Ios 在导航栏中添加自定义视图，如whatsapp

我想创建自定义导航栏，如WhatsApp用于在应用程序中显示呼叫指示器，如下所示

@property (nonatomic) UIView *navigationBarTopView;

UIWindow *window = [UIApplication sharedApplication].keyWindow;
if (_navigationBarTopView == nil) {
    _navigationBarTopView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, window.frame.size.width, 60.0)];
        [_navigationBarTopView setBackgroundColor:[UIColor colorWithRed:76.0/255.0 green:217.0/255.0 blue:100.0/255.0 alpha:1]];

    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, _navigationBarTopView.frame.size.height - 15, window.frame.size.width, 10)];
    [label setText:@"Touch to return to call"];
    [label setTextColor:[UIColor whiteColor]];
    [label setFont:[UIFont preferredFontForTextStyle:UIFontTextStyleFootnote]];
    [label setTextAlignment:NSTextAlignmentCenter];
    [_navigationBarTopView addSubview:label];

    //The setup code (in viewDidLoad in your view controller)
    UITapGestureRecognizer *singleFingerTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];
    [_navigationBarTopView addGestureRecognizer:singleFingerTap];

    UITapGestureRecognizer *singleFingerTap1 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];
    [label addGestureRecognizer:singleFingerTap1];
}

[window addSubview:_navigationBarTopView];

我已经成功地添加了如上所述的视图，但它没有响应，因为我无法检测到状态栏上的触摸。我只能触摸“触摸返回呼叫”下面的部分

代码如下所示

@property (nonatomic) UIView *navigationBarTopView;

UIWindow *window = [UIApplication sharedApplication].keyWindow;
if (_navigationBarTopView == nil) {
    _navigationBarTopView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, window.frame.size.width, 60.0)];
        [_navigationBarTopView setBackgroundColor:[UIColor colorWithRed:76.0/255.0 green:217.0/255.0 blue:100.0/255.0 alpha:1]];

    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, _navigationBarTopView.frame.size.height - 15, window.frame.size.width, 10)];
    [label setText:@"Touch to return to call"];
    [label setTextColor:[UIColor whiteColor]];
    [label setFont:[UIFont preferredFontForTextStyle:UIFontTextStyleFootnote]];
    [label setTextAlignment:NSTextAlignmentCenter];
    [_navigationBarTopView addSubview:label];

    //The setup code (in viewDidLoad in your view controller)
    UITapGestureRecognizer *singleFingerTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];
    [_navigationBarTopView addGestureRecognizer:singleFingerTap];

    UITapGestureRecognizer *singleFingerTap1 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];
    [label addGestureRecognizer:singleFingerTap1];
}

[window addSubview:_navigationBarTopView];

我还尝试在状态栏上添加触摸，如下所示，但它不起作用

此外，导航栏也不会出现问题。我已尝试设置

keyWindow

frame。但这也不起作用。

我也尝试了singleViewcontroller和UITabbar Controller，我附加的示例项目，用于我遵循的状态栏点击操作

UIStatusBar的优先级高于应用程序的窗口，因此您不会通过状态栏获得任何触摸事件

要通过状态栏获取触摸事件，您需要一个窗口级别高于UIStatusBar的窗口

请尝试以下代码：

#import "AppDelegate.h"

@interface AppDelegate ()

@property (nonatomic) UIWindow *buttonWindow;
@property (nonatomic) UIWindow *textWindow;
@property (nonatomic) CGFloat callViewHeight;

@end

@implementation AppDelegate

    // Override point for customization after application launch.
        if (@available(iOS 11.0, *)) {
        if (([[[UIApplication sharedApplication] delegate] window].safeAreaInsets.top > 20.0)) {
            self.callViewHeight = 55.0f;
        } else {
            self.callViewHeight = 35.0f;
        }
    } else {
        self.callViewHeight = 35.0f;
    }
    return YES;
}

    lblName.text = @"";

您确定这不是系统

调用栏

？请尝试此

[self.navigationController.view addSubview:\u navigationBarTopView]它是系统生成的导航栏。它在与任何人通话时自动显示。呼叫可以是普通或VoIP（由SDK管理）。如果需要，您可以将自定义视图添加到导航栏。如果您想创建相同的视图，这是apple提供的默认行为，如将子视图添加到顶部的navigationController.viewviewcontroller@iMHiteshSurani我不会把它加入应用程序。我已经实现了同样的Twilio语音SDK。因此，我创建了自定义视图，并将其添加为屏幕顶部的UIWindow。仅供参考：具有可用安全区域呼叫功能的设备与非安全区域设备不同。它将在状态栏中显示一个小的呼叫图标bar@Anbu.Karthik我已经实现了这段代码，但使用这段代码我无法接触到状态栏。此外，我有一个复杂的结构，其中包括一个选项卡栏和4个导航栏控制器。所以很难在应用程序中进行管理。要在状态栏上显示触摸事件，我正在使用此解决方案。但它在选项卡栏上不起作用。它与单视图控制器配合良好。请使用此库进行同样的操作。我知道，可能需要一些定制，但它将易于使用和评级是好的@JayeshSojitra-我更新了答案，它也适用于单视图控制器和UITabbar控制器，请检查谢谢@iDhaval此解决方案有效。我已经做了一些更改，使其与iPhone X+设备兼容。您好，有没有针对swift的解决方案？@iDhaval，我尝试过，但在xcode 11中不起作用。6@swift2geek你面临什么问题？
