UIWebView *webView=[[UIWebView alloc] init];
//修改useragent
NSString *useragent = [webView stringByEvaluatingJavaScriptFromString:@"navigator.userAgent"];
NSString *uaa = [useragent stringByAppendingString:@"iosclient"];//自定义需要拼接的字符串
NSDictionary *dictionary = [NSDictionary dictionaryWithObjectsAndKeys:uaa, @"UserAgent",@"ww", nil];
[[NSUserDefaults standardUserDefaults] registerDefaults:dictionary];
self.title = [webView stringByEvaluatingJavaScriptFromString:@"document.title"];
ios开发 设置webview的userAgent
