iOS聊天输入框
GYChatMacro.h 宏定义（详细可见：https://github.com/itgyy/GYMacro ）
1、下载-> 进入工程目录-> pod install 2、引入 __weak typeof(self) weakSelf = self; _toolsView = [[GYChatToolsView alloc] init]; [self.view addSubview:_toolsView]; [_toolsView mas_makeConstraints:^(MASConstraintMaker *make) { make.left.right.bottom.equalTo(weakSelf.view); }]; 3、键盘事件 [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillChangeFrame:) name:UIKeyboardWillShowNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidHide:) name:UIKeyboardWillHideNotification object:nil];
-
(void)keyboardWillChangeFrame:(NSNotification *)notification{ CGFloat duration = [notification.userInfo[UIKeyboardAnimationDurationUserInfoKey] floatValue]; CGRect keyboardFrame = [notification.userInfo[UIKeyboardFrameEndUserInfoKey] CGRectValue]; CGFloat transformY = keyboardFrame.origin.y - self.view.frame.size.height; __weak typeof(self) weakSelf = self; [UIView animateWithDuration:duration animations:^{ [_toolsView mas_updateConstraints:^(MASConstraintMaker *make) { make.bottom.equalTo(self.view.mas_bottom).offset(-keyboardFrame.size.height); }]; }]; }
-
(void)keyboardDidHide:(NSNotification *)notification{ __weak typeof(self) weakSelf = self; CGFloat duration = [notification.userInfo[UIKeyboardAnimationDurationUserInfoKey] floatValue]; [UIView animateWithDuration:duration animations:^{ [_toolsView mas_updateConstraints:^(MASConstraintMaker *make) { make.bottom.equalTo(self.view.mas_bottom).offset(0); }]; }]; }
4、输入框取消第一响应
- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{ self.toolsView.isFirstResponse = NO; }
