如何在iOS半透明中制作PhoneGap状态栏？

- (void)webViewDidFinishLoad:(UIWebView *)theWebView 
{
    // only valid if StatusBarTtranslucent.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
        NSString* jsString = [NSString stringWithFormat:@"var invokeString = "%@";",self.invokeString];
        [theWebView stringByEvaluatingJavaScriptFromString:jsString];
    }

    [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleBlackTranslucent;

    CGRect frame = theWebView.frame;
    NSLog(@"The WebView: %f %f %f %f",frame.origin.x,frame.origin.y,frame.size.width,frame.size.height);
    frame = theWebView.superview.frame;
    NSLog(@"The WebView superview: %f %f %f %f",frame.size.height);

    frame.size.height += frame.origin.y;
    frame.origin.y = 0;

    [theWebView.superview setFrame:frame];

    return [ super webViewDidFinishLoad:theWebView ];
}

此代码的日志结果显示：

The WebView: 0.000000 0.000000 320.000000 460.000000
The WebView superview: 0.000000 20.000000 320.000000 460.000000

所以修复webview.superview框架可以获得UIStatusBarTranslucent的效果

CGRect frame = theWebView.superview.frame;

frame.size.height += frame.origin.y;
frame.origin.y = 0;

[theWebView.superview setFrame:frame];
