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;



@end

CIBSafeKeyboardTextField.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;

}



@end
