很神奇的问题求大神

今天发现一个很神奇的BUG，就是iPad10.3.3的系统下，当网页上有select控件的时候，添加自定义键盘，点击select就会崩溃，有啥办法解决？这里放上源码
ViewController.m
- (void)viewDidLoad {
    [super viewDidLoad];
    UIWebView *webView = [[UIWebView alloc] initWithFrame:self.view.bounds];
    webView.delegate = self;
    [self.view addSubview:webView];
    
    NSString *filePath = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"html"];
    NSURL *url = [[NSURL alloc] initWithString:filePath];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    [webView loadRequest:request];
    
    [self.view addSubview:[CIBSafeKeyboardTextField sharedTextField]];
}- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
    
    NSString *absolutePath = request.URL.absoluteString;
    
    NSString *scheme = @"rrcc://";
    
    if ([absolutePath hasPrefix:scheme]) {
        NSString *subPath = [absolutePath substringFromIndex:scheme.length];
        NSString *methodName = [subPath stringByReplacingOccurrencesOfString:@"_" withString:@":"];
        SEL sel = NSSelectorFromString(methodName);
        
        if ([self respondsToSelector:sel]) {
            [self performSelector:sel];
            return NO;
        }
    }    return YES;
}- (void)shareToTest {
    [[CIBSafeKeyboardTextField sharedTextField] becomeFirstResponder];
}CIBSafeKeyboardTextField.h@interface CIBSafeKeyboardTextField : UITextField+ (CIBSafeKeyboardTextField *)sharedTextField;@endCIBSafeKeyboardTextField.m@implementation CIBSafeKeyboardTextField+ (CIBSafeKeyboardTextField *)sharedTextField {
    static CIBSafeKeyboardTextField *_textField = nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        _textField = [[self alloc] init];
    });
    return _textField;
}- (instancetype)init
{
    self = [super init];
    if (self) {
        
        self.inputView = [[UIView alloc] init];
    }
    return self;
