Question

我正在检查我的应用程序与iOS 8的兼容性，我正在关注登录控制台＆＃34;尝试标记应用程序图标，但尚未获得用户的许可以标记应用程序＆＃34 ; 。任何人都可以帮我摆脱这个警告。是的，我的应用程序在App Icon和TabBar Icon上显示徽章。

Answer 1

以下是我在AppDelegate中所做的事情

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // registering for remote notifications
    [self registerForRemoteNotification];
    return YES;
}


- (void)registerForRemoteNotification {
    if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8.0")) {
        UIUserNotificationType types = UIUserNotificationTypeSound | UIUserNotificationTypeBadge | UIUserNotificationTypeAlert;
        UIUserNotificationSettings *notificationSettings = [UIUserNotificationSettings settingsForTypes:types categories:nil];
        [[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];
    } else {
        [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
    }
}

#ifdef __IPHONE_8_0
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings {
    [application registerForRemoteNotifications];
}
#endif

Apple为注册通知和使用徽章制作了新的API。

参见WWDC 2014会话视频： https://developer.apple.com/videos/wwdc/2014/?id=713， http://asciiwwdc.com/2014/sessions/713（正文版）和 https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIApplication_Class/index.html#//apple_ref/occ/instm/UIApplication/registerUserNotificationSettings：

用户可以更改“设置”中每个UIUserNotificationType (UIUserNotificationTypeBadge, UIUserNotificationTypeSound, UIUserNotificationTypeAlert)的权限。

在更改徽章之前，您必须检查权限。

来自AppDelegate的代码示例：

- (BOOL)checkNotificationType:(UIUserNotificationType)type
{
  UIUserNotificationSettings *currentSettings = [[UIApplication sharedApplication] currentUserNotificationSettings];
  return (currentSettings.types & type);
}

- (void)setApplicationBadgeNumber:(NSInteger)badgeNumber
{
  UIApplication *application = [UIApplication sharedApplication];

  if(SYSTEM_VERSION_LESS_THAN(@"8.0")) {
    application.applicationIconBadgeNumber = badgeNumber;
  }
  else {
    if ([self checkNotificationType:UIUserNotificationTypeBadge]) {
      NSLog(@"badge number changed to %d", badgeNumber);
      application.applicationIconBadgeNumber = badgeNumber;
    }
    else {
      NSLog(@"access denied for UIUserNotificationTypeBadge");
    }
  }
}

#define SYSTEM_VERSION_LESS_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)

UI应用程序实例中提供了currentUserNotificationSettings方法，它将为您提供最新的用户通知首选项。

使用徽章编号：

[self setApplicationBadgeNumber:0];

而不是

application.applicationIconBadgeNumber = 0;

Answer 3

您可以使用

    #if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000
        if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)])
        {
[[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
            [[UIApplication sharedApplication] registerForRemoteNotifications];
        } else
        {
            [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
             (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
        }
    #else
       [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
         (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
    #endif

Answer 4

我在寻找Swift的解决方案时遇到了这个答案。我做了以下（假设iOS 8）：

UIApplication.sharedApplication().registerUserNotificationSettings(UIUserNotificationSettings(forTypes: UIUserNotificationType.Sound | UIUserNotificationType.Alert | UIUserNotificationType.Badge, categories: nil))
UIApplication.sharedApplication().registerForRemoteNotifications()

Answer 5

不是检查IOS版本，而是检查UIUserNotificationSettings是否存在并注册BadgeType，就像我们以前用过远程通知一样。

Class userNotification = NSClassFromString(@"UIUserNotificationSettings");

if (userNotification)
{
    UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil];
    [[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];
}

Answer 6

如果您想使用本地通知，请使用以下代码：

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000 


    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
    [[UIApplication sharedApplication] registerForRemoteNotifications];

#else

    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
 (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];

#endif

Answer 7

iOS 8有一个名为registerUserNotificationSettings:的应用程序方法。部分文档说：“如果您的应用在后台显示警报，播放声音或标记其图标，则必须在启动周期中调用此方法，以请求以这些方式提醒用户的权限。”

Answer 8

您可以使用

if(SYSTEM_VERSION_LESS_THAN(@"8.0"))
{
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
     (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
}
else
{
    [[UIApplication sharedApplication] registerForRemoteNotifications];
}

....

#define SYSTEM_VERSION_LESS_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)

对于推送通知，我认为它会解决它，在我的情况下在模拟器上我得到这个警告，因为它不支持推送我用户拒绝许可，而不是再次你会有这个警告。谢谢。

+ (BOOL)canBadgeTheApp {
    BOOL canBadgeTheApp;
    if ([UIDevice currentDevice].systemVersion.doubleValue >= 8) {
        UIUserNotificationType types = [[[UIApplication sharedApplication] currentUserNotificationSettings] types];
        canBadgeTheApp = ((types & UIRemoteNotificationTypeBadge) != 0);
    } else {
        canBadgeTheApp = YES;
    }
    return canBadgeTheApp;
}

＆＃34; swifters＆＃34;上面的代码：

final func checkNotificationType(type : UIUserNotificationType) -> Bool {

    let application = UIApplication.sharedApplication()
    if application.respondsToSelector(Selector("registerUserNotificationSettings:")) {
        // iOS8 and above
        let currentSettings : UIUserNotificationSettings = application.currentUserNotificationSettings()
        let types = currentSettings.types
        return types.rawValue & type.rawValue > 0
    }else{
        return true
    }
}

Answer 11

你唯一需要的是

if (floor(NSFoundationVersionNumber) >= NSFoundationVersionNumber_iOS_8_0)       {
// here you go with iOS 8
} else {

}
