Phonegap在ios7上系统状态栏的问题解决

用Phonegap+jqm开发的应用，在ios6下没问题，但是在ios7下会出现如下系统状态栏和header重合的问题，搜索了一下，发现这其实是 phonegap当前版本的一个已知问题，通过修改./platforms/ios/whhe/Classes /MainViewController.m，就可以解决

    - (void)viewWillAppear:(BOOL)animated  
    {  
    // View defaults to full size.  If you want to customize the view's size, or its subviews (e.g. webView),  
    // you can do so here.  
    //Lower screen 20px on ios 7  
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {  
        CGRect viewBounds = [self.webView bounds];  
        viewBounds.origin.y = 20;  
        viewBounds.size.height = viewBounds.size.height - 20;  
        self.webView.frame = viewBounds;  
    }  
    [super viewWillAppear:animated];  
    }
