKeys(Keys.CONTROL,"a");
emailField.sendKeys(Keys.DELETE);
From the JavaDoc for WebElement.clear():
If this element is a text entry element, this will clear the value.
Has no effect on other elements. Text entry elements are INPUT and
TEXTAREA elements. Note that the events fired by this event may not be
as you'd expect. In particular, we don't fire any keyboard or mouse
events. If you want to ensure keyboard events are fired, consider
using something like sendKeys(CharSequence) with the backspace key. To
ensure you get a change event, consider following with a call to
sendKeys(CharSequence) with the tab key.
Most likely you simply need to call:
emailField.sendKeys("gmail.com");
emailField.clear();
But if you need the clearing to be done via the keyboard for some reason, use Keys.BACKSPACE.
keys.DELETE can not work to delete the input text,you should use keys.BACKSPACE.
emailField.sendKeys(Keys.BACKSPACE)
From the JavaDoc for Keys.chord
chord(java.lang.CharSequence... value)
Simulate pressing many keys at once in a "chord".
You should be able to use
emailField.sendKeys(Keys.chord(Keys.CONTROL,"a",Keys.DELETE));
Tested in chrome driver
WE.send_keys(' \b')
This will add space then delete it (backspace)
I use in javascript and it's working fine:
await textBox.sendKeys(value);
await textBox.sendKeys(Key.BACK_SPACE);
emailField.sendKeys(Keys.BACKSPACE)
doesn't worked for me .
I used 'Key' instead of 'Keys'
emailField.sendKeys(protractor.Key.BACKSPACE)
emailField.sendKeys(Keys.CONTROL + "a",Keys.DELETE);
In PHP:
if you use php-webdriver (https://github.com/php-webdriver/php-webdriver) you must:
use Facebook\WebDriver\WebDriverKeys AS Keys;
.
.
.
$this->driver->findElement(By::id('demo'))->sendKeys([Keys::BACKSPACE,'Any other text']);
Just adding another working C# example using the Google Chrome webdriver.
SendKeys only takes one parameter so created a string with the Crtl + A. This code sequence will select the current text in the field then delete the text.
Code example:
var crtlA = Keys.Control + "a";
driver.FindElement(By.XPath("//div[3]/div[1]/div[2]/div/div[2]/div[2]/div/div/div[1]/div/span/input")).SendKeys(crtlA); Wait(5000); // Select current text
driver.FindElement(By.XPath("//div[3]/div[1]/div[2]/div/div[2]/div[2]/div/div/div[1]/div/span/input")).SendKeys(Keys.Delete); Wait(5000); // Clear current text
driver.FindElement(By.XPath("//div[3]/div[1]/div[2]/div/div[2]/div[2]/div/div/div[1]/div/span/input")).SendKeys(newItemSku); Wait(5000); // Input SKU name
1. in WebdriverIO, i tried to edit the text by clear text (which contains special charactes like #, +, _) in text field by below following step. Eventhough it was not successful.
example: text=> abc+1234#gmail.com
step1:browser.clearElement(selector);
step2:browser.execute(function () {
document.querySelector(>>>Cssselector<<<).value="";
});
step3: browser.doubleClick(selector);
browser.keys("Delete");
step4: browser.click(selector);
browser.keys(['Meta',a]);
browser.keys('Meta');
browser.keys('Delete');
Note: below step is resolved this issue.
var count= browser.getAttribute(selector, value).length;
for (var i=0;i<count;i++)
{
if (browser.getAttribute(selector, value)=='')
break;
}
else
{
browser.doubleClick(selector);
browser.keys("Delete");
}
browser.pause(200);
// it will clear your text field easily.
Note:
You can add the new text now.
You can set the autocapitalizationType property of a UITextField so all input is in upper case. I find that does work fine on the simulator (when actually tapping the simulator's keypad, not the Mac's keyboard), but not on the device? Everything stays lowercase.
In the UICatalog demo I added to the textFieldNormal method:
textFieldNormal.autocapitalizationType = UITextAutocapitalizationTypeAllCharacters;
Added a delegate too, to display the actual autocapitalizationType for the UITextField:
- (void)textFieldDidBeginEditing:(UITextField *)textField
{
NSLog( #"textField.autocapitalizationType=%d", textField.autocapitalizationType );
}
It will properly display 3 (=UITextAutocapitalizationTypeAllCharacters), but anything you tap remains lowercase. What am I missing?
Apparently this is a device general settings issue: Settings -> General -> Keyboard -> Auto-Capitalization must be ON to honour the setting of textField.autocapitalizationType to all upper case, else setting the property is ignored, apparently. If I switch it on everything works as expected.
You could try something like this the the textfield delegate:
-(BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
if (range.length == 0) { // not deleting , but adding a char
textField.text = [textField.text stringByAppendingString:[string uppercaseString]];
return NO;
}
return YES;
}
This works only if you try to insert a symbol at the end of the text.
Should you want to play with the text in the middle you could play with
range.location
and also you will need to play with the cursor positioning as it will go at the end every time...
I hope this helps someone.
