#import "AppDelegate.h"

AppDelegate 中添加这段代码，就可以全局不用管键盘的弹起收回了！

#pragma mark - 键盘处理
- (void)completionHandleIQKeyboard
{
 IQKeyboardManager *manager = [IQKeyboardManager sharedManager];
 manager.enable = YES;
 manager.shouldResignOnTouchOutside = YES;
 manager.shouldToolbarUsesTextFieldTintColor = YES;
 manager.enableAutoToolbar = YES;
}

- 1、首先注册通知：
- (void)registNotification
{
 [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWasShown:) name:UIKeyboardWillShowNotification object:nil];
 [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWasHidden:) name:UIKeyboardWillHideNotification object:nil];
}

 

- 2、再把后路想好：移除通知
- (void)removeNotification
{
 [[NSNotificationCenter defaultCenter] removeObserver:self];
}

- 3、通知事件处理：
/*! 键盘显示要做什么 */
- (void)keyboardWasShown:(NSNotification *)notification
{
 NSDictionary *info         = [notification userInfo];

 double duration          = [info[UIKeyboardAnimationDurationUserInfoKey] doubleValue];

 CGFloat curkeyBoardHeight       = [[info objectForKey:@"UIKeyboardBoundsUserInfoKey"] CGRectValue].size.height;
 CGRect begin          = [[info objectForKey:@"UIKeyboardFrameBeginUserInfoKey"] CGRectValue];
 CGRect end           = [[info objectForKey:@"UIKeyboardFrameEndUserInfoKey"] CGRectValue];

 CGFloat keyBoardHeight;

 /*! 第三方键盘回调三次问题，监听仅执行最后一次 */
 if(begin.size.height > 0 && (begin.origin.y - end.origin.y > 0))
 {
  keyBoardHeight         = curkeyBoardHeight;
  [UIView animateWithDuration:duration animations:^{

   CGRect viewFrame       = [self getCurrentViewController].view.frame;
   viewFrame.origin.y -= keyBoardHeight;
   [self getCurrentViewController].view.frame = viewFrame;
  }];
 }
}

- (void)keyboardWasHidden:(NSNotification *)notification
{
 NSDictionary *info = [notification userInfo];
 double duration = [info[UIKeyboardAnimationDurationUserInfoKey] doubleValue];

 [UIView animateWithDuration:duration animations:^{

  CGRect viewFrame = [self getCurrentViewController].view.frame;
  viewFrame.origin.y = 0;
  [self getCurrentViewController].view.frame = viewFrame;
 }];
}

/*!
* 获取当前View的VC
*
* @return 获取当前View的VC
*/
- (UIViewController *)getCurrentViewController
{
 for (UIView *view = self; view; view = view.superview)
 {
 UIResponder *nextResponder = [view nextResponder];
 if ([nextResponder isKindOfClass:[UIViewController class]])
 {
 return (UIViewController *)nextResponder;
 }
 }
 return nil;
}

/*! 第三方键盘回调三次问题，监听仅执行最后一次 */
if(begin.size.height > 0 && (begin.origin.y - end.origin.y > 0))
{
 keyBoardHeight         = curkeyBoardHeight;
 [UIView animateWithDuration:duration animations:^{

  CGRect viewFrame       = [self getCurrentViewController].view.frame;
  viewFrame.origin.y -= keyBoardHeight;
  [self getCurrentViewController].view.frame = viewFrame;
 }];
}

self.replyTextField.inputAccessoryView = self.replyTextField2;

- (void)replyTextFieldChanged:(UITextField *)textField
{
 NSLog(@"textFieldShouldBeginEditing输入内容****：%@", textField.text);
 if (textField != self.replyTextField2)
 {
  self.replyTextField2.text = textField.text;
 }

 NSLog(@"textFieldShouldBeginEditing输入内容1：%@", self.replyTextField.text);
 NSLog(@"textFieldShouldBeginEditing输入内容2：%@", self.replyTextField2.text);
}

- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
 [self.replyTextField resignFirstResponder];
 [self.replyTextField2 resignFirstResponder];

 [[self getCurrentViewController].view endEditing:YES];

 if (self.clickIndexBlock)
 {
  self.clickIndexBlock(self.replyTextField2.text);
  self.replyTextField.text = @"";
  self.replyTextField2.text = @"";
 }

 return YES;
}
