UIWebView中没有显示键盘？

Question

我使用theos成功编译了这个调整，它在ViewController中显示了UIWebView，但是当我按下webview中的任何文本字段时，我根本无法显示键盘，我做错了什么？

我试过[webView.window makeKeyAndVisible]; [webView canBecomeFirstResponder];方法，但没有运气。

#import <UIKit/UIKit.h>
#import <QuartzCore/QuartzCore.h>

@interface myViewController : UIViewController <UIWebViewDelegate> 
@property (weak, nonatomic) IBOutlet UIWebView *webView; 
@end

%hook myViewController
-(void)viewDidLoad {
    %orig;

        UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 44, 320, 342)];
        [webView setDelegate:self];
        NSString *urlAddress = @"https://www.google.com/";
        NSURL *url = [NSURL URLWithString:urlAddress];
        NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
        [webView loadRequest:requestObj];
        webView.scalesPageToFit=YES;
        webView.backgroundColor = [UIColor clearColor];
        [webView.window makeKeyAndVisible];
        [webView canBecomeFirstResponder];
        [self.view addSubview:webView];

%end
