iOS調用WebView私人API的方法

來源:互聯網
上載者:User

   - (void)modifyUA

  {

  id webView = [uiWebViewInstance valueForKeyPath:@"_internal.browserView._webView"];

  [webView performSelector:@selector(setCustomUserAgent:) withObject:@"Mozilla/5.0 (Windows; U; Windows NT 5.2) AppleWebKit/525.13 (KHTML, like Gecko) Chrome/0.2.149.27 Safari/525.13 "];

  }

  這是樣本修改User Agent。擷取WebView使用的是Key-Value Coding的方法

  為了更安全地通過apple的審查,可以這樣:

  - (void)modifyUA

  {

  NSString *path = [@"_internal.browser" stringByAppendingString:@"View._webView"];

  id webView = [g_webView valueForKeyPath:path];

  NSString *selString = [@"setCustom" stringByAppendingString:@"UserAgent:"];

  SEL sel = NSSelectorFromString(selString);

  [webView performSelector:sel withObject:@"Mozilla/5.0 (Windows; U; Windows NT 5.2) AppleWebKit/525.13 (KHTML, like Gecko) Chrome/0.2.149.27 Safari/525.13 "];

  }

  把字串分割再合成就ok
