iphone - phonegap - webViewDidFinishLoad 没有被调用

Question

我正在使用 Phonegap2.1。我的 AppDelegate.m 文件中有 webViewDidFinishLoad 方法。它曾经在以前的 phonegap 版本中被自己调用。现在，它根本不会被调用。我需要将委托(delegate)分配到某个地方吗？

- (void)webViewDidFinishLoad:(UIWebView *)theWebView 
{
if(self.invokeString)
{
    // this is passed before the deviceready event is fired, so you can access it in js when you receive deviceready
    NSString* jsString = [NSString stringWithFormat:@"var invokeString = \"%@\";", self.invokeString];
    [theWebView stringByEvaluatingJavaScriptFromString:jsString];
}
// Black base color for background matches the native apps
theWebView.backgroundColor = [UIColor blackColor];

return [ self.viewController webViewDidFinishLoad:theWebView ];
}

当您升级到 2.1.0 时，建议您注释掉所有该部分，因为它已被弃用。在使用 cordova 2.1.0 时，您提供的代码实际上对您没有任何帮助，因此如果您将其注释掉，您的应用程序应该可以正常工作。

    #pragma UIWebDelegate implementation
    /*
    - (void) webViewDidFinishLoad:(UIWebView*) theWebView
    {
    // only valid if ___PROJECTNAME__-Info.plist specifies a protocol to handle
    if (self.invokeString)
    {
    // this is passed before the deviceready event is fired, so you can access it in js when you receive        deviceready
    NSLog(@"DEPRECATED: window.invokeString - use the window.handleOpenURL(url) function instead, which is    always called when the app is launched through a custom scheme url.");
    NSString* jsString = [NSString stringWithFormat:@"var invokeString = \"%@\";", self.invokeString];
    [theWebView stringByEvaluatingJavaScriptFromString:jsString];
    }

   // Black base color for background matches the native apps
   theWebView.backgroundColor = [UIColor blackColor];

  return [super webViewDidFinishLoad:theWebView];
  }*/

保留此部分未注释会给出此警告:

 Classes/MainViewController.m:133:11: 'invokeString' is deprecated
 Classes/MainViewController.m:137:86: 'invokeString' is deprecated

您的应用可以正常运行，但发布带有警告的产品并不理想。

除非你故意不让全世界看到你的代码
