From the docs , searchBarTextDidBeginEditing: searchBarCancelButtonClicked: If you are implementing UISearchBarDelegate, the first method that should be called is: - (BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar { //do stuff return YES; } Here's the class reference: http://developer.apple.com/iphone/library/documentation/UIKit/Reference/UISearchBarDelegate_Protocol/Reference/Reference.html#//apple_ref/occ/intfm/UISearchBarDelegate/searchBarShouldBeginEditing : Your searchbar

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

I'm implementing a chat UI, and using Reactive Cocoa to adjust the chat bubble's size as the user types. Currently, I'm updating the UI's layout based on the textview's rac_textSignal . Everything's working great - except for one bit: when the user sends the message, I programmatically clear the textfield: _inputTextView.text = @""; ... but the textview's rac_textSignal doesn't activate. I hear this is a feature with ReactiveCocoa - but what's the proper way to build this? Do I need to have an NSString holding the currentlyTypedString , and drive the UI changes when that string updates? Yep,

I have a UISearchBar on which I am trying to set a cursor position. I am using UITectField delegates as I couldn't find anything direct for UISearchBar. Below is the code I am using: UITextField *textField = [searchBar valueForKey: @"_searchField"]; // Get current selected range , this example assumes is an insertion point or empty selection UITextRange *selectedRange = [textField selectedTextRange]; // Construct a new range using the object that adopts the UITextInput, our textfield UITextRange *newRange = [textField textRangeFromPosition:selectedRange.start toPosition:selectedRange.end];

I know that if we want to auto fetch the OTP(if we use single textfield) we need to use otpTextField.textContentType = .oneTimeCode But, If we use multiple textfield(According to following image) how should we achieve this ? Natarajan If you can get the auto OTP for single field, you can split that text into your four text fields. I believe. You may have to use textField's change observer as like below, textField.addTarget(self, action: #selector(textFieldDidChange(_:)), for: .editingChanged) func textFieldDidChange(_ textField: UITextField) { // here check you text field's input Type if

How do you add a text field to the title view of a navigation item and have it sized correctly? It works fine if I do this with a search bar like this but I don't know how to get a text field to size itself in the same way as a search bar. myViewController.navigationItem.titleView = [UISearchBar new]; As my comment suggested, try the following, which seems to me is what you're after. UITextField *textField = [[UITextField alloc]initWithFrame:CGRectMake(0, 0, self.navigationController.navigationBar.frame.size.width, 21.0)]; self.navigationItem.titleView = textField; [textField
