推荐答案

加载html时，将发布通知. 您可以使用以下代码收听它:

When the html is loaded, a notification is posted. You can listen to it with this code:

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(pageDidLoad) name:CDVPageDidLoadNotification object:self.webView];

然后，在收到通知时，将调用pageDidLoad方法，将您的代码放在此处

Then, when the notification is received, the pageDidLoad method will be called, put your code there

- (void)pageDidLoad
{
    NSString * jscode = @"some js code here";
   [self.viewView stringByEvaluatingJavaScriptFromString: jscode];
}
