Ios 自定义键盘，将文本输入到UITextField

我很难实现一个键盘附件，当按下附件上的键时，它会将文本输入UITextField。这是一个大致的草图，看起来像：

最终，我希望当用户点击“@gmail”按钮时，它可以输入当前的电子邮件地址UITextField@gmail.com，这样用户就不必输入了。我遇到了一些问题，因为我正在以编程方式编写keyboardaccessoryview，我无法确定是否要将keyboardaccess中的keyinput转到电子邮件地址的UITextField。我试过用这个做一个IBAction

NSString *appendThisText = @"@gmail.com";
self.textFieldOne.text=[NSString stringWithFormat:@"%@%@", self.textFieldOne.text, appendThisText];

但那没用。我需要帮助。这是我的登录查看控制器.h的代码

#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;
}

- (IBAction)dismiss:(id)sender;

- (IBAction)toggleUIButtonImage:(id)sender;

- (IBAction)backgroundTouched:(id)sender;
