Some keyboard types does not have buttons correspondent for keyReturnType such as Next, Done. It is observable on IPhone for numeric keyboard types. That prevents traversing forms with "number" input fields and impacts end-user experience. The improvement allows application for adding extra buttons via inputAccessoryView. Because RCTText is not a project exposed to React application calling all methods to add a handler is done using selectors. Here is a code fragment which has an example on how to achieve it: Within application: facebook#1 Create a keyboard Handle KeyboardAccessory keyboardHandler = ^UIView *(UITextField *textField) { ReactTextAdapter *kAdapter = [[ReactTextAdapter alloc] init:textField]; return [kAdapter getInputAccessory]; }; 2. Register an adapter Class clz = NSClassFromString(@"RCTTextField"); SEL selector = NSSelectorFromString(@"registerForKeyboardType:handler:"); if ([clz respondsToSelector:selector]) { [ clz performSelector:selector withObject:[NSNumber numberWithInt:UIKeyboardTypeNumberPad] withObject:keyboardHandler]; } facebook#3 Example of Keyboard Adapter @interface ReactTextAdapter :UIToolbar -(instancetype) init:(UITextField *)textField; -(UIView *)getInputAccessory; @EnD // // ReactTextAdapter.m // KeyboardTest // // Created by Krivopaltsev, Eugene on 3/11/16. // #import "ReactTextAdapter.h" @interface ReactTextAdapter() @Property (nonatomic) UITextField *textField; //@Property (nonatomic)UIToolbar *toolBar; @Property (nonatomic)UIBarButtonItem *flexible; @EnD @implementation ReactTextAdapter -(instancetype) init:(UITextField *)textField { self = [super init]; if (self) { self.textField = textField; [self setBarStyle:UIBarStyleDefault]; self.translatesAutoresizingMaskIntoConstraints = NO; self.flexible = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil]; // since there is a next field, add a NEXT button to the picker if (self. textField. returnKeyType == UIReturnKeyNext) { NSString *nextText = @"Next"; UIBarButtonItem *nextButton = [[UIBarButtonItem alloc] initWithTitle:nextText style:UIBarButtonItemStyleDone target:self action:@selector(next)]; self.items = [[NSArray alloc] initWithObjects: self.flexible, nextButton, nil]; }else if (self.textField. returnKeyType == UIReturnKeyContinue) { NSString *continueText = @"Continue"; UIBarButtonItem *contButton = [[UIBarButtonItem alloc] initWithTitle:continueText style:UIBarButtonItemStyleDone target:self action:@selector(next)]; self.items = [[NSArray alloc] initWithObjects: self.flexible, contButton, nil]; } else if (self. textField.returnKeyType == UIReturnKeyDone) { NSString *doneText = @"Done"; UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithTitle:doneText style:UIBarButtonItemStyleDone target:self action:@selector(done)]; doneButton.enabled = YES; self.items = [[NSArray alloc] initWithObjects: self.flexible, doneButton, nil]; } } return self; } -(void) done { [self passToReactNative]; [self.textField resignFirstResponder]; } -(void) next { [self passToReactNative]; } -(void) passToReactNative { SEL selector = @selector(textFieldSubmitEditing); if ([self.textField respondsToSelector:selector]) { [self.textField performSelector:selector withObject:nil]; } } -(UIView *)getInputAccessory { return self; }
