除非两次调用此代码，否则 iOS UIWebView 标题不会更新 [英] iOS UIWebView title doesn't update unless calling this code twice

问题描述

网页标题不会更新，除非我调用该方法两次

Webpage title doesn't update unless I call the method twice

NSURL *yourURL = [NSURL URLWithString: webpageURLLabel.text ];
NSURLRequest *request = [[NSURLRequest alloc] initWithURL:yourURL];
[webpagePreview loadRequest:request];
webpagePreview.scalesPageToFit = YES;
webpageTitleLabel.text = [webpagePreview stringByEvaluatingJavaScriptFromString:@"document.title"];

有关如何解决此问题的任何建议?