This question already has answers here:
UIRefreshControl - beginRefreshing not working when UITableViewController is inside UINavigationController
(15 answers)
Closed 9 years ago.
I am not able to see the loading spinner when calling beginRefreshing
[self.refreshControl beginRefreshing];
My UITableViewController subclass uses a UIRefreshControl
// refresh
UIRefreshControl * refreshControl = [UIRefreshControl new];
[refreshControl addTarget:self action:#selector(refreshTableView) forControlEvents:UIControlEventValueChanged];
self.refreshControl = refreshControl;
It is working perfectly with user interaction (when the user drops the table down), then the spinner is visible.
But when i call beginRefreshing on viewDidLoad, I don't see the spinner (only when i drag the table down).
Notes:
self.refreshControl reference is right
reloadData or endRefreshing is not called immediately after beginRefreshing, but there is a long time delay (loading data through network), so I am not canceling the beginRefreshing.
Edit :
This only happens when the contentOffset property of the tableView is 0 and i call [self.refreshControl beginRefreshing]. Bug? Feauture?
It looks like a bug to me, because it only occures when the contentOffset property of the tableView is 0
I fixed that with the following code (method for the UITableViewController) :
- (void)beginRefreshingTableView {
[self.refreshControl beginRefreshing];
if (self.tableView.contentOffset.y == 0) {
[UIView animateWithDuration:0.25 delay:0 options:UIViewAnimationOptionBeginFromCurrentState animations:^(void){
self.tableView.contentOffset = CGPointMake(0, -self.refreshControl.frame.size.height);
} completion:^(BOOL finished){
}];
}
}
Your fix looks good, But I don't think this as a bug.
When beginRefreshing method is called manually,
When there is no row / cell available it makes sense for refresh control appearing automatically.
But when there are some cells available, and when we call begin refresh manually (A scenario where we refresh periodically based on timer) then It should not animate / change the content offset as it will distract the user if he is seeing / reading content in some visible cell.
I'm building an app where the first view has a menu panel, and I want this panel to stick around for the life of the app. The only places the user can "go" are reachable via buttons on this panel (a UICollectionView). In case it matters, this app is landscape-only, and iOS 6-only.
In order to make this work I created a custom segue, which removes everything from the view except for the menu panel, then adds the new view controller's view as a subview, sets the new view's frame to the bounds of the superview, and sends the new view to the back (so it's behind the menu panel). I call viewWill/DidDisappear from prepareForSegue, because otherwise they don't get called.
It may sound kludgy (it does to me), but it works fine except for one thing - the new view comes up from the bottom. It looks funny.
I then tried adding my own animation block - I initially locate the view off to the left, then animate it into place. I send it to the back in the completion block for the animation. This seems perfectly logical, and the frame values are all what they should be. But this one is worse - the view comes in from the lower left corner.
Can anyone suggest a way to make this work? Here's my current perform method:
- (void)perform {
MainMenuViewController *sourceVC = (MainMenuViewController *)self.sourceViewController;
UIViewController *destinationVC = (UIViewController *)self.destinationViewController;
for (UIView *subview in [sourceVC.mainView subviews]) {
// don't remove the menu panel or the tab
if (![subview isKindOfClass:[UICollectionView class]] && [subview.gestureRecognizers count] == 0) {
[subview removeFromSuperview];
}
}
[sourceVC.mainView addSubview:destinationVC.view];
CGRect finalFrame = sourceVC.mainView.bounds;
CGRect frame = finalFrame;
frame.origin.x = finalFrame.origin.x - finalFrame.size.width;
destinationVC.view.frame = frame;
[UIView animateWithDuration:0.5 animations:^{
destinationVC.view.frame = finalFrame;
} completion:^(BOOL finished) {
// make sure it ends up behind the main menu panel
[sourceVC.mainView sendSubviewToBack:destinationVC.view];
}];
}
It turned out to be a simple error - I needed to set destinationVC's frame before calling addSubview. Setting it afterwards was triggering the unwanted animation.
I want to enter text into a text field and based on the text (if it says "No") I want the alertview to pop up. I've created a UITextField in interface builder and attached it to the UITextField delegate in the files owner so that's all taken care of. But when I enter text into the text field, specifically no, and click out of the textfield or remove the keyboard, no alertview pops up. I have created an entire method for this within the viewcontroller.m file. Here is the code for that method.
-(void)engageAlert {
if (myTextField.text == #"No") {
theAlertView = [[UIAlertView alloc] initWithTitle:#"Notice" message:#"MyMessageHere"
delegate:self cancelButtonTitle:#"Ok" otherButtonTitles:nil, nil];
[theAlertView show];
}
}
Am I missing something here? Nothing happens when I type No into the textfield.
I think the culprit will be the line
myTextField.text == #"No"
Since you're comparing two pointers which will never match.
#"No" = 0x12341234 or whatever address for the static address of the NSString (#"" can be thought of as short hand for the compiler creating the NSString object)
What you will want is something like
if( [myTextField.text isEqualToString:#"No"])
Also check you're not going to leak memory with theAlertView as I can't see where you're freeing that in the snippet.
