For example, achieve the following results:

The background is a translucent masked layer effect. After you click it, the background disappears.

How to Implement the masked layer:

1. initialize UIView as the background layer

2. Set the opaque attribute and background color of the background View.

3. Add UIGestureRecognizer to respond to background touch operations

4. Add the background view to the window and modify the background color.

5. Remove the view and modify the background color in the area to be hidden.

Some code:

    //background init and tapped    UIView *background = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height)];    background.backgroundColor = [UIColor colorWithWhite:0.0 alpha:0.0];    background.opaque = NO;    UIGestureRecognizer *gesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(backgroundTapped:)];    [background addGestureRecognizer:gesture];    self.shareBackGroundView = background;

    self.shareBackGroundView.backgroundColor = [UIColor colorWithWhite:0.0 alpha:0.3];        AppDelegate *delegate = (AppDelegate *)[UIApplication sharedApplication].delegate;    [delegate.window addSubview:self.shareBackGroundView];

    self.shareBackGroundView.backgroundColor = [UIColor colorWithWhite:0.0 alpha:0.0];    [self.shareBackGroundView removeFromSuperview];
