问题：键盘上的AccessoryInputView是一个输入框；
1. 创建子视图
-(void)addSubviews {
UITextField*textField = [UITextFieldnew];
[textFieldbecomeFirstResponder];
[selfaddSubview:textField];
self.textView= [[UITextViewalloc]initWithFrame:CGRectMake(20,100,280,60)];
self.textView.backgroundColor= [UIColorredColor];
[self.textViewbecomeFirstResponder];
textField.inputAccessoryView=self.textView;
}
2. 显示视图
-(void)show {
[[UIApplicationsharedApplication].keyWindowaddSubview:self];
}
3. 干掉视图
-(void)dismiss {
[[UIApplicationsharedApplication].keyWindowendEditing:YES];
//[[UIApplication sharedApplication] sendAction:@selector(resignFirstResponder) to:nil from:nil forEvent:nil];
[selfremoveFromSuperview];
}
