在ios中使用自定义键盘的问题

我已经从this下载了一个使用自定义键盘的示例项目。在ios中使用自定义键盘的问题

它完美的作品。

但是，当我用在我的项目则返回错误 - -[UIView playKeyboardClick]: unrecognized selector sent to instance 0x71d6390

了什么我做了 -

我增添了新的viewcontoller文件NerdKeyboard.h和NerdKeyboard.m和UIView文件NerdKeyboardView.h和NerdKeyboardView.m。我粘贴了来自示例项目的相同编码，并在xib中执行相同的设计。

但是当我点击NerdKeyboard.xib按钮文件，它会返回一个错误

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIView playKeyboardClick]: unrecognized selector sent to instance 0x71d6390' *** First throw call stack: (0x1c92012 0x10cfe7e 0x1d1d4bd 0x1c81bbc 0x1c8194e 0x2769 0x10e3705 0x172c0 0x17258 0xd8021 0xd857f 0xd76e8 0x46cef 0x46f02 0x24d4a 0x16698 0x1beddf9 0x1bedad0 0x1c07bf5 0x1c07962 0x1c38bb6 0x1c37f44 0x1c37e1b 0x1bec7e3 0x1bec668 0x13ffc 0x1ebd 0x1de5) libc++abi.dylib: terminate called throwing an exception

如果你想看到的代码：

NerdKeyboard.h

#import <UIKit/UIKit.h> 

@interface NerdKeyboard : UIViewController 

@property (nonatomic, weak) id delegate; 

- (IBAction)keyPress:(id)sender; 
- (IBAction)doneEditing:(id)sender; 

@end

NerdKeyboard.m

#import "NerdKeyboard.h" 
#import "NerdKeyboardView.h" 

@implementation NerdKeyboard 

- (IBAction)keyPress:(id)sender 
{ 
    [(NerdKeyboardView *)self.view playKeyboardClick]; 

    if (self.delegate && [self.delegate respondsToSelector:@selector(setText:)]) { 
     NSString *oldText = [self.delegate text]; 
     NSString *thisKey = [[(UIButton *)sender titleLabel] text]; 

     [self.delegate performSelector:@selector(setText:) withObject:[oldText stringByAppendingString:thisKey]]; 
    } else if (self.delegate && [self.delegate respondsToSelector:@selector(nerdKeyPress:)]) { 
     [self.delegate performSelector:@selector(nerdKeyPress:) withObject:[[(UIButton *)sender titleLabel] text]]; 
    } 
} 

- (IBAction)doneEditing:(id)sender 
{ 
    if (self.delegate && [self.delegate respondsToSelector:@selector(resignFirstResponder)]) { 
     [self.delegate performSelector:@selector(resignFirstResponder)]; 
    } 
} 

@end

NerdKeyboardView.h

#import <UIKit/UIKit.h> 

@interface NerdKeyboardView : UIView <UIInputViewAudioFeedback> 

- (void)playKeyboardClick; 

@end

NerdKeyboardView.m

#import "NerdKeyboardView.h" 

@implementation NerdKeyboardView 

- (BOOL)enableInputClicksWhenVisible { 
    return YES; 
} 

- (void)playKeyboardClick 
{ 
    [[UIDevice currentDevice] playInputClick]; 
} 

@end

当我调试它的错误是在该行[(NerdKeyboardView *)self.view playKeyboardClick];

什么马抛出问题是什么？

任何建议，将不胜感激。

它看起来像你的视图控制器的视图是一个普通的'UIView'而不是'NerdKeyboardView'。确保你在xib中正确设置了类。 – omz

如果连接不正确或操作系统无法找到定义的功能，则会出现此类错误。如果您使用的是xib，请检查连接是否正确。否则请检查功能setText是书面正确。可能会有一个问题与外壳或功能的名称。

连接没有问题，当我调试它的错误抛出谎言'[（NerdKeyboardView *）self.view playKeyboardClick];' – NAZIK

+1的建议 – NAZIK

在playkeyboardclick方法中放置一个断点，并调试，看看是否控制正在进入它..其他有一些问题与self.view..maybe它为零 –
