In my iPad app, I noticed different behavior between iOS 6 and iOS 7 with UITextFields.
I create the UITextField as follows:
UIButton *theButton = (UIButton*)sender;
UITextField *textField = [[UITextField alloc] initWithFrame:[theButton frame]];
[textField setDelegate:self];
[textField setContentVerticalAlignment:UIControlContentVerticalAlignmentCenter];
[textField setContentHorizontalAlignment:UIControlContentHorizontalAlignmentRight];
textField.textAlignment = UITextAlignmentRight;
textField.keyboardType = UIKeyboardTypeDefault;
...
[textField becomeFirstResponder];
In iOS 6, when I type "hello world" the cursor advances a blank space when I hit the spacebar after "hello."
In iOS 7, the cursor does not advance when I hit the spacebar. However, when I type the "w" in "world," it shows the space and the w.
How can I advance the cursor when the spacebar is hit in iOS 7?
Update:
If I change the textField.textAlignment to UITextAlignmentLeft, then the space appears in iOS 7. I would like to keep it right aligned, if possible.
It would be a bit of a hack, but if you really need that to look the iOS6 way, you can replace space with non-breaking space as it's written. It's treated differently. Example code could look like this:
- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
// only when adding on the end of textfield && it's a space
if (range.location == textField.text.length && [string isEqualToString:@" "]) {
// ignore replacement string and add your own
textField.text = [textField.text stringByAppendingString:@"\u00a0"];
return NO;
}
// for all other cases, proceed with replacement
return YES;
}
In case it's not clear, textField:shouldChangeCharactersInRange:replacementString:
is a UITextFieldDelegate
protocol method, so in your example, the above method would be in the viewcontroller designated by [textField setDelegate:self]
.
If you want your regular spaces back, you will obviously also need to remember to convert the text back by replacing occurrences of @"\u00a0"
with @" "
when getting the string out of the textfield.
