UITextView自定义键盘和系统键盘

UITextView有inputView 和 inputAccessoryView 两个属性，都指定了相应的视图， inputAccessoryView 对象显示在 inputView 对象的上面。与输入相关的还有一个 reloadInputViews 方法用来重新载入输入视图。如图：


代码：

if (bt.selected == YES) {
bt.selected = NO;
[m_textView setInputView:nil];
[m_textView becomeFirstResponder];
}else if(bt.selected == NO){
addEmojiImgView = [AddEmojiImgView initEmojiImgView];
[m_textView setInputView:addEmojiImgView];
bt.selected = YES;
[m_textView becomeFirstResponder];
}
[m_textView reloadInputViews];
