Question

我知道如何删除状态栏，但这会自动将我的导航控制器及其导航栏捕捉到屏幕顶部。

如何删除状态栏但保留屏幕顶部的20 px空间，以便将自己的自定义视图或窗口放在该空间中？

Answer 1

创建自定义UINavigationController并覆盖viewDidAppear

    - (void)viewDidAppear:(BOOL)animated
    {
        [super viewDidAppear:animated];
        CGRect f = self.view.frame;
        self.view.frame = CGRectMake(0,20,f.size.width,f.size.height-20);
        //the custom view for replacing the status bar.
        //you can add any custom subview you want 
        UIView *iv = [[UIView alloc]initWithFrame:CGRectMake(0,0,320,20)];
        //assign a color with alpha less than 1.0 to make it translucent
        iv.backgroundColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.5];
        //remember to remove the iv when you don't need the navigation controller any more.
        [self.view.window insertSubview:iv aboveSubview:self.view];
    }
