在做葡萄相機的時候，使用 項目 info.plist? 文件配置的方法，隱藏了所有的頁面導航欄。但是在做濾鏡選項卡頁面的時候，自定義了一個 視圖。里面有一個 UIWindow 對象。重新指定了根視圖，于是，這個頁面狀態欄又出現了。發現無法用代碼控制隱藏。

You can create a custom UIView with its frame as

customView.frame=CGRectMake(0, 20, self.view.frame.size.width, self.view.frame.size.height);

Also hide your status bar by following the below steps

Go to info.plist and add two attributes if not present. set "Status bar is initially hidden" to YES and set UIViewControllerBasedStatusBarAppearance to NO. This will hide status bar for your app.

再配置一個 plist 屬性

Add this code in your view Controller: if ([self respondsToSelector:@selector(setEdgesForExtendedLayout:)]) {self.edgesForExtendedLayout = UIRectEdgeNone; }

I had to do this once.. I ended up creating a custom navigation bar of my own and then just set the frame as: navBar.frame=CGRectMake(0, 20, self.view.frame.size.width, self.view.frame.size.height); It worked for me at the time,…just try it out.
