iOS13: how to detect a status bar click event?

问题

In my appDelegate, I override touchesBegan to detect when the status bar is clicked:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [super touchesBegan:touches withEvent:event];

    CGPoint location = [[[event allTouches] anyObject] locationInView:kWindow];
    CGRect statusBarFrame = [UIApplication sharedApplication].statusBarFrame;

    if (CGRectContainsPoint(statusBarFrame, location)) {
        ///do something 
    }
}

Before iOS 13, this worked; on iOS 13, it does not. The method is never executed. How can I fix this?

回答1:

After some research, I found that the status bar is no longer part of the application on iOS13, it’s part of the system UI (“springboard”). You need to access it via UIStatusBarManager

So this no longer works:

CGRect statusBarFrame = [UIApplication sharedApplication].statusBarFrame;

In iOS 13, you need to get the StatusBar frame like this:

UIStatusBarManager *manager = [UIApplication sharedApplication].keyWindow.windowScene.statusBarManager;
CGRect statusBarFrame = manager.statusBarFrame;

回答2:

In iOS 13, StatusBar Event was managed by UIStatusBarManager, these methods will be called when click the StatusBar:

-[UIStatusBarManager _handleScrollToTopAtXPosition:]
-[UIStatusBarManager handleTapAction:]

So, you can hook -[UIStatusBarManager handleTapAction:] to detecte StatusBar click event
