输入框的AccessoryInputView

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];

}
