如何在状态栏中检测触摸

最后,我根据这里的答案整理出了有效的解决方案。谢谢你们。

在某处声明通知名称(例如AppDelegate.h):

static NSString * const kStatusBarTappedNotification = @"statusBarTappedNotification";

#pragma mark - Status bar touch tracking
- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [super touchesBegan:touches withEvent:event];
    CGPoint location = [[[event allTouches] anyObject] locationInView:[self window]];
    CGRect statusBarFrame = [UIApplication sharedApplication].statusBarFrame;
    if (CGRectContainsPoint(statusBarFrame, location)) {
        [self statusBarTouchedAction];
    }
}

- (void)statusBarTouchedAction {
    [[NSNotificationCenter defaultCenter] postNotificationName:kStatusBarTappedNotification
                                                        object:nil];
}

注意所需控制器中的通知(例如,在viewWillAppear中):

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(statusBarTappedAction:)             
                                             name:kStatusBarTappedNotification
                                           object:nil];

正确移除观察者(例如,在视图中):

[[NSNotificationCenter defaultCenter] removeObserver:self name:kStatusBarTappedNotification object:nil];

- (void)statusBarTappedAction:(NSNotification*)notification {
    NSLog(@"StatusBar tapped");
    //handle StatusBar tap here.
}

希望能有帮助。

Swift 3更新

在iOS9+上测试并运行。

在某处声明通知名称:

let statusBarTappedNotification = Notification(name: Notification.Name(rawValue: "statusBarTappedNotification"))

跟踪状态栏并发布通知。将以下行添加到AppDelegate.swift应用程序:

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    super.touchesBegan(touches, with: event)

    let statusBarRect = UIApplication.shared.statusBarFrame
    guard let touchPoint = event?.allTouches?.first?.location(in: self.window) else { return }

    if statusBarRect.contains(touchPoint) {
        NotificationCenter.default.post(statusBarTappedNotification)
    }
}

必要时遵守通知:

NotificationCenter.default.addObserver(forName: statusBarTappedNotification.name, object: .none, queue: .none) { _ in
    print("status bar tapped")
}

这是我目前的解决方案,效果非常好。但请你带上其他的想法,因为我不太喜欢。。。

• 在视图中的某处添加滚动视图。或者把它藏起来,或者放在其他地方。
• 设置其 contentSize
• 设置非零 contentOffset
• 在您的控制器中,实现如下所示的scrollview的委托。

总是回来 NO ,滚动视图从不向上滚动,每当用户点击状态栏时就会收到通知。然而,问题是,这不适用于“真正的”内容滚动视图。(见问题)

- (BOOL)scrollViewShouldScrollToTop:(UIScrollView *)scrollView
{
    // Do your action here
    return NO;
}

将此添加到您的AppDelegate.swift应用程序会做你想做的事:

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
    super.touchesBegan(touches, withEvent: event)
    let events = event!.allTouches()
    let touch = events!.first
    let location = touch!.locationInView(self.window)
    let statusBarFrame = UIApplication.sharedApplication().statusBarFrame
    if CGRectContainsPoint(statusBarFrame, location) {
        NSNotificationCenter.defaultCenter().postNotificationName("statusBarSelected", object: nil)
    }
}

NSNotificationCenter.defaultCenter().addObserverForName("statusBarSelected", object: nil, queue: nil) { event in

    // scroll to top of a table view
    self.tableView!.setContentOffset(CGPointZero, animated: true)
}

找到了一个更好的解决方案,它与iOS7兼容: http://ruiaureliano.tumblr.com/post/37260346960/uitableview-tap-status-bar-to-scroll-up

- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [super touchesBegan:touches withEvent:event];
    CGPoint location = [[[event allTouches] anyObject] locationInView:[self window]];
    if (CGRectContainsPoint([UIApplication sharedApplication].statusBarFrame, location)) {
        NSLog(@"STATUS BAR TAPPED!");
    }
}

我通过在状态栏上添加一个清晰的UIView来实现这一点,然后拦截touch事件

应用程序中的第一个代理ap应用程序:使用选项完成启动:添加这两行代码:

self.window.backgroundColor = [UIColor clearColor];
self.window.windowLevel = UIWindowLevelStatusBar+1.f;

然后在要截获状态栏点击的视图控制器中(或在应用程序委托中)添加以下代码

UIView* statusBarInterceptView = [[[UIView alloc] initWithFrame:[UIApplication sharedApplication].statusBarFrame] autorelease];
statusBarInterceptView.backgroundColor = [UIColor clearColor];
UITapGestureRecognizer* tapRecognizer = [[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(statusBarClicked)] autorelease];
[statusBarInterceptView addGestureRecognizer:tapRecognizer];
[[[UIApplication sharedApplication].delegate window] addSubview:statusBarInterceptView];

在statusBarClicked选择器中,执行您需要执行的操作,在我的示例中,我向通知中心发布了一个通知,以便其他视图控制器可以响应状态栏点击。

谢谢,麦克斯,你的解决方案在我花了很长时间寻找之后对我有效。

dummyScrollView = [[UIScrollView alloc] init];
dummyScrollView.delegate = self;
[view addSubview:dummyScrollView];
[view sendSubviewToBack:dummyScrollView];   

然后

  dummyScrollView.contentSize = CGSizeMake(view.frame.size.width, view.frame.size.height+200);
  // scroll it a bit, otherwise scrollViewShouldScrollToTop not called
  dummyScrollView.contentOffset = CGPointMake(0, 1);  

//delegate :
- (BOOL)scrollViewShouldScrollToTop:(UIScrollView *)scrollView
{
  // DETECTED! - do what you need to
  NSLog(@"scrollViewShouldScrollToTop");
  return NO;
}

请注意,我也有一个UIWebView,我不得不用我在某处找到的一个解决方案进行一些修改:

- (void)webViewDidFinishLoad:(UIWebView *)wv
{  
  [super webViewDidFinishLoad:wv];  

  UIScrollView *scroller = (UIScrollView *)[[webView subviews] objectAtIndex:0];
  if ([scroller respondsToSelector:@selector(setScrollEnabled:)])
    scroller.scrollEnabled = NO; 
}

UIScrollView

override func viewDidLoad() {
    let scrollView = UIScrollView()
    scrollView.bounds = view.bounds
    scrollView.contentOffset.y = 1
    scrollView.contentSize.height = view.bounds.height + 1
    scrollView.delegate = self
    view.addSubview(scrollView)
}

func scrollViewShouldScrollToTop(_ scrollView: UIScrollView) -> Bool {
    debugPrint("status bar tapped")
    return false
}

您可以使用以下代码跟踪状态栏点击:

[[NSNotificationCenter defaultCenter] addObserverForName:@"_UIApplicationSystemGestureStateChangedNotification"
                                                  object:nil
                                                   queue:nil
                                              usingBlock:^(NSNotification *note) {
        NSLog(@"Status bar pressed!");
}];

如果你只是想 UIScrollView 视图控制器正好有一个 在其子视图中 scrollsToTop 设置为 YES

UIScrollView公司 (或子类: UITableView , UICollectionView ,并设置 滚动桌面 成为 NO .

post that was linked to 在原来的问题,但它也被驳回,因为不再工作,所以我跳过它,只找到了后续搜索相关的一块。

对于iOS 13来说,这对我来说很有效,Objective-C类别 UIStatusBarManager

@implementation UIStatusBarManager (CAPHandleTapAction)
-(void)handleTapAction:(id)arg1 {
    // Your code here
}
@end
