iOS-混合开发去掉状态栏高度

第一步：在pist文件添加 View controller-based status bar appearance 字段并设为YES

第二步：在controller中添加如下代码

• (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.
  if([[[UIDevice currentDevice] systemVersion] floatValue] >= 7){
  CGRect viewBounds = [self.webView bounds];
  viewBounds.origin.y = -20;
  viewBounds.size.height = viewBounds.size.height;
  self.webView.frame = viewBounds;
  }

  [super viewWillAppear:animated];

这样就完美的去掉的状态栏的高度
