KeyboardController用于简化iOS的键盘处理。
用法：
To use KeyboardController, simply initialize it with an array of UITextField objects.
id textFields = @[_textField1, _textField2, _textField3, _textField4, _textField5]; self.keyboardController = [KeyboardController controllerWithTextFields:textFields];
KeyboardController, depending on a returnKeyType property of an UITextField instance, will:
UIReturnKeyNext- move to next text fieldUIReturnKeyDone- close keyboard
You can interact with KeyboardController directly via the following methods:
- (void)moveToNextTextField; - (void)moveToPreviousTextField; - (void)closeKeyboard;
KeyboardControllerDelegate
You could also take advantage of delegation methods:
- (void)controllerDidHideKeyboard:(KeyboardController *)controller; - (void)controllerDidShowKeyboard:(KeyboardController *)controller; - (void)controllerWillHideKeyboard:(KeyboardController *)controller; - (void)controllerWillShowKeyboard:(KeyboardController *)controller;
by setting a delegate property of a KeyboardController:
self.keyboardController.delegate = self; UITextFieldDelegate
There is also an option of setting a textFieldDelegate property of all textFields that are under control of KeyboardController:
self.keyboardController.textFieldDelegate = self; This could be particulary useful if you would like to add individual behaviour to UITextFields objects.
- (void)textFieldDidBeginEditing:(UITextField *)textField { if (textField == self.textField4) [self _moveViewByY:-50]; if (textField == self.textField5) [self _moveViewByY:-200]; } - (void)textFieldDidEndEditing:(UITextField *)textField { if (textField == self.textField4) [self _moveViewByY:50]; if (textField == self.textField5) [self _moveViewByY:200]; }
