注意此方法要慎用,因为一旦在一处写过了,在其他所有界面弹出键盘时都会出现此处定义的悬浮窗,不过备忘嘛,此方法还是要贴出来
- (UIView *)inputAccessoryView { UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 50, 30)]; [button setTitle:@"按钮" forState:UIControlStateNormal]; [button addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside]; button.backgroundColor = [UIColor redColor]; UIView *containerView = [UIView new]; containerView.frame = CGRectMake(0, 0, 10, 60); containerView.backgroundColor = [UIColor greenColor]; [containerView addSubview:button]; return containerView; }
