iPad上WKWebView js交互失效

最近公司项目在iPad上所有js交互都失效了，是因为WKWebView 在iPad上加载手机端的网址时，会自动将该网址转为PC端的网址，所以只需改变WKWebview的userAgent浏览器标识就可以了，附上代码:

.h

#import <WebKit/WebKit.h>
@interface BaseWKWebView : WKWebView

@end

.m

#import "BaseWKWebView.h"

@implementation BaseWKWebView

- (instancetype)initWithFrame:(CGRect)frame configuration:(nonnull WKWebViewConfiguration *)configuration
{
    self = [super initWithFrame:frame configuration:configuration];
    if (self) {
        [self evaluateJavaScript:@"navigator.userAgent" completionHandler:^(id __nullable userAgent, NSError * __nullable error) {
            self.customUserAgent = [userAgent stringByReplacingOccurrencesOfString:@"iPad" withString:@"iPhone"];
        }];
    }
    return self;
}
@end

创建WKWebview继承此BaseWKWebView即可
