iOS状态栏隐藏

在做葡萄相机的时候，使用 项目 info.plist  文件配置的方法，隐藏了所有的页面导航栏。但是在做滤镜选项卡页面的时候，自定义了一个 视图。里面有一个 UIWindow 对象。重新指定了根视图，于是，这个页面状态栏又出现了。发现无法用代码控制隐藏。

#define MOVE_DISTANCE 7

@interface EditViewControllerCustomScrollView()
{
    //关闭、确定 按钮
    UIButton *cancelButton;
    UIButton *confirmButton;
    
    UIScrollView *filterScrollView; //当前页面显示滚动视图，在当前页面切换滤镜效果
    NSMutableArray *filterImageArr;  //保存9 种滤镜效果数组
    NSMutableArray *filterTitleArr;  //保存9 种滤镜名称数组
    
    NSInteger selectedFilter;
}

@property (nonatomic, assign) CGRect         screenRect;      //当前屏幕尺寸，兼容横竖屏幕
@property (nonatomic, strong) UIWindow       *window;         //弹出 Sheet 所在Window
@property (nonatomic, strong) UIView         *dimBackground;  //弹出后，原来的视图覆盖的背景

@end


@implementation EditViewControllerCustomScrollView

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.

再配置一个 plist 属性

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.
