我正在创建一个自定义键盘附件视图。我目前已经完成了大约 95% 的工作。我唯一剩下的就是删除原生 iOS 键盘上方的 1px（或 2px？）行。有没有办法给 inputaccessoryview 添加边框，这样我就可以使用与键盘渐变相同的颜色来消除黑条？

图片示例

如果寄宿生是不可能的，那么与我的源代码有关的下一个最合乎逻辑的事情是什么？

signInViewController.h

#import <UIKit/UIKit.h>
#import <AVFoundation/AVAudioPlayer.h>
#import <AudioToolbox/AudioToolbox.h>

@interface signInViewController : UIViewController <UITextFieldDelegate, UITextViewDelegate> {
AVAudioPlayer *sound;
UIButton *myButton;
UITextField *textFieldOne;
UIButton *gmailButton;
UIButton *meButton;
UIButton *yahooButton;
UIButton *outlookButton;
UIView *inputAccView;
UIButton *aolButton;
UIButton *milButton;
}


- (IBAction)playSwoosh:(id)sender;

- (IBAction)dismiss:(id)sender;

- (IBAction)toggleUIButtonImage:(id)sender;

- (IBAction)backgroundTouched:(id)sender;



@property (weak, nonatomic) IBOutlet UITextField *textFieldOne;
@property (weak, nonatomic) IBOutlet UITextField *textFieldTwo;
@property (nonatomic, retain) UIButton *gmailButton;
@property (nonatomic, retain) UIButton *meButton;
@property (nonatomic, retain) UIButton *yahooButton;

好吧，在玩过它之后，我决定不添加寄宿生，因为它所做的只是包括了一个内部寄宿生。我只是简单地画了一个物体来掩盖它。但我确实为那些仍然想知道如何做的人找到了一个很好的资源！这是另一种非常适合实施的方法。对于那些只想快速修复的新开发人员，有人确实提议让我简单地创建另一个按钮，该按钮是屏幕的长度和 3 px 的高度来覆盖它，但我们都知道这是错误的答案。只是给任何新手的提示

根据https://github.com/ardaogulcan/react-native-keyboard-accessory上的文档，它KeyboardAccessoryView有一个特殊的属性， 我想它具有相同的属性。hideBorderInputAccessoryView
