场景如下：

解决方案：控制webview的frame，顶部添加20的view
代码如下：
- (void)viewDidLoad
{
[super viewDidLoad];
self.edgesForExtendedLayout = UIRectEdgeNone;
UIView *statusBarView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, 20)];
statusBarView.backgroundColor = [HTMISettingManager manager].navigationBarColor;
[self.view addSubview:statusBarView];
}
- (void)viewWillAppear:(BOOL)animated
{
CGRect viewBounds = [self.webView bounds];
viewBounds.origin.y = 20;
viewBounds.size.height = viewBounds.size.height - 20;
self.webView.frame = viewBounds;
[super viewWillAppear:animated];
}
